A Necessary and Sufficient Condition for Two-Person Nash Implementation
刻画了两人社会选择对应可被纳什实现的充要条件，并据此给出域限制，从而构造出非独裁且帕累托有效的可纳什实现的社会选择对应。
The main result of this paper is to characterize the class of two-person social choice correspondences which are Nash-implementable. The characterization result is used to formulate domain restrictions which allow the construction of non-dictatorial and Pareto-efficient social choice correspondences which are Nash-implementable.
