Cournot tatonnement and potentials

Kukushkin, Nikolai S. (2014): Cournot tatonnement and potentials.

Abstract

We study what topological assumptions should be added to the acyclicity of individual best response improvements in order to ensure the existence of a (pure strategy) Nash equilibrium, as well as the possibility to reach a Nash equilibrium in the limit of a best response improvement path.
