The Impact of Obesity on Wages
用更大数据集和多种回归方法，发现体重降低白人女性工资约9%，相当于少一年半教育或三年工作经验，而其他族群的负相关可能源于未观测异质性。
Previous studies of the relationship between body weight and wages have found mixed results. This paper uses a larger data set and several regression strategies in an attempt to generate more consistent estimates of the effect of weight on wages. Differences across gender, race, and ethnicity are explored. This paper finds that weight lowers wages for white females; OLS estimates indicate that a difference in weight of two standard deviations (roughly 65 pounds) is associated with a difference in wages of 9 percent. In absolute value, this is equivalent to the wage effect of roughly one and a half years of education or three years of work experience. Negative correlations between weight and wages observed for other gender-ethnic groups appear to be due to unobserved heterogeneity.
