The chapters in this dissertation investigate how the design of public health insurance programs affects the behavior of individuals and whether absent the availability of formal insurance systems, individuals in a family act as informal insurance.The first chapter studies how Medicare and Medicaid - the two largest public health insurance programs in the United States - jointly shape patients' access to healthcare and healthcare spending. Specifically, I estimate the effect of gaining additional Medicaid coverage for Medicare beneficiaries on healthcare utilization. While dual coverage eliminates out-of-pocket costs, thereby increasing demand for healthcare, I identify a countervailing force: providers are less willing to treat dual patients due to lower reimbursement rates and higher administrative burdens associated with Medicaid. Using variation from a substantial expansion in dual-Medicaid eligibility in the state of Connecticut, I find that dual enrollment increases patients' total health care utilization by 51 percent, and that much of this increase is driven by a higher use of the emergency department. At the same time, dual enrollment leads to a 24 percent decline in the number of outpatient physician visits, especially for preventive care. I show that the decline in outpatient care is concentrated among providers with a low share of Medicaid patients. Thus, my findings demonstrate the unintended consequences of policies that increase enrollment in dual-Medicaid among patients without changing provider side constraints regarding their willingness to treat Medicaid patients.The second chapter (Duggan et al., 2021) examines how a major healthcare policy affected the working behavior of older populations. The Affordable Care Act (ACA) not only changed the landscape of health insurance coverage in the United States, but also affected the relationship between working decisions and health insurance. In this paper, we estimate the impact of the ACA on the near-elderly (ages 60-64) in the five years after the implementation of its key provisions in early 2014. We exploit variation across geographic areas in the pre-existing level of uninsurance and use 65-69 year olds, whose insurance coverage was unaffected by the ACA, as a withinregion control group. Our findings indicate that the ACA increased health insurance coverage among the near elderly by 4.5 percentage points and reduced their labor force participation rate by 0.6 percentage points.The third chapter (Arrieta and Li, 2023) characterizes the role of informal insurance channels within a family in mitigating the consequences of adverse health events on families. We seek to understand how the labor market decisions of the family adjust in response to plausibly exogenous health shocks. Family members might work less to provide caregiving, or work more in response to medical expenditures and loss of income by the ill individual. We use records of emergency department (ED) visits and hospitalizations to empirically determine the size of these effects. Using ED events we find evidence of intra-family insurance. By exploring how insurance varies by the severity of the health shock, we find that family labor supply responses decrease as the caregiving need increases.
