Long Cheap Talk

  • Robert J. Aumann
  • Sergiu Hart

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. Copyright The Econometric Society 2003.
