Abstract

In a pure exchange economy we propose a general equilibrium concept under imperfect competition, the "Cournotian Monopolistic Competition Equilibrium", and compare it to the Cournot-Walras and the Monopolistic Competition concepts. The advantage of the proposed concept is to simplify the calculations attributed to strategic agents. Then we study the connexion of these concepts to a general concept of P-equilibrium which is extended to economies with production.
