General equilibrium concepts under imperfect competition: a cournotian approach

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 require less computational ability from the agents. The comparison is made first through a simple example, then through a more abstract concept, theP-equilibrium, based on a general notion of price coordination, the pricing-scheme.Journal of Economic LiteratureClassification Numbers: D5, D43.
