Information and Timing in Repeated Partnerships
区分了降低利率、缩短行动固定周期和缩短信息报告滞后对重复合作博弈的影响，发现不完全监督下后两者在小利率时反而削弱合作。
In a repeated partnership game with imperfect monitoring, we distinguish among the effects of (1) reducing the interest rate, (2) shortening the period over which actions are held fixed, and (3) shortening the lag with which accumulated information is reported.All three changes are equivalent in games with perfect monitoring.With imperfect monitoring, reducing the interest rate always increases the possibilities for cooperation, but the other two changes always have the reverse effect when the interest rate is small.
