The Impact of Health on Labor Market Outcomes: Evidence from a Large-Scale Health Experiment
利用一项大规模随机对照试验（MRFIT）的数据，研究发现健康干预措施显著提高了男性参与者的收入和家庭收入，且效果在不同健康水平和职业群体间差异不大。
While economists have posited that health investments increase earnings, isolating the causal effect of health is challenging due to reverse causality and unobserved heterogeneity. We examine the labor market effects of a randomized controlled trial, the Multiple Risk Factor Intervention Trial (MRFIT), which monitored nearly 13,000 men for over six years. We find that this intervention, which provided a bundle of treatments to reduce coronary heart disease mortality, increased earnings and family income. We find few differences in estimated gains by baseline health and occupation characteristics.
