本文考虑Shapley和Scarf(J Math Econ 1:23-37,1974)提出的对象分配问题。我们研究安全实现(西条等人。in Theor Econ 2:203-229,2007),即在优势策略和纳什均衡中的双重实现。我们证明了(1)一个独立的理性解是安全可实现的当且仅当它是无交易解,(2)一个中立解是安全可实现的当且仅当它是一个序列独裁,(3)一个有效解是安全可实现的当且仅当它是一个序列独裁.此外,我们提供了一个完整的表征安全可实现的解决方案在两个代理的情况下:解决方案是安全可实现的,当且仅当它是一个常数的解决方案或串行独裁。
This paper considers the object allocation problem introduced by Shapley and Scarf (J Math Econ 1:23–37, 1974). We study secure implementation (Saijo et al. in Theor Econ 2:203–229, 2007), that is, double implementation in dominant strategy and Nash equilibria. We prove that (1) anindividually rationalsolution is securely implementable if and only if it is the no-trade solution, (2) aneutralsolution is securely implementable if and only if it is a serial dictatorship, and (3) anefficientsolution is securely implementable if and only if it is a sequential dictatorship. Furthermore, we provide a complete characterization of securely implementable solutions in the two-agent case: a solution is securely implementable if and only if it is either a constant solution or a serial dictatorship.
