Différenciation horizontale et verticale des produits: Une application à l'industrie automobile

Annals of Economics and Statistics, 1992, issue 27, 115-147

Abstract: We propose an oligopolistic competition model where exchanged products are simultaneously differentiated in horizontal and vertical dimensions. Perfect NASH equilibria are defined supposing that some decisions sequencies are expressed in terms of prices, technical characteristics and quality. In this context, it appears that horizontal differentiation is maximum at the equilibrium. Econometric estimations on panel data show a recursive prices determination of French cars sold on the national market and the importance of technical characteristics in the short and long run prices formation. Furthermore, these estimations prove that the market segmentation is realized from quality.
