Rationalization of indecisive choice behavior by pluralist ballots
提出一种有限理性方法解释犹豫不决的选择行为，其中菜单中的项目可能全部、部分或都不被选中。通过选民群体编码的二元关系定义s-多元主义，证明所有多元主义形式等价于公理α，并考察了最小份额和过半份额的特殊形式。
We describe a bounded rationality approach for indecisive choice behavior, in which all, some or none of the items in a menu may be selected. Choice behavior is s-pluralist if there is a population of voters —encoded by arbitrary binary relations— such an item is selected from a menu if and only if it is endorsed by a share of voters larger than s. We prove that all forms of pluralism are equivalent to Axiom α. We also examine special forms of pluralism, in which the share of voters is either minimum or more than one half.
