Evaluations of changes to the Medicaid program have focused on increases in the generosity of income cutoffs for Medicaid eligibility. Previous research shows that despite dramatic increases in the number of births paid for by the Medicaid program, women often enroll in Medicaid at the point of...

We analyze the effects of the COVID-19 pandemic on state and local government finances, with an emphasis on health spending needs and the role of the Medicaid program. We arrive at three conclusions. First, we find that nationwide, and over the entirety of the federal budget window, the enhanced...

Health insurance may play an important role not only in immediate access to care but in the management of chronic disease, which would have implications for long-run care needs as well as health outcomes. Such causal connections are often difficult to establish, but we use Oregon's 2008 Medicaid...

State governments face the classic "make or buy" decision for the provision of Medicaid services. Over the past two decades, the majority of states have outsourced the provision of social health insurance through Medicaid Managed Care (MMC) programs. These programs have been extensively studied...

The regulated insurance exchanges set up in the Affordable Care Act (ACA) were designed to deliver affordable, efficient health coverage through private insurers. It is crucial to study the complex industrial organization (IO) of these exchanges in order to assess their impacts to date, during...

We study a 2008 policy reform in which Medicare revised its hospital payment system to better reflect patients' severity of illness. We construct a simulated instrument that predicts a hospital's policy-induced change in reimbursement using pre-reform patients and post-reform rules. The reform...

Interactions between redistributive policies can confront low-income households with complicated choices. We study one such interaction, namely the relationship between Medicaid eligibility thresholds and the minimum wage. A minimum wage increase reduces the number of hours a low-skilled...

Social Security Disability Insurance (DI) awards rise in recessions and fall in expansions, especially for older adults. Using Medicare administrative data for DI entrants between 1991 and 2015, we provide new evidence on the health of DI recipients who enter at different ages and points in the...

In government-sponsored health insurance, subsidy design affects market outcomes. First, holding premiums fixed, subsidies determine insurance uptake and average cost. Insurers then respond to these changes, adjusting premiums. Combining data from the first four years of the California ACA...

Hospitals face large and variable costs from treating indigent care patients. Two methods of "reinsuring" hospitals against these costs are providing these patients with insurance and directly providing hospitals with supplemental payments to cover the expected costs of treating the indigent....
