It focuses on the case of substitute goods, and allows for cost asymmetry between forms. The main finding is that, when the degree of cost asymmetry is sufficiently high and/or the degree of product differentiation is sufficiently low, equilibrium profits of the efficient firm and the industry profits are higher under price than under quantity competition. This contrasts with a standard result by Singh and Vives (1984), that is, with substitute goods both firms earn higher profits under Cournot than under Bertrand competition.Read More
