The Cournot-Bertrand model and the degree of product differentiation

Economics Letters, 2011, vol. 111, issue 3, 233-235

Abstract: We consider a duopoly model with a Cournot-type firm and a Bertrand-type firm. Both survive and the equilibrium is stable when there is sufficient product differentiation. With no differentiation, only the Cournot-type firm survives, and the outcome is perfectly competitive.
