Abstract

En este trabajo se analiza el comportamiento competitivo de las cuatro principales empresas generadoras que operan en el mercado mayorista de electricidad español, centrando el análisis en la producción de sus centrales térmicas durante 2001. Los objetivos de este trabajo son: estimar si el comportamiento estratégico que adoptan dichas empresas se puede aproximar mejor mediante un modelo estático o mediante uno dinámico, que resulta de una interacción repetitiva que se da durante un periodo temporal indefinido; así como determinar si las empresas analizadas ejercen poder de mercado, en particular si compiten a la Cournot o con algún grado de colusión implícita. Los resultados obtenidos permiten extraer las siguientes conclusiones: el comportamiento de las empresas generadoras analizadas se puede caracterizar mejor mediante un modelo dinámico, dichas empresas se encuentran comprometidas bajo un grado de colusión inferior al grado de colusión implícita perfecta, y el comportamiento colusivo se mantiene estable en el tiempo gracias a que las empresas realizan ajustes en su producción para disminuir el precio de equilibrio del mercado a niveles menores al precio que correspondería a una colusión perfecta.
