General revealed preference theory
将经济学中的标准显示偏好分析推广，证明了一个充分条件，使得经济理论的显示偏好表述具有普适含义且可递归枚举，并应用于群体偏好和纳什均衡理论。
We generalize the standard revealed preference exercise in economics, and prove a sufficient condition under which the revealed preference formulation of an economic theory has universal implications and when these implications can be recursively enumerated. We apply our theorem to two theories of group behavior: the theory of group preference and the theory of Nash equilibrium.
