论文摘要
如果偏好域允许设计一致的社会选择功能(此后,规则),则称为非界限域,这些域名是非执行和防止策略的。我们研究了一类称为一维域的偏好域,并确定唯一的秒性属性(由Aswal,Chatterji和Sen(2003)引入)表征了所有非划界域。主要的贡献是基于称为“不变性的两投规则”的简单属性,对这些域上所有非划分,一维域和防护策略规则的详尽分类。构成分类的偏好域是半单调的峰域(由Chatterji,Sanver和Sen(2013))和半杂交域(此处介绍)(此处介绍),它们是单峰域的两个适当弱化,并被证明允许策略策略规则依赖选民偏好的非言论信息;这些领域的规范规则分别是投影规则和混合规则。作为分类的完善,单峰域和混合域是唯一一项一维域,该领域强迫策略规则由选民的偏好峰完全决定。
A preference domain is called a non-dictatorial domain if it allows the design of unanimous social choice functions (henceforth, rules) that are non-dictatorial and strategy-proof. We study a class of preference domains called unidimensional domains and establish that the unique seconds property (introduced by Aswal, Chatterji, and Sen (2003)) characterizes all non-dictatorial domains. The principal contribution is the subsequent exhaustive classification of all non-dictatorial, unidimensional domains and canonical strategy-proof rules on these domains, based on a simple property of two-voter rules called invariance. The preference domains that constitute the classification are semi-single-peaked domains (introduced by Chatterji, Sanver, and Sen (2013)) and semi-hybrid domains (introduced here) which are two appropriate weakenings of single-peaked domains and are shown to allow strategy-proof rules to depend on non-peak information of voters' preferences; the canonical rules for these domains are the projection rule and the hybrid rule respectively. As a refinement of the classification, single-peaked domains and hybrid domains emerge as the only unidimensional domains that force strategy-proof rules to be determined completely by voters' preference peaks.
