Does health insurance make people happier? Evidence from Massachusetts’ healthcare reform

We study the effects of Massachusetts' healthcare reform on individuals' subjective well-being. Using data from the Behavioral Risk Factor Surveillance System, we find that the reform significantly improved Massachusetts residents' overall life-satisfaction. This result is robust to various sensitivity checks and a falsification test. We also find that the reform improved mental health. An additional analysis on the Tennessee healthcare reform supports our findings' external validity. Using the reform as an instrument for health insurance coverage, we estimate its large impact on overall life-satisfaction. Our results provide novel evidence on the psychological consequences of Massachusetts' healthcare reform

The Great Recession and Workers' Health Benefits

During a recession, cost-sharing of employer-sponsored health benefits could increase to reduce labor costs in the U.S. Using a variation in the severity of recession shocks across industries, I find evidence that the enrollment rate of high deductible health plans (HDHPs) among workers covered by employer-sponsored health benefits increased more among firms in industries that experienced severe recession shocks. As potential mechanisms, I study employer-side and worker-side mechanisms. I find that employers changed health benefit offerings to force or incentivize workers to enroll in HDHPs. But I find little evidence of an increase in workers??? demand for HDHPs due to a reduction in income. These results suggest that the HDHP enrollment rate increased during the Great Recession, as employers tried to save costs of offering health benefits

Maternal breastfeeding and children's cognitive development

Do children with lower test scores benefit more from breastfeeding than those with higher scores? In this paper, I examine the distributional effects of maternal breastfeeding on the cognitive test scores of 11,544 children who were born in 2000 and 2001 in the United Kingdom using a semiparametric quantile regression model. I find evidence that maternal breastfeeding has larger positive impacts on children with lower test scores. Effects for children below the 20th percentile are about 2-2.5 times greater than those for children above the 80th percentile. I also find that these distributional effects are larger when the duration of breastfeeding is extended. One policy implication is that a public policy aims at promoting breastfeeding might narrow a disparity in children's cognition
