I consider changes in labor markets across U.S. states and counties around the enactment of the Affordable Care Act in 2010 and its implementation in 2014. I find that counties with large fractions of uninsured (and therefore a large exposure to the ACA) before the enactment or the...

A vast literature studies the behavioural impacts of health care reforms, often coming to controversial conclusions. Here we examine the time allocation effects of the Affordable Care Act, also known as Obama Care, focusing on two ACA pillars: Medicaid expansion, which increased access to public...

This study leverages geographic variation in health insurance premiums to estimate the impact of the Affordable Care Act on the US labor market. We link data from the Current Population Survey from 2010 to 2015 with geographic-specific premiums from the health insurance marketplaces. Our...

We investigate whether taxpayers respond to a large, ACA-induced upward tax notch at the Federal Poverty Level. Using administrative tax data, we document bunching in the income distribution and provide estimates of the taxable income elasticity. Our estimates are the only ones using US data...

We estimate the effect of the Affordable Care Act Medicaid expansion on county-level mortality in the first four years following expansion. We find a reduction in all-cause mortality in ages 20 to 64 equaling 11.36 deaths per 100,000 individuals, a 3.6 percent decrease. This estimate is largely...

We study age-rating restrictions in the health insurance marketplaces introduced by the Affordable Care Act. Because most buyers are subsidized, although age-rating restrictions affect pre-subsidy premiums, participation is primarily driven by subsidy generosity rather than pricing decisions....

We examine the early effects of U.S. state Medicaid expansions under the Affordable Care Act (ACA) on substance use disorder (SUD) treatment utilization. We couple administrative data on admissions to specialty SUD treatment and prescriptions for medications used to treat SUDs in outpatient...

The goal of the Affordable Care Act (ACA) was to achieve nearly universal health insurance coverage through a combination of mandates, subsidies, marketplaces, and Medicaid expansions, most of which took effect in 2014. We use data from the Behavioral Risk Factor Surveillance System to examine...

This study contributes to the literature on supply-side adjustments to insurance expansions by examining the effect of the Affordable Care Act (ACA) on ambulance response times. Exploiting temporal and geographic variation in the implementation of the ACA as well as pre-treatment differences in...
