演講摘要 : We explore the restrictions that prior beliefs impose on higher order beliefs. We consider a generalization of belief operator, introduce a notion of potential, and study implications of existence/non-existence of a potential with a certain property. In particular, we obtain a nontrivial lower bound of the prior robability of a common belief event that is uniform over type spaces. As an application, a full characterization of robust equilibrium is obtained for binary supermodular games. Journal of Economic Literature Classication Numbers: C72, D82.
