Différenciation des produits et structures de marché: un tour d'horizon

Abstract

This paper is a survey of some recent theoretical models related to the endogeneous determination of market structure in differentiated products industries. Usually, market structure is explained mainly by supply side characteristics such as economies of scale, economies of scope and sunk costs. These variables remain however exogeneous, which is incompatible with long term competition. Here, this view is contrasted with the one which emphasizes three aspects: the nature of product differentiation, the process of entry and choice of product, and the competition for sequential innovations.
