报告摘要：

This study presents a non-parametric revealed preference analysis of heterogeneity in risk preference. We first propose a uniqueness index to measure the degree that an individual shares the same utility function with others from the population, and then apply the index to analyze group heterogeneity. Our analysis uses the experimental data by Choi et al. (2014), in which subjects make portfolio choices subject to different budget constraints. We observe that females exhibit a lower degree of both individual uniqueness and group heterogeneity, compared to the male counterpart. In addition, heterogeneity between males and females is intermediate to that within the two genders, and heterogeneity between couples is smaller than that of non-couples. We observe a weaker heterogeneity based on wealth.
