摘要
We conducted experiments on Lipnowski et al. (2020)’s model of cheap talk with transparent motives using a broker-investor game with belief elicitation. We find that senders largely adopted the equilibrium strategy of a median cutoff policy, and variations in brokerage proportions do not affect the information conveyed. However, we find evidence of inconsistent belief updating; some receivers did not update. Most receivers failed to trade off more accurate beliefs against higher brokerage fees. Subjects showed limited learning, primarily identifying whether others were lying or trusting, rather than learning the partner's strategy. Some pairs exhibited grim-trigger-strategy behaviors to sustain cooperation through sender truth-telling and receiver trusting. Other pairs showed distrust from the onset through sender babbling or lying and receiver not-acting or counteracting.
