I provide quasi-experimental evidence on the effect of WIC on birth outcomes using policy variation created by adjunctive eligibility, which allows expansions in Medicaid or SNAP eligibility to affect WIC eligibility. I employ the ‘Difference in differences’ estimation strategy to identify the effects of WIC and Medicaid separately. The results show that a one percentage point increase in WIC eligibility increases average birth weight by 0.495g, which corresponds to an estimated treatment on the treated effect of 23.6g. WIC also reduces the incidence of Small for Gestational Age (SGA) by 0.021 percentage points which corresponds to a treatment on the treated effect of 10.4%. For Medicaid, a one percentage point increase in Medicaid eligibility reduces the incidence of very low birth weight by 0.002 percentage points and preterm birth by 0.015 percentage points. I find little evidence that there is a strong causal link between WIC and low birth weight or preterm birth; however, most literature on WIC found a positive causation. JEL codes: H51, I10, I13, I18

We investigate whether state-specific health insurance parity laws for substance use disorder (SUD) treatment reduce traffic fatalities. Parity laws compel private insurers to cover SUD treatment more generously. We employ 26 years of administrative data from the Fatality Analysis Reporting System coupled with a differences-in-differences design to study this question. Our findings indicate that passage of a parity law is associated with a 7.6 to 8.2% reduction in traffic fatality rates. These findings suggest that government regulations requiring insurers to cover SUD treatment can significantly improve traffic safety, possibly by reducing the number of impaired drivers on roadways.
