The effect of continuous-time cheap talk in the experimental minimum effort game

Abstract

ABSTRACT We experimentally investigated whether continuous-time cheap talk improves the effort level in a minimal effort game with multiple Pareto-ranked Nash equilibria. In each round of the game, a player freely changes the message before he or she makes decisions, and constantly monitors other members’ messages. We have two results. First, continuous-time cheap talk realizes a higher effort level than does one-shot cheap talk. Second, the group in which every member chooses the maximum effort in the first two rounds eventually achieves an efficient outcome.
