  • Resumen
    • This paper presents an alternative or enhanced approach to information acquisition in Cournot markets with stochastic demand in which the cost of information acquisition is endogenously determined by firms� information p urchasing strategy. I propose a two-stage model in which in the first stage each firm decides whether it will join a coalition to purchase information and therefore share the cost of information acquisition, to individually purchase information, or to remain uninformed. In the second-stage firms engage in Cournot competition to choose output. The model I propose encompasses the main assumptions of the current view on information acquisition, mainly those related to the role of i nformation and how it affects firms� profits. However, I will argue that by adding natural assumptions on oligopolists� behavior, I can offer a model that provides a better description of firms� actions and trade-offs than the standard view. The paper also offers experimental evidences supporting the new approach to information acquisition.
