The Use of Information in Repeated Games with Imperfect Monitoring
形式化了改进监督有助于长期关系协调的观点，证明当信号质量按布莱克威尔意义改善时，不完全监督重复博弈的纯策略序贯均衡支付集在集合包含意义上扩大，并识别了扩大的方向。
The present paper formalizes the idea that improved monitoring helps coordination in long term relationships. Specifically, the pure-strategy sequential equilibrium payoff set is shown to expand (in the sense of set inclusion) in repeated games with inperfect monitoring, when the quality of the signal improves in Blackwell's sense. Furthermore, the directions of the expansion are identified.
