标题： Revealed Stochastic Preference: A One-Paragraph Proof and Generalization

摘要： 麦法登和里彻（1991）以及后来的麦法登（2005）表明，揭示性随机偏好公理通过有限全集选择空间上的随机效用模型表征了选择概率的可理性化。本简要证明该结果，并将其扩展到集值选择。后者需要与麦法登（2005）中报告的不同公理。 显示英文摘要

摘要： McFadden and Richter (1991) and later McFadden (2005) show that the Axiom of Revealed Stochastic Preference characterizes rationalizability of choice probabilities through random utility models on finite universal choice spaces. This note proves the result in one short, elementary paragraph and extends it to set valued choice. The latter requires a different axiom than is reported in McFadden (2005).
