In this work we are concerned with static price games played by a given number of capacity- constrained firms producing a homogeneous commodity. The focus is mainly on capacity configurations in which either all firms are equal or all are so except a larger one and such that no pure strategy equilibrium exists. We show that in the former case the symmetrical solution is the unique equilibrium whereas in the latter a number of asymmetrical equilibria may also exist.
Keywords: Symmetric and asymmetric oligopoly, Bertrand-Edgeworth competition, mixed strategy equilibrium, symmetric equilibrium
