Abstract

Abstract

En 中文
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.
