Aumann and Hart (Econometrica, Nov. 2003) have shown that in games of one-sided incomplete information, the set of equilibrium outcomes achievable can be expanded considerably if the players are allowed to communicate without exogenous time limits and completely characterise the equilibria from...

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...
