Implementability of correlated and communication equilibrium outcomes in incomplete information games (Q2453491)

The author considers a special class of games with incomplete information determined as Bayesian games, where players can receive signals about the ``state of nature'', which divide players into different types, and messages. Having signals and messages, players choose their actions. Mechanisms of this information processes are differentiated by the messages' properties, for instance, by their content, by their mutual dependence (correlation), by their randomness, etc. Each of these kinds yields a different game equilibrium concept. The author gives some relations among these concepts and a basis for their classification.
