A Measure of Behavioral Heterogeneity
提出一种基于选择的度量方法，评估随机个体在随机菜单上选择不同的概率，并给出公理基础和分解为个体内与个体间异质性的结果。
In this paper, we propose a novel way to measure behavioral heterogeneity in a population of stochastic individuals. Our measure is choice-based; it evaluates the probability that, over a randomly selected menu, the sampled choices of two sampled individuals differ. We provide axiomatic foundations for this measure and a decomposition result that separates heterogeneity into its intrapersonal and interpersonal components.
