Interim pre-play communication
研究了四名或以上玩家在不完全信息博弈中的临时沟通，证明无中介的临时沟通能实现所有沟通均衡，效果等同于有中介沟通。
We study communication in games with incomplete information, four or more players and rational parameters. We show that every communication equilibrium can be implemented with unmediated communication taking place at the interim stage, i.e., after the players learn their types. • Communication allows agents to exchange information and coordinate their choices. • The presence of a trustworthy mediator favors communication. • Unmediated interim communication is as effective as mediated communication.
