内容提要:

Indirect reciprocity based on certain reputation systems is an important way to promote cooperation when repeated interaction becomes rare under globalization. Theoretically, coherent notions of reputation scores require knowledge of higher-order histories. Yet, how people use the acquired higher-order information to aid cooperation decisions is an open empirical question. We study a random-matching Prisoners’ Dilemma experiment with optional history information up to the second order, i.e. including the partner’s own previous partners’ action history. With the help of our newly defined continuous extension of some well-known reputation scores, we are the first to find that some simplified versions of standing and judging significantly affect the cooperation decision. More than half of subjects prove to be responsive to the higher-order scores, which also comes along with a certain payoff advantage. The positive reputation effect is much stronger when people have first played the baseline PD games without history information, where vanishing cooperation is inevitable. Under such a condition, subjects are also inclined to be more cooperative when both parties display high reputation scores.
