Obesity, Weight Loss, and Employment Prospects: Evidence from a Randomized Trial
利用随机分配的减重干预，发现减重能改善肥胖女性的就业前景，但对肥胖男性无显著影响，且减重仅对女性的劳动生产率代理变量有正向作用。
This study presents credible estimates for the causal effect of BMI growth on employment among the obese. By exploring random assignment of a weight-loss intervention based on monetary rewards, I provide convincing evidence that weight loss positively affects the employment prospects of obese women but not of obese men. Consistent with this, significant effects of weight loss on proxy variables for labor productivity are found only for obese women.
