Obvious Ex Post Equilibrium
提出一种新的解概念“明显的后验均衡”，用于衡量机制在相互依赖价值环境中的认知简单性，并证明升价拍卖在标准假设下存在有效的该均衡。
I propose a new solution concept, obvious ex post (OXP) equilibrium. This is a formal standard of cognitive simplicity for mechanisms, in settings with interdependent values. Under some standard assumptions, the ascending auction has an efficient OXP equilibrium. I discuss a decision theoretic foundation for OXP mechanisms.
