Implementation of communication equilibria by correlated cheap talk: The two-player case
研究了两人有限贝叶斯博弈中,任何沟通均衡都能通过扩展博弈中的策略型相关均衡实现,该扩展博弈允许玩家在行动前进行可能无限长但均衡中几乎必然有限的直接廉价交谈。
We show that essentially every communication equilibrium of any finite Bayesian game with two players can be implemented as a strate-gic form correlated equilibrium of an extended game, in which before choosing actions as in the Bayesian game, the players engage in a pos-sibly infinitely long (but in equilibrium almost surely finite), direct, cheap talk.
