This paper investigates the effects of health insurance and new antiviral treatments on HIV testing rates among the U.S. general population using nationally representative data from the Behavioral Risk Factor Surveillance Survey (BRFSS) for the years 1993 to 2002. We estimate recursive bivariate...

As policymakers consider expanding insurance coverage for HIV+ individuals, it is useful to ask if insurance has any affect on health outcomes; and, if so, whether public insurance is as efficacious as private insurance in preventing premature deaths among HIV+ patients. Using data from a...

If rational individuals pay the full costs of their decisions about food intake and exercise, economists, policy makers, and public health officials should treat the obesity epidemic as a matter of indifference. In this paper, we show that, as long as insurance premiums are not risk rated for...

The COVID-19 pandemic has forced federal, state and local policymakers to respond by legislating, enacting, and enforcing social distancing policies. However, the impact of these policies on healthcare utilization in the United States has been largely unexplored. We examine the impact of...

Many companies have defined-contribution benefit plans requiring employees to pay the full cost (before taxes) of more generous health insurance choices. Research has shown that employee decisions are quite responsive to these arrangements. What is less clear is how the total compensation...

Innovation policy often involves an uncomfortable trade-off between rewarding innovators sufficiently and providing the innovation at the lowest possible price. However, in health care markets with insurance for innovative goods, society may be able to ensure efficient rewards for inventors and...

We examine provider responses to the Medicare inpatient rehabilitation facility (IRF) prospective payment system (PPS), which simultaneously reduced marginal reimbursement and increased average reimbursement. IRFs could respond to the PPS by changing the total number of patients admitted,...

The prevalence of obesity has been rising dramatically in the U.S., leading to poor health and rising health care expenditures. The role of policy in addressing rising rates of obesity, however, is controversial. Policy recommendations for interventions intended to influence body weight...

Traditional economic models of vaccination assume that agents free-ride on the vaccination decision of others. These models show that private vaccination rates are always below the social optimal and even large subsidies cannot achieve disease eradication. In this paper, we build a model where...

Estimates of the returns to medical care may reflect not only the efficacy of more intensive care, but also unmeasured differences in patient severity or the productivity of health-care providers. We use a variety of instruments that are plausibly orthogonal to heterogeneity among providers as...
