Le leasing fait l’objet d’un nombre limité de travaux académiques, notamment sur une problématique qui lui est propre, le risque de valeur résiduelle. Dans l’activité de leasing, le bailleur prend le risque de ne pas récupérer su¢ samment de capital lors de la revente de l’actif. Le risque de perte à la revente à la …n de la période contractuelle, ainsi que la tari…cation sont fortement impactés par le prix estimé de revente de l’actif (la valeur résiduelle). La thèse vise à fournir une contribution académique aux professionnels en charge de la gestion de ce risque dans le secteur du leasing. Trois thèmes sont abordés : la valorisation des actifs, la couverture des risques de valeur résiduelle, et la dimension macro-économique. Dans le premier chapitre, nous appliquons la méthode des prix hédoniques à un portefeuille européen de leasing, a…n d’estimer la distribution des prix de revente d’automobiles. L’approche hédonique estime le prix d’un bien par la valorisation de ses attributs. Suite à une discussion sur les prix hédoniques, nous proposons un modèle opérationnel pour le marché de l’automobile d’occasion. Le modèle est appliqué à quatre pays européens (l’Allemagne, l’Espagne, la France et la Grande-Bretagne), et les distributions sont calculées sur deux modèles de véhicules (Audi A4 et Ford Focus) permettant la comparaison des pro…ls de dépréciation et des risques de valeur résiduelle. Mots-clés : modèles hédoniques, valeur résiduelle, marché automobile. Classi…cation JEL : C51, G12, G32, D12. Dans le deuxième chapitre, nous proposons un modèle statistique pour couvrir le risque de valeur résiduelle en utilisant la technique des copules gaussiens. A la suite d’une discussion sur la problématique du risque de valeur résiduelle et des modèles de risque de crédit existants, un nouveau produit dérivé est proposé et analysé : le Collateralized Residual Value (CRV). v vi RÉSUMÉ Le modèle est appliqué à un portefeuille européen de location longue durée d’automobiles. Nos résultats indiquent que ce produit …nancier est facile à adapter et à mettre en œuvre en fonction des caractéristiques du contrat et de la corrélation entre les actifs le composant. Mots-clés : risque de valeur résiduelle, risque de crédit, produits dérivés de crédit, modèle factoriel, copules. Classi…cation JEL : C10, G13. Le dernier chapitre répond à deux questions cruciales dans le secteur du leasing automobile : Quelles sont les interactions entre les automobiles neuves et d’occasion ? Pouvons-nous utiliser ces interactions a…n d’estimer le prix de revente des véhicules ? Les voitures neuves d’aujourd’hui seront les voitures d’occasion de demain, et l’on suppose une forme de compétition entre le marché du neuf et le marché de l’occasion. C’est pourquoi il existe quelques idées préconçues et de nombreuses théories sur les interactions entre le premier marché et le second marché. Nous proposons de développer la ré‡exion par une analyse macro-économique des marchés automobiles Français, Britanniques et Nord-Américains. Les di¤érents concepts sont répertoriés et statistiquement contrôlés. Nos résultats indiquent que les relations entre les di¤érents marchés semblent limitées en France et au Royaume-Uni, alors que le marché NordAméricain est confronté à un mécanisme dit de ‘Scitovscky’. Dans tous les cas, les relations ne sont pas assez fortes pour expliquer complètement les comportements des marchés.

Summary Leasing, by its volume and its attributes, constitutes a signi…cant mean of …nancing in the world. Leasing, however, sparked o¤ a limited academic interest, many of its features have been unexplored and particularly on a critical point, the residual value risk. In the leasing industry the lessor faces a risk, at the end of the contract, in not recovering su¢ cient capital value from resale of the asset. The risk of loss on sales at the end of the contract term, as well as pricing, are critically impacted by the forecasted resale price of the asset (residual value). The thesis aims to provide an academic contribution directed at asset analysts in charge of residual value in the leasing industry. Three topics are discussed : asset valuation, residual value risk hedging, and macro economy perspective. In the …rst chapter, we apply the Hedonic methodology to European auto lease portfolios, in order to estimate the resale price distribution. The Hedonic approach estimates the price of a good through the valuation of its attributes. Following a discussion on Hedonic prices, we propose an operational model for the automobile resale market. The model is applied to four European countries (France, Germany, Spain and Great Britain), and distributions are calculated on two vehicle versions (Audi A4 and Ford Focus) allowing a comparison of market depreciation patterns and residual value risks. Keywords : Hedonic model, residual value, automotive market. JEL Classi…cation : C51, G12, G32, D12. In the second chapter, we propose a model to hedge residual value risk using the Gaussian copula methodology. After discussing residual value risk and credit risk modelization, a new derivative product is introduced and analyzed ; the Collateralized Residual Values (CRV). The model is applied to an European auto lease portfolio of operating lease contracts pertaining to a major company. Our results indicate that the …nancial product is easy to customize, and to implement through the contract characteristics and the level of correlation. vii viii SUMMARY Keywords : residual value risk, credit risk, credit derivatives, factor modeling, copula. JEL Classi…cation : C10, G13. In the third chapter, we aim at answering two critical questions of the Auto lease industry. What are the interactions between the new and the second-hand car markets ? Can we use the interactions to estimate the car prices of tomorrow ? Everybody knows that the new cars of today are used cars of tomorrow and some people assume a competition between new and used markets. There are numerous, preconceived ideas and academic theories regarding the interactions between primary and secondary markets. To investigate the relations, we provide a macroeconomic analysis of the French, the British and the US car markets. Our results indicate that the relations appear limited for France and the UK, whereas the US market faces a Scitovscky mechanism. Furthermore, they illustrate that the interrelations are not strong enough to fully explain and forecast market patterns.

P. Bourdieu, Homo Academicus, Les Editions de Minuit, 1984, p17. L’activité de leasing est peu connue bien qu’elle constitue une part importante de l’économie mondiale. L’International Accounting Standard for Lease, ou IAS171 dé…nit un contrat de leasing comme «un accord par lequel le bailleur cède au locataire, en échange d’un paiement ou une série de paiements, le droit d’utiliser un actif pendant une période de temps convenue» . Cependant, la législation peut être di¤érente selon les pays, les contrats peuvent être adaptés pour répondre aux besoins d’un client et tout type d’équipement peut, en théorie, faire l’objet de leasing. Ainsi le mot ‘lease’comprend un large éventail de contrats. Dans l’ensemble, le leasing est un instrument …nancier pour l’achat de matériel. Dans un contrat de leasing, le bailleur fournit un équipement qui doit être utilisé par un locataire sur une période dé…nie en échange de paiements spéci…és. Le bien loué peut être tout type de matériel (imprimante, scanner, camions, avions...) utilisé par le locataire à des …ns commerciales. Le bailleur achète l’équipement et il est le propriétaire légal de l’actif. Pour utiliser l’équipement, le locataire verse des paiements périodiques au bailleur tout au long de la période du contrat. 1 Au sein de l’Union européenne, toutes les sociétés cotées sont tenues d’adopter l’IAS17. La norme équivalente aux USA est le SAF13. xiii xiv INTRODUCTION GÉNÉRALE L’ensemble du marché du leasing mondial2 a été estimé à plus de 633 milliards de dollars en 2006. L’Europe et L’Amérique du Nord ont représenté 41% et 38% du marché mondial. Le ‘World Leasing Yearbook 2009’ a rapporté un montant global d’équipement en leasing de plus de 760 milliards de dollars pour 2007. Les associations européennes de leasing ont enregistré un volume de crédit-bail neuf au-dessus de 330 milliards d’Euros et une contribution au …nancement, en moyenne, de 18% du total des investissements européens pour 2008. Par ailleurs, le leasing a impliqué plus de 16 millions d’automobiles en Europe3 . D’une manière générale, les contributions academiques traitant du sujet sont quasiment toutes liées à la comparaison entre le leasing et l’acquisition d’un équipement par le crédit. Certains papiers analysent les avantages …scaux résultant du choix entre un contrat de leasing et le recours à un emprunt4 . Un deuxième groupe d’articles académiques discutent du ‘Leasing Puzzle’. Les théories en …nance et en economie suggèrent que les contrats de leasing et les emprunts sont des substituts. Ainsi, une augmentation du leasing devrait conduire à une diminution de la dette. De plus, les théories …nancières standard gèrent les ‡ux de trésorerie provenant des contrats de leasing de la même manière que ceux provenant des crédits. Mais Ang et Peterson (1984) ont constaté empiriquement que le leasing et la dette apparaissent, en fait, comme des compléments pour les entreprises. Un accroissement du leasing est associé à un accroissement de la dette. Ne pouvant avancer une explication concluante, ils quali…èrent leur découverte d’énigme non résolue de la …nance ou de ’Leasing Puzzle’. À la suite de leur article fondateur, plusieurs recherches académiques ont tenté de reproduire et de véri…er les résultats5 . Le ‘Puzzle’nous amène au troisième domaine de recherche qui couvre tous les articles liés aux incitations au leasing et à ses avantages. Lasfer et Lévis (1998), par exemple, ont reformulé le problème. En théorie, le leasing ne procure aucune valeur ajoutée par rapport à l’achat d’un équipement au travers d’un crédit : les deux moyens de …nancement sont associés à un même taux d’intérêt, ont un statut …scal similaire et prévoient le même prix de revente de l’actif. Toutefois, dans la pratique, ces conditions ne sont pas toujours satisfaites et il existe plusieurs 2 White Clarke Global Leasing Report (2008).

Pour les grandes entreprises, leur étude révèle que les responsables …nanciers utilisent le leasing comme un instrument pour minimiser le coût après impôt du capital. Pour les petites entreprises, le leasing apparaît comme une opportunité de croissance et de survie. Les petites entreprises ont des di¢ cultés pour accéder au marché du crédit. De ce fait, le leasing facilite le …nancement de la formation de capital …xe. En d’autres termes, les petites entreprises à fort potentiel de croissance ou avec de faibles béné…ces sont plus susceptibles de faire appel à ce mode de …nancement. En conséquence, sans le leasing de nombreux projets n’auraient jamais pu voir le jour. Drakos et Goulas (2008) avancent que l’incertitude d’un investissement pour une entreprise est exacerbée par l’irréversibilité du capital. En permettant la séparation de l’utilisation d’un équipement avec les engagements associés à son acquisition7 , le leasing facilite le désengagement de projets infructueux. Schmitt et Stuyck (2002)8 , Schmitt (2003)9 et Schmitt (2004) ont démontré que le leasing est une activité relativement peu risquée et que les recommandations de Bâle 2 pour le montant des réserves en capital devrait être réduit pour les entreprises de leasing. Au total, le leasing apparaît comme un instrument …nancier sûr. En outre, le fait de louer des biens plutôt que de les vendre peut contribuer à réduire les problèmes environnementaux10 . La pratique du leasing limite la production de déchets et incite à la création d’un schéma d’utilisation du matériel en boucle fermée. Pour certains équipements et certains types de contrats, les fabricants peuvent prendre conscience des problèmes opérationnels, ainsi que des coûts associés à la gestion des produits en …n de vie. Ainsi, ils peuvent redessiner les produits en conséquences a…n de limiter les externalités négatives en …n de vie. En restant dans le circuit commercial, les équipements sont moins susceptibles d’être jetés aux ordures ou stockés quand ils deviennent 6 Lasfer et Lewis ont énuméré trois principales motivations pour la location. D’abord, la location peut réduire les taxes …nancières. Deuxièmement, le leasing pourrait être avantageux …nancièrement pour les entreprises en di¢ culté a…n d’obtenir un accord et l’accès aux équipements, car les bailleurs ont des créances de premier rang sur l’actif. En…n, le leasing peut réduire le coût d’agence parce qu’il ne constitue pas un investissement complet pour le locataire. 7 L ’hétérogénéité du capital et les di¤érents degrés d’irréversibilité associés expliqueraient ainsi les divers recours au leasing par les entreprises. 8 Schmitt et Stuyck ont analysé des contrats de leasing en défaut sur une période de 1976 à 2000 dans six pays d’Europe au sein de douze grandes entreprises. Ils ont constaté que le taux de recouvrement était comparables à celui des obligations de premier rang. 9 L’estimation de la fonction de distribution des pertes et la Value at Risk dans le secteur du leasing révèlent que l’activité présente un risque relativement faible. Voir aussi Pirotte et Vaessen (2008). 10 Voir Fishbein, McGarry et Dillon (2000). xvi INTRODUCTION GÉNÉRALE obsolescents. Malgré le peu d’études sur le sujet, nous devons également souligner que l’intervention des sociétés de leasing crée un attrait supplémentaire pour ce mode de …nancement. Les sociétés de leasing ne sont pas seulement des intermédiaires et leur expertise produit une valeur ajoutée dans la démarche de leasing. Elles sélectionnent le matériel approprié en fonction de sa capacité à améliorer le rendement du locataire et prennent en compte divers facteurs tels que les caractéristiques du matériel, sa durée de vie économique, la …scalité, et la valeur résiduelle (voir infra). Les sociétés de leasing ont aussi des compétences en …nance, en risque de crédit, et en négociation pour l’acquisition d’équipement. D’une manière generale, elles facilitent les échanges entre les fournisseurs d’équipement et les utilisateurs11 . Pour les sociétés de leasing, le risque de perte à la revente à la …n de la durée du contrat, ainsi que la tari…cation, sont fortement impactés par le prix de revente estimé de l’actif. Dans cette thèse, nous étudions un dé… crucial pour le bailleur : le risque de valeur résiduelle. Les trois paramètres essentiels d’un contrat de leasing sont le prix de l’équipement original, la durée du contrat et la valeur résiduelle. Ils déterminent la compétitivité et, en même temps, l’exposition à un risque attaché à la valeur de l’actif. La valeur résiduelle est la valeur estimée de l’actif à la …n du contrat car le bailleur doit estimer la valeur au prix du marché de l’équipement à la …n de la période contractuelle. Ces trois paramètres dé…nissent l’essentiel du niveau de dépréciation (qui peut être compris comme l’écart entre le prix de l’équipement d’origine et la valeur résiduelle) et du montant de loyer payé par le locataire pour utiliser l’équipement. La part de la dépréciation dans le loyer (qui, généralement, en constitue la plus grande partie) peut être calculée par le montant total de dépréciation divisé par le nombre de paiements12 . De plus, plusieurs éléments sont inclus dans 11 Parmi les nombreuses études relatives aux avantages du leasing, nous devons aussi mentionner Kichler et Haiss (2009), qui expliquent la contribution du leasing à la croissance économique des économies d’Europe centrale et orientale, ainsi que la thèse de Brage et Eckerstom (2009), qui comparent les di¤érents avantages du leasing en Suède et au Japon. 12 Par exemple, dans un contrat de leasing automobile avec un prix d’équipement d’origine de 12000 $, une valeur résiduelle de 7200 $ et une période de bail de 24 mois, le paiement mensuel de l’amortissement (à l’exclusion des taux d’intérêt et impôts) est de 200 $ par mois ( 12000 7000 24 ). xvii les paiements e¤ectués par le locataire tout au long du contrat : les intérêts sur l’investissement du bailleur, les frais de service (y compris les coûts d’exploitation, l’assurance, le conseil, les réparations) et les taxes. La …gure A illustre les mécanismes en jeu dans le calcul des paiements d’un contrat de leasing13 . Figure A : La dépréciation dans un contrat de leasing de l’equipement - Valeur residuelle Loyer = ( Prix d’achat ) + Taux d’intérêt + Taxes + Frais de Services. nombre total de paiements Quand la valeur résiduelle augmente, l’écart avec le prix initial de l’équipement diminue et le montant du loyer diminue aussi. Une valeur résiduelle élevée permet au locataire de payer un montant plus bas pour utiliser l’équipement. Le contrat proposé par le bailleur devient plus compétitif. Cependant, ce qui contribue au succès d’une société de leasing peut entraîner des di¢ cultés lorsque les conditions du marché changent. Le bailleur prend le risque de ne pas être en mesure 13 A des …ns de simpli…cation, nous n’avons pas mentionné un quatrième élément : les options de …n de contrat. Di¤érentes options peuvent être disponibles pour le locataire : la période de location peut être prolongée, le contrat peut être renouvelé, les équipements peuvent être rachetés ou rétrocédés. xviii INTRODUCTION GÉNÉRALE de récupérer su¢ samment de capital lors de la revente de l’actif. Il existe un risque de valeur résiduelle. Comme cela est illustré par la …gure B, la courbe de la valeur de marché révèle un gain ou une perte à la revente, en fonction du niveau de valeur résiduelle. Figure B : La valeur marché d’un actif Le bailleur fait ainsi face à un dilemme. Plus la valeur résiduelle est basse, plus le risque de perte à la revente est faible. Mais, en même temps, le loyer augmente et le bailleur perd sa compétitivité. Inversement, plus le risque de valeur résiduelle est élevé et plus le contrat de leasing est compétitif. Nous apportons une perspective académique à la pratique de la gestion du risque de valeur résiduelle. Dans une société de leasing, le département de gestion d’actifs est en charge du risque de valeur résiduelle et estime les prix de revente des équipements en leasing. Au cours des sept dernières années, j’ai travaillé sur l’analyse de la valeur résiduelle au sein de General Electric Capital, une des plus grandes entreprises de leasing dans le monde14 . Grâce à ma position européenne au sein du groupe, j’ai eu la possibilité de rencontrer des analystes de 14 L’actif total de GE Capital Commercial Finance était de plus de 230 milliards de dollars en 2008. xix gestion d’actifs à travers di¤érents pays. J’ai aussi eu un aperçu des pratiques aux États-Unis, en Nouvelle-Zélande, en Australie et au Japon. J’ai vécu une situation qui est partagée par les professionnels dans de nombreux domaines : les équipes de gestion d’actifs reproduisent des méthodes et des processus opérationnels, créés par leurs prédécesseurs, en les améliorant par tâtonnement15 . Il y a une transmission du savoir-faire par l’application d’un minimum de théorie. Plus spéci…quement, peu de travaux académiques16 et très peu de modèles statistiques sont dédiés au risque de valeur résiduelle.

Figure C : Le volume de leasing dans le monde Néanmoins, les analystes de gestion d’actifs n’ont pas attendu la théorie et les apports académiques pour estimer la valeur d’un équipement en …n de période contractuelle. Ils doivent en e¤et proposer un prix pour établir un contrat. Notre objectif général est d’enrichir la littérature sur le sujet et ainsi d’apporter ‘un peu de la théorie à la pratique’18 .

Or le point de vue académique ajoute un contrôle théorique sur les outils et les hypothèses utilisées par les spécialistes. De plus, la position académique fournit une approche libérée de tous préjugés créés par l’appartenance aux métiers du leasing. Une analyse de la valeur résiduelle comporte plusieurs éléments parmi lequels : les caractéristiques techniques de l’actif, la composition du portefeuille d’équipement et la courbe de dépréciation. C’est pourquoi nous pouvons béné…cier de la littérature déjà en usage dans d’autres domaines, comme les modèles économétriques des prix hédonique ou la litterature en macroéconomie. Les sections empiriques de la thèse se concentrent sur les contrats de leasing automobile. L’automobile constitue un vaste marché et permet de collecter de nombreuses informations sur le comportement de dépréciation des actifs.

En revanche, la location longue durée couvre les contrats pour les entreprises qui externalisent leurs besoins en ‡otte de véhicules à une société de leasing. En plus des véhicules nécessaires, la société de leasing fournit généralement des services connexes, comme la maintenance, la gestion du carburant et l’assurance. La thèse se concentre principalement sur la location longue durée. La thèse s’organise en trois chapitres. Dans le premier chapitre, nous étudions la valorisation et le comportement de dépréciation d’un actif : l’automobile. Dans le deuxieme chapitre, nous proposons une nouvelle façon de couvrir le risque de valeur résiduelle. Dans le troisième chapitre, nous étudions la relation entre les marchés du neuf et de l’occasion.

Suite à une discussion sur les prix hédoniques, nous proposons un modèle opérationnel pour le marché de l’automobile d’occasion. Le modèle est appliqué à quatre pays européens (l’Allemagne, l’Espagne, la France et la Grande-Bretagne), et les distributions sont calculées sur deux modèles de véhicules (Audi A4 et Ford Focus) permettant la comparaison des pro…ls de dépréciation et des risques de valeur résiduelle. Le deuxième chapitre propose un modèle statistique pour couvrir le risque de valeur résiduelle en utilisant la technique des copules gaussiens. A la suite d’une discussion sur la problématique du risque de valeur résiduelle et des modèles de risque de crédit existant, un nouveau produit dérivé est proposé et analysé : le Collateralized Residual Values (CRV). Le modèle est appliqué à un portefeuille européen de location longue durée d’automobiles. Nos résultats indiquent que ce produit …nancier est facile à adapter et à mettre en œuvre en fonction des caractéristiques du contrat et du niveau de corrélation.

Les équipes de gestion d’actifs doivent prendre en considération les facteurs macroéconomiques pouvant in‡uencer les prix de revente des actifs. Le dernier chapitre analyse un élément crucial de cette question. Les voitures neuves d’aujourd’hui seront les voitures d’occasion de demain, et l’on suppose une forme de compétition entre le marché du neuf et le marché de l’occasion. C’est pourquoi il existe quelques idées préconçues et de nombreuses théories sur les interactions entre le premier marché et le second marché. Nous proposons de développer la ré‡exion par une analyse macro-économique des marchés automobiles Français, Britanniques et Nord-Américains.

Nos résultats indiquent que les relations entre les di¤érents marchés semblent limitées en France et au Royaume-Uni, alors que le marché Nord-Américain est confronté à un mécanisme dit de ‘Scitovscky’. Dans tous les cas, les relations ne sont pas assez fortes pour expliquer complètement les comportements des marchés. xxii INTRODUCTION GÉNÉRALE General Introduction "(. . . ) the real principle of the irreplaceable empirical research creativity : doing, without knowing exactly what we are doing, gives the opportunity to discover, in what we do, something we did not know." P. Bourdieu, Homo Academicus, Les Editions de Minuit, 1984, p17. The leasing industry appears as a little known area and a great business. The International Accounting Standard for Leases, or IAS1719 , de…nes a lease as "an agreement whereby the lessor conveys to the lessee, in return for a payment or series of payments, the right to use an asset for an agreed period of time". Legislation may be di¤erent across countries, contracts can be adjusted to meet the needs of a customer, and any sort of good can, in theory, be leased ; therefore, the term ‘lease’includes a large variety of contracts. On the whole, a lease is a …nancial instrument for the procurement of an equipment. In a leasing contract, a lessor provides equipment for usage on a de…ned period of time to a lessee for speci…ed payments. The asset leased could be any kind of equipment (i.e. printers, trucks, aircrafts. . . ) used by the lessee for business purposes. The lessor purchases the equipment and has the legal ownership of the asset. To use the equipment the lessee makes periodic payments throughout the contract to the lessor. The entire Global leasing market20 was estimated to be more than $ 633 billion in 2006. Europe and North America accounted for 41% and 38% of the world market. The ‘World 19 All listed companies in the European Union are obliged to adopt the International Standards. The equivalent standard in the USA is FAS 13. 20 White Clarke Global Leasing report (2008). xxiii xxiv GENERAL INTRODUCTION Leasing Yearbook 2009’reported a total global amount of equipment leased to be more than $ 760 billion for 2007. The European leasing associations reported a new leasing volume above e 330 billion and a contribution to …nancing, on average, of 18% of total European investment for 2008. Furthermore, leasing involved more than 16 million cars in Europe21 . Broadly speaking, almost all academic contributions on the leasing subject are related to the comparison of leasing over lending and purchasing. Researches can be divided into three groups. Firstly, some papers analyze tax advantages regarding the choice between leasing and regular debt22 . The second group of academic articles discusses the ‘Leasing Puzzle’. Theories in Finance and Economics suggest that leases and debt are substitutes ; an increase of leasing should lead to a decrease of debt ; moreover, standard …nance theories manage cash ‡ows from lease obligations as an equivalent to cash debt ‡ows. Ang and Peterson (1984) found empirically that lease and debt appear as complements for companies. They argued that greater leasing is associated with greater debt. They could not …nd a conclusive explanation and they called their …nding the unsolved puzzle in Finance or the “Leasing Puzzle”. Following their seminal article, the academic contributions have been numerous to reinvestigate the results23 . The ‘Puzzle’leads to the third area of research covering every article related to the incentives and advantages of leasing. Lasfer and Levis (1998), for instance, rephrased the problem. In theory, leasing provides no added value to the purchase of equipment when a lessee or a purchasing …rm, lend or borrow at the same rate of interest, have a similar tax status and expect the same resale price of the asset at the end of the contract. In practice, however, these conditions are not satis…ed and there are several motives for leasing24 . For large …rms, their study reveals that …nancial managers use leasing as an instrument to minimize the after tax 21 22 Leaseurope Association Website. See Smith and Wakeman (1985), Brick, Fung and Subrahmanyam (1987), Mackie-Mason (1990), Goodacre (2002). 23 See Marston and Harris (1988), Lewis and Schallheim (1992), Krishnan and Moyer (1994), Branson (1995), Beattie, Goodacre and Thomson (1999), Yan (2006). 24 They listed three main motives for leasing : First, leasing can reduce …nancial taxes. Second, it could be advantageous …nancially for distressed companies to get an agreement and access to the equipment because lessors have …rst claims over the asset. Finally, leasing can reduce the agency cost because it does not constitute an investment for the lessee. xxv cost of capital. For small companies, leasing appears as an opportunity for growth or survival. They have di¢ culties to access the debt market and leasing facilitates the …nancing of …xed capital formation. In other words, small companies with potential important growth rates or low pro…ts are more likely to lease. As a consequence, without leasing many projects would not have been undertaken. Drakos and Goulas (2008) mention the uncertainty in entrepreneurship exacerbated by the irreversibility of capital. By allowing the separation of usage to the commitment of equipment ownership25 , leasing facilitates a possible disengagement in unsuccessful projects. Schmitt and Stuyck (2002)26 , Schmitt (2003)27 and Schmitt (2004) demonstrate that leasing is a relatively low risk activity and that Basel 2 requirement should be reduced for leasing contracts. All in all, leasing appears as a safe …nancial instrument ; furthermore, leasing can reduce environmental problems28 . The practice of leasing products, rather than selling them, prevents waste generation and creates a pattern of closed loop material use. For speci…c equipment and leasing contracts, manufacturers become more aware of operating problems and cost management for products at life end. Consequently, they may redesign their products accordingly. Staying in a commercial channel, the equipment is less likely to be stored or discarded when it becomes obsolete. Besides the lack of elements on the subject, we should also highlight that leasing companies’ interventions create additional attractiveness. Leasing companies are not only intermediaries ; their expertise produces a real added value in the leasing process. They select the appropriate equipment based on its ability to improve the leasing cash ‡ow through various parameters like equipment characteristics, economic life of the asset, taxes or residual value risk. Leasing companies have also skills in …nance, credit, equipment acquisition and dealing. All things considered, they facilitate the transactions between equipment suppliers and equipment users29 . 25 26 Capital heterogeneity would explain di¤erent choices of leasing by di¤erent degrees of irreversibility. Schmitt and Stuyck (2002) analyzed defaulting leasing contracts issued from 1976 to 2000 in 6 countries and originated from 12 major European companies and found that the recovery rate of defaulting leasing contracts are comparable to senior secured bonds. 27 The estimation of the probability density function of losses and the standard portfolio credit value at risk (VAR) measures in the leasing industry reveals a relatively low risk activity. See also Pirotte and Vaessen (2008). 28 See Fishbein, McGarry and Dillon (2000). 29 Among the numerous contributions related to the advantages of leasing, we could also mention Kichler and Haiss (2009), showing the support of leasing in economic growth of central and Eastern Europe, as well as the xxvi GENERAL INTRODUCTION For Leasing companies, the risk of loss on sales at the end of the contract term, as well as the pricing, are critically impacted by the forecasted resale price of the asset. In the thesis, we study a crucial challenge for the lessor : the residual value risk. The three key parameters of a leasing contract are the original equipment price, the lease period and the residual value. They drive the competitiveness and, at the same time, a risk on the asset. The lessor has to set the end of contract market value of the equipment and the residual value is a forecasted value of the asset. The three parameters mainly de…ne the level of depreciation (which can be seen as the variance between the original equipment price and the residual value all along the lease period) and the rental amount paid by the lessee to use the equipment. The depreciation part of the lease payment (usually the larger component) can be calculated by the total amount of depreciation divided by the number of periods30 . Additionally, several features are included in the payments made by the lessee during the contract ; depreciation of the asset interests on the lessor investment, servicing charges (including operational costs, insurance, counseling, repairs) and taxes. Figure A illustrates the mechanism involved in the calculation of the lease payments31 . thesis of Brage and Eckerstom (2009), comparing the incentives to lease in Sweden and Japan. 30 For instance, in an automotive lease contract with an original equipment price of $ 12000, a residual value of $ 7200 and a lease period equal to 24 months, the monthly payment of the depreciation (excluding interest rate and taxes) should be $ 200 per month ( 1200024 7000 ). 31 For simpli…cation purpose, we did not mention another key element : the end of term options. At the end of the contract, there are options allowed to the lessee. Lease period can be extended ; lease can be renewed ; the equipment can be bought or returned. xxvii Figure A : Depreciation in a leasing contract Price - Residual Value LeaseRental = ( Original Equipment ) + interestrates + taxes + servicing charges. Lease Period As a result, when the residual value increases, the variance with the original equipment cost decreases, as well as the rental amount. A high residual value creates, for the lessee, an opportunity to pay a lower amount for the usage of the equipment and therefore, for the lessor, better competitiveness. What makes the success of a leasing company can lead to di¢ culties when market conditions change. The lessor faces the risk to not being able to recover su¢ cient capital value from the resale of the asset, the residual value risk. As illustrated by Figure B, the fair market value curve implies a gain on sale, or a loss on sale, depending on the level of residual value. xxviii GENERAL INTRODUCTION Figure B : Fair Market Value of an Asset So the lessor faces a dilemma ; the lower the residual value, the lesser the risk of loss on sale, but the lower the residual value, the higher the rental payment and the worse the competitiveness. Conversely the higher the residual value risk, the better the competitiveness. We bring an academic perspective to the practice of residual value risk management. In a leasing company, the Asset Management department is in charge of the residual value risk and forecasts how much the equipment will be worth at the end of the contract. For the last seven years, I have been working in General Electric Capital Finance, one of the biggest leasing companies in the world32 , on residual value analysis. Thanks to my European position, I meet asset analysts across various countries and I have had some insight from the US, New Zealand, Australia and Japan. I experienced a common situation for professionals in various areas : asset teams reproduce operational processes, created by predecessors, and improved through trial and error33 . There is a transmission of know-how, by applying minimum theory. As a matter of 32 33 Commercial Finance’s assets total was over $230 billion in 2008. For instance the situation is similar in the …nancial derivatives industry. “Option hedging, pricing, and trading (. . . ) is a rich craft with traders learning from traders (or traders copying other traders) and tricks developing under evolution pressures, in a bottom-up manner.” Haug and Taleb (2009). xxix fact, few academic literature34 and few developed models are dedicated to residual value risk. For instance, although the volumes involved are similar (Figure C)35 , structured …nance and its vast growth attracted much more academic research than leasing. Figure C : Volume of equipment leased in the world Nevertheless, asset analysts did not wait for theory and academics to estimate residual values. They have to propose a price in order to set a contract. Analysts are in a position of practice with limited theory36 . As a general purpose, we aim to contribute to the rare literature in the area, and accordingly to bring theory to the practice. The aim of any theory is to model phenomena so that we can better understand and exploit them. The academic view adds a theoretical control on tools and assumptions used by the specialists. Furthermore, it provides an overview free of bias created by the inner position of the asset analyst. A residual value analysis involves several elements including the characteristics of the equipment, the mix of the portfolio, and the depreciation curve. Consequently, we can bene…t from diverse kinds of literature already in use in others area, like hedonic or macroeconomic models. 34 The rare contributions are listed in the second chapter.

Equipment …nancing involves di¤erent areas of expertise : …nance and the industrial sectors where it operates. xxx GENERAL INTRODUCTION The empirical parts of the thesis focus on automotive leasing contracts. By and large, automotive constitutes a huge market providing numerous information. The high level of residual value of cars at the end of the contract, by comparison with other types of equipment, increases the probability of losses and represents a critical challenge for leasing companies. Two kinds of auto lease contracts can be de…ned : short-term auto lease contracts include cars (or trucks) rented to private or professional clients for a relatively short period of time in order to meet their occasional transport needs ; in contrast, long-term auto lease covers contracts for businesses outsourcing their vehicle ‡eet needs to a leasing company. In addition to the necessary cars (or trucks) the leasing company usually provides various related services, like maintenance, fuel management, and insurance. The thesis primarily focuses on long-term auto leasing. The thesis is divided into three chapters. In the …rst chapter, we discuss the valuation and the depreciation of an asset : a car. In the second chapter, we propose a new way to hedge residual value risk. In the third chapter, we study the relation between the new and the used markets. In the …rst chapter, we apply the Hedonic methodology to European auto lease portfolios, in order to estimate the resale price distribution. The Hedonic approach estimates the price of a good through the valuation of its attributes. Following a discussion on Hedonic prices, we propose an operational model for the automobile resale market. The model is applied to four European countries (France, Germany, Spain and Great Britain), and distributions are calculated on two vehicle versions (Audi A4 and Ford Focus) allowing a comparison of market depreciation patterns and residual value risks. The second chapter proposes a model to hedge residual value risk using the Gaussian copula methodology. After discussing residual value risk and credit risk models, a new derivative product is introduced and analyzed ; the Collateralized Residual Value (CRV). The model is applied to a European auto lease portfolio of Operating Lease contracts pertaining to a major company. Our results indicate that the …nancial product is easy to customize, and to implement through the contract characteristics and the level of correlation between the assets of the portfolio. The second chapter is intended for people within the leasing industry interested by an innovative …nancial product, as well as people from the …nancial market concerned by xxxi leasing risk opportunities. Asset Management teams have to take into consideration macroeconomic factors impacting the asset resale prices in the used market. The last chapter analyzes a crucial element of the problem. The new cars of today are used cars of tomorrow and a competition is assumed between new and used markets. There are numerous, pre-conceived ideas and academic theories regarding the interactions between primary and secondary markets. We propose to go further through a macroeconomic analysis of the French, the British and the US car markets. The di¤erent concepts are listed and statistically evaluated. What are the interactions between the new and the second-hand car markets ? Can we use the interactions to estimate the car prices of tomorrow ? Our results indicate that the relations appear limited for France and the UK, whereas the US market faces a Scitovscky mechanism. Furthermore, they illustrate that the interrelations are not strong enough to fully explain and forecast market patterns. xxxii GENERAL INTRODUCTION Chapitre 1 The European used-car market at a glance Hedonic resale price valuation in automotive leasing industry1 1 This chapter has been published in Economics Bulletin : Prado Sylvain M. (2009) The European used-car market at a glance : Hedonic resale price valuation in automotive leasing industry. Economics Bulletin, Vol. 29 No.3 pp. 2086-2099. 1 2 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE 1.1 Introduction In the auto lease industry, a large part of the rent paid by the customer during a life contract is the di¤erence between the list price and the residual value. The leasing company makes or losses money depending on whether it accurately predicts the value of the asset at the end of the contract (fair market value). If residual values are forecasted to be higher than what the asset is actually worth at lease-end, then there will be a loss. At the opposite, if residual values are forecasted to be lower, then there will be a gain on resale. The estimated resale price of the car at the end of the contract term appears as a key component for the pricing, the risk of losses and the reserve calculation2 . Akerlof (1970) explained why used car valuation is so much lower than new car valuation. The automotive resale market is a¤ected by something called the ’lemon e¤ect’. A used car has the probability to be of a good quality or a bad one (i.e. lemon), and the uncertainty about quality implies a price adjustment3 . The Akerlof theory helps to understand the large variance of prices between new and used markets, but it does not propose a methodology to calculate car depreciation. Another way of looking at it is the Hedonic approach. The Hedonic theory provides solutions and estimates price-quality relation through a detailed calculation. A Hedonic model has been originally proposed by Waugh (1928) on vegetable products and by Court (1939) in the automobile industry. Hedonic models have been applied to a lot of commodities (mainly real estate and automobile but also fruits or vine4 ). The automobile market itself has had di¤erent applications (quality corrected price index5 , demand for fuel e¢ ciency, valuation of environmen- 2 This article is part of a general study on resale market hedging (Prado, 2008). We aim to estimate the distribution of the resale price in order to include the depreciation behavior in a derivative product. 3 In the resale market, there is an asymetry of information ; the car owner has a better knowlegde of the probability of bad lemons. If Second hand vehicles were valued like as new vehicles, then it would attract lemons (lemons’sellers would have the opportunity to sale their vehicles and buy a new one on the new vehicle market) and it would create an arbitraging opportunity. Akerlof used the automotive market as a best illustration and extended his idea to other markets (the cost of deshonesty...). 4 Combris, Lecoq and Visser (1997). 5 Cowling and Cubbin (1972) and Van Dalen and Bode (2004). 1.1. INTRODUCTION 3 tal and safety demand6 , test of the Akerlof e¤ect7 , behavior of the automobile market through price quality and competition8 ...). The main point underlying this paper is to apply the Hedonic methodology to estimate the resale price distribution of cars in a leasing perspective. The …rst chapter is intended for people within the leasing industry intersted by residual value risk management, as well as academics concerned by a comparison of European markets. We propose a methodology for operational applications to estimate the distribution of resale price. To this end, we apply a Hedonic model (a method of estimating value through constituent characteristics of the asset) on historical information from a major leasing company9 . Further to this, we estimate a value according to vehicle characteristics and country singularities. Resale price distributions of two vehicles (Ford focus C-max, Audi A4) are calculated in various European markets (France, Germany, Spain and Great Britain). The chapter is organized as follows. Section 2 discusses the Hedonic theory underlying our model. In section 3 some meaningful characteristics of the model are exposed. Section 4 presents our approach. Section 5 estimates the distributions and analyzes the results, …nally. Section 6 concludes. 6 Atkinson and Halvorsen (1990). Couton, Gardes, and Thepaut (1995). 8 Cowling and Cubbin (1971) and Cubbin (1975). 9 In Europe, statistics on resale prices are not as abundant as in …nancial markets and leasing companies 7 often have to use internal data to forecast the market value. External information is usually not available on line, costly and time consuming to collect. Morevover, there is a non homogeneous information and format by country. Therefore we use the internal resale information (GE resale data warehouse). 4 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE 1.2 The Hedonic theory underlies our model The section discusses the Hedonic model approach, identi…cation issues and automotive assets speci…cities. 1.2.1 Goods attributes constitute the Hedonic theory. To explain consumer behavior, Lancaster (1966) assumes that consumers get utility from goods attributes10 . Assuming that a car is the only good involved in the activity consumption of driving, it produces a …xed vector of attributes and the level of activity is a scalar associated with the vector (the relationship could be linear). The driver chooses a combination to maximize his utility function according to the characteristics of the goods under a constraint budget. Inspired by Lancaster (1966), Pickering et al(1973) added an empirical perspective to the approach by conducting a survey in the UK. Following their results, they de…ned …ve groups of commodities (utilities, luxuries, leisure goods, central heating and automotive) and identi…ed eleven characteristics as signi…cant discriminators between groups. The principal attributes desired by car buyers were comfort, durability, economical, manoeuvrability, performance safety and style. They acknowledged that products and attributes may change groups through time because of product life cycle, di¤erent tastes between consumers, the growth of the market penetration (i.e. luxuries becoming utilities), complementarity or substitutability of goods11 . They also …gured out that it could be relevant sometime to disaggregate a group (i.e. cars by makes). The Hedonic model assumes that goods are valued for their utility-bearing attributes or characteristics. In 1974, Rosen12 developed the framework of Hedonic models. The theory describes cars by n measurable characteristics (oil consumption, car size, power, technology...) and a vector Z(= z1 ; z2 ; :::; zn ) with zi measuring the amount of the ith characteristics. The exis10 Similar attributes or characteristics could be shared by di¤erent goods. Usually goods have several charac- teristics, and a combination of goods may have attributes di¤erent to goods used separately. 11 We could also add the technology obsolescence to the list. 12 See Appendix A1. 1.2. THE HEDONIC THEORY UNDERLIES OUR MODEL 5 tence of product di¤erentiation implies that a wide variety of alternative packages, completely described by numerical value of z, are available. Buyers and sellers locate in a spatial equilibrium. On one side, the consumption decision is made by a maximization of utility. On the other side, the production decision is made by minimizing factor costs subject to a joint production function constraint relating to the number of units and factors of production. A price p(z) = p(z1 ; z2 ; :::; zn ) is de…ned at each point on the plane. Both consumers and producers are guided by prices through packages of characteristics bought and sold. Observations of p(z) represent a joint envelope of a family of value functions and another family of o¤er functions. At equilibrium, buyer and seller are perfectly matched when their demand and o¤er functions meet at eye level. The approach consists in estimating the following model : P i(z) = F i(zi ; :::; zn ; y1 ) (demand) P i(z) = Gi(zi ; :::; zn ; y2 ) (supply) P i(z) is the implicit market price for attribute zi , y1 and y2 are vector of exogenous demand shift variables and a vector of exogenous supply shift variables, respectively. At equilibrium, market quantity demanded for products with characteristics z, (Qd (zi )) is equal to market quantity supplied with those attributes (Qs (zi )). A P (z) function has to be found to make this equality possible. Unfortunately, di¤erential equations for setting (Qd (zi )) = (Qs (zi )) are not linear in most cases and closed solution are not always possible. 1.2.2 An identi…cation problem appears in Hedonic models. There are identi…cation problems in the Rosen model : if p(z) is non linear, it may not be possible to …nd closed solutions. A lot of conditions must be imposed and partial di¤erential equations must be solved when there is more than one characteristic. Rosen believed that the form of the Hedonic function is an empirical matter and developed an empirical methodology to estimate demand and supply parameters (if no explicit solution for the Hedonic price function is available). Rosen solved the "garden variety identi…cation problem" by simultaneous identi- 6 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE …cation methods like 2SLS : p(z) is estimated by regressing all observed di¤erentiated product prices p on all their characteristics, z, using the best adaptable function. The estimated prices are then included in the complete formula as endogenous variables. Later, Brown and Rosen (1982) showed that this technique is not always possible (it still requires prior restriction on functional form)13 . But Bartik (1987) argued that the econometric problem of estimating Hedonic demand parameters is not a standard identi…cation problem caused by demand-supply interactions : because a consumer decision cannot a¤ect an Hedonic function, it does not a¤ect the supplier. He pointed out another identi…cation problem : the Hedonic price function is not linear and the consumer can endogenously choose both quantities and marginal prices. Formulated through a characteristic bid equation14 it highlights the impact of consumer traits. Let @p (Zi ) @zj be the estimated Hedonic marginal price of characteristics zj = Wij , where Zi denotes a vector of observed characteristics of the product and Wij a consumer marginal bid for zj : @p (Zi ) @zj = b0 + b1 Zi +b2 Xi +bD0i +eij . Xi is consumer expenditure on commodities others than Z. D0i is a vector of observed demander traits a¤ecting the marginal bid. eij is a disturbance term. It becomes @p (Zi ) @zj = b0 + b1 Zi +b2 Xi +bD0i + Dui +rij . Dui is an unobserved taste component form. rij is a random component and rij + Dui = eij . Therefore Zi and Xi are correlated with unobserved tastes in the residual, leading to biased results (equivalent to di¤erent population of consumers). In Bartik’s article, the identi…cation problem is caused by the endogeneity of both prices and quantities when households face a nonlinear budget constraint (the distribution of income 13 Ekeland, Heckman and Nesheim (2004) reconsidered the identi…cation and estimation of the hedonic model. They show that most of empirical studies are based on arbitrary linearisation. Two new estimations procedures are proposed : a non parametric transformation method and instrumental variables in a general nonlinear setting. 14 See Appendix A1. 1.2. THE HEDONIC THEORY UNDERLIES OUR MODEL 7 follows no simple law through its range making it di¢ cult to specify the problem entirely). An instrumental variable solution is suggested and applied (household example with addition of budget constraint). The implicit market price is estimated by regressing all observed di¤erentiated product prices p on all their characteristics by group of modality of Dui 15 . We follow on the Bartik critic in our analysis and propose a solution to manage the unobserved taste issue in Section 3. 1.2.3 Used cars are durable commodities. Berndt (1983) provided general frameworks on Hedonic prices for durable goods. Assuming that the asset price of the nth capital good of vintage at time t is equal to the present value of its future services, we have : s=T n P qn;t; = s=0 s 1 1+r Vn;t+s; +s where Tn is the life time of the asset, r the interest rate, Vn;t; the value of the asset at time of the ‡ow of services of the nth capital good of vintage . Berndt demonstrated that the Hedonic price equation can be expressed in terms of service prices in a single equation16 . This concept has been used originally in the second-hand automobile market analysis by Akerman (1973), who produced one of the …rst study on the rapid used car falling prices. The price of an automobile is evaluated as the discounted present value of its remaining services. The Akerman model included a Hedonic price, a repair cost, a service function and an expected gain on resale estimation. Akerman used a single equation and a regression to estimate the Hedonic price17 . Ho¤er and Pratt (1990), inspired by Akerman approach (the price of a resold vehicle as an implicit rental cost of holding a s year old automobile, including also automotive price less market price of interest) proposed a simpler model. A single equation, where depreciation declines with age at constant exponential rate, includes technological obsolescence, di¤erential repair record and fuel e¢ ciency as shift variables. The depreciated value (s; t) of an s-year old machine in year t is 15 Bartick made an adjustment by group of cities. See Appendix A2. 17 See Appendix A3. 16 8 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE ln( (s; t)) = A b1 s + b2 tech + b3 maint + b4 EP A: tech = 0 if the vehicle is not discontinued. maint = 1 if the maintenance expenses are greater than average and EP A is a fuel e¢ ciency indicator. All along the referenced studies, methodology moved from a remaining service approach to a Hedonic model including essentially the vehicle characteristics (physical or not). We acknowledge the "remaining service approach", however we believe that vehicle characteristics contain most of the information. As a consequence, we adjust the resale price from in‡ation and we set a statistical model mainly through variables related to the vehicle characteristics. 1.3 Some characteristics of the model are discussed. The model construction brings comments and discussions : The used market is (i)demand oriented and (ii)correlated with fuel price ; (iii)Multicollinearity is a critical issue in Hedonic calculation ; (iv)We have to choose a functional form, and (v)Heteroscedasticity impacts the model speci…cation. 1.3.1 Coe¢ cients interpretation depends on used market substitution to new market. Berndt (1983) pointed out an argument against the Rosen identi…cation problem for the used market : under speci…c conditions, equation parameters can be directly interpreted as re‡ecting demand (rather than cost or supply) and there is no identi…cation problem. If the supply curves of products are perfectly inelastic, then the market demand and supply curves would intersect at di¤erent levels of each combination of characteristics. The structure combination would be determined by the demand. The di¤erence of price level among products could be interpreted unambiguously as providing implicit measures of consumers’ evaluation of the characteristic combinations. So coe¢ cients of the equation are well identi…ed, as well as estimates of the demand function parameters. Because the total quantities are …xed (assuming that there is 1.3. SOME CHARACTERISTICS OF THE MODEL ARE DISCUSSED. 9 a non signi…cant link with new market), the equation only re‡ects demand in the used car market. Hartman (1987) results validate that an application to the resale market avoids the identi…cation problem. If the supply of the attributes embodied into used cars is almost perfectly inelastic, he states that simultaneity should not pose a problem in recovering Hedonic demand and supply parameters in new product market. If the simultaneity is important, di¤erent assumptions about quantity of each make and model sold should generate di¤erent parameter estimates. Therefore the only question is : are the parameters statistically and economically signi…cant ? In his analysis, the resale value calculation was very robust to alternative sales assumptions. Hartman applied a single equation model18 to estimate the e¤ect of product recalls on resale prices and …rm valuation. Two main conclusions can be stated : All referenced automotive studies use single equation techniques, and remarketing professionals usually believe in a substitution relation for young resale automotive market only which is a situation where demand and supply characteristics are quite similar. Therefore we apply a single equation and we exclude short term duration (less than 12 months age) vehicles. 1.3.2 Others products interact with price. De…ning a framework on the demand analysis, Berndt (1983) discussed the input pricedependent quality adjustment case : the quality of a good (i.e. fuel e¢ ciency) is dependent on the quantity (or price) of another good (i.e fuel price). Berndt states that we could test the dependent19 (or independent) price hypothesis using classical testing procedures (i.e. economical and statistical signi…cance of fuel price on auto price). Fuel price has a signi…cant part in the total cost of automobile usage, and then monthly fuel price constitutes our model. 18 19 See Appendix A4. See Appendix A5. 10 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE 1.3.3 Multicollinearity is a main issue in Hedonic models. The econometrician walks between the two following risks while he selects the relevant variables for an Hedonic estimation : correlated explanatory variables and trickle down hypothesis. In the automotive area, physical characteristics are often correlated (i.e. four wheels correlated to fuel capacities). According to the Gauss Markov theorem, OLS has the smallest variance. However, if explanatory variables are correlated, then small change in the data produces wrong sign, implausible magnitude and wide swings in parameter estimates 20 . As a consequence, pa- rameter correlations present a major issue for forecast applications. The simplest solution is to exclude variables at risk (i.e all variables related to the engine power, number of cylinders, kilowatt, fuel consumption, fuel capacity...) in the case of non economical signi…cance21 . Triplett (1969) highlights another problem. Because a small amount of variables is able to explain most of the variance (i.e. the weight of the vehicle correlated with engine power and price), there are some risk of biases in the Hedonic model and a substantial number of innovations are missed throughout this ’trickle down’hypothesis. Therefore, the selected parameters of our model cover four axes of depreciation e¤ects : the level of usage, the original equipment cost, the market interactions and the pure physical characteristics of the vehicle. 1.3.4 Which functional form ? Rosen (1974) states that the functional form is an empirical matter. In the same logic, Grilitch and Otha (1976) choose a semilogarithmic form for their regression because ’it provided a good …t of the data’. Most of the literature suggests the log form, others studies apply the 20 But it also produces instability of coe¢ cient and higher standard errors, R2 quite high, coe¢ cient with high standard error and low signi…cance levels (even if signi…cant). See Greene (2003) chapter 4 p57. 21 An advanced solution is the ridge regression estimator or principal component methodology. The problem is that we lost visibility on coe¢ cients meaning. 1.3. SOME CHARACTERISTICS OF THE MODEL ARE DISCUSSED. 11 log-log form22 , and the Box Cox test23 has also been used to compare several functional forms. The Hedonic functional form problem constitutes a great discussion but it is not the main purpose of the chapter. We followed the Grilitch and Otha position (1976) (’a good …t of the data’) and empirical results lead us to the linear form of Cowling and Cubbin (1972). Their linear model includes multiple physical variables like horse power and length and to allow approximation to a non linear form, square transformation, cubic transformation and log transformation were applied to exogenous variables. Interactions terms were also included. 1.3.5 Unobserved tastes create heteroscedasticity. As previously mentioned in Bartik’s critics24 , because the choice for the studied commodities quality and other commodities is correlated with unobserved tastes in the residuals, then an heteroscedasticity issue appears. If residuals from the economic relation do not have constant variance, the model is not biased but the variance increases. Bartik states that any variable that exogenously shifts the budget constraint of the buyer will be an appropriate instrument : the budget constraint shift is correlated with the buyer choice of car attributes and the choice of other products yet uncorrelated with unobserved tastes. We follow Bartik’s approach including the index of industrial production25 as a proxy of the economic situation of the buyer (we propose a temporal budget constraint shifter). Because most of buyers are professionals impacted by a market seasonality, we include a seasonality variable on a quarterly basis. Finally, in order to manage unobserved characteristics (i.e. brand name perception and reputation...), we also insert a manufacturer e¤ect 26 . 22 See Hogarty (1975). See Atkinson and Halvorsen (1990), Van Dalen and Bode (2004). 24 See Section 1.2.2. 25 Excluding energy and construction. 26 We do not work with a model car type level, because our goal is to apply a methodology ‡exible enough 23 to include new cars and non exhaustive data. Moreover, our model does not include the life cycle of vehicles (’honey moon’e¤ect for new models...) because of the di¢ culty to collect and to standardize the information. In the list of unobserved characteristics, there is also the remarketing performance. The value could be impacted by the remarketing team in charge of the resale process. Finally, we do not include macroeconomic impacts 12 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE 1.4 We use the Hedonic model to estimate the distribution of resale price. We apply the straightforward regression approach of Otha and Grilitch (1976). Removing the impact of uncertain variables and using the classical OLS properties, resale price distributions are calculated. 1.4.1 Ohta and Griliches have an empirical approach. Regarding theoretical issues (including the one discussed in Sections 2 and 3), Ohta and Griliches state that Hedonic model usage ’has an air of "measurement without theory", but one should remember the limited aspirations of the Hedonic approach and not confuse it with attempts to provide a complete structural explanation of the events in a particular market’27 . They exposed a strong empirical criterion for hypothesis testing28 . They included a make e¤ect as a proxy of unmeasured characteristics. A real e¤ect linked to unmeasured physical characteristics and a putative one (linked to prestige, service availability...) constitute the make e¤ect. In their model, the price of model k of make i and age s at time t is P Pk;i;t;s = f ct(Mi ; Pt ; Ds ; e aij xkivj ) with Mi the e¤ect of the ith make, Pt the pure Hedonic price index at time t, Ds the e¤ect of age s (depreciation). aij are parameters re‡ecting the imputed price of physical characteristic (which need a proper analysis). Therefore unobserved e¤ects mentioned above constitute the random variable of the statistical model. 27 Ohta and Griliches (1976) p326. 28 "The rejection or acceptance of an hypothesis should depend on the researcher’s interests and his loss function"(p 339). Grilitch and Otha put in perspective the statistical and economic signi…cance. Instead of following a formal Fisher test, they use the di¤erence in the standard errors of the unconstrained and constrained regressions as a relevant measure of the price-explanatory power of a particular model. They do not reject null hypothesis if di¤erences between the standard errors of the unconstrained and constrained regressions are less than or equal to 0:01. 1.4. WE USE THE HEDONIC MODEL TO ESTIMATE THE DISTRIBUTION OF RESALE PRICE.13 j at time t. xkivj is the level of the physical characteristic j embodied in model k of make i and vintage v (v = t s). They applied their models on new and used cars and tested di¤erent hypotheses29 (i.e geometric depreciation held separately from makers). Otha and Grilitch approach is now a standard. As a consequence, Yerger (1995) used this method to discuss an article written by Ho¤er and Pratt (1990) which was inspired by Akerman approach30 . Following these authors, our approach is mainly empirical. We select the model structure that best …ts to reality and choose exogenous variables with a statistical and economic signi…cance. 1.4.2 Statistical models are slightly di¤erent by country. Our analysis includes four countries (France, Germany, Spain, Great Britain) and we de…ne a model for each of them31 . The real resale price is explained by a …rst group of variables indicating the level of usage : age and mileage are in logarithm due to the well known non linearity property of car depreciation. An indicator of usage intensity, the mileage per month, is also included and signi…cant. The second group of variables is related to the list price. A cubicle variable of list price is added (high initial price increase devaluation). The make e¤ect is introduced through a dummy variable of manufacturer multiplied by the list price. Variables bringing market information contitute the third group : the diesel pump price, the industrial production index and the quarter sale date. The last group includes pure physical characteristics that are slightly di¤erent from a country to another (average fuel consumption, body type, number of seats, engine power, number of cylinders, automatic transmission, number of doors). 29 Their results on the US market are worth to mention : no gains to move to performance variables (so we can only use the vehicle characteristics) ; geometric depreciation is an adequate approximation but it is not constant accross time and manufacturers ; New and used car market can be analysed jointly. Unfortunately, because of the rise of fuel cost (1973) they aknowledged that their analysis was already obsolete. 30 See Appendix A6. 31 See models details in Appendix B. 14 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE 1.4.3 We estimate the distribution of resale price. We wish to calculate the distribution of y0 (the resale price) for a regressor vector x0 (group of variables explaining the resale price). The usual regression formula is y0 = a0 b0 x0 . X and y0 denote the full data matrices. b0 is the coe¢ cient vector. We assume32 that y0 follows a normal distribution33 equal to N (xT0 b0 + e; s2 [1 + xT0 (X T X) 1 x0 ]). The con…dence interval is calculated with xT0 b0 1.4.4 t=2(n p 1) p M SE[1 + xT0 (X T X) 1 x0 ]1=2 : An adjustment removes uncertain variables e¤ects. All the exogenous variable values are known with certainty34 , except the fuel pump price and the production distribution index. We aim to remove the product interaction e¤ect (Dp) and the temporal budget constraint (Ip) in order to focus on the vehicle valuation. Assuming that the diesel price and the production price follow a normal distribution, we calculate the mean and the variance from 2004 to 2008 and we estimate a risk neutral distribution of the resale price. The unconditional resale price distribution of xT0 be0 can be solved as N[ 1 R 1 R m(x0 =Dp; Ip) g(Dp) j(Ip) dDp dIp; 1 1 32 1 R 1 R n(x0 =Dp; Ip) g(Dp) j(Ip) dDp dIp] 1 1 Data are composed of subgroups by models, age, mileage and physical vehicle characteristics. Normality hypothesis test are possible on subgroups with a signi…cant amount of data. For models with same age and mileage, H0 is not rejected. The test of normality on the two analyzed vehicles (Ford focus and the Audi A4) is not rejected. 33 See Appendix A7. 34 We limit our analysis to …xed contract with no purchase option and no rewrite, therefore age, mileage and sale dates are known with certainty. 1.5. WE APPLY THE METHODOLOGY TO FOUR EUROPEAN COUNTRIES. 15 Where m() = xT0 b0 + e and n() = s2 [1 + xT0 (X T X) 1 x0 ]. g() and j() are the probability density of the fuel pump price and the production distribution index. The integrals are calculated with numerical integration. 1.5 We apply the methodology to four European countries. Models by country, regression results and graphical illustrations, through two vehicle versions, provide an insight of European markets. 1.5.1 Models are created according to the information usually available in the leasing industry. In order to quantify the Hedonic price, we apply the model to four European markets (France, Germany, Spain, and Great Britain35 ) using internal sales data from January 1st 2004 to December 31st 2008 of a major leasing company. Statistics are based on random samples of cars sold in various channels (auction, dealers, private sellers, etc). Vehicle age samples range from 1 to 10 years, and have mileage ranging from 1,000 to 400,000 km. As expected for leasing companies resale statistics, a concentration of vehicles with high mileage and short age spans (concentration on 24, 36 and 48 months of age with a mileage between 80000 km and 120000 km) constitutes a large part of our sample. All monetary values (sales prices, diesel prices) are adjusted according to the in‡ation. We aim to create a tool allowing a leasing company to catch 35 Great Britain has a sterling pound currency and very limited cross bordering sales with others european countries because of the right hand side weel of the car. Therefore, GB statistics add an original perspective of european markets analysis. 16 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE all the available Hedonic information of the car activity from it’s historical sales. According to the company position in markets, the amount of data is signi…cantly di¤erent by country but su¢ cient for calculation (Fr : 112,875 units, Ger : 7,398 units, Sp : 14,674 units ; Gb : 33,506 units). Contrary to some referenced studies applying the Hedonic model to the car market, we do not limit our analysis to a segment or version of cars. As a consequence, the explained variance (R2 ) is slightly lower (and even more to applied studies on the much more stable new car market). To estimate the manufacturer e¤ect, statistics include several manufacturer names (Fr : 9, Ger : 4, Sp : 6, Gb : 8) by country. 1.5.2 The regression provides a Hedonic price assessment of the European markets. All variables have a signi…cant economic value36 . The explained variances of the OLS regressions are between 0.75 and 0.8. Characteristics adding quality to the car (engine power, number of seats, etc) as well as the industrial production index (as a proxy of budget variation) have a positive sign. According to the Hedonic theory, the price of fuel is an additional cost of the driving activity and has therefore a negative e¤ect. The variables of age, mileage and usage intensity (mileage per month) reduce the resale price, there are parameters correlated to obsolescence and wear. A slight seasonal e¤ect exists in all markets. The well known and better valuations of German manufactured cars (positive make e¤ect) are veri…ed in all countries. 1.5.3 The analysis on Ford focus and Audi A4 give additional informations. France, Germany and Spain share the same currency (Euro) and results estimate the resale price distribution of a vehicle, according to the amount of information available from historical sales. The samples of the four countries have two manufacturers in common : Audi and Ford. We choose the characteristics of the Ford Focus (C-max 1800 TDCI 115 Ghia 5P) and Audi 36 See models results in Appendix C. An indicator of automatic transmission was tested and statistically signi…cant for France. Because the coe¢ cient sign was negative, we removed it. 1.5. WE APPLY THE METHODOLOGY TO FOUR EUROPEAN COUNTRIES. 17 A4 (1.9 Tdi 130 Pack 4P) as a basis to compare the four markets. The information provided by the model could be summarized by two elements. On one hand, a higher valuation of car at the end of the contract reveals better opportunities for leasing business. On the other hand, a higher volatility implies uncertainty on the resale price, and therefore a higher risk of loss on sale. Bucket results : A …rst analysis approach37 on the bucket of a 36 month age group, and 90000 kilometers emphasizes three points. First, the Audi A4 has a better valuation than the Ford Focus in every country. As mentioned previously, German cars bene…t from a ’positive make e¤ect’; they are objects of prestige and share a reputation of good quality cars. Secondly, the high level of standard deviation in all markets reveals a huge volatility. Acknowledging that the second hand market is not as liquid as a …nancial market, it illustrates that a car, as an asset in a balance sheet of a company, constitutes a signi…cant risk. Thirdly, in Germany, cars get a better valuation. A high resale price constitutes a good element for a leasing business ; however the German market also has a higher standard deviation, and therefore a higher risk of loss on sales. Graphical results : The graphics of distribution through age and mileage give an additional perspective of the depreciation38 . The variance is not economically di¤erent when we modify age and mileage parameters (whatever the currency, the age and the mileage, the standard deviation does not exceed two Euros). Age and Mileage do not increase the volatility. Regarding average depreciation, German vehicles are highly correlated with mileage, but Spanish cars are not. Surprisingly, the graphical analysis of age impact on vehicles, reveals that British cars are heavily impacted by the level of usage (kilometer per month variable coe¢ cient) and as a consequence, 12 month age vehicles have a resale price equivalent to 24 age month vehicles. The last two points indicate that Hedonic valuations are signi…cantly di¤erent by country. European markets are not homogeneous, and residual value distributions are always singular. On a business perspective, leasing contracts would be impacted by country speci…cities. 37 38 See Appendix D. See Appendix E. 18 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE 1.6 Conclusion and extensions The Hedonic theory has been widely used for the automotive market analysis. We discuss and propose an application to second-hand vehicles in the leasing industry, where the residual value is a critical parameter (residual value risk). The model is based on attributes in order to estimate the resale price distribution. A product interaction e¤ect (fuel price), and a temporal budget shifter (industrial production index) are also included. The methodology applied to four European countries provides a perspective of the automotive resale markets. Focusing on the pattern of depreciation of two vehicles (Ford Focus and Audi A4), the approach illustrates the di¤erent levels of probability of losses according to the resale information available by a leasing company. The approach also allows the comparison of market opportunities, through pricing analysis and risk. Our study can be extended in several ways. The leasing industry includes all types of equipment and the application of the Hedonic valuation would be ‡exible enough to be extended to assets other than automotive. Moreover, our analysis could also be extended to contracts with a purchase option or a rewrite option on age and mileage (i.e. customers can choose to extend or interrupt their contract(s)). Two other elements in the area of residual value risk should be included to complete the analysis : the vehicle life cycle impact and the macroeconomic impact (the general market depreciation). The macroeconomic element would need a more thorough study. 1.7. APPENDIX 1.7 1.7.1 19 Appendix Appendix A : Methodological aspects. A 1 : In Rosen Hedonic framework, we can de…ne the marginal price on a characteristic level. For any vector of observed characteristics Z (of the car), the Hedonic marginal price for a characteristic z (i.e. fuel consumption) is an estimate of both the marginal bid for z of the household purchasing Z and the marginal o¤er for z of the …rm producing z. Linear version of these marginal bid and marginal o¤er function are de…ned through two equations : Estimated Hedonic marginal price of characteristics p (Zi ) zj = Wij consumer marginal bid for zj = B0 + B1 Zi (vector of observed characteristics of the product) +B2 Xt (consumer expenditure on commodities others than Z) +B2 D0i (vector of observed demander traits a¤ecting the marginal bid) +eij . p (Zi ) zj = Gij …rm marginal o¤er price for zj = Ao + A1 Zt + A2 S0i (vector of observed supplier traits a¤ecting the marginal o¤er) +uij :uij and eij are disturbance terms. A 2 : Berndt de…nes general framework on durables commodities in term of service price. He demonstrates that in the case of the input price-dependant quality adjustment ("variable repackaging hypothesis") the Hedonic price equation can be expressed in term of service price as : ln un;t; = lnpn;t + ln h0n (zn1 ; zn2 ; :::; Znk ; pn 1 ) + lnDn; : With un;t; the resulting asset price, lnpn;t is the quality adjusted "base" price index of the nth capital good at time t, Dn; is a depreciation index varying only with the age of the asset. hn is the quality aggregation function that link the quality bn to the physical characteristics zn . b0n = hn 0(zn1 ; zn2 ; :::; znk ) Tn P s=0 1 s ( 1+r ) dn;s : dn;s is the deterioration of the service over time. The intercept is the quality adjusted service price. A 3 : Akerman model estimates used car value.The price of an Automobile of a given age, K, can be expressed as the discounted present value of its remaining services : 20 CHAPITRE 1. THE EUROPEAN USED-CAR MARKET AT A GLANCE P (K) = RD K S(X)e r(X K) dX with K present age of car, D age of scrappage, X age, r discount rate(assumed constant), S(X) value of services provided by a car of age X, P (K) price of a car of age K. An Hedonic price, repair cost, service function and expected gain on resale estimation are components of the model. Akerman use a single equation and a regression to estimate the Hedonic price : logA(v; m) = C + E(v; m) + C(v; M ) + W (v; M ) + L(v; M ) + H(v; M ) With A(v; m)=new car list price including federal tax and handling and transportation charges. E(v; m)=1 if car has height cylinders. C(v; M )=1 if compact. W (v; M ), L(v; M ) and H(v; M ) are weight, length and horse power. v is model year and m is the model. A 4 : Hartman Equation inspired by Grilitch and Otha equation : LogP kit = Bo + B1 M Ki + B2 M Dk + B3 AGEs + B4 jAkij + B5j Rjk P kit is the resale price in period t for a car of make i and model k. MKi and M Dk are dummy variables indication Make and model. Age is the age of the car in t. Akij is the level of attribute j embodied in model k and make i. Rjk summarize the car recalls history indicating cumulative recalls of type j for model k. A 5 : Berndt de…nes a general framework on commodities. X(= x1 ; x2 ; :::xn ) a vector of commodity, B(= b1 ; b2 ; :::; bn )a vector of qualities for each commodity, Z(= z1 ; z2 ; :::; zi ; zn ) a vector of physical characteristics for each commodity and P (= p1 ; p2 ; :::; pn ) a vector of price for each commodity. Moreover we have an utility function u = F (x; b) and Bn = Hn (Z). As a result, we have xn = f (u; x1 ; x2 ; :::; xn 1 ; bn ) For a new quality level from bn0 to bn1 under the assumption of a log-log form ; 1.7. APPENDIX 21 In the case called the "simple packaging hypothesis" (or input price-independant quality adjustment), bn is only dependant of zi , we have a quality function bi = hi (zi ) ; xn must be equalized at the margin : pn0 pn0 = pn1 pn1 = pn where pn is a base price constant re‡ecting the price of the standardized unit. Through a log transformation of 1), then lnpn1 = lnpn0 + lnhn1 (zn1 ) and an assumption of k P bnk ln zn1;k : log-log form of the quality conversion function lnhn1 (zn ) = k=1 lnpn1 = lnpn + k P bnk ln zn1;k where bnk are the coe¢ cient on the k th characteristics of the k=1 nth commodity. Using this framework we are now able to calculate a price according to the physical characteristics of a commodity. In the case called the "variable packaging hypothesis" (or input price-dependant quality adjustment), for instance if bn is dependant of xn 1 as well ; bn = hn (xn 1; zn ) : lnpn (bn ) = lnp0n + lnhn (pn 1 ; zn ) Using this formula, in an empirical analysis, we could test the simple versus the variable repackaging hypothesis using classical hypothesis testing procedures. (i.e. fuel price on auto price). A 6 : Yerger(1995) applied Grilitch and Otha method to discuss an article written by Ho¤er and Pratt which was inspired by Akerman approach.

HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2.1 Introduction A lease is a contract in which one party transfers the use of an asset to another party for a speci…c period of time. Leasing equipment is an important means of …nancing, and consequently represents a signi…cant part in many …nancial institutional portfolios. In 2006, leasing represented more than one-sixth of the world’s annual equipment …nancing requirement 1 . The value of the entire Global leasing market was estimated to be more than $633 billion 2 . Academic results suggest that "leasing allows small …rms to …nance their growth, and/or survival while for large …rms, leasing appears to be a …nancial instrument used by sophisticated …nancial managers to minimize the after-tax cost of their capital3 ". In the leasing industry, residual values are the forecasted prices of equipment in the second hand market. A large part of the rent paid by the customer during a life contract is the di¤erence between the list price and the residual value. The leasing company makes money or losses money depending on whether it accurately predicts the value of the asset at the end of the contract (fair market value). If residual values are forecasted to be higher than what the asset is actually worth at lease-end, then there will be a loss. At the opposite, if residual values are forecasted to be lower, then there will be a gain on resale. In the European auto lease market, most leases are closed-end leases : leasing companies assume the residual value risk. In 2001, car resale’s price fell dramatically. As a result, US leasing companies su¤ered large losses, and some even dropped out of the business4 . Although, residual value risk is a key element in the leasing industry, there is very few literature on the subject. The few studies were developed in three main areas : operational purpose5 aiming 1 Percentage market penetrations are highly signi…cant in United states (27.7%), Germany (23.6%), and Spain (29.1%). 2 According to the White Clarke Global Leasing report (2008), "Globally, the industry continued to growth robustly, with the top 50 countries increasing volume by 8.8%" between 2005-2006. The Percentage of the world market volume was respectively 41.1% and 38% for Europe and North America. 3 See Lasfer and Levis (1998). 4 See Gordon (2001) for a description of the 2001 Leasing industry crisis. 5 Jost and Franke (2005) illustrate the use of a speci…c tool of statistical modelling to calculate residual value through a wide range of parameters. In Lucko (2003) and Lucko, Anderson-cook, and Vorster (2006), residual values are set using regression methodology. Rode, Paul, and Dean (2002) outline a framework for analysing the uncertainty of residual value for assets, such as power generation facilities, for which few data points exists. 2.1. INTRODUCTION 39 to set the most accurate residual value ; Basel 2 requirements6 calculation of reserves. Studies evaluate Basel 2 accuracy, and reserve calculation in relation to speci…c credit risk in the leasing industry, and Leasing Contract Valuation7 ; in the valuation analysis, the residual value risk is included through an American option. It allows a comparison of leasing (…nancial lease and operating lease) v.s. purchase decision. Unfortunately, it does not aim to hedge the speci…c Residual value risk, let-alone the correlation issue in a portfolio of equipment. A lack of development on …nancial products hedging residual value risk lead my research to credit risk. The recent important contributions in …nance modelling and in new …nancial products were in credit derivatives. This implies a change in credit management involving banks and other …nancial institutions. A credit derivative is a contract between two parties that allows the use of a derivative instrument to transfer credit risk from one party to another. The risk seller has to pay a fee to the risk buyer who will take the risk. Over the last ten years, the credit derivative market has faced a substantial increase. A lot of credit risk models have been developed, therefore increasing investor interest8 . In 2000, Li‘s Gaussian copula model 9 facilitated a dramatic success of this derivative sector. He proposed a fairly easy, and intuitive model depicting the payment default of a company like the survival probability of a human life10 . It was also a new tool to evaluate the ongoing issue of credit risk ; i.e. correlation. For instance, in a basket of loans there is an individual risk component. Each loan has a risk to default its payment. The systemic risk is the other component. An economic downturn could also impact the whole portfolio, and the systemic risk implies correlation. 6 Schmit produced several articles on Credit risk in leasing industry to analyse Basel 2 requirements accuracy. See Schmit (2003), Schmit (2004), Irotte, Schmit, and Vaessen (2004), Laurent and Schmit (2007). 7 T. Copeland and J. Weston (1982) apply an American put with a decreasing exercise price and S.E Miller (1995) includes an American Call Option in a net present value formula to estimate the internal rate of return of the deal. S.R Grenadier (1995), focusing on the real estate arena, adds a residual value insurance that is equivalent to a put option on the underlying asset in the pricing of a variety of leasing contracts. 8 “At the risky end of …nance”The economist (April 21st 2007) gives an up to date on the credit derivatives market : “According to the Bank for International Settlements, the nominal amount of credit-default swaps had reached $20 trillion by June last year. With volumes almost doubling every year since 2000, some reckon the CDS market will soon be worth more than $30 trillion”. 9 See Li (2000). 10 In “Gaussian copula and credit derivatives”the Wall Street Journal (September 12, 2005) tells the story of David Li discovery and his impact on …nancial markets. 40 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Collateralized Debt Obligation (CDO) turns the correlation problem into a solution. It is a credit derivative created from a portfolio of debt instruments11 . The risk seller transfers the risk implying that the risk buyer takes the risk. Of course, the risk seller has to pay a fee to the risk buyer. The CDO became a successful product by allowing the credit risk division among di¤erent tranches. Synthetic CDOs12 , in particular, were booming, improving liquidity, and allowing corporate bonds to be sliced and diced on the basis of risk. Investors were able to choose di¤erent levels of risk and returns13 . The growth was so huge that it had a global macroeconomic impact, decreasing the risk of default impact, in‡ating asset prices and narrowing credit spreads14 . Prior to summer 2007, there was up to 30% of banking investment pro…t. From that time, all products have slumped suddenly in value due to fraud, and low quality loan underwriting. The "credit crunch" allowed identi…cation of several weaknesses in the industry of loan securitization. Severing the link between borrowers and risk takers, it promoted a lack of accountability. In addition, market protagonists contributed to a credit bubble15 . Investors did not fully understand the products and had an over reliance on ratings provided by specialized agencies. Moreover, some securities were poorly structured. Thereby, on a cleared market with more incentives, some experts are hoping for a recovery. Fortunately, securitization is not con…ned to consumer or corporate loans. Residual value risk and credit risk have a clear analogy, constituting of units that are more or less risky. A lease portfolio is similar to a loan portfolio, both could be divided into systematic and idiosyncratic risks. Losses occur when certain events happen, and again, the correlation risk has a huge impact. Hedging a portfolio of leasing equipment using derivative securities is 11 Collateralized debt obligations divide the credit risk among di¤erent tranches : First senior tranches (rated AAA), second mezzanine tranches (AA to BB), and …nally equity tranches (unrated). Losses are applied in reverse order of seniority. Therefore junior tranches o¤er higher coupons to compensate for the added risk. 12 Synthetic CDOs do not own cash assets like bonds or loans. Using credit default swaps (a derivatives instrument), synthetic CDOs gain credit exposure to a portfolio of …xed income assets without owning those assets. 13 See Hull (2005). 14 « La multiplication des émissions de CDO semble avoir contribué au resserrement prononcé de spreads intervenu au cours de ces deux dernières années sur l’ensemble des marchés de crédit » . Cousseran and Rahmouni (2006). See also “At the risky end of …nance” The economist (April 21st 2007). 15 “Fear and loathing, and a hint of hope” The economist (February 14th 2008). 2.1. INTRODUCTION 41 attractive, and the idea to use some of the signi…cant developments in Credit risk modelling is attractive as well. Therefore the aim of this chapter is to transfer a model from the credit risk to the residual risk. The one factor model is presented and modi…ed. This modi…cation allows the creation of a new product, the Collateralized Residual Value. Pykhtin and Dev (2003), …rst applied the one factor model to auto lease. They calculated the economic loss associated to residual risk, leading to an estimate on economic capital. The model was constructed and modi…ed for …nancial lease with the option to buy out (the lessee has a purchase option at the end of the contract). Moreover, loss distribution was calculated for a …ne grained portfolio (speci…c to large portfolio without signi…cant individual exposure), as a result, the model was only driven by the systematic factor. Our study is somewhat di¤erent, as we aim to hedge residual risk using a derivative …nancial product. This second chapter is intended for people within the leasing industry interested by an innovative …nancial product, as well as people from the …nancial market concerned by leasing risk opportunities. More speci…cally, we aim to hedge risk for a classical European contract. The product should cover operating lease contracts on a de…ned number of units and de…ned characteristics equipment parameters. We complete this theoretical development by an empirical analysis in which we confront this new derivative with market reality. The rest of the chapter is organized as follows : Sections 2 and 3 provide some backgrounds on residual value risk and CDO pricing ; Section 4 describes the model and the …nancial product ; Section 5 is devoted to the empirical analysis and Section 6 concludes. 42 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2.2 Leasing The initial idea of leasing is that it is the use of equipment in a business which produces bene…ts, not the ownership. One characteristic of ownership in leasing contract is the residual value risk that generates competitiveness or losses. 2.2.1 Main characteristics As previously mentioned, a lease16 is a contract between two parties where a party (the lessor) provides equipment for usage on a speci…c period of time to another party (the lessee) for speci…ed payment. Three parties are involved in the process : equipment suppliers, lessors and lessees. The lessor is the party that grants the use of the asset to the lessee. The lessee is the party that obtains the use of the asset from the lessor. The lessor purchases the equipment to the supplier. All along the contract, the lessor has the legal ownership of the asset. To use the asset, the lessee makes periodic payments to the lessor at an agreed rate of interest. There are two families of lease contracts. An operating lease can be considered as a typical rental allowing the lessee to use an asset without owning it. A …nancial lease aims to transfer all risks and rewards of ownership to the lessee. A lease is de…ned as a …nancial lease if it contains one of the following elements : - The ownership of the asset is transferred to the lessee by the end of the lease term. - The lessee has an end of contract option to buy the asset lower than the fair market value. - Whether the asset is transferred or not, the lease period is for a majority of the asset useful life. - Because of the specialized nature of the asset, the lessee only can use the equipment 16 Leasing de…nitions and legislations are quite di¤erent from a country to another. As we do not wish to focus on a speci…c legislation, de…nitions are made on an international common perspective. 2.2. LEASING 43 without major modi…cation. Otherwise, it is an operating lease17 . A lease is a …nancial instrument for the procurement of equipment. Recovery rate on a lease is higher than on a standard loan. But why do enterprises lease ? Regarding large …rms, leasing minimizes the after tax cost of their capital. For small asset base companies, leasing increases access to equipment …nance. The inherent value of the purchased asset acts as collateral. The lessor is the owner of the equipment, and then is secured by the collateral. Another attractiveness is the leasing companies expertise. Leasing companies are not only intermediaries. Their expertise is a real added value in the leasing process. They have knowledge of the asset. They select the appropriate equipment based on the ability of the asset to contribute to cash ‡ow (through various parameters like equipment characteristics, economic life of the asset, taxes or residual value risk). Leasing companies have also skills in …nance, credit, equipment acquisition and dealing. All things considered, they facilitate the ‡ow between equipment suppliers and equipment users. On lessor side, there are several key elements : - Asset leased : Used by the lessee for business purpose, it could be any kind of equipment (i.e. printers, trucks...) - Asset list price : The lessor is usually able to negotiate rebates and the lessee could be part of the acquisition process. - Lease period : It is a pre requisite agreement between the parties. According to the contract, it could be ‡exible. - End of term options : At the end of the contract, there are options allowed to the lessee ; Lease period can be extended, lease can be renewed, equipment can be bought or returned. 17 In the next sections, we propose a model to hedge residual value risk on an operating lease that is the most common contract in Europe for Auto Lease. The model can be extended and modi…ed for a …nancial lease (see Pykhtin and Dev (2003)). 44 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES - Residual value : The lessor forecasts the market value of the asset at the end of the contract. - Depreciation : It might be seen as the variance between the List price and the Residual value all along the lease period. - Lease payment : As illustrated by Figure 1, several features are included in payments made by the lessee during the contract : depreciation of the asset (usually the larger component), interests on the lessor investment, servicing charges (including operation cost, insurances, counselling, repairs...). Figure 1 : Lease rental calculation 2.2.2 Residual value risk versus competitiveness The residual value risk corresponds to the fact that the lessor faces the risk to not being able to recover su¢ cient capital value from the resale or disposal of the asset. As illustrated by Figure 2, the fair market value curve implies a gain on sale or a loss on sale depending on the 2.2. LEASING 45 level of the residual value. Figure 2 : Depreciation curve Therefore the lessor faces a dilemma : The higher the residual value, the higher the risk of loss on sale. But the higher the residual value, the higher the rental payment. At the same time, the higher the rental payment, the worse the competitiveness. Conversely the higher the residual value risk, the better the competitiveness. Figure 3 displays the mechanism of competitiveness and sales results at the end of the contract. 46 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Figure 3 : Dynamical bene…ts In others words, the lessor has to set a residual value to minimizing residual value risk and maximizing competitiveness. A solution would be the use of a …nancial product. Hedging residual value risk could be done through a security derivative. Security de…nition includes …nancial security (bond, stock) but also capital market securities (mortgage, long-term bonds). It is an investment instrument which o¤ers evidence of debt or equity. A security derivative is a …nancial security whose value is derived in part from the value and characteristics of another security, the underlying asset18 . It would allow the lessor to transfer the risk to a fourth party (i.e. insurance company, …nancial market...). 18 Securitization is the process of aggregating similar securities that can be transferred or delivered to another party. 2.3. MODEL PRE REQUISITES 2.3 47 Model pre requisites Because it allows to create a link of two survival functions, Gaussian Copula is a key element in our analysis. CDO pricing, default modeling, and the one factor model are also inherent to the …nancial product presented in Section 4. 2.3.1 CDO are a subclass of ABS Asset Backed Securities are securities backed by a pool of assets. ABS include various subclasses ( Commercial Mortgage Backed Securities (CMBS) or credit card ABS...), depending on the underlying asset class. Obligations are usually underlying Collateral Debt Obligations (CDO). The basic idea of CDO is to pool corporate bonds and selling o¤ pieces of the pool. A synthetic CDO replaces pool’s bonds by speci…c credit derivatives, Credit Default Swaps (CDS). All in all, CDS are triggered by a credit event. A credit event increases the likelihood that the rating of a bond decreases. Consequently, a credit event increases the risk that a bond issuer will default, by failing to repay principal and interest in a timely manner. The events triggering a credit derivative are de…ned in a bilateral swap con…rmation. It is a document that refers to an agreement between the two swap counterparts. There are several standard credit events that could be referred to in credit derivative transactions : Bankruptcy, Failure to Pay, Restructuring, Repudiation, Moratorium. By selling a CDS, an investor can take exposure to an individual credit. He is receiving periodic payment from his client. At the same time, however, he has to pay contigent payment when default occurs. The client, conversely, can hedge individual credit by buying a CDS. He provides periodic payment to the client and receives contingent when default occurs. 48 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2.3.2 Default, default, default.... Default modeling is about the expected default payment of an obligor in a bank credit portfolio. The obligor (or debtor) is an individual or company that owes debt to another individual or company (the creditor). The obligor borrows or issues bonds. The following framework de…nes our model. The model is underlaid by a probability space. This probability space is constituted of three parts. F, a into a sample space called Algebra, is the information available . Elements of F are the measurable events of the model. Events of default are measurable. For instance, the event that an obligor survives or defaults is a measurable event. The last element is Pr, a probability measure. Pr(default) is the probability of default. Finally, to summarize, the probability space ( ; F; Pr) is underlying our model. In survival analysis, T is a random variable denoting the time of default and t are other di¤erent times. If T > t, then the obligor defaults. The survival function, usually denoted S is de…ned as S(t) = Pr(T > t). This function must be non increasing : S(t + 1) S(t). We can now de…ne the complement of the survival function. Usually denoted F , it is a lifetime distribution function : F (t) = P r(T S(t). From this concept a default t) = 1 rate per unit time can be calculated, the event density. Usually denoted f , it is the derivative f (t) = d F (t). dt All of this allows the de…nition of an advanced function, the hazard function. The hazard function, usually denoted , is the event rate at time t conditional until time t or later. It is R1 0 (t)dt (t)dt given by (t)dt = Pr(t T < t + dt j T > t) = fS(t) = SS(t) ( (t) 0 and 0 (t)dt = 1 with no continuous or monotonic constraints). A cumulative hazard function is (t) = Because (t) = S 0 (t) , S(t) then d dt (t) = Rt 0 S 0 (t) S(t) (u)du. and (t) = log S(t). Several distributions can be used in duration modeling (usually de…ned on R+ ), the most t common one being the exponential distribution (S(t) = e ). 2.3. MODEL PRE REQUISITES 2.3.3 49 Basic elements on Copulas Why do we use copula ? In a portfolio, credit risks are non independent. Copulas are a convenient approach to specify a joint distribution of survival times. Using a copula function, we are able to link the survival function of an obligor to the survival function of another obligor in a portfolio . In our model, we use copula on a three dimensional perspective. For simpli…cation purpose, we will focus on the bivariate distribution function and the two dimensional copula. The following results, however, can be extended to the multivariate case (see Nelsen (2006) and Vershuere (2006)). For a "rigorous" copula de…nition, we …rst have to de…ne the unit square and the concept of subcopula. – The unit square I2 is the product I I where I = [0; 1]. – A two dimensional subcopula is a function C 0 de…ned through the four following properties : 1_ DomC0 = S1 S2 (with S1 and S2 are subsets of I containing 0 and 1). 19 2_ C0 is grounded . 3_ C0 is 2-increasing (for every x1 x2 and y1 y2 , H(x1 ; y1 ) H(x2 ; y2 )). 4_ For every u in S1 and every v in S2 , C0(u; 1) = u and C0(1; v) = v. We are now able to de…ne a two dimensional copula : It is a two dimensional subcopula C whose domain is I2 . Figure 4 gives an intuitive notion of a two dimensional copula. The graph of a two dimensional copula is a continuous surface within the unit cube I 3 . 19 A function H from S1 S2 is grounded if H(x; a2 ) = 0 = H(a1 ; y) for all (x; y) in S1 being the last elements of S1 and S2 . S2 with a1 and a2 50 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Figure 4 : Two dimensional copula Two others elements are fundamental in our analysis ; the joint bivariate distribution function and the Sklar Theorem. A joint bivariate distribution function is a function H with domain R2 such that H is 2-increasing : H(x; 1) = H( 1; y) = 0, and H(+1; +1) = 1. The joint bivariate distribution func- tion is a key element of the Sklar Theorem : Let H be a joint distribution function with margins F and G. Then there exists a copula C, such that for all x; y in R, H(x; y) = C(F (x); G(y)): Furthermore, if F and G are continuous, the copula C is unique. Otherwise C is uniquely determined on RanF RanG. Conversely, if C is a copula and F and G are distribution functions, then H is a joint distribution function with margins F and G: We can now include random variables. Let X and Y be random variables with distribution functions F and G, and joint distribution function H. Then there exists a copula C with H(x; y) = C(F (x); G(y)). If F and G are continuous, C is unique. Otherwise, C is uniquely 2.3. MODEL PRE REQUISITES determined on RanF 51 RanG. In a few words, a copula function is a function that links univariate marginal to their full multivariate distribution : C(u; v) = Pr(u V ). Therefore, using a copula function, we U; v are able to link the survival function of a credit risk to the survival function of another credit risk in a portfolio. 2.3.4 Speci…c pre requisites, the Gaussian copula In the model presented in this chapter, we use the Gaussian copula. Let normal distribution function with correlation coe¢ cient (0 be the bivariate 1). The bivariate normal is a member of the family of elliptically contoured distributions. The density function of is (x; y) = 2 ( p1 2 1 e 1 2(1 2 ) (x 2 +y 2 2 xy)) . The densities for such distributions have contours that are concentric ellipses with constant eccentricity. 1 is the inverse of a normal distribution function. 1 Finally the Gaussian copula is C(u; v) = ( 1 (u); (v); ). Consequently, variables are jointly elliptically distributed and we can set using a linear correlation as a measure of dependence : Let X and Y follow, respectively, the distribution F and G. They jointly follow the distribution function H. Then the linear correlation for X and Y is de…ned, using u = F (x) and v = G(y) as = (X; Y ) = p 1p V ar(X) V ar(Y ) R1R1 0 0 [C(u; v) uv]dF 1 (u)dG 1 (v). Another property of the bivariate normal distribution is radially symmetry. A bivariate normal distribution with parameters ( x, y ). It means that H( x + x; y 2 x, 2 y and + y) = H( x x; x, y, is radially symmetric about the point y y). Using copula, we are able to work on survival function. Indeed, for a pair of random variable with joint distribution function H(H(x; y) = P [X < x; Y < y]), the joint survival function 52 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES copula is given by H(x; y) = P [X > x; Y > y] = 1 H(x; y) = 1 F (x) G(y) + H(x; y) = H(x; y). The relationship is 1 + F (x) + G(y) + C(1 F (x); 1 G(y)). In the next section, we assume that the correlation of default is driven by a common factor through a Gaussian copula. 2.3.5 The initial one factor model is used for CDO pricing To resume the model in one sentence, a …rm defaults when its “asset value-like”stochastic process X, falls below a barrier. X is commonly identi…ed as the amount of assets and X the barrier as the amount of liabilities. The …rm defaults when the amount of assets is below the amount of liabilities. The idea was …rst introduced by Merton (1974). He transferred an option pricing model to the credit risk market. Then he applied the Black and Scholes model to credit risk. We present an alternative model using copula. Value added is in copula ‡exibility to dependent variables and copula ability to provide scale invariant measure of association between random variables. The intuitive aspect of this model contributed to the growth of credit risk market. The model described below is the famous standard Gaussian copula developed by Li (2000) and exposed20 by Gibson(2004). In a reference portfolio of i = 1; :::N credits, for each obligor, default payment occurs when xi (reference credit normalized asset value) falls below xi (the threshold). x i = ai M + q (1 a2i )Zi (2.1) xi has three main components : M , Zi , and ai . M is the common factors a¤ecting all the credits, the systematic risk. Zi is the factor a¤ec20 See also Meneguzzo and Vecchiato (2004) for an empirical study of credit derivatives within the copula framework. Cherubini, Luciano, and Vecchiato (2004) give an overview of copula applications in Finance. 2.3. MODEL PRE REQUISITES 53 ting only credit i. ai is the correlation parameter (0 6 ai 6 1) and de…nes default dependency between companies in the economy. The correlation of asset values between credits i and j is equal to ai aj . The random variables are assumed to be independently distributed. Therefore unconditionally on the systematic risk, default payments are correlated but conditionally there are independent. M , Zi , and xi are zero-mean, unit variance random variables with distribution functions G(0; 1), Hi (0; 1), and Fi (0; 1). qi (t) is a risk neutral probability that credit i defaults before t. The default threshold xi is equal to Fi-1 (qi (t)). When does a default happen ? A default happens when xi falls below xi . But xi falls below xi if F (xi ) < qi (t) , xi < Fi-1 (qi (t)) , ai M + and …nally Zi < F 1 (q pi (t)) 2 ai M p 1 a2i Zi < F 1 (qi (t)) 1 ai Conditional on the value of the factor M , the probability of default is therefore qi (t=M ) = H 1 ( F 1 (qi (t)) ai M p ) 1 a2i (2.2) For any number of defaults in a portfolio of N obligors, we have to estimate the probability of default on time t and conditional on the common factor M . Therefore, we set the number of default distribution using a binomial function21 . P N (l; t=M ) = l qi (t=M ) N (2.3) Once we have the conditional default distribution, we estimate the distribution according the distribution of M . 21 The number of default distribution is usually computed through a recursion method (Andersen, Sidenius and Basu (2003) or Hull and White (2004)). In the case of homogeneous credits and for simpli…cation purpose, a binomial function is simpler and lead to similar results. 54 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES The unconditional default distribution P N (l; t) can be calculated as N P (l; t) = Z 1 P N (l; t=M )g(M )dM: (2.4) 1 In a CDO, the investor is responsible for the interval of loss [L; H]. The expected loss of a CDO is de…ned on [L; H]. We de…ne the loss for any default as A(1 R) with A the notional amount of credit and R the recovery rate. The expected loss is ELi = N X P N (l; Ti ) max(min(lA (1 R); H) L; 0) (2.5) l=0 with T i, i = 1; :::; n the periodic payment. Now, how to price a CDO ? A CDO contract speci…es two potential cash ‡ow streams : a Contingent leg and Fee leg. – On the contingent leg side, the protection seller makes one payment only if the reference credit defaults. The amount of a contigent payment is the notional amount multiplied by (1 R). The contigent leg is contigent = n X Di (ELi ELi 1 ) (2.6) i=1 with Di the risk free discount factor for payment date i (e rt , with r the risk free rate). The risk free discount factor is usually derived from the risk free interest rate. – On the …xed leg side, the buyer of protection makes a series of …xed, periodic payments of CDO premium until the maturity, or until the reference credit defaults. 2.4. A MODIFIED MODEL : THE LEASING MODEL 55 The expected present value of the Fee leg is F ee = s n X Di i [(H L) ELi )] (2.7) i=1 i is the accrual factor for payment date i and s is the spread per annum paid to the tranche investor ( i Ti Ti 1 ). The value of the CDO contract to the tranche investor at any given point of time is the di¤erence between the present value of the contigent leg and the present value of the …xed leg. It is the di¤erence between the protection the buyer expects to pay, and the amount he expects to receive. – The Mark To Market value of the tranche, from the perspective of the tranche investor is M T M = F ee Contigent (2.8) At inception the mark to market is equal to 0, therefore the spread is s= P n Contigent Di i [(H L) (2.9) ELi )] i=1 2.4 A modi…ed model : The leasing model From equipment leasing speci…cities and the one factor model, we create a residual value risk model. A new product called Collateralized Residual Value (CRV) is adjusted through the leasing contract parameters. 56 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2.4.1 There is a similarity between credit risk and residual value risk. But there are also dissimilarities and speci…cally in Auto Lease. The main idea of the leasing model is that a portfolio of leased equipment is comparable to a portfolio of credit. A portfolio with losses on resales is equivalent to a portfolio of credit with companies defaulting. – As in a CDO, every unit into the lease portfolio, has an idiosyncratic and a systematic risk ; asset speci…c characteristic impact is resale price (model type, obsolescence. . . ). At the same time, resale price of other assets has a signi…cant impact (bid and ask e¤ect, downturn on the resale price market, in‡ation etc.. . . ). There are also dissimilarities : – First of all, equipment units are resold only one time at the end of the contract, although for a CDO, there is a risk of default throughout the contract. Therefore, the model presented in the next section is set for only one period. – Another dissimilarity (and not the least) is on correlation estimation. Di¤erence is not on calculation but on data source. In credit risk, they are four main data sources available : -Default events that are obviously concrete realization of credit risk. They are rare events and as a result there are usually few data available. Approximations and aggregation have to be made to constitute data bases. -Companies credit ratings : They are provided by credit agencies and re‡ect the credit risk of a company according to experts points of views. By and large, they are made through balance sheet and macroeconomic analysis. -Credit spreads : They re‡ect market perception of credit risk. A large amount of data is available. But spreads could be impacted by external elements like liquidity 2.4. A MODIFIED MODEL : THE LEASING MODEL 57 -Equity correlation : The factor model (cf Section 3), assumes a theoretical link between equity and credit risk. Correlations are then more easy to compute. In residual risk, there is one main data source available : for a residual value calculation, inputs are observations from second hand markets. Correlation estimation of residual value is based on resale market statistics. Resale prices, asset characteristics and price index are used to set modelization variables. A large amount of data is available. – The last dissimilarity is on standard de…nitions. As multiple factors de…ne a resale, there are issues to de…ne resale asset classes or homogeneity prices. Auto lease is an extreme illustration. The high price level in the automotive second hand market involves a high residual value level. Combined to a competitive leasing market, the level of price leads to high risks of loss on sale. At the same time, automotive is a singular equipment. A car is not only a tool to go from a place to another. It is also a living place and a symbol. Automotive often re‡ects driver’s sociological characteristics. The purchase of a vehicle is a sensitive act, even in business. Therefore, Auto lease is a wide area to analyze. In automotive market multiple factors in‡uence resale price. A second hand vehicle price is impacted by age (time between registration date and resale date), mileage (number of kilometers at the end of the contract), damages (i.e. amount and type ), product life cycle (i.e. new model...), make (i.e. Toyota, Renault...), model (i.e. Yaris, Laguna...), version, body type (i.e. break, pick-up...), segment (i.e. small cars...) or external color. Figure 5 gives an overview. Choices have to be made to de…ne similar assets and prices (c.f Section 5). 58 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Figure 5 : Multiple factors of automotive market 2.4.2 Homogeneous equipment type model The initial idea is simple : we use the equipment resale value as the asset value-like xi and the probability of resale value below residual value (xi <xi ) as the probability of default. In a reference portfolio of i = 1; :::N units (vehicles, equipment...), for each obligor, losses occur when xi (reference unit normalized asset value) falls below xi (reference unit normalized residual value). q xi = ai M + (1 a2i )Zi (2.10) -The correlation of resale’s prices between units i and j is equal to ai aj . -M is the sectorial factor a¤ecting equipment units on resale’s market and Zi is the risk of 2.4. A MODIFIED MODEL : THE LEASING MODEL 59 loss on resales on unit i -Xi, M , and Zi are zero-mean, unit variance random variables with distribution functions Fi (0; 1), G(0; 1), and Hi (0; 1).The random variables are assumed to be independently distributed. At that point, the construction is similar to the credit model, but we include residual risk. Resale’s value can be lower than residual value. There is a risk of loss on sale. Three new elements will have an impact on the leasing adjustment of the model. Vi is the residual value or in other words the expected fair market value. mF M Vi is the historical average fair market value, eF M Vi is the historical standard deviation. mF M Vi , eF M Vi , and Vi are set on a percentage of Lp, List price by unit. As an example, an asset bought e 10000 and leased for a Residual value of e 5000 has Vi = 50%. Then residual risk is added : Probability of loss at the end of the contract is qi (t). qi (t) is a variable with mean mF M Vi , variance eF M Vi , and distribution function Ei (mF M Vi ; eF M Vi ) The probability of loss depends on residual value : qi = Ei (Vi ). So default threshold xi is equal to Fi-1 (qi ). Conditional on the value of the sectorial factor M , the probability of default is therefore qi (M ) = H 1 ( F 1 (q ) ai M pi ) 1 a2i Again, conditional probability is P N (l; M ) = R1 can be calculated as P N (l) = 1 P N (l)g(M )dM . l N (2.11) qi (M ) and the unconditional probability As a result the recovery rate is equal to the probability of loss. By construction the recovery rate is R = qi. The loss on sale for any unit is (1 R)Lp. Finally, resale price becomes RLp. Previous elements allow the creation of a …nancial product, inspired by Collateral debts obligations : 60 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES The Expected loss is EL = N X P N (l) max(min(Lpl (1 R); H) L; 0) (2.12) l=0 The contigent leg is contigent = n X Di (EL) (2.13) L) (2.7) i=1 The premium leg is again F ee = s n X Di i [(H ELi )] i=1 The spread is again s= P n Contigent Di i [(H L) (2.9) ELi )] i=1 2.4.3 Heterogeneous equipment type model : a portfolio of three different assets The model is extended to a portfolio with non similar units. A company ‡eet is commonly constituted of various car models. In an European leasing contract for medium size European company, lessee usually request di¤erent categories of cars for an auto lease contract. The ‡eet is usually divided into three groups : Executives’cars (usually high brand car), Employee cars (medium level cars) and Small cars. Basically the construction is similar to the homogeneous equipment type model (cf Section 4.2). 2.4. A MODIFIED MODEL : THE LEASING MODEL 61 Three representative’s vehicles constitute the model : Ex, Em and Sm. Now there are di¤erent types of asset residual values, number of units, List price etc.... V 1i , V 2i ,V 3i are residual values for groups 1, 2, 3, mF M V 1i ,mF M V 2i , mF M V 3i , are fair market values historical averages, eF M V 1i ,eF M V 2i ,eF M V 3i are historical standard deviation historical averages. mF M V 1i , eF M V 1i , and V 1i are set on a percentage of List price. The recovery rate for group 1 is R1 = q1i, the loss on sale for any unit is R1(1 Lp1) with Lp1 unit list price. Indeed, resale price is R1Lp1. The principle is the same for others groups. For each vehicle, asset value is still xi = ai M + p (1 a2i )Zi : For group 1, default threshold xi is equal to Fi-1 (qi ) with q1i = Ei (V 1i ) and Ei (mF M V 1i ; eF M V 1i ). The principle is the same for other groups. The distribution of the number of defaults, conditional on the common factor M, is computed for each group as P N1 (u; M ) = w N3 u N1 q1i (M ), P N2 (v; M ) = v N2 q2i (M ) , P N3 (w; M ) = q3i (M ) with N1 ; N2 ; N3 number of units, P N1 ; P N2 ; P N3 the conditional probabilities, and u; v; w number of defaults for group 1, 2, 3. The probability of default is computed on the whole portfolio. P N (u; v; w; M ) = P N1 (u; M )P N2 (v; M )P N3 (w; M ) The Expected loss is : EL = N X P N (u; v; w; M ) max(min((Lp1u (1 R1))+(Lp2u (1 R2))+(Lp3u (1 R3)); H) L; 0) l=0 Premium leg, contigent leg and spread are calculated like in 4.2. (2.14) 62 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES It is straightforward to generalize this approach to more than three vehicle types. 2.4.4 Collateralized Residual Values We propose a …nancial product, the Collateralized Residual Value, that covers residual value risk. We display a sensitivity analysis of the CRV to the main characteristics of the leased asset. A CRV is a new class of ABS The Collateralized Residual Values (CRV) is a new class of Asset Backed Securities (ABS). The CRV is inspired by synthetic Collateralized Debt Obligations (CDO) structure. Like a CDO, CRV can be sliced and diced, and tranches can be sold. But CRV is not about credit risk. The purpose is to hedge residual value risk on a portfolio of leases. A credit derivatives, obviously, is more accurate to hedge credit risk in a portfolio of contract. Sensitivity Analysis on a CRV What is the sensitivity of a CRV to size, residual value, and fair market variance ? In the following sensibility analysis, all underlying reference assets are cars. The portfolio is p homogeneous. List price (e 15000), Fair market value (e 4500) and Correlation ( 0:3) by car are equal. Cars are leased on a three years contract. We value four tranches of the CRV. The …rst tranche absorbs all losses until the …rst 25% of the portfolio, the second tranche until 50%, the third tranche until 75% and the fourth until 100%. 2.4. A MODIFIED MODEL : THE LEASING MODEL 63 Impact of Fleet Size Table 1 : Sensitivity to ‡eet size Table 1 shows that the buyer of protection on a ‡eet of 600 units should be willing to pay 125,21 basis points to hedge the …rst 50% losses using a CRV. According to our results, the spread is stable until 500 units. Then the increasing size reduces the cost of protection. An increase in size reduces idiosyncratic e¤ects. There is a diversi…cation of risk. 64 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Impact of Residual Value level Table 2 : Sensitivity to residual value The higher the residual value, the higher the pricing of CRV (Table 2). As illustrated in Section 2.2, decreasing residual value reduces the risk of loss on sales. 2.4. A MODIFIED MODEL : THE LEASING MODEL 65 Impact of Fair Market Value variance Table 3 : Sensitivity to fair market value variance Fair market value distribution tails depends of FMV variance (Table 3). For an higher variance, tail are larger. As a result, the spread is an increasing function of the variance. 66 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2.5 Empirical analysis The model is applied to a six years historic resale’s portfolio. The observations, between 2000 and 2008, are from a major European leasing company (General Electric Capital Solutions). We …rst estimate the correlation of assets to a common factor. Then fair market value parameters and residual value are estimated. 2.5.1 Correlation to the one sector factor According to section 4.2, we have to set the linear correlation (ai ) between the portfolio and a sectorial factor a¤ecting equipment units on resale’s market (M ). The sectorial factor is assessed using Eurostat Harmonized Consumer Price index (HCPI22 ). The index Purchase of vehicles price allows comparison within European markets. Additionally, a portfolio index has to be created. The portfolio index provides a non-biased historical trend analysis and exposes portfolio sale price at di¤erent times. Automotive Price Index To set a common factor that would a¤ect the whole portfolio, several HCPIs are available ; HCPI all items, HCPI Energy, HCPI Petroleum products, HCPI Road transport equipment. The Index "Purchase of vehicle" (Figure 6) appears to be the most relevant. It covers purchases of new vehicles and purchases of second-hand vehicles from other institutional sectors. It is available by country and on European level. This index is included in the modelization as the sectorial factor indicator (M ). Vehicle customers have to choose between resale market and new market. As a consequence, resale market is strongly impacted by new vehicle market. Therefore, a positive or a negative correlation of the sectorial index with the portfolio can be expected. 22 Graphics of HCPI series are reported in Appendix. 2.5. EMPIRICAL ANALYSIS 67 Figure 6 : European HCPI Portfolio Index Creation and Computation A large amount of parameters impacts resale price and there is a non homogeneity of the portfolio mix from one month to another. As a consequence, average price never re‡ects accurately portfolio sales price variance through time. Therefore a consistent price variable is created through an index replicating a same arti…cial portfolio. The idea is to replicate a portfolio mix to allow time series analysis. Portfolio Index Creation The information comes from resale vehicles statistics from 01/2000 to 01/2008 including France, Germany, Italy, Portugal, Spain and Sweden. We only include normal termination sales (sales types like wrecks or litigations are excluded). Observations with extreme and incorrect values are cleaned. High damages (95th decile by country) that would alter resale’s price and therefore are …ltered. Calculation is a …ve-steps process : 1. Creation of buckets for Age and Mileage (details in appendix). 68 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2. Keys are created including the following components : age=mileage=model=f iscalclass=f ueltype=country. 3. Keys with population of less than 100 units on the whole history are excluded. (e.g.GBR=T oyota=previa=private=lightgoods=petrol=_6:33; 39month=_3:75000; 105000km is excluded. During the last 8 years, less than 100 units in this bucket have been sold.) 4. Representative and similar samples are created all along the history using the historical key frequency. A Random selection is processed by month through the following criteria : -1% of units by bucket are selected (e.g. for a bucket of 200 units, then 2 units are selected), Restricted random sampling with replacement (SAS proc survey), -Priority levels : The sample is replicated on a monthly basis according to key frequency and by order of priority ; selected month, semester of the selected month, whole history (e.g. If data are not available in the current month, then data are selected in the current quarter etc...). 5. A monthly resale percentage is computed from the sample. The percentage of resale is resaleprice . Listprice+OptionListprice It allows a comparison of resale performance between vehicles with di¤erent levels of price and option price. The process is replicated several time to create several sample. 1000 random samples are created by month. 2.5. EMPIRICAL ANALYSIS 69 Portfolio Index Computation and results 565 representative buckets are selected from an initial pool of 38257 units. 97000 samples are calculated (97 periods). Among other perspective, it provides a graph distribution by month. Results are available by country and on European level. For instance, Figure 7 displays the simulation result for Portugal on January 2001. The percentage of resale distribution is on a range of [49%-72%]. Figure 7 : Portugal depreciation distribution on January 2001 Estimation of the correlation between the sectorial factor and the portfolio price Time series are seasonally adjusted using the TRAMO-SEATS methodology23 . Graphical results by countries are displayed in Appendix. 23 TRAMO-SEATS : They consist of new versions of programs TRAMO, "Time series Regression with ARIMA noise, Missing values and Outliers", and SEATS, "Signal Extraction in ARIMA Time Series", created by Gómez and Maravall in 1996, of program TERROR, "TRAMO for Errors", and program TSW, a Windows version of TRAMO-SEATS with some modi…cations and additions, developed by G. Caporello and A. Maravall at the Banco de España. 70 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Figure 8 : European HCPI and European portfolio YoY variance Figure 8 illustrates results for Europe. The European HCPI is more stable than the European Portfolio YoY variance value. A Pearson’s product moment is computed on a year on year annual variance, and results are given in table 4. Table 4 : Pearson Product moment on year on year annual variance As expected, results are di¤erent by country. Correlation are negative or positive with di¤erent levels of intensity. Impacts are negative for Germany, France and Italy. If "Purchase of vehicle" HCPI increases, then the resale portfolio performance decreases. Therefore unlike the initial credit model, the correlation parameter could be negative ( 1 6 ai 6 1). 2.5. EMPIRICAL ANALYSIS 2.5.2 71 Fair Market Value and Residual Value setting mF M Vi , average fair market value, eF M Vi , standard deviation and residual value (Vi ) are parameters to include in the model. Fair Market Value estimation is complex We assess the Fair Market value at the end of the contract. In others words, we estimate the depreciation of the asset for the next years. Resale percentage Mean and Variance of resale percentage are calculated from historical statistics. For simpli…cation purpose, resale price is computed through a percentage of List resaleprice ).

Previous graphics illustrate the fact that FMV is not a constant value. There are trends and cycles that are not straightforward to identify. Depreciation in the value of a car occurs based 24 Peugeot 306 is the previous model version of Peugeot 307. 2.5. EMPIRICAL ANALYSIS 73 on a range of factors. The factors include cars condition, kilometers traveled and brand reputation. Moreover, brand reputation contains mechanics and popularity. Consequently, di¤erent methodologies are possible to forecast average fair market value. Leasing industry usually works with internal modelization. Standard models have inside a model life cycle and a segment analysis. New legislations or macroeconomic impacts also are sometime included. Additionally, external companies (Eurotax, X-ray, Cap) provides forecasted FMV. Forecasts are based on market data, modelization and expertise. 74 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES RV and FMV, a new perspective In an operating lease contract, Residual value is de…ned as the forecasted fair market value. It is an input in rental calculation. It also drives the risk of loss on sales at the end of the contract. What is the impact of a CRV ? Elements of the contract become di¤erent. Using securitization product, elements of the contract have to be rede…ned. The fair market value still has to be forecasted. But residual value is now a threshold. As illustrated in Figure 12, the threshold is a level of risk chosen by the lessor and the lessee. In the model, mF M V is a forecasted average of fair market value at the end of the contract. And eF M Vi is the estimated standard deviation of fair market value. So the considered residual value is now an adjustment variable. Therefore the securitization product allows several choices within di¤erent levels of risk, di¤erent levels of rents, di¤erent market spreads, and di¤erent fair market value variances. Additionally, hedging can be made on speci…c tranches. Figure 12 : Sale results through fair market value and residual value level 2.5. EMPIRICAL ANALYSIS 75 For simpli…cation purpose, the threshold is set at mF M V value in the next illustration. It means that the contract position is neither conservative or risk taking. Six CRV Table 5 : Pricing of six CRV A CRV is built accordingly to leasing contract characteristic. As illustrated in Table 5 for six CRV, inputs in pricing are population size, list price, fair market value mean, fair market value variance and residual value. Through the selected residual value level and tranches limits, lessor and lessee can choose a level of risk. Moreover, in case of negative correlation parameter, CRV could go against a downturn in the sectorial market and create opportunities for risk diversi…cation. Like standards derivatives, CRV allows insurance or hedging for the lessor and, for the buyer taking opposite position in the …nancial market, speculation or arbitrary. 76 CHAPITRE 2. HEDGING RESIDUAL VALUE RISK USING DERIVATIVES 2.6 Conclusion Li Gaussian copula model, initially used for credit risk, is transposed in residual value risk of the leasing industry. The Collateralized Residual Value (CRV), a new derivative product, is proposed. Pooling together a large portfolio of equipment that has been leased, the derivative converts end of contract risks into an instrument that may be sold in the capital market. As a standard derivative, it is a tool that transfers risk, and can be used for hedging or speculation. Moreover, it allows the lessor and lessee to select their degree of exposure to residual value risk and to improve competitiveness. As a result, the model is a contribution geared for people from the leasing industry interested by an innovative …nancial product, as well as people from the …nancial market concerned by leasing risk opportunities. The present analysis could be extended in various ways. The accuracy of the correlation parameter can be improved by a complete macroeconomic analysis, and the fair market value parameter can also be improved. Finally, other families of copula could be tested. 2.7. APPENDIX 2.7 77 Appendix Figure 13 Figure 14 78 CHAPITRE 2.

HEDGING RESIDUAL VALUE RISK USING DERIVATIVES Chapitre 3 A Family Hitch Econometrics of the New and the Used Car Markets 81 82 CHAPITRE 3. A FAMILY HITCH 3.1 Introduction Apples are non-durable goods. Out of the new market, they have no value. On the contrary, cars are durable goods. They are usually bought with the intention to be used for a limited time and then re-sold. A car owner can choose for a duration, and then re-sell the vehicle on a well developed secondary market. Thanks to the durability of the car, drivers can resell cars to each other, and buy new or used vehicles. Durability creates speci…c dynamics of overlapping generations of durable goods that are not present in non-durable markets, and brings the question of the interaction between primary and secondary markets. We aim to identify the relationship between new and used car markets in order to forecast car prices. For various industries the future car prices are of special interest. Indeed, among other things, used car market prices directly a¤ect leasing companies losses and bene…ts. The third chapter is organized as follows. Section 2 reviews the literature related to the interdependence between primary and secondary markets, speci…cally in the automotive sector. Section 3 presents the data and our empirical setting. In Section 4, we empirically evaluate the interdependence between new and used cars for three major markets (France, the United Kingdom and the U.S.). Section 5 concludes. 3.2 Academic researches in the second-hand market are legion. There has been a signi…cant amount of academic researches on the subject of durable goods in the second-hand market. The literature discusses why second-hand markets exist and highlights some mechanisms of interdependence between new and used markets, especially in the microeconomy area. It mainly focuses on three related axes of research : the Akerlof e¤ect, the optimal durability and the time inconsistency. Some researches, like Scitovsky (1994), also exist into a Keynesian system. 3.2. ACADEMIC RESEARCHES IN THE SECOND-HAND MARKET ARE LEGION. 3.2.1 83 Why secondary markets exist ? Van Cayseel (1993) provides a framework : Second-hand markets are institutions dealing with transactions of durable goods1 , and the durability constitutes their …rst condition of existence. As a second condition, the good utility needs su¢ cient volatility. For instance, an economic depreciation2 could appear if the consumer has no further need of the good or because the maintenance cost of the car increases3 . Consequently, the second-hand market re-allocates goods from agents extracting a low utility to agents extracting a higher one. Mixing the condition of durability and a possible variance of utility, we can state that the longer the durability, the higher the probability for an asset to change of valuation. The longer the durability, the higher the probability for a consumer to drop the asset, and buy another one. The secondary market could also be a way for some users to drop goods with malfunctions and no functionality4 . But dropping ‘lemons’could only be an incentive for a minority of agents, otherwise the secondary market would collapse. According to Van Cayseel (1993), the possibility of simultaneity of new and used markets constitutes the last condition, raising the question of bene…ts and constraints in the secondhand market for producers. In order to reduce the risk of competition with new products5 , producers would try to prevent the existence of a secondary market (i.e. by only renting their equipment or reducing the substitutability between new and used markets). Fortunately, some incentives to tolerate and to even support a second- hand market, additionally exist for the producer. The …rst incentive would be the pressure created by other competitors with similar goods. Following researches on industrial regulation and anti-trust policies, a large amount of academic papers have studied durable goods in a monopolistic market6 . The incentive could be a law committing the monopoly to sell his products. The existence of asymmetric information 1 2 On a broader de…nition of Van Cayseel, the key concept should be not used goods but resales. We are focusing on second-hand markets for automobiles. Most of the time there is a depreciation of the good over time. However, in some markets like art or …nancial product, the secondary market has a higher valuation than the primary market. Speci…c cars (luxury ones) could also gain value after some years because of collectors interests. 3 Regarding maintenance, the second hand market could be a way to reallocate used goods with high maintenance cost to users who have a better maintenance technology or skills. 4 It brings the problem of adverse selection discussed in the next section. 5 The problem of Time Inconsistency is discussed in section 2.2. 6 See Waldman (2003) for a large review in the microeconomy area. 84 CHAPITRE 3. A FAMILY HITCH could also restrain the opportunity of leasing, because users are less careful with goods they do not own. Anderson and Ginsburgh (1994), through a microeconomic analysis and under a monopolistic assumption, show a bene…cial e¤ect of secondary markets for the producers : consumer heterogeneous tastes result in a segmented secondary market allowing producers to establish a system of indirect price discrimination (by setting higher prices, a producer extracts higher surplus from consumers with higher willingness to pay). In the automotive industry, manufacturers are selling both new and used cars7 . They also rent and provide services of maintenance in order to bene…t most of the needs related to their products (i.e. …nancing car ownership through their …nancial branch). Manufacturers aim to collect various revenues from all available channels. De…ning the automotive industry as a monopoly would be a strong assumption. According to the ACEA8 in 2008, more than 15 manufacturers (through more than 43 brands) were sharing the market in Western Europe, and none of them had more than 21 percent of the market share. In the US, more than 15 automotive makers are competing and none of them had more than 15 percent of market share9 . Paredes (2006) argues that cars are ‘durable experience goods’. Before buying a car, a consumer can’t evaluate all of its characteristics. As a consequence, Paredes states that a link exists between consumer loyalty, satisfaction and retention value. The existence of consumer loyalty (and non loyalty) implies that consumers are able to choose di¤erent manufacturers and that car markets are not monopolistic. As a conclusion, an automotive company could only be de…ned as a monopoly during the introduction of new vehicles (i.e. minivans in the US market10 ). Although we reject a monopolistic assumption, we take these studies into account by focusing on the highlighted mechanisms of interdependence. Scitovsky (1994) adopts a macroeconomic approach to explain the existence of secondary markets. He argues that durable goods are valued by the services they provide to the consumers. Because of time and obsolescence, the amount of services included decreases. Therefore the secondary market has two functions : …rst, it mitigates the inequalities by allowing poor customers to buy a cheaper bundle of services to richer ones. Second, it stimulates the economy 7 8 usually through franchise dealer.

ACADEMIC RESEARCHES IN THE SECOND-HAND MARKET ARE LEGION. 85 by facilitating the replacement of obsolete durable goods. Scitovsky’s theory explains why there are bigger proportions of second-hand markets (i.e. clothes, household appliances) in developing countries. But used car markets have a signi…cant size in countries with high standard of living. Indeed, automobiles are relatively expensive and, by increasing the price span, the second-hand market allows most of people to a¤ord a car. The empirical analysis of Clerides (1998) on the welfare e¤ects of trade liberalization11 in 1993 (by permitting the importation of Japanese cars in Cyprius second-hand market) con…rms Scitovsky’s opinion. Clerides concludes of signi…cant gains that bene…ted predominantly for low-income consumers because of an increase in product variety. 3.2.2 The Akerlof e¤ect and the car durability are linked. The main area of research on durable goods comes from the most famous analysis on automotive second-hand market. Akerlof (1970) explained why used car valuation is so much lower than new car valuation. The automotive resale market is a¤ected by something called the ’lemon e¤ect’. A used car has a probability to be of a good quality or a bad one (i.e. lemon), and the uncertainty on quality implies a price adjustment. In the resale market, there is an asymmetry of information ; the car owner has a better knowledge of the probability of bad lemons. If second-hand vehicles were valued like as new vehicles, then it would attract lemons (sellers of lemons would have the opportunity to sale their vehicles and buy a new one on the new vehicle market) and it would create an arbitraging opportunity. Akerlof used the automotive market as a best illustration and extended his idea to other markets (the cost of dishonesty...). The Akerlof’s article helps to understand why an adverse selection happens, as well as the large variance and the trends between new and second-hand prices. But some elements of the article have to be discussed. First, the in‡uence of new markets misses in the analysis. Hendel and Lizzeri (1999a) built a microeconomic model including a primary market and according to their conclusions, a su¢ cient level of trade could reduce the adverse selection. Moreover, buying new cars and selling used cars are complementary activities : even if they give higher valuation to their used units, owners 11 In spite of the limitation of the study focusing on a country without a national automotive industry. 86 CHAPITRE 3. A FAMILY HITCH …nd optimal to sell their good quality cars ; once their used car has been sold, owners place a higher value on purchasing a new car. Finally, Hendel and Lizzeri argue that new market prices could be increased thanks to the adverse selection. The …rst explanation would be that a used good becomes a worse substitute than a new one (in case of an average quality reduction on the used market). The second reason would be that the buyer of new goods gets an option value and he or she can decide to keep the high quality realization of the used car. Empirical analyses give a second perspective. Winand and George (2002) provided a large review of empirical tests on the Akerlof e¤ect and in various markets, as well as a speci…c analysis, in the second-hand car market of a Swiss canton. According to their conclusions, adverse selections are not always observed or could occur under a mitigated and non widespread form. Car durability constitutes a third element. An increase of average durability, through the Akerlof analysis, could have either a negative or a positive e¤ect. A better durability implies a better quality of cars producing a lower probability of ’lemons’on the second-hand market. On the other hand, consumers would keep their car longer and it would increase the proportion of ’lemons’. Whatever the consequence (positive or negative for pro…ts), a manufacturer can impact the adverse selection e¤ect through guaranteed warranties, buyback or by improving information on the second-hand vehicles. Similarly, by the beginning of the 90’s, Peach et al. (1996) noticed an improvement of the information availability on the US second-hand market and an increase of car durability. At the same time, the used car market experienced an increase of sales and a¤ordability. All in all, it suggests a positive correlation between quality, durability, and non-adverse selection. To conclude, the Akerlof e¤ect and the durability could explain the price trends through the structure of the market and the inner quality of cars. The questions of quality and optimal durability are developed in the next section. 3.2. ACADEMIC RESEARCHES IN THE SECOND-HAND MARKET ARE LEGION. 3.2.3 87 Optimal durability and Time inconsistency are two areas of research. Optimal durability constitutes another main area of research in the microeconomic analysis of durable goods. A non-competitive market might lead to a lower socially e¢ cient durability of goods in order to constraint consumers to increase purchase frequency. Sieper and Swan (1973), however, argue for an absence of durability distortion : monopoly market and competitive markets will always produce at minimum cost and then consider the durability as a minor problem. Some articles, like Hendel and Lizzeri (1999b), contest these outcomes : although used goods create competition for new goods, a manufacturer would bene…t from a well functioning used-goods market increasing the willingness of consumer to buy new goods easy to resale. At the same time, the producer could slightly reduce the durability (by under investing in durability, by directly reducing new units durability, by introducing frequent style changes and new products...) : it alters the substitutability of new and used market and allows the …rm to increase the price of new units. The maintenance market could also interfere. Rust (1986) argues that, in case of a competitive maintenance market and a monopolistic new market, most of consumers would prefer over maintained used goods. Durability could have a positive impact on prices for both new and used market by increasing the quality of cars and therefore the utility of the consumer. At the same time, it has a negative impact on prices in the new market by improving the competition with the second-hand market. In the US market, by the beginning of the nineties, Peach and al (1996) observed that cars reliability, survival rate, and warranties durations have been rising simultaneously with car prices. Acknowledging that durability has not been the only factor impacting the level of price, graphical analyses show similar trends, from 1990 to 2008, of the median age and the average sale price of new cars. But their conclusions have to be strongly quali…ed : for used cars and light truck markets, similar trends are less visible12 . Furthermore the Consumer Prices Index for cars (new and used), that adjust prices through obsolescence and representative constant mixes of vehicles, has been decreasing since 1990 in the US13 . A third large area of research on durable goods discusses the Time inconsistency. Optimal 12 13 See graphs in Appendix 2. See graphs in Appendix 2. 88 CHAPITRE 3. A FAMILY HITCH durability and the Time inconsistency problem are embedded. According to Coase (1972) a monopolist has to manage the dilemma that the price of units sold in the future will be a¤ected by the characteristics of the units sold today. The Time inconsistency constitutes an issue for producers across planned obsolescence, R&D, and the introduction of new products on the market. Waldman (1996) argues that R&D could have a negative impact on new products because consumers expect a technological improvement in a later period. As a consequence, a monopolist should under invest in R&D and reduce the availability of the used goods (i.e. by reducing the durability of new unit, by repurchasing and scrapping the used units...) to maximize his pro…t. On the other hand, Fudenberg and Tirole (1998) argue that new and used units could become imperfect substitutes after the improvement of new goods. They conclude that R&D could have a positive impact on new goods prices, as well as a negative impact on second-hand cars14 . As already mentioned, microeconomic studies usually make the strong assumption of a monopolistic market. But Schiraldi (2009) proposed a microeconomic model in an oligopolistic car market. She concluded on a possible collusion of manufacturers to increase prices on second-hand markets through leasing policy, warranty policy and buy-back policy in order to increase prices on new markets. By and large, microeconomic results lead to various conclusions, but they always bring the idea that new and used markets impact each other prices (and volumes) on a short and a long time perspective. 3.2.4 Scitovsky’s mechanisms are part of a Keynesian framework. Most of mentioned articles assume a neoclassical economy driven by real factors and where money supply has no impact. Agents are optimizing their purchase and know the function to optimize. Scitovsky (1994) adopts a Keynesian approach that includes uncertainty and the impact of disposable incomes on the overall economy. Scitovsky investigates the destabilizing impact of secondary markets on the overall economy. They strengthen both recessions and recoveries. He …rst focuses on speci…c movements of prices : 14 Petrin(2002)’s empirical analysis on the impact of introduction of the minivan in the US market does not include the second-hand market, but the study con…rms the positive impact of innovation in a competitive market. When automotive …rms are introducing new products, they are cannibalizing each other pro…ts ignoring the externalities they create. In the end, new products can bring large pro…ts to the innovator and substantial gains for the consumer. 3.2. ACADEMIC RESEARCHES IN THE SECOND-HAND MARKET ARE LEGION. 89 consumers often react to a modi…cation of their income by shifting their demand between new markets and cheaper secondary ones. As a result, in case of a su¢ cient elasticity of goods substitution, new and second-hand markets become interdependent. A shock or a disequilibrium in each market impacts prices, demand and supply in the same direction. Additionally, both markets o¤set one another. The disturbed market excess demand (or supply) becomes equal to the other market excess supply (or demand) and prices are stabilized accordingly. Unfortunately, prices are stabilized only for a while. A gap between demand and supply still exist in both markets and an opposite e¤ect soon appears because of a slow adjustment of stock in the second-hand market. In the automotive sector, for instance, owners of used vehicles are more or less willing to hold their vehicles according to increases and decreases of prices. The slow variation of stock has the following consequences : the used market volume rises and reduces the level of price in the new market. So the interdependence disrupts the equilibrium in both markets. To summarize, following disturbance disequilibrium in one market, a short-term e¤ect of arbitraging creates a temporary obstacle to price movement and a move on the other market on the same direction. Then, on a second period, the second-hand market’s disequilibrium slowly liberates constraints of an equilibrating price movement. Scitovsky extends the discussion to the impact on the overall US economy. The e¤ect depends of the size of the used market. It depends also on the length of time the secondary market is able to compensate the variation of the new market without impacting prices. Automobiles are exceptional durable goods because of the size of the second-hand market, but Scitovsky assumes that the in‡uence of stocks would be limited to two months only15 (Car owners are rarely relinquish and dealers stocks are quite limited). From an empirical perspective, Peach et al (1996) also conclude that used markets intensify economic cycles. But they have another explanation : there has been a long-term shift of the US consumer demand from new to used car markets16 . Franchised new car dealers have captured 15 According to Scitovsky, …nancial assets are the only exception. The destabilizing impact of …anacial se- condary market would have no limit. Their sizes and shocks duration would signi…cantly impact the overall economy. 16 There has been a shift, as mentioned in the previous section, consequently to an increase of durability and 90 CHAPITRE 3. A FAMILY HITCH much of the second-hand market growth. They are collecting most of their pro…ts from used cars and are less aggressive bidders on the demand side of auctions. Regarding the supply side, when demand for new cars increases, they accelerate the used car price reduction by sending more used cars to auctions. The mechanism become reversed when the demand for new cars decrease. At the end, car markets have more volatility. Pashigan (2001) observed that US used car prices index has much more volatility than the new car index. The supply curves are less elastic for used than for new cars and, as a consequence, contribute to a higher volatility. 3.2.5 There are implied mechanisms behind the academic theories. Other mechanisms do not come from a speci…c literature and are implied in the previous contributions. We mention them for clari…cation purposes and to facilitate their identi…cations in the econometric analysis that will be implemented in the next section. "The new market feeds the used market" : as a result, volume and prices of today’s used car market might be positively correlated with volume and prices of the past new market. The mechanism also interacts with renewals on the used and the new markets. "Renewals" : after some years, drivers have to renew their vehicles. Concentrations of renewals create cycles on both markets. Additionally, concentrations on the new market could create future concentrations on the used market. "Volume e¤ect" : an increase of transaction volumes, if caused by a greater o¤er, could have a positive impact on the prices. An increase of transaction volumes, if caused by a greater demand, could have a negative impact on the prices. "Price e¤ect" : a price increase could have a positive impact on the volume of transactions by improving o¤er, or a negative impact by decreasing demand. "Arbitration" : a driver can buy a car on the used market or on the new market. A car bought from one market cannot be bought from another market at the same time. When most a¤ordability of cars, as well as a higher level of available information for consumers. 3.3. THE MACROECONOMIC TIMES SERIES NEED CLARIFICATIONS. 91 of drivers choose to buy used vehicles, volumes (and prices) improve in the used market and, as a consequence, decrease in the new market. "Reallocation" : when prices are too high in the new market, the buyers move to the secondhand market. Consequently, used car prices increase. In other words, prices and volumes move in the same direction in both markets on a short term perspective. Scitovsky analyzed the reallocation mechanism by insisting on the threshold e¤ects (due to stocks) on volumes and the lags creating constant disequilibrium. The "Income e¤ect" : a decrease of income (or consumption or con…dence) creates a decrease of demand, a decrease of transaction volumes, and a fall of prices in both markets17 . Alternatively, it could create a shift of consumption from the new market to the used market. As a consequence, volumes and prices go down in the new market while they are increasing in the used market. 3.3 The macroeconomic times series need clari…cations. We aim to check the accuracy of the mechanisms mentioned in the previous sections using econometric tools. The interactions of the consumer price indexes and the volume of transactions of new and second-hand cars are analyzed in three countries. Following an interpretation of the relations between the academic theories on durables goods and the time series behavior, we de…ne the limit of our macro-economic perspective. 3.3.1 Three countries are compared through four time series. We study the automotive markets of France, the United Kingdom and the United States of America. We consider observations related to the Consumer Price Index (CPI) and the volume of registrations (or sales) for new and used cars18 . The US volumes make the di¤erence : in 2007, used car sales volume was more than 41,4 millions for the US market. By comparison, it 17 18 According to Scitovsky (1994), the Income e¤ ect causes cycles. See Appendix 1 for data sources. 92 CHAPITRE 3. A FAMILY HITCH was 5.3 millions and 7 millions for France and the UK. Moreover, the passenger car populations in use for France, the UK, and the US were 30.7 millions, 30.1 millions, and 135.4 millions19 . We aim to analyze the interdependence between primary and secondary markets on a macroeconomic perspective. The quality of the car (to account for the Akerlof e¤ect), informations regarding demand (i.e. consumer con…dence) and o¤er (i.e. business con…dence), the level of R&D (for the Time inconsistency), the mix of vehicles or the level of stocks constitute relevant explanatory variables. However, we only included four time series in our analysis (prices and volumes) because of the di¢ culty to collect standardized information and to allow a comparison from a country to another. The National Statistical Institutes (INSEE for France, ONS for the UK, BLS for the US) provide the automotive Consumer Price Indexes. They re‡ect the general movement of prices on the new and the used car markets. The statistical institutes do not communicate a precise list of the items included in the samples used to construct the indexes. And the precise locations, where the observations are collected, are neither provided. They communicate, however, a general setting of their methodologies20 . The frameworks are not always similar from a country to another, but share the same objectives. First, the CPI has to re‡ect the cost of life and to give an overview of price variation of the general expenditure across the country. Then prices are collected from various areas and the selected samples of cars aim to be representative of what people buy in these areas. Second, although goods and services are changing through time in their characteristics, the statistical institutes intend to measure the e¤ects of price changes by keeping constant the other economic factors. The processes by which prices are adjusted to account for changes in product quality constitute an important subject of research and discussions in the automotive sector. The US applies the Grilitch methodology21 for the quality adjustment of automotive observations : the Hedonic approach estimates the price of a 19 The number of new passenger car registrations in 2007 for France and UK was 2.0 millions and 2.4 millions. New vehicles sales in US were more than 13,6 millions. The average car age is 8.1 and 6.7 years for France and for UK. In US, the median age for automobiles is 9.2 years. See data sources in Appendix 1. 20 See Caillaud (98) for France See www.statistics.gov.uk/articles/nojournal/CPISQR.pdf for UK. See Reinsdorf and Triplett (2008) and also Pashigan (2001) who provides critical elements on the US CPI for used cars. 21 See Otha and Grilitch (1976) for additional details the Hedonic methodology in the automotive area and also Fixler et al (1999). See Prado (2009) for an application on the European used car market. 3.3. THE MACROECONOMIC TIMES SERIES NEED CLARIFICATIONS. 93 good through the valuation of its attributes. France and the UK apply another methodology, the ’option costing’, that can be used when a product changes in speci…cation and when it is possible to value separately the components that have changed. We use the volumes of registrations (for France and the UK) and sales volumes (for the US) as proxies of the total amount of transactions. They do not allow a distinction between the variations of o¤ers and the variations of demands, and provide a slightly more ambiguous information than the CPI : an increase of sales could be either the consequence of an increase of demand, or an increase of o¤er, or a reduction of prices. The impacts of volumes on prices are also ambiguous. An increase of the volumes could cause either a reduction or an increase of prices. Following an improvement of the market size, for instance, the dealers could reduce their prices in order to increase their market share or to reduce …xed costs. They could also consider a high level of demand as an opportunity to improve their bene…ts by increasing prices. 3.3.2 How to connect the academic literature with a time series analysis ? We divide the economic literature, surveyed in Section 2, in three groups : the advanced mechanisms (Table 1), the Scitovsky theory (Table 2) and, the basic mechanisms (Table 3). Their consequences on the time series analyzed in our article are synthesized in the column ’Impact on Prices and Volumes’. The arrows ( =) () ) indicate that a parameter a¤ects or causes another one. In order to avoid any misunderstanding, we have to mention that we do not assume mechanical relations similar to a clockwork (or deterministic links), but we expect to identify probable interdependence between the new and the used markets (or stochastic links). 94 CHAPITRE 3.

A FAMILY HITCH As discussed in section 2.2, the new market could experience di¤erent consequences from the Akerlo¤ e¤ect. Therefore we made a distinction between the Akerlo¤ e¤ect 1 having only an impact on the used market and the Akerlo¤ e¤ect 2 impacting both markets. There was a similar issue with the Income e¤ect driving both markets in the same direction or in di¤erent ones. Another roadblock exists regarding the e¤ect of demand. As an example, for the Time inconsistency e¤ect, an increase of demand would create either an higher volume of transactions, or only an increase of prices, or both22 . The Akerlo¤, the Optimal durability and the Time inconsistency e¤ects are di¢ cult to investigate because they involve additional information (quality, durability, R&D...). They could be invalidated, however, when series move in di¤erent directions than the ones listed in the tables. For instance, the improvement of quality in the Akerlo¤ e¤ect would take some time to spread across the population of cars and therefore could be identi…ed by an increasing trend on volumes, or prices, or both. If the trends are decreasing, then the theory should be refuted. Our attempt to translate the theoretical economic literature under an econometric analysis highlights a critical point : the timing. In most of academics papers, except the Scitovsky (1994)’s article, the period in which the mechanism has an e¤ect was never explicit and the lags are not precisely de…ned. For instance, are the adjustments simultaneous in the Arbitration e¤ect ? Or are they lagged ? Do they last for the next six months ? Do they last for a year ? The econometrics of the next section will provide an insight on timing. 3.3.3 We work on macroeconomic time series, a limited information. The macroeconomic perspective presents four limits : the cross border sales, the availability of the historical observations, the usual critics on Consumer Prices Indexes, and the heterogeneity of the markets. As a …rst concern, the cross border sales might a¤ect the national prices and transactions of cars : the imported vehicles, for instance, could increase the competitiveness and reduce car prices. In the European market (including France) the existence of signi…cant cross bordering 22 It is identi…ed every time there is an "and/or" in the table. 3.3. THE MACROECONOMIC TIMES SERIES NEED CLARIFICATIONS. 97 transactions should lead to a price convergence. Gaullier and Haller (2000), however, did not notice mechanisms creating an automobile price convergence in European countries. They argue that exchange rate ‡uctuations explain a large share of the price dispersion dynamics23 . Parities between Euro-land countries were …xed in May 1998, so their study was too early to assess the long-term e¤ects implied by the implementation of the single currency. Prado (2009), through an Hedonic analysis on the 2005-2009 period, shows that even with the Euro implementation, distinct national markets still constitute the European second-hand car market. Thanks to the right wheel vehicles, we have few concerns for the UK market regarding a possible interaction, on prices and volumes, with the other countries. As a conclusion, the impact seems limited for France and the UK. The US car market has a size dramatically higher than the Mexican and the Canadian markets and we also expect a limited cross bordering impact. As a second concern, we have to keep in mind that our results might be altered by the limited period of available observations. All in all, knowing that cars longevity can run up to 20 years, the study would hardly provide a long-term perspective. In France, the used car CPI is available since January 1998, while, in the UK, the used car Index is available since January 1996. In the US, the BLS has published the used car index since 1952 and, in order to re‡ect the cost of living of a representative household, light truck vehicles have only been included in the CPI since 1998. To standardize the analyses (for the UK), for consistency purpose (for the US), and to allow a comparison of the three countries, we selected the CPI samples from January 1998. Regarding the times series of volumes (number of registrations, number of sales), we did not apply the same criteria for the selection of the period : we included as much information as possible, regarding the number of registrations and sales, maximizing the opportunity to identify a relation between prices and past volumes (i.e. correlation between used cars and previous …ve years used cars sales). Most of the time, the volume of transactions has been included according to the series provided by the statistical institutes and, as a result, series of volumes are longer than CPI series24 (except for the UK used car registrations). The time series for France, the UK and the US are presented in Appendix 3. The relevance of the variables constitutes our third concern. Like any other statistical indi23 24 They con…rm the conclusion of Goldberg and Verboven (1998) that prices follow exchange rates closely. France : New registrations and used car registrations since January 1987. UK : New registrations since January 1987/ Used car registrations since January 2001. US : New sales since January 1987/ Used car sales since January 1997. 98 CHAPITRE 3. A FAMILY HITCH cator, the Consumer Price Index has been the subject of several critics. In addition, because of the political and economical impacts on citizen (i.e. wage negotiations), there has always been a suspicion regarding the CPI accuracy. Two main critics show up : in the automotive area, people complain that Hedonic adjustments over de‡ate the movement of prices and that CPI does not re‡ect their ’feeling’of increasing prices. Greenlees and McClelland (2008) discussed the limits of those critics. They demonstrated the limited impact of Hedonic adjustment on CPI results25 . And a well known psychological ’loss aversion’could increase the sensibility to increasing prices than to decreasing prices ; because the CPI cannot re‡ect the consumption of a particular group of customers, they are de…ned as an average of the in‡ation rate. Consumers are always members of a speci…c group and they always have the feeling that the CPI is not in line with their speci…c consumption. Fourth, speaking of di¤erent groups of customers, we have to clarify that, although we work at a country level, we do not assume heterogeneity of the markets : a national car market could be the sum of several sub markets involving very di¤erent populations of customers. A sub market might strongly impact the whole car market through a signi…cant size or a high level of volatility. But we aim to provide a macro-economic perspective and intra market interactions do not constitute the subject of our study. 3.3.4 What do the series look like ? The period of analysis has been standardized from January 1998 to June 2009. The French market seems rather stable, whereas the UK26 and the US prices follow a negative trend and display a high volatility27 . For the last ten years the trends of the US series look negative and illustrate the crisis of the automotive sector in North America. All these characteristics remain through a growth rate perspective and after a seasonal adjustment28 . 25 Although there is no European study that would corroborate these results, we also assume a limited impact regarding the quality adjustment methodologies applied on the French and the UK Consumer Price Index. 26 For UK, they are two big variances after 1999. There has been a change in the car registrations process after 1999. Prior to 1999, new plates were introduced in August. From 1999 onwards, there has been two plate changes, in March and September. 27 See graphs in Appendix 3. 28 Series are seasonally adjusted using X11 methodology. See graphs in Appendix 4. 3.4. THE ECONOMETRIC ANALYSIS SHOWS DIFFERENT RESULTS BY COUNTRY.99 At a glance, new car CPI are always more stable than used car CPI. Prices on the used market are the result of demands and o¤ers, while new car prices are set by the dealers and manufacturers according to constraints of production and maximization of pro…ts. If new car prices become too high, the number of sales decreases because of prices rigidity on the new market and the adjustment operates mainly by the volume of transaction29 . As a result, registration (or sale) volumes are more volatile for new cars than second-hand cars, and new car prices are quite stable. The market readjustment through volumes explains why some economic institutions (i.e. OECD) use new car transactions as a short-term economic indicator. In contrast, prices in the second-hand market are set through o¤er and demand. As a result, used car prices display more volatility than new car prices. By the beginning of 2008, the time series falled sharply. The subprime crisis, a global economical event, appears as an opportunity to compare the reaction on the di¤erent markets and to con…rm the previous statements. The new cars registrations (or sales for the US) are more impacted (by a stronger drop) than the used car registrations (or sales), and used car CPI is more impacted than new car CPI. As a …rst conclusion, it suggests that, in the case of an Income e¤ect, the used car market has an higher probability to be impacted on a price perspective, whereas the new market would rather be impacted on a volume perspective because of a relative price rigidity from car manufacturers. The mechanisms mentioned as the Feeds e¤ect, Arbitration, Prices e¤ect and Volume e¤ect might be similarly a¤ected. All in all, new car markets in the UK and the US have been declining for the last 10 years, while France has been a stable market. 3.4 The econometric analysis shows di¤erent results by country. The econometric tools identify trends, cycles and correlations through various durations (short-term, very short-term, the whole ten years period). At the same time, we evaluate if the 29 These conclusions should be con…rmed by an analysis of the automotive production (does the manufacturers adjust the production according to prices ?) and stocks available (how the stocks impact the markets ?). 100 CHAPITRE 3. A FAMILY HITCH outcomes are in line with the academic theories. At the end of the section, we estimate the VAR models to investigate the relations between the markets and the possible forecasts30 . 3.4.1 The unit root tests undermine the advanced mechanisms. As previously stated, France appears as a stable market. To check this intuition, we apply the Augmented Dickey Fuller unit root test to the growth rate of the series. The results are reported in Table 4 and show that the French volumes and index prices have been stationary for the last ten years. On the contrary, the UK and the US have trends : new cars CPI in the UK, as well as the volume of new car and used car sales in the US, have a unit root (Di¤erence Stationnarity or DS). According to the econometric theory, it means that a macroeconomic shock would have an impact on the trend series forever. In contrast, a trend stationnarity (TS) has been identi…ed for the new car prices index in the US, implying that a macroeconomic shock would have a temporary e¤ect on the prices. Finally, the used car CPI has no trend in every country.

THE ECONOMETRIC ANALYSIS SHOWS DIFFERENT RESULTS BY COUNTRY.101 The unit root test invalidates the assumption that, for the last ten years, prices and volumes have been moving in the same direction in the UK new car market (the new car CPI follows a DS process while the volume of used car sales was stable), and in the US new market (sale volumes and prices follow a di¤erent trend, a TS and a DS). Turning to the economic theories, it rejects the presence of mechanisms involving similar long-term trend on prices and volumes (like the Akerlo¤ e¤ect, the Time inconsistency....). As an example, the decreasing trend in the US might be explained by the Optimal durability e¤ect : the demand for vehicles decreases because cars durability has improved. Drivers do not have to renew their vehicles as often as in the past. An improvement of cars quality should also lead to an expansion of the secondhand market, and in the same manner, an increase of used cars prices (and volumes). But the Optimal durability mechanism is invalidated by the stationnarity of the used car prices (and the decrease of used car volumes). Focusing on car prices, the estimated trends refute several mechanisms and illustrate the absence of a long term relation between prices. The stability in France and the trends moving in the same direction in the UK invalidate the existence of a strong Akerlo¤ e¤ect 2, or an Optimal durability e¤ect. Regarding the sale volumes, the trend analysis on the whole period illustrates the well known fact that the new cars of today are the used cars of tomorrow. In France and the UK, the new and the used car registrations share a similar stationnarity. In the US market, a cointegration test identi…es a common long-term trend between new car and used car sales31 : for the last ten years, the new and used US sales have been declining. These results also weaken the mechanisms reported in Table 1. It is highly unlikely that the stability in France and the UK, as well as the decline in the US, would be due to a global decrease of cars quality32 (according to the Akerlo¤ e¤ect, the Time inconsistency....). 31 See cointegration test details in Appendix 9. The construction of an Error Correction Model (ECM) including the US volumes series did not provide a good adjustment. As a result, the model did not constitute a useful tool to forecast the volumes and we did not keep it in the study. Moreover, the US market only has two identi…ed Di¤erentiated Stationnnarity (DS) time series. As a consequence, there is no possibility of a cointegration test and an ECM for France and the UK. 32 We can’t believe, as well, that it would be due to a decreasing quality of information available for buyers. 102 CHAPITRE 3. A FAMILY HITCH 3.4.2 The correlation analysis provides a one-month period perspective. The correlation calculation provides a …rst insight on the simultaneity of market evolutions33 . For France, a negative correlation between new CPI and used CPI suggests an arbitrage on prices (i.e. when prices decrease on the new market, they improve on the used market). The signi…cant correlation between new and used registrations has a positive sign that might be caused by an Income e¤ect on the volume of transactions. In other words, when drivers incomes (and demand) improve, the volume of sales increases on both markets. For the UK, there is a positive correlation between the new car registrations and the used car prices. These results are in line with the graphical analysis : Market adjustments are made through new volumes and used prices whereas constraints exist on new car prices and on the volumes of used car transactions ; following an economic crisis, new sales and second-hand prices fall sharply while new prices and second-hand volumes remain relatively stable. For the US, a strong positive correlation exists between new and used prices (r = 0:54) as well as a negative correlation between new and used transactions. The US market dynamics are converse to the French ones ; it suggests an Income e¤ect on a price perspective and an Arbitraging e¤ect on a volume perspective. These results evoke a Scitovsky’s framework : in the new and the second-hand markets, prices move in the same direction but the variation of bid, o¤er and stocks in both markets lead to a constant disequilibrium. 3.4.3 The Granger causality tests elaborate the assessments of the correlation analysis. To investigate the interdependence between new and used car markets, we …rst apply the Granger causality test34 evaluating how much the previous six month information contained in 33 Details are given in Appendix 6. The econometrics tools are applied on the seasonally adjusted growth rates and stationnary time series. 34 The Granger test has been set with six months lags. 3.4.

Table 5 : Granger test Results. In the French market, new and used cars registrations are interrelated : the null hypothesis, that the volume of used car registrations does not Granger cause the volume of new car registrations, has not been rejected at the 5% signi…cante level. In addition, the volume of new car registrations Granger causes the volume of used car registrations35 . It con…rms the Income e¤ect mentioned in the correlation analysis. Furthermore, the Granger test indicates that the used car CPI helps to predict used car registrations and new cars registrations : rising used car prices improve drivers willingness to resale their cars and to buy a new one, as a result, the number of registrations goes up. For the UK, the used car CPI helps also to predict new cars registrations. The results corroborate the graphical and the correlation analyses and emphasize that the adjustments on the new market are more on volumes than on prices. Nevertheless, it seems that dealers and manufacturers try to adjust prices and volumes according to the state of the market, because new car registrations and new car prices also help to predict each other. 35 See the detailed Granger test results in Appendix 5. 104 CHAPITRE 3. A FAMILY HITCH The causalities are more numerous in the US market : new car prices and used car prices help to predict each other ; new car sales and new car prices help to predict used sales ; at the same time, the new car sales help also to forecast new car prices. The test suggests the existence of multiple relations between new and second-hand cars and shows a strong interdependence in the US markets by comparison to France and the UK. To be speci…c, the Scitosky’s theory, of constant disequilibrium from one market to another, constitutes a possible explanation. 3.4.4 The Hodrick-Prescott …lter reveals economic cycles. In order to identify long-term trends of the series, we calculate Hodrick-Prescott …ltered series36 . The …lter produces a smoothed non-linear representation of the time series that is more sensitive to long-term than to short-term ‡uctuations37 . For France, the graphs show larger cycles (of 2 years) for used car prices index by comparison to new car prices (6 months) and the volume of transactions. Similarly, second-hand price follows a longer and more visible cycles in the UK and the US car markets. The distinct pattern of the used car prices mitigates the validation of mechanisms involving prices and volumes moving in harmony (Akerlo¤ e¤ect, Time inconsistency). We evaluate the synchronizations of prices and volumes ‡uctuations. Following Fiorito and Kollintzas (1994), we measure the degree of co-movement of the series’ cyclical components through the correlation coe¢ cient . If the correlation between the cyclical components of two series is positive, null or negative the series cycles are identi…ed as procyclical, acyclical, or countercyclical. If 0:1 j j < 0:23 or 0:23 j j < 1:0 the cycles are classi…ed as weakly correlated or strongly correlated. We also calculate (j) with j 2 f 3; 6; 9; 12; 24; 36g in order to identify lagged correlations. We report the strong correlations38 on Table 6. 36 37 See HP …lter cycle and trend graphs in Appendix 7. The sensitivity of the trend to short-term ‡uctuations is adjusted through a multiplier . From an Empirical perspective the suggested is equal to 14,400 for monthly data. See Hodrick and Prescott (1997). 38 The complete results are reported in Appendix 8. 3.4.

The …lter, applied to the French car prices series, allows the assumption of a Feed e¤ect : there is a 36 month pro-cyclical movement of new prices with used prices39 . The new prices of the past 36 months impact the second-hand prices of today. Furthermore, the …lter indicates a critical correlation between new cars and used cars registrations40 : the cycles of new and second-hand transactions increase and decrease simultaneously. As a result, like the correlation 39 40 = 0:34 = 0:42 106 CHAPITRE 3. A FAMILY HITCH analysis of Section 4.2, the Hodrick-Prescott …lter identi…es an Income e¤ect on a volume perspective. On the UK market, the …lter also con…rms the existence of a Feed e¤ect : used car prices cycles are pro-cyclical to new car prices through lags of 3 to 12 and 36 months41 . The absence of strong correlations on registrations cycles with other series reduces the probability of a Scitovsky mechanism. For the US, markets cycles are well interrelated. There are several pro-cyclical and countercyclical relations between prices and volumes. First of all, we identify a positive correlation between new car CPI and the used car CPI. In addition, the used car CPI, with 9 months and 12 month lags, appears countercyclical to the volume of used sales. Finally, the used sales volumes have a cyclical relation with new car prices. These results are in line with the Scitovsky theory. 3.4.5 Vector Autoregressive (VAR) models clarify the previous results. A Vector Autoregressive model gives a straight perspective of the relation between prices and volumes in both markets. We selected the best model using the Akaike and the Schwarz criteria. The results are reported in Appendix 10 and show the usual greater interaction between the primary and the secondary markets for the US. Let us discuss the outcomes for each country. For France, the used car prices mainly depend on their own lagged values42 . The equation is in line with the Hodrick Prescott results displaying that used CPI cycles are di¤erent to other series cycles. For the new car prices equation, the model has a good …t to the data thanks to the relevant information from the previous month new prices and the constant. These results corroborate the graphical analysis revealing rigidity of new car prices by showing few ‡uctuations of the new car CPI. 41 42 At the same time, new car prices with a lag of 3 to 12 and 36 months are counter-cyclical to used car prices. Previous months of used CPI variables have a high statistical signi…cativity according to the student test. 3.4. THE ECONOMETRIC ANALYSIS SHOWS DIFFERENT RESULTS BY COUNTRY.107 Regarding the French volume equations, the new and the used cars registration models have a poor adjustment to the historical observations and none of the variables are statistically signi…cant. In other words, none of the variables from one market are relevant to model the other market, and the VAR methodology does not identify the suggested relations of the previous section (correlation and arbitraging). Gautier (1995) attempted to identify new car registration cycles, which would be a characteristic of durable goods in the French market since 1945. He concluded that registration cycles are more the result of the economic activity (with additional volatility and sectorial events) than to the internal dynamics of car markets. It means that, in order to forecast the registrations in France, a model including variables related to the economic activity would be more relevant. For the UK, the used car CPI equation shows that, in a similar way to France having distinct cycles for used car CPI, the previous months used car prices information is statistically signi…cant. The new market variables are also crucial, but they have smaller coe¢ cients compared to used car prices lagged values. To be more speci…c, the coe¢ cients of the variables from the new market have a positive e¤ect and therefore reinforce the conclusions of the graphical and the correlation analyses (the new CPI coe¢ cient is less important because of the rigidity of new car prices created by production constraints), as well as the Granger causality test (in spite of the rigidity, dealers try to modify the prices according to the state of the economy). Regarding the new cars CPI equation, although the adjustment is poor, two variables appear signi…cant (the used car price index and the used car registrations). But even with a new car CPI series positively correlated to the used car market, the weakness of the relation suggests that any involved mechanism would be quite limited. For the British used cars registrations equation, the model has also a poor adjustment and registrations seem slightly and positively impacted by the used car prices : when prices go up, dealers and privates get an opportunity and they increase the volumes of sales, but stocks are limited and the evolution remains limited as well. Into the new cars registrations equation, though the used cars CPI and the constant constitute the only relevant information, the model adjustment is quite good. Again, it strengthens the previous conclusions that economic readjustments are mainly made on the new market by volume (and on the used market by price) : when the state of the economy improves, for instance, the volume of new cars and the prices of used cars react …rst and increase. The new car volumes are, however, limited by production 108 CHAPITRE 3. A FAMILY HITCH constraints and consequently, the constant in the equations appears highly signi…cant. The positive coe¢ cient of the new car volume variable would only allow the existence of mechanisms with similar co-movements in both markets (Income e¤ect, Akerlo¤ e¤ect...) on a short period. From the previous results in the US market, we know that the used CPI follows speci…c cycles and, at the same time, was positively correlated to new car prices. Accordingly, in the used CPI equation, the lagged used car prices and the new car CPI (with a positive sign) are statistically signi…cant. On the contrary to France and the UK, the new CPI equation is well …tted to the historical observations. New car prices are explained by the previous used car CPI and the previous new CPI. They are also positively impacted by the volume of transactions of the new market. Therefore the US car prices are connected in various ways with the new and the used market. The explained variance of US volume equations are not as good : R2 are equal to 20% and 47% for new and used sale equations. In the new sales equation the only important variables are the previous new sales ; in the used sales equation the new and the used sales are signi…cant variables. Scitovsky (1994) mentioned that the market adjustments were altered by the limited variation of volumes. He argued that used car market volumes were limited by stocks. In addition, we argue that new car volumes are limited by production constraints, and that the VAR results on volumes are fully in line with his theory. 3.5 To conclude, an interdependence ? To conclude, what kind of interdependence exists between the new and the second-hand car markets ? The aim of this chapter was to investigate the interdependences between the new and the second-hand car markets in three countries : France, the UK and the US. The analysis was limited to a ten year period ; since cars are durable goods that can be used for more than 20 years, it might have restricted the results to interdependences shorter than a decade. The econometric tools, however, show consistent outcomes all along the study. Results are synthesized in Tables 7, 8, and 9. 3.5. TO CONCLUDE, AN INTERDEPENDENCE ?

Table 9 : General Results on Basic Mecanisms. Initially, we argue that in all countries the new market of the past is linked to the used 110 CHAPITRE 3. A FAMILY HITCH market of today, through volumes and prices. Secondly, the interrelations appear limited for France and the UK, whereas the US market is characterized by a Scitovsky dynamics, de…ned by constant disequilibrium and multiple interactions between primary and secondary markets. Our contribution also highlighted that, depending of a short-term or a long-term perspective, interactions are di¤erent. Thirdly, theories implying volumes and prices moving in the same direction (Akerlo¤ e¤ect, Optimal durability, Time Inconsistency) are di¢ cult to con…rm. Finally, for France, the UK, and the US the connections between primary and secondary car markets are not similar, but all markets experience a characteristic rarely mentioned in the literature : a rigidity of both the new car prices and the used car volumes of transactions. Another similar characteristic is that, for all countries, used car prices follow distinct cycles. All things considered, our results illustrate that the interrelations between the new and used car markets are not strong enough to fully explain and forecast the market patterns. The use of macroeconomic variables related to the disposable income of buyers or the general state of the economy might improve the forecast accuracy, and is left for future research. 3.6.

A FAMILY HITCH Conclusion Générale Dans un contrat de leasing, le bailleur prend le risque de subir des pertes …nancières lors de la revente de l’actif. Il exite un risque de valeur résiduelle. L’objectif général de cette thèse est d’apporter une contribution académique à ce problème peu connu mais essentiel dans l’activité de leasing. La thèse traite des di¤érents outils d’analyse quantitative disponibles pour les départements de gestion d’actifs et couvre trois thèmes : la valorisation des équipements par la méthode des prix hédoniques, la couverture du risque de valeur résiduelle à l’aide de produits …nanciers dérivés, et en…n les relations macro-économiques entre le marché du neuf et celui de l’occasion. Les modèles statistiques de prix hédoniques ont été largement utilisés pour l’analyse du marché automobile. Dans le premier chapitre, nous exposons la méthodologie et proposons une application aux véhicules d’occasion dans le secteur du leasing, où la valeur résiduelle est un paramètre critique. Le modèle exploite les caractéristiques techniques des véhicules a…n d’estimer la distribution des prix de revente. Deux autres facteurs, pouvant in‡uencer le marché automobile, sont inclus : le prix du carburant et l’activité économique (l’indice de production industrielle). La méthodologie, appliquée aux marchés automobiles d’occasion dans quatre pays européens (l’Allemagne, l’Espagne, la France et la Grande Bretagne) fournit une perspective nouvelle. En se concentrant sur le comportement de dépréciation de deux véhicules (Ford Focus et Audi A4), notre étude révèle les di¤érents niveaux de probabilité de pertes en utilisant les informations de revente disponibles par les sociétés de leasing. A travers une analyse des prix et du risque, l’approche permet également d’identi…er les opportunités de leasing sur les di¤érents marchés. Notre première étude peut être poursuivie de plusieurs façons. L’industrie de leasing com133 134 CONCLUSION GÉNÉRALE prend tous les types de matériel et l’application de l’approche hédonique est su¢ samment ‡exible pour être étendue à d’autres actifs que l’automobile. En outre, notre analyse pourrait également être étendue aux contrats avec option d’achat ou avec une option dite de ‘rewrite’sur l’âge et le kilométrage (le client pouvant, à tout moment, choisir de prolonger ou d’interrompre le contrat.) Deux autres éléments dans le domaine du risque de valeur résiduelle pourraient être ajoutés pour compléter l’analyse : le cycle de vie du véhicule et la variation générale du marché. Les facteurs macro-économiques, en particulier, appellent à une étude plus approfondie. Dans le deuxième chapitre, le modèle des copules gaussien de Li, qui a initialement été utilisé pour l’analyse du risque de crédit, est transposé dans le secteur du leasing pour l’étude du risque de valeur résiduelle. Un nouveau produit dérivé est proposé, le Collateralized Residual Value (CRV). Le produit dérivé convertit les risques de pertes à la revente d’un portefeuille de leasing en un instrument qui peut être vendu sur les marchés …nanciers. A l’instar des produits dérivés classiques, il constitue un outil de transfert de risque. Ainsi il peut être utilisé à des …ns de couverture des risques ou de spéculation. En outre, il permet au bailleur et au locataire de choisir leurs degrés d’expositions au risque de valeur résiduelle et ainsi d’améliorer leur compétitivité. En conséquence, le modèle se présente comme un apport pour les professionnels de l’industrie du leasing intéressés par un produit …nancier novateur, ainsi que les acteurs des marchés …nanciers intéressés par de nouvelles possibilités d’investissement. Notre seconde analyse peut être étendue de diverses manières. La précision des composants du modèle pourrait être améliorée, notamment par une analyse macro-économique du paramètre de corrélation. En…n, d’autres familles de copules pourraient être appliquées. Dans le dernier chapitre, nous étudions les interdépendances entre les marchés de véhicules neufs et de véhicules d’occasion dans trois pays : la France, le Royaume-Uni et les ÉtatsUnis. L’analyse porte sur une période de dix ans. Les interactions sont donc étudiées sur une décennie, alors même que l’automobile est un bien durable avec une durée de vie qui peut aller jusqu’à 20 ans. Pourtant, les outils économétriques montrent des résultats uniformes tout au long de l’étude. Nous constatons que pour les trois pays étudiés, le marché du neuf et le marché de l’occasion interagissent par les prix et les volumes. Cependant, les interrelations semblent limitées pour la France et le Royaume-Uni, alors que le marché américain se caractérise par une dynamique dite de ‘Scitovsky’, dé…nie par un déséquilibre constant et de multiples interactions entre les marchés du neuf et de l’occasion. Notre étude a également révélé qu’en fonction de 135 la perspective de court ou de long terme, les comportements des marchés sont di¤érents et que certaines théories (Akerlo¤ e¤ect, Optimal durability, Time Inconsistency) impliquant des volumes et des prix variant dans la même direction sont di¢ ciles à con…rmer. Bien que pour ces trois pays les relations entre les marchés automobiles du neuf et de l’occasion ne soient pas identiques, ils partagent tout de même une spéci…cité rarement mentionnée dans la littérature : les prix pour les voitures neuves et les volumes de transaction des voitures d’occasion subissent des rigidités. Le fait que les prix des voitures d’occasion suivent des cycles distincts est un autre trait commun pour tous les pays. En…n les résultats montrent que les corrélations entre les marchés de voitures neuves et d’occasion ne sont pas su¢ samment fortes pour expliquer pleinement les variations des marchés. L’utilisation de variables macro-économiques liées au revenu disponible des acheteurs ainsi que l’état général de l’économie pourraient grandement améliorer la qualité des prévisions, et faire l’objet de futures recherches. 136 CONCLUSION GÉNÉRALE Bibliographie Bibliographie de l’Introduction Générale 1.
