报告摘要:

We conduct an experiment on an infinitely repeated favor exchange game under complete and incomplete information. Since the efficient strategy is not incentive compatible under incomplete information, we focus on a sub-class of Markov strategies named Bounded Favors Bank (BFB), where the state variable is the net number of favors and its dimension is bounded. We consider two types of strategies in this class: BFBr which rewards the player who made the maximum net number of favors and BFBp which punishes the player who received the maximum net number of favors. When moving from complete information to incomplete information, we find that subjects cooperate to exchange favors substantially less often and the most commonly employed strategy switches from the efficient one to the non-cooperative one. Under incomplete information, BFB is played with a statistically significant probability, but providing summary information on the net number of favors does not increase the frequency of playing such class of strategies. Furthermore, BFBr is played more often than BFBp, indicating that using a form of reward may have more compliance than using a form of punishment in a long-term bilateral relationship with private information.
