Stability of the Cournot equilibrium for a Cournot oligopoly model with n competitors

  • Lampart, Marek

Abstract

In this paper a Cournot-like model is constructed with an iso-elastic demand function for n competitors. The Cournot equilibrium is constructed for general constant unit costs. Finally, it is proved that for identical unit costs the Cournot point is a sink for two or three competitors and a saddle for more than four players.
