Résumé
This paper studies identification and estimation of dynamic games when the underlying information structure is unknown to the researcher. To tractably characterize the set of model predictions while maintaining weak assumptions on players' information, we introduce Markov correlated equilibrium, a dynamic analog of Bayes correlated equilibrium. The set of Markov correlated equilibrium predictions coincides with the set of Markov perfect equilibrium predictions that can arise when the players might observe more signals than assumed by the analyst. We characterize the sharp identified sets under varying assumptions on what the players minimally observe. We also propose computational strategies for dealing with the non-convexities that arise in dynamic environments.
