Communication in Games of Incomplete Information: The Two-player Case



We study the effect of communication in two-person games of incomplete information. We show that any rational mediated communication mechanism satisfying a Nash domination condition can be implemented as the perfect Bayesian equilibrium of a communication extension of the original game and ends in finite time with probability 1.
