Stochastic Choice and Preferences for Randomization
通过实验让受试者多次重复回答相同问题，发现大多数人在重复间隔远或连续重复时都表现出随机选择行为，这对随机选择模型有启示。
We conduct an experiment in which subjects face the same questions repeated multiple times, with repetitions of two types: (1) following the literature, the repetitions are distant from each other; (2) in a novel treatment, the repetitions are in a row, and subjects are told that the questions will be repeated. We find that a large majority of subjects exhibit stochastic choice in both cases. We discuss the implications for models of stochastic choice.
