El número óptimo de empresas bajo competencia de Bertrand


  • Germán Coloma


Este trabajo es acerca de un modelo de competencia en precios en el mercado de un producto homogéneo con libre entrada de empresas idénticas y rendimientos variables a escala. Si el número óptimo de empresas activas en el mercado es dos o más, el equilibrio de Bertrand existe siempre para dicho número óptimo, y no existe si el número de empresas activas es menor que el óptimo. El modelo, sin embargo, no descarta la existencia de equilibrios con más empresas activas que el óptimo. Finalmente, si el número óptimo de empresas es igual a uno, entonces el equilibrio de Bertrand no existe.
