The Folk Theorem in Repeated Games With Anonymous Random Matching
证明了在匿名随机匹配的折现重复博弈中，只要阶段博弈满足完全维度条件，即使没有记录、沟通或公开随机化，民间定理依然成立，适用于非均匀匹配和非对称收益。
We prove the folk theorem for discounted repeated games with anonymous random matching. We allow non‐uniform matching, include asymmetric payoffs, and place no restrictions on the stage game other than full dimensionality. No record‐keeping or communication devices—including cheap talk communication and public randomization—are necessary.
