This project will provide the first estimates of whether, and to what degree, public policy can meaningfully disrupt the persistence of poor health and health disparities across generations. We focus attention on the effect of the Earned Income Tax Credit (EITC) on intergenerational health mobility as the EITC is one of the largest and possibly most effective anti-poverty programs in the United States (US). Intergenerational mobility essentially measures equality of opportunity – a vision embraced by many Americans – by quantifying the expected welfare of children relative to their parents. Equality of opportunity would posit that children’s outcomes ought not be shaped by their parent’s characteristics. On the contrary, children would have the opportunity to shape their own destiny unencumbered by the circumstances of their parents. In the US, research identifies intergenerational persistence (the converse of mobility) in health and socioeconomic status that varies by race/ethnicity and place – a clear departure from the ideal of equal opportunities. Health could be a unique characteristic subjected to clear genetic influences that would naturally persist across generations; however, research clearly identifies non-genetic components in intergenerational health persistence that opens the door to public policy feasibly ameliorating health opportunity. Because the EITC’s impacts and/or intergenerational health mobility is patterned by marital status, sex, and race/ethnicity, we also examine whether the EITC disproportionately affects health mobility for disadvantaged groups and investigate optimal timing of benefit receipt in childhood. Using more than 11,000 parent-child pairs in the Panel Study of Income Dynamics, we estimate the effect of the EITC on three established measures of intergenerational health mobility: intergenerational persistence, upward, and downward health mobility (i.e., the expected health of children whose parents are in relatively poor or good health, respectively). We distinguish our study from the often-descriptive intergenerational mobility literature by employing a plausibly exogenous identification strategy to determine the effect of EITC on health mobility. Eligibility for the EITC is based on the number of dependent children in the household. Benefit generosity and eligibility however is, and has been, actively changing at the federal- and state-level since its inception in 1975. It is this variation that we leverage (the number of children in the household, state of residence, and time) to produce estimates of the EITC’s effect on health mobility. Due to the endogeneity of eligibility and take-up at the individual level, we assign each child the maximum EITC benefit afforded to children in their household type regardless of actual or observed EITC receipt, health, or income. Estimates are therefore reflective of the intent to treat. Results could provide actionable pathways for federal and state policymakers evaluati...
