关于Sen个人主权不可能性定理的注记

A note of Sen libertarian impossibility theorem

研究了社会选择中的个人主权问题 .在定义个人主权的形式化描述的基础上 ,探讨了个人主权与社会选择规则合理指标体系的相容性 .通过分析个人主权与无关方案独立性条件、Pareto准则和正响应条件的关系 ,得到基于Arrow不可能性定理、寡头独裁不可能性定理和否决者存在性定理的个人主权不可能性定理的变式 .

The individual liberal right in social choice is studied. On the basis of the form of the individual liberal right, the compatibility of the individual liberal right and the other properties of the social choice rule are investigated. Through an analysis of the relationship between the liberal right and the conditions for the independence of irrelevant alternatives, and that between the Pareto criterion and the conditions for positive response, the variant of the libertarian impossibility theorem based on the Arrow Impossibility Theorem, the Oligarchic Impossibility Theorem and Vetoer Impossibility Theorem is given.
