Abstract: In the wake of the Affordable Care Act, some US states expanded Medicaid eligibility to lowincome, working-age adults while others did not. This study investigates whether this divergence induces migration across state borders to obtain Medicaid, especially in border regions. It compares border with interior regions' in-migration in the concerned subgroup before and after the Medicaid expansion in linear probability difference-in-difference and triple difference regression frameworks. Using individual-level data from the American Community Surveys over 2012—2017, this study finds a tendency towards increases in in-migration to expansion states' border regions after the expansion. The odds of having migrated increase by about 34 % in these regions after the Medicaid expansion compared to before and control regions. However, this additional migration increases the number of Medicaid-eligible working-age adults by less than 1.5 % in border regions. If all additional migrants take up Medicaid, the number of Medicaid beneficiaries in these regions increases by approximately 4 %. Thus, the concerned individuals might value Medicaid, but the induced migration appears unlikely to impose meaningful fiscal externalities at the regional level.
