基于真实基数投票方案的相对社会福利最大化

Maximization of Relative Social Welfare on Truthful Cardinal Voting Schemes

Sinya Lee

摘要:

研究了具有基数偏好的真实单一获胜者投票方案与经典范围投票方案的相对社会福利最大化问题。区间投票机制是一种简单直接的机制,它确定性地最大化社会福利。然而,该方案被认为是不真实的,我们研究了真实的机制,最大限度地提高其预期的社会福利的比例,由范围投票方案实现的社会福利。本文提出了一种实现$Ω(m^{-2/3})$比率的方案。证明了这个界是渐近紧的,并且不可能找到更好的投票方案。

英文摘要:

Consider the the problem of maximizing the relative social welfare of truthful single-winner voting schemes with cardinal preferences compared to the classical range voting scheme. The range voting scheme is a simple and straightforward mechanism which deterministically maximizes the social welfare. However, the scheme that is known to be non-truthful and we studied the truthful mechanism that maximize the ratio of its expected social welfare to the social welfare achieved by the range voting scheme. We provide a scheme which achieve a ratio of $Ω(m^{-2/3})$ in this paper. It is proved that this bound is tight asymptotically and it is impossible to find a better voting scheme.
