演講摘要 : We study how discounting and monitoring jointly determine whether cooperation is possible in repeated games with imperfect (public or private) monitoring. Our main result provides a simple bound on the strength of players' incentives as a function of discounting, monitoring precision, and on-path payoff variance. We show that the bound is tight in the low-discounting/low-monitoring double limit, by establishing a folk theorem where the discount factor and the monitoring structure can vary simultaneously.
