我们研究了一个无限重复的囚徒困境与不完善的监督,并考虑的可能性,球员的不同活动的相互联系,加强隐式共谋。我们证明了一个慷慨的达特的纳什均衡存在的充分必要条件。这种均衡,如果存在的话,是独一无二的。当监控接近完美时,这种均衡达到了近似的效率,其中贴现因子是固定的。
We investigate an infinitely-repeated prisoners' dilemma with imperfect monitoring and consider the possibility that the interlinkage of the players' distinct activities enhances implicit collusion. We show a necessary and sufficient condition for the existence of a generous tit-for-tat Nash equilibrium. Such an equilibrium, if it exists, is unique. This equilibrium achieves approximate efficiency when monitoring is almost perfect, where the discount factors are fixed.
