中文摘要
本文通过生成与信念无关、可解释为边际替代率（MRS）的统计量，对收入平等与流动性偏好进行量化。在其他条件相同的情况下，美国居民愿意将平均收入减少2,744美元，以使90/10收入不平等比率降低一个单位；愿意将平均收入减少1,228美元，以使收入从最低五分位向上流动的比例提高一个百分点。民主党人与无党派人士对这两个社会变量的偏好相近，而共和党人在收入不平等和收入流动性方面的边际替代率约为民主党人与无党派人士的三分之二。
Abstract
Abstract This paper quantifies preferences for income equality and mobility by generating statistics that are uncorrelated with beliefs and can be interpreted as marginal rates of substitution (MRS). All things being equal, U.S. residents are willing to reduce average income by $2,744 to reduce the 90/10 income inequality ratio one unit, and $1,228 to increase income mobility from the bottom quintile one percentage point. Democrats and Independents have similar preferences for both social variables, while Republicans have an MRS that is about two-thirds that of Democrats and Independents for both income inequality and mobility.
