In this paper, we re-examine the question of crowd out among children. Our primary contribution is the use of longitudinal data. These data allow us to identify several groups of children depending on whether their eligibility for Medicaid was affected by the eligibility expansions, and to...

Basic economic theory suggests that health insurance coverage may cause a reduction in prevention activities, but empirical studies have yet to provide much evidence to support this prediction. However, in other insurance contexts that involve adverse health events, evidence of ex ante moral...

This paper studies the accuracy of reported Medicaid coverage in the Survey of Income and Program Participation (SIPP) using a unique data set formed by matching SIPP survey responses to administrative records from the State of California. Overall, we estimate that the SIPP underestimates...

Increased availability of public health insurance for children has led to two potentially contradictory concerns for public policy: that expanded availability of public insurance may lead families to decline private insurance and that additional public coverage may not reach many uninsured...

This article examines the impact of the Affordable Care Act Medicaid expansion in Michigan, the Healthy Michigan Program (HMP), on the financial well-being of new Medicaid enrollees. Our analysis uses a dataset on credit reports matched to administrative data on HMP enrollment and use of health...

This paper analyzes the effect of Medicaid eligibility expansions on the health insurance coverage of women giving birth and on the use of prenatal care and infant health, controlling for year and state effects and state-specific trends that may be correlated with expansions in Medicaid...

Despite considerable research, there is little consensus about the impact of Medicaid eligibility expansions for low-income children. In this paper, I reexamine the expansions' impact on Medicaid take-up and private insurance "crowd-out." Focusing on the most influential estimates of the...

Using data from the 1988-1996 Current Population Surveys (CPS), we re-examine the evidence presented in Yelowitz (1995) showing that expansions in Medicaid eligibility for children were associated with increased labor force participation and reduced participation in Aid to Families with...

This paper exploits the discrete nature of the eligibility criteria for two major federal expansions of Medicaid to measure the effects on Medicaid coverage, overall health insurance coverage, and the probability of visiting a doctor. The '100 percent' expansion, effective in 1991, extended...

In this study, we examine the effects of Medicaid managed care (MMC) on prenatal care utilization and infant health. We obtain separate estimates of the effect of primary care case management (PCCM) managed care programs and HMO managed care plans on prenatal care utilization, birth weight, and...
