Measuring Future Grandparents' Preferences for Equality and Relative Standing
通过实验选择测量个人对风险、不平等和相对地位的偏好，发现人们既厌恶不平等又关注相对收入，并基于此分析社会福利函数中边际效用可能为负的情况。
Individuals ’ aversion to risk and inequality, and their concern for relative standing, are measured through experimental choices between hypothetical societies. It is found that, on average, individuals are both fairly inequality-averse and have a strong concern for relative income. The results are used to illustrate welfare consequences based on a utilitarian SWF and a modified CRRA utility function. It is shown that the social marginal utility of income may then become negative, even at income levels that are far from extreme. 1.
