Limited Foresight May Force Cooperation
研究有限理性玩家在重复博弈中的行为,提出有限预测均衡概念,并证明在重复囚徒困境中,有限远见有时能导致纯合作路径,而纯非合作路径则不会出现。
This paper considers discounted repeated games with boundedly rational players. In each period, player i chooses his current action on the basis of his forecast about the forthcoming ni action profiles; his assessment of the payoffs he will obtain next depends on his state of mind, which is non-deterministic. A limited forecast equilibrium is such that after every history the limited horizon forecasts formed by the players are correct. The set of all limited forecast equilibria is characterized and constructed. Application to the repeated prisoner's dilemma shows that limited foresight may sometimes induce purely cooperative paths while purely non-cooperative paths cannot arise.
