    Se estudia la evolución de la competencia en el mercado español de electricidad, proponiendo un análisis mediante teoría de juegos. Se elabora un modelo basado en juegos dinámicos siguiendo el concepto de Equilibrio Perfecto de Markov, tomando como bloque elemental una descripción de la competencia en el mercado de producción según un enfoque tipo Cournot. Se considera la entrada de nuevos competidores. La naturaleza estocástica de los principales factores exógenos se incorpora mediante árboles binomiales. El modelo se implementa numéricamente y los resultados obtenidos incluyen la competencia y el ejercicio de poder de mercado, las pautas evolutivas de la actividad inversora, el papel de las barreras a la entrada, la eficiencia del sector en relación al comportamiento perfectamente competitivo, así como el excedente total y su distribución entre industria y consumidores Evolution of competition in Spanish power market is studied through a game theoretic approach. A dynamic game model for the long term competitive dynamics is developed based on Markov Perfect Equilibrium concept using a Cournot type description of the short run competition as building block. Entry of new competitors is considered. Stochastic behavior of main exogenous factors is described by means of binomial trees. The model is numerically implemented and among the results it can be highlighted the level of competition and the degree of market power, dynamic investment patterns, the role of entry barriers, the efficiency of the sector as compared to a perfectly competitive market and total market surplus as well as its distribution between industry and consumers.
