In addition to traditional forms of private and public medical insurance, two other large programs help pay for costs associated with ill health. In 2007, Workers Compensation (WC) insurance provided $55.4 billion in medical care and cash benefits to employees who are injured at work or contract...

We analyze Medicare Part D's net effect on elderly out-of-pocket (OOP) costs and use of prescription drugs using a dataset containing 1.4 billion prescription records from Wolters Kluwer Health (WKH). These data span the period December 2004-December 2007 and include pharmacy customers whose age...

The continued interest in public insurance expansions as a means of covering the uninsured highlights the importance of estimates of "crowd-out", or the extent to which such expansions reduce private insurance coverage. Ten years ago, Cutler and Gruber (1996) suggested that such crowd-out might...

Motivated by widely publicized concerns that there are "too many" plans, we structurally estimate (and validate) an equilibrium model of the Medicare Part D market to study the welfare impacts of two feasible, similar-sized approaches for reducing choice. One reduces the maximum number of firm...

This paper tests whether income affects the body weight and clinical weight classification of elderly Americans using a natural experiment that led otherwise identical retirees to receive significantly different Social Security payments based on their year of birth. We exploit this natural...

We study the impact of the 65-percent federal health insurance premium subsidy, which aimed to help unemployed workers retain coverage and was in effect from February 2009 to May 2010 through the American Recovery and Reinvestment Act (ARRA). In doing so, we also estimate the price elasticity of...

Despite the high levels of marital disruption in the United States, and substantial reliance on family-based health insurance, little research is available on the consequences of marital disruption for insurance coverage among men, women, and children. We address this shortfall by examining...

This paper explores the effects of public health insurance expansions on hospitals' decisions to adopt medical technology. Specifically, we test whether the expansion of Medicaid eligibility for pregnant women during the 1980s and 1990s affects hospitals' decisions to adopt neonatal intensive...

The Affordable Care Act of 2010 expanded coverage to young adults by allowing them to remain on their parent's private health insurance until they turn 26 years old. While there is evidence on insurance effects, we know very little about use of general or specific forms of medical care. We study...

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...
