This document summarizes Michel Boudreaux's dissertation research on the long-term effects of exposure to Medicaid in early childhood. The study uses variation in Medicaid adoption across states and over time to examine the impact on adult health and economic outcomes. The results show that exposure to Medicaid in early childhood significantly decreases the prevalence of adult chronic health conditions for individuals from low-income families, but does not find significant effects on long-term economic status. This suggests that providing health insurance early in life produces lasting health benefits for children from disadvantaged backgrounds.
