Différenciation du produit et concurrence oligopolistique. Une étude du marché automobile français


  • Laurence Cecchini


[fre] Les modèles de choix discrets ont récemment été utilisés pour étudier les marchés de produits différenciés. Le modèle estimé ici associe des demandes définies par un modèle Logit multinomial emboîté à une offre oligopolistique dispensée par des firmes multiproduits ayant un comportement non coopératif. Une application est réalisée sur le marché automobile français. Nous déterminons les caractéristiques des produits et des individus qui influencent les achats et donc les parts de marché des véhicules. Nous proposons également des éléments d'analyse des effets générés par la prime à la qualité, qui était en vigueur en France en 1994 et 1996, ainsi que des marges des producteurs. [eng] Product differentiation and oligopolistic competition: a study of the French automobile market. Discrete choice models are now used to study the markets of differentiated products. The model presented associates demands defined by a nested multinomial logit model, to an oligopolistic supply offered by multiproduct firms ha ving anon cooperative behaviour. An application is performed on the french automobile market. We estimate the characteristics of the products and individuals which determine car market shares. We also propose some elements of analysis of the effects generated by government quality incentives, which was bind in 1994 and 1996, and of the producer margins.
