Spatial Cournot competition and transportation costs in a circular city

Abstract

We reconsider a Cournot spatial competition in a circular city. We discuss an oligopoly model. We find that two equilibria exist if the transport cost function is nonlinear in distance, while a continuum of equilibria exists if it is linear. Thus, the result of the real indeterminacy of equilibria in the linear transport cost case is knife edge.
