Greenberg et al. (Econ Theory 40:91–112, 2009. https://doi.org/10.1007/s00199-008-0349-5) offered a solution concept of a “mutually acceptable course of action” (MACA) for situations in which rational individuals with different beliefs and views of the world agree to a shared course of action. In this paper we investigate epistemic conditions for MACA, in terms of information, beliefs, and rationality. Within a semantic framework, we formulate and show, using the notion of “lexicographic probability system” (LPS) introduced by Blume et al. (Econometrica 59:61–79, 1991a), that MACA is the logical consequence of “perfect” rationality, common belief in “perfect” rationality, and correct mutual belief in agreement on the shared course of action. We also demonstrate how epistemic characterizations for “perfect” versions of solution concepts can be derived from our epistemic characterization for MACA, by varying the degree of completeness of the shared course of action.

格林伯格等。（经济理论40：91–112，2009年。https://doi.org/10.1007/s00199-008-0349-5）提出了一种解决方案概念，即在理性的情况下，“相互接受的行动方针”（MACA）对世界有不同信仰和看法的个人都同意采取共同的行动方针。在本文中，我们从信息，信念和合理性方面研究了MACA的认知状况。在语义框架内，我们使用Blume等人引入的“词典概率系统”（LPS）概念来表述和展示。（Econometrica 59：61–79，1991a），MACA是“完美”理性，对“完美”理性的共同信念以及对共同行动方针达成共识的正确信念的逻辑结果。
