异质社会中的匿名投票
Anonymous voting in a heterogeneous society
AI总结:
本文研究二元社会选择中的匿名投票机制设计,发现两智能体下序数多数规则最大化预期福利,而三智能体及以上时基数机制可优于序数机制。
摘要:
我们研究二元社会选择环境中的投票机制设计,其中智能体的基数估值是独立的,但不一定同分布。该机制必须是匿名的——结果对报告值的排列保持不变。我们证明,如果存在两个智能体,预期福利总是由序数多数规则最大化;但如果存在三个或更多智能体,在某些环境中,考虑偏好强度的基数机制会优于任何序数机制。
英文摘要:
We study the design of voting mechanisms in a binary social choice environment where agents' cardinal valuations are independent but not necessarily identically distributed. The mechanism must be anonymous -- the outcome is invariant to permutations of the reported values. We show that if there are two agents then expected welfare is always maximized by an ordinal majority rule, but with three or more agents there are environments in which cardinal mechanisms that take into account preference intensities outperform any ordinal mechanism.
