September 2018The Effects of Medicaid Expansion on Labor Market Outcomes: Evidence from Border Counties
with Xiaohui (Ronnie) Guo, Chad D. Meyerhoefer: w25105
This paper provides new empirical evidence on the employment and earning effects of the recent Medicaid expansion. Unlike most existing studies that use a conventional state and year fixed effects approach, our main identification strategy is based on the comparison of employment and wages in contiguous county-pairs in neighboring states (i.e. border counties) with different Medicaid expansion status. Using the 2008-2016 Quarterly Census of Employment and Wages, we estimate a set of distributed lag models in order to examine the dynamic effects of Medicaid expansion. Results from our preferred specification suggest a small but statistically significant decrease in employment of 1.3 percent one year after the Medicaid expansion. This disemployment effect is transitory and appears to primari...

September 2013The Effect of Depression on Labor Market Outcomes
with Chad D. Meyerhoefer, Samuel H. Zuvekas: w19451
We estimated the effect of depression on labor market outcomes using data from the 2004-2009 Medical Expenditure Panel Survey. After accounting for the endogeneity of depression through a correlated random effects panel data specification, we found that depression reduces the likelihood of employment. We did not, however, find evidence of a causal relationship between depression and hourly wages or weekly hours worked. Our estimates are substantially smaller than those from previous studies, and imply that depression reduces the probability of employment by 2.6 percentage points. In addition, we examined the effect of depression on work impairment and found that depression increases annual work loss days by about 1.4 days (33 percent), which implies that the annual aggregate productivity ...
