Early Effects of the 2010 Affordable Care Act Medicaid Expansions on Federal Disability Program Participation
NBER Working Paper No. 22531
We test whether early Affordable Care Act (ACA) Medicaid expansions in Connecticut (CT), Minnesota (MN), California (CA), and the District of Columbia (DC) affected SSI applications, SSI and DI awards, and the number of SSI and DI beneficiaries. We use a difference-in-difference (DD) approach, comparing SSI/DI outcomes pre and post each early Medicaid expansion (“Early Expanders”) to SSI/DI outcomes in states that expanded Medicaid in January 2014 (“Later Expanders”). We also use a synthetic control approach, in which we examine SSI/DI outcomes before and after the Medicaid expansion in each Early Expander state, utilizing a weighted combination of Later Expanders as a comparison group. In CT, the Medicaid expansion is associated a statistically significant, 7 percent reduction in SSI beneficiaries; this finding is consistent across the DD and synthetic control methods. For DC, MN and CA, we do not find consistent evidence that the Medicaid expansions affected disability-related outcomes.
