CAM Colloquium - Mike Todd: Computation, Multiplicity, and Comparative Statics of Cournot Equilibria in Integers
From E. Cornelius
We give an efficient algorithm for computing a Cournot equilibrium when the producers are confined to integers, the inverse demand function is linear, and costs are quadratic. The method also establishes existence constructively. We use our characterization to discuss the multiplicity of integer Cournot equilibria and their relationship to the real Cournot equilibrium.
