Unicidad del equilibrio de Nash-Cournot con correspondencias de mejor respuesta contractivas
In this work we obtain new conditions to uniqueness of Nash equilibrium in the Cournot oligopoly model. These conditions assure that the reaction functions are contractions and they are not reduced to the obtained ones by Rosen, inasmuch as they do not demand the strict concavity of the bene¯t functions
