Does Inequality Harm the Middle Class?
利用瑞士家庭面板数据，研究发现经济不平等（以基尼系数和豪车注册数衡量）与中产阶级的收入满意度之间存在稳健的负相关关系。
The paper provides estimates of the effect of economic inequality on middle class well being in Switzerland. Economic well being is proxied by a person's satisfaction with his/her income. Two inequality indicators are used, one standard (the Gini coefficient of the pre-tax income distribution) and one novel (the number of luxury car registrations per 1000 population). Identification is through cross-sectional variation of these indicators at various levels of spatial aggregation. Results using data from the Swiss Household Panel confirm the existence of a robust inverse relationship between inequality and satisfaction among the middle class.
