论文摘要
我们研究了代理具有顺序偏好并允许随机分组的一般集体选择问题的效率。我们探讨了偏好概况的结构，即前ante和事后效率重合一致，对已知结果提供了统一的观点，并提供了一些新的特征。结果对研究的机制有影响，包括随机串行独裁统治和许多特定环境，包括二分法，单峰和社会选择领域。
We study efficiency in general collective choice problems where agents have ordinal preferences and randomization is allowed. We explore the structure of preference profiles where ex-ante and ex-post efficiency coincide, offer a unifying perspective on the known results, and give several new characterizations. The results have implications for well-studied mechanisms including random serial dictatorship and a number of specific environments, including the dichotomous, single-peaked, and social choice domains.
