Cournot Markets

Posted by D. Daniel Sokol

Khadidja Benallou (UFR de sciences economiques et de gestion, Universite de Caen Basse-Normandie), Daniel Danau (UFR de sciences economiques et de gestion, Universite de Caen Basse-Normandie) and Abderrahmane Ziad (UFR de sciences economiques et de gestion, Universite de Caen Basse-Normandie) describe Cournot Markets.

ABSTRACT: This paper focuses on the existence of a Cournot equilibrium in a n- firm Cournot market for a single homogeneous commodity. Using a simple argument and proof, it shows that a Cournot equilibrium exists if each firm's marginal revenue declines with its own output and some weak non-decreasing incremental cost condition is satisfied.
