Résumé

La problématique de l'équilibre général en présence de concurrence imparfaite est examinée à l'occasion d'une vue d'ensemble de la littérature consacrée au sujet. On tâchera de souligner à la fois les apports et les limites de la théorie sur cette question, plus particulièrement dans la perspective d'aboutir à des « fondements microéconomiques de la macroéconomie » reposant de façon explicite sur les comportements imparfaitement concurrentiels des agents économiques.

Summary

Summary

This paper surveys the literature devoted to the problems of general equilibrium in imperfectly competitive economies. The achievements and shortcomings of the theory are emphasized, in particular with the prospect of providing «microeconomic foundations of macroeconomics» explicitly resting on the imperfectly competitive behaviour of economic agents.
