RUI: Nonbinary Social Choice for Economic Environments

这项研究是为了解决众所周知的社会选择问题，在比通常考虑的更现实的环境中。特别是，研究人员将改变社会选择工作中普遍假设的普遍领域、二元性和及物性要求。对于在肯尼斯·阿罗1951年建立的总体框架内工作的研究人员来说，这些要求是最基本的。本研究将采用由现实世界计算的紧急情况形成的选择公理，并开发生成最佳结果集合成员的算法，以允许在选择计算过程中有更大的自由度。这是因为社会可能希望牺牲一些计算效率来打开通往社会选择规则的大门，这种规则比更有效的算法所允许的具有更理想的道德属性。目的是检验定义一种有效的、非二元的、社会选择对应的可能性，这种对应可以用来解决经济学家通常面临的分配福利问题。这项重要的研究代表了基本模型向更现实主义的方向发展，并使社会选择理论和标准经济模型之间有了更好的契合。

This research is to address the well known problems of social choice in environments more realistic than those normally considered. In particular, the researcher will alter the requirements of universal domain, binary-ness, and transitivity commonly assumed in work on social choice. These requirements are among the most basic for researchers working within the general framework established by Kenneth Arrow in 1951. This study will adopt choice axioms shaped by the exigencies for real world computation and develop algorithms generating a member of the set of best outcomes to allow for more latitude in the choice of a computational procedure. This is because society may wish to sacrifice some computational efficiency to open the door to a social choice rule that has more desirable ethical properties than a more efficient algorithm would permit. The goal is to examine the possibility of defining an efficient, nonbinary, social choice correspondence that can be used to settle the kinds of distributional welfare questions that typically confronted economists. This important study represents a move toward greater realism in the basic models, and permits a much better fit between social choice theory and standard economic models.
