Does job loss cause ill health?
利用健康与退休研究的纵向数据，通过企业倒闭导致的外生性失业，估计失业对接近退休年龄员工健康的影响，发现失业对身心健康无显著因果效应，暗示失业与健康不佳的关联可能源于反向因果。
This study estimates the effect of job loss on health for near elderly employees based on longitudinal data from the Health and Retirement Study. Previous studies find a strong negative correlation between unemployment and health. To control for possible reverse causality, this study focuses on people who were laid off for an exogenous reason - the closure of their previous employers' business. I find no causal effect of exogenous job loss on various measures of physical and mental health. This suggests that the inferior health of the unemployed compared to the employed could be explained by reverse causality.
