Communication, correlation and cheap-talk in games with public information

  • Heller, Yuval
  • Solan, Eilon
  • Tomala, Tristan

This paper studies extensive form games with public information where all players have the same information at each point in time. We prove that when there are at least three players, all communication equilibrium payoffs can be obtained by unmediated cheap-talk procedures. The result encompasses repeated games and stochastic games.
