This paper analyzes the case of Spain in the period from 1993 to 2005, when intense reforms in several industries took place in the country. We observe an increase in collusion and trust practices in liberalized industries, what requires an increase in the resources dedicated to antitrust policy. An econometric estimation demon- strates the influence that certain regulatory dimensions have on antitrust activity. Deregulation has an additional positive effect on antitrust activity. We also observe a learning effect in industries due to previous sanctions. Finally, we find a complementarity effect of regulatory agencies on the antitrust policy.// El artículo analiza la relación entre los cambios de regulación en los sectores y la aparición de casos de prácticas prohibidas por la legislación en materia de defensa de la competencia. Se estudia el caso de España en el periodo comprendido de 1993 a 2005, durante el que se promulgaron intensas reformas desreguladoras en diversos sectores y al mismo tiempo existió una cierta estabilidad en el marco de la defensa de competencia. El análisis permite demostrar, a partir de un modelo econométrico, la influencia que las medidas desreguladoras tienen en el incremento de prácticas contrarias a la ley. También se comprueba que al mismo tiempo y gracias a la labor de los órganos de defensa de la competencia, se produce un efecto de aprendizaje en aquellos sectores en los que se instruyen expedientes sancionadores. Finalmente, se observa que los organismos reguladores sectoriales son complementarios al órgano de defensa de la competencia.
