''Cournot Equilibrium Uniqueness in Case of Concave Industry Revenue: a Simple Proof''
( 2015, Vol. 35 No.2 )
A simple proof of an equilibrium uniqueness result by Murphy, Sherali and Soyster for homogeneous Cournot oligopolies with concave industry revenue function and convex cost functions is provided. Adapting this proof, a substantial improvement of their result is obtained; the improvement concerns capacity constraints, non-differentiable cost functions and industry revenue functions that are discontinuous at 0.
Keywords: Concave industry revenue, Cournot oligopoly, equilibrium uniqueness
