摘要。通过在确定性框架中使用类似于吉巴德（吉巴德a (1973) Econometrica 41:587 - 601）使用的推理线，我们提供了一个更透明和直观的证明，证明以下随机独裁结果在概率框架中，这是吉巴德（吉巴德a (1977) Econometrica 41:665 - 681）的更一般结果的H. sudnenschein的推论：决策方案是帕累托最优事后证明和策略证明，当且仅当它是一个随机独裁。
Abstract. By using a line of reasoning similar to the one used by Gibbard (Gibbard A (1973) Econometrica 41: 587–601) in the deterministic framework, we provide a more transparent and intuitive proof of the following random dictatorship result in the probabilistic framework, which is a corollary credited to H.␣Sonnenschein of the more general result of Gibbard (Gibbard A (1977) Econometrica 45: 665–681): A decision scheme is Pareto optimific ex post and strategy proof if and only if it is a random dictatorship.
