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.
