An experimental study on the equilibrium selection in the n-person Prisoners Dilemma with information structure

我们考虑以下修改的囚徒困境：自然选择的顺序与50-50的机会，只有第一个运动者的背叛是由第二个观察。当收益结构满足一定条件时，存在一个博弈双方都选择合作的纳什均衡。本研究的目的是检验一个假设，即与通常的囚徒困境相比，在修正的囚徒困境中合作的可能性得到了增强。通过一个实验，当背叛动机在一定范围内时，这一假设在1%的显著性水平上得到了支持。

We consider the following modified Prisoner's Dilemma : Nature chooses the order of moves with 50-50 chance and only the first mover's Defection is observed by the second. When the payoff structure satisfies a certain condition, there exists a Nash equilibrium in which both players choose Cooperation in its play. The purpose of this study is to test the hypothesis that the possibility of cooperation is enhanced in the modified Prisoner's Dilemma in comparison with the usual one. By an experiment, this hypothesis was supported at the 1% significance level when the incentive for Defection is in a certain range.
