In her research published in the American Economic Review, the Review of Economics and Statistics, the Journal of Human Resources, Health Affairs, and other outlets, Professor Sarah Miller has used quasi-experimental methods to evaluate whether receiving improved access to health care in utero, in early childhood, and throughout childhood improves outcomes in adulthood. Miller and her co-authors have found that children who have received eligibility for health insurance through the Medicaid program have improved outcomes on a number of dimensions, both in terms of health and economic outcomes. Additionally, they found that the children of those children who had better access to healthcare in childhood were healthier at birth. This suggests a cycle in which investing in children's health today can have multigenerational benefits that allow the government to fully recoup the cost of its initial investment in the form of higher tax payments and lower spending on welfare programs. Miller's research has been discussed in numerous high-profile news outlets and has strongly impacted how academics and policymakers view investments in children. Furthermore, her papers have been cited nearly 500 times.
