Using premium subsidies for private coverage, an individual mandate, and Medicaid expansion, the Affordable Care Act (ACA) has increased insurance coverage. We provide the first comprehensive assessment of these provisions' effects, using the 2012-2015 American Community Survey and a...

The Affordable Care Act (ACA) aimed to achieve nearly universal health insurance coverage in the United States through a combination of insurance market reforms, mandates, subsidies, health insurance exchanges, and Medicaid expansions, most of which took effect in 2014. This paper estimates the...

The steady state general equilibrium and welfare consequences of health insurance reform are evaluated in a calibrated life-cycle economy with incomplete markets and endogenous labor supply. Individuals face uncertainty each period about their future health status, medical expenditures, labor...

This paper provides empirical evidence of Medicaid crowd out of demand for private long-term care insurance. Using data on the near- and young-elderly in the Health and Retirement Survey, our central estimate suggests that a $10,000 decrease in the level of assets an individual can keep while...

We use a combination of administrative and survey data to estimate the fraction of individuals newly enrolled in public health coverage (Wisconsin's combined Medicaid and CHIP program) that had access to private, employer-sponsored health insurance at the time of their enrollment and the...

Most non-elderly Americans purchase insurance through their employers, which sponsor a limited number of plans. We estimate how much employees would be willing to pay for the right to apply their employer subsidy to the plan of their choosing. We make use of a proprietary dataset containing...
