This paper studies the design of health insurance with ex post moral hazard, when there is imperfect competition in the market for the medical product. Various scenarios, such as monopoly pricing, price negotiation or horizontal differentiation are considered. The insurance contract specifies...

We study the health insurance and labor market implications of the recent Affordable Care Act (ACA) provision that allows dependents to remain on parental policies until age 26 using data from the Survey of Income and Program Participation (SIPP). Our comparison of outcomes for young adults aged...

We present and empirically implement an equilibrium labor market search model where risk averse workers facing medical expenditure shocks are matched with firms making health insurance coverage decisions. Our model delivers a rich set of predictions that can account for a wide variety of...

The Affordable Care Act's taxes, subsidies, and regulations significantly alter terms of trade in both goods and factor markets. We use a multi-sector (intra-national) trade model to predict and quantify consequences of the Affordable Care Act for the incidence of health insurance coverage and...

The Affordable Care Act (ACA) will dramatically alter health insurance markets and the sources through which individuals obtain coverage. As the ACA is implemented, it is essential to monitor the intended and the unintended consequences of these regulations. To evaluate the changes in health...

Most private sector workers with employer-provided health insurance have a strong incentive to continue working until Medicare eligibility in order to maintain group health coverage. However, most government employees have access to retiree health coverage, which allows them access to group...

This paper studies regulated health insurance markets known as exchanges, motivated by their inclusion in the Affordable Care Act (ACA). We use detailed health plan choice and utilization data to model individual-level projected health risk and risk preferences. We combine the estimated joint...

This paper illustrates the impact of moral hazard for estimating relative rates of underinsurance and to present an adjustment method to correct for this source of bias. Individuals or households are often classified as underinsured if out-of-pocket spending on medical care relative to income...

Few studies have addressed how use of care may vary over the course of an episode of being uninsured or across uninsured episodes of varying duration. This research models the probability that an uninsured individual has (a) any medical expenditures or charges, and (b) any office-based visit...

Some states have not adopted the Affordable Care Act (ACA) Medicaid expansions due to concerns that the expansions may impair access to care and utilization for those who are already insured. We investigate such negative spillovers using a large panel of Medicare beneficiaries. Across many...
