Long Cheap Talk
证明，在信息不对称的两人博弈中，允许廉价交谈时，长对话比单次消息能实现更多均衡结果，并刻画了所有均衡收益。
With cheap talk, more can be achieved by long conversations than by a single message—even when one side is strictly better informed than the other. ("Cheap talk" means plain conversation—unmediated, nonbinding, and payoff-irrelevant.) This work characterizes the equilibrium payoffs for all two-person games in which one side is better informed than the other and cheap talk is permitted.
