ACCINELLI, Elvio  y  SANCHEZ CARRERA, Edgar J.. Unicidad del equilibrio de Nash-Cournot bajo correspondencias contractivas de mejor respuesta. EconoQuantum [online]. 2007, vol.4, n.1, pp.43-57. ISSN 2007-9869.

In this work we obtain new conditions to reach the uniqueness of Nash equilibrium in a Cournot oligopoly model. These conditions assure that the reaction functions are contractions and they are not reduced to the obtained ones by Rosen (1965), in as much as they do not demand the strict concavity of the benefit functions
