The Long-Run Effects of Childhood Insurance Coverage: Medicaid Implementation,
Adult Health, and Labor Market Outcomes
       November 2016.
       Appendices available here.

This paper exploits the original introduction of Medicaid (1966-1970) and the federal mandate that states cover all cash welfare recipients to estimate the effect of childhood Medicaid eligibility on adult health, labor supply, program participation, and income. Cohorts born closer to Medicaid implementation and in states with higher pre-existing welfare-based eligibility accumulated more Medicaid eligibility in childhood but did not differ on a range of other health, socioeconomic, and policy characteristics. Early childhood Medicaid eligibility reduces mortality and disability and, for whites, increases extensive margin labor supply, and reduces receipt of disability transfer programs and public health insurance up to 50 years later. Total income does not change because earnings replace disability benefits. The government earns a discounted annual return of between 2 and 7 percent on the original cost of childhood coverage for these cohorts, most of which comes from lower cash transfer payments.

This paper provides new evidence that Medicaid's introduction reduced mortality rates among nonwhite infants and children in the 1960s and 1970s. Medicaid required states to cover all cash welfare recipients, which induced substantial cross-state variation in the share of children immediately eligible for the program. Before Medicaid, higher- and lower eligibility states had similar public insurance use and child mortality rates. At implementation, Medicaid eligibility for nonwhite children ranged across states from 5 to 33 percent and, for white children, from 0.5 to 10 percent. After Medicaid implementation, public insurance utilization increased and mortality fell more rapidly among nonwhite children and infants in high-Medicaid-eligibility states. My estimates suggest that the introduction of Medicaid can account for eight percent of the decline in nonwhite child mortality and fifteen percent of the reduction in the racial gap in child mortality between 1965 and 1980.

The War on Poverty's Experiment in Public Medicine: Community Health Centers
and the Mortality of Older Americans (with Martha Bailey)

This paper uses the rollout of the first Community Health Centers (CHCs) to study the longer-term health effects of increasing access to primary care. Within ten years of their establishment, CHCs are associated with reductions in age-adjusted mortality rates of almost 2 percent--effects driven by those 50 and older. The implied 7 to 9 percent decrease in one-year mortality risk among beneficiaries amounts to 20 to 28 percent of the 1966 poor/non-poor mortality gap for this age group. Large effects for those 65 and older suggest that increased access to primary care has longer-term benefits, even for populations with near universal health insurance.
