摘要
本文证明了在单峰偏好域上Maskin单调性与防策略条件是等价的,并进一步证明了Maskin单调性与联盟防策略是等价的.从而推广了Muller-Satterthwaite(1977)在无限制强序域上得到的结论.在此基础上,利用Mollin(1980)在单峰偏好域上提出的防策略社会选择函数特征化定理,证明了在单峰偏好域上能够突破Muller-Satterthwaite不可能性定理所预示的消极结论.
In this paper, we show firstly the equivalence of Maskin monotonicity and strategy-proofness on the single peaked-ness preference domain, and furthermore that of Maskin monotonicity and coalitional strategy-proofness.Then,Muller-Satter-thwaite(1977) conclusion obtained on unrestricted strong preference domain be extended to the single peakedness preference domain. On the base of this, the negative conclusion implied by Muller-Satterthwaite impossibility theorem be broken by using the characteristic theorem of strategy-proofness social choice function showed by Mollin(1980) on the single peakedness pref-erence domain.
