论文摘要
当个人可以具有表达性偏好时，我们研究了一些集体选择问题，即决策者不仅可以关心选择行动的物质利益，还可以关心行动的某些内在道德，或者行动是否符合决策者的某些身份标志者。我们构建了一个简单的框架，用于分析具有这种偏好的机制设计问题，并提出一些结果，重点是我们称为“英国脱欧异常”的现象。主要发现是，尽管确定性机制非常容易受到英国脱欧的敏感，即使有严格的域限制，随机机制也可以确保更积极的结果。
We study some problems of collective choice when individuals can have expressive preferences, that is, where a decision-maker may care not only about the material benefit from choosing an action but also about some intrinsic morality of the action or whether the action conforms to some identity-marker of the decision-maker. We construct a simple framework for analyzing mechanism design problems with such preferences and present some results focussing on the phenomenon we call "Brexit anomaly". The main findings are that while deterministic mechanisms are quite susceptible to Brexit anomaly, even with stringent domain restriction, random mechanisms assure more positive results.
