In this paper I formulate and estimate an empirical dynamic oligopoly model that incorporates consumer learning, consumer heterogeneity and forward-looking rms. I apply this model to explain the evolution of pharmaceutical markets after patent expiration, and to address its related policy issues. I develop a practical method to estimate the parameters of(More)
