Relative Status and Well-Being: Evidence from U.S. Suicide Deaths
利用美国自杀死亡数据，研究发现控制自身收入后，他人收入越高，个人自杀风险越大，表明人际收入比较对幸福感有重要影响。
Abstract We assess the importance of interpersonal income comparisons using data on suicide deaths. We examine whether suicide risk is related to others' income, holding own income and other individual and environmental factors fixed. We estimate models of the suicide hazard using two independent data sets: the National Longitudinal Mortality Study and the National Center for Health Statistics' Multiple Cause of Death Files combined with the 5% Public Use Micro Sample of the 1990 decennial census. Results from both data sources show that, controlling for own income and individual characteristics, individual suicide risk rises with others' income.
