We use a linear probability model with interactions and a switching probit model (SPM) to estimate heterogeneous effects of Medicaid expansions on Medicaid take-up, private insurance coverage and crowd-out. Specifically, we estimate: i) LATEs; ii) ATETs for the currently eligible; and iii) ATETs...

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...

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...

There is continuing controversy about the extent to which publicly insured children are treated differently than privately insured children, and whether differences in treatment matter. We show that on average, hospitals are less likely to admit publicly insured children than privately insured...

to low income women and children, has expanded dramatically over the past decade. This expansion provides a `natural laboratory' for learning about the effect of public health insurance eligibility on insurance coverage, health utilization, and health outcomes. This paper provides an overview of...

Public health insurance programs comprise a large share of federal and state government expenditures. Although a sizable literature analyzes the effects of these programs on health care utilization and health outcomes, little prior work has examined the long-term effects and resultant health...

Of the ten million uninsured children in 1996, nearly half were eligible for Medicaid, the public health insurance program for poor families, but not enrolled. In response, policy efforts to improve coverage have shifted to increasing Medicaid take-up among those already eligible rather than...

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...

The purpose of this paper is to examine issues related to the coverage of preventive care under national health insurance. Four specific kinds of medical care services are included under the rubric of preventive care: prenatal care; pediatric care, dental care, and preventive physicians' services...

During the 1990s many states extended Medicaid eligibility to low-income parents who were not receiving welfare. We evaluate the effects of those expansions on health insurance coverage. To account for unobservable differences between expansion states and non-expansion states that may be...
