Abstract

espanolUsando el coeficiente de cooperacion, analizamos el efecto de las asimetrias en costes en los acuerdos colusorios cuando las empresas son capaces de coordinarse en niveles de produccion distintos de aquel que maximiza el beneficio conjunto. En este contexto, primero investigamos en que medida son factibles los acuerdos colusorios. En segundo lugar, nos centramos en la sostenibilidad de la colusion en un juego repetido infinitos periodos. Se demuestra que, independientemente del grado de asimetria en costes, al menos cierto nivel de colusion siempre es sostenible. Finalmente, tambien se obtiene el grado de colusion endogeno para demostrar que la cooperacion tiene un limite superior determinado por la empresa mas ineficiente. EnglishUsing the coefficient of cooperation, we analyse the effect of cost asymmetries on collusive agreements when firms are able to coordinate on distinct output levels than the unrestricted joint profit maximization outcome. In this context, we first investigate the extent to which collusive agreements are feasible. Secondly, we focus on collusion sustainability in an infinitely repeated game. We show that, regardless of the degree of cost asymmetry, at least some collusion is always sustainable. Finally, the degree of collusion is also endogeneised to show that cooperation has an upper bound determined by the most inefficient firm.
