The cost of efforts to expand health insurance coverage to the currently uninsured increases when people who would otherwise purchase private insurance obtain subsidized public coverage. Legislators are increasingly interested in mechanisms that target insurance benefits to those who need them...

Since 2012 the Congressional Budget Office has included an estimate of the market value of government-provided health insurance coverage in its measures of household income. We follow this practice for both public and private health insurance to capture the impact of greater access to...

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...

Many industries, including health insurance, are characterized by a handful of large firms competing against each other in multiple markets. Such overlap across markets, defined as multimarket contact (MMC), may facilitate tacit collusion and thus reduce the intensity of competition. We examine...

This paper presents the first national estimates of the effects of the SCHIP expansions on insurance coverage. Using CPS data on insurance coverage during the years 1996 through 2000, we estimate two-stage least squares regressions of insurance coverage. We find that SCHIP had a small, but...

We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...

In spite of the large expected costs of needing long-term care, only 10-12 percent of the elderly population has private insurance coverage. Medicaid, which provides means-tested public assistance and pays for almost half of long-term care costs, spends more than $100 billion annually on...

Public financing of private health insurance may generate external effects beyond the subsidized population, by influencing the size and bargaining power of health insurers. We test for this external effect in the context of Medicare Part D. We analyze how Part D-related insurer size increases...

We analyze the effects of states' expansions of CHIP eligibility to children in higher income families during 2002-2009 on take-up of public coverage, crowd-out of private coverage, and rates of uninsurance. Our results indicate these expansions were associated with limited uptake of public...
