Abstract

[eng] A Survey of the Mixed Oligopoly Literature We present a survey of the literature on mixed oligopoly, defined as markets where a small number of firms are active and where firms with different objectives coexist. The main part of the analysis focuses on the competition between private, profit-maximizing firms and public, social-welfare maximizing firms. We show when the intervention of a public firm is welfare-improving, what the optimal share of public ownership in a partially private firm is, and what the objectives of a public firm, or of its managers, should be. We also study the competition between profit-maximizing and employee-controlled firms. We show how results differ according to whether the goods produced are homogenous or differentiated. [fre] Philippe De Donder L'entreprise publique en concurrence : les oligopoles mixtes. Cet article procède à une revue de la littérature portant sur les oligopoles mixtes, c'est-à-dire les marchés dans lesquels un bien ou service est fourni par un petit nombre d'entreprises qui n'ont pas toutes le même objectif. Les principaux objectifs étudiés sont la maximisation du profit et du bien-être. Nous présentons notamment les conditions sous lesquelles il est optimal d'avoir au moins une entreprise publique, la part optimale d'actions qui devrait être détenue par l'autorité publique dans une entreprise mixte, ainsi que les objectifs qui devraient être assignés aux entreprises publiques et à leurs managers. Nous étudions également la coexistence d'entreprises maximisant leur profit et d'entreprises autogérées. Nous contrastons les résultats obtenus quand les entreprises offrent des biens homogènes ou différenciés.
