讲座题目：The revelation principle with information networks
讲座摘要：We study the revelation principle on information networks （digraphs） whereby agents have access to information that their neighbors have. We show, through an example, that the revelation principle may fail in the presence of networks. We provide a full characterization of the revelation principle in a framework of Bayesian games with communication under an information network structure—-that is, any equilibrium of any Bayesian communication game with information network G can be represented by an incentive-compatible direct-revelation mechanism iff G is a transitive network （that is closed under the directed-link transitivity）. This gives rise to a well-defined notion of G-communication equilibria, which is composed of a convex polyhedron of incentive-compatible direct-revelation mechanisms under the information network structure. Our approach is applicable to a plethora of revelation principles discussed in the literature.
