Immigrant Rights Expansion and Local Integration: Evidence from Italy

We study how expanding immigrants' rights affects their political and social integration by leveraging Romania's 2007 EU accession, which granted Romanian immigrants in Italy municipal voting and residency rights. Using municipality-level event studies, we find: (1) Enfranchisement increased the election of Romanian-born councilors - especially in competitive races - despite limited changes in candidacy rates. It also increased Romanian turnout, suggesting that electoral gains stem from an expanded voter base. An instrumented difference-in-differences analysis shows this is driven by pre-existing Romanian residents, not new arrivals. (2) Consent to organ donation rose among Romanians post-2007, indicating that the expansion of rights extends to prosocial behavior. (3) Nonetheless, immigrant presence continues to raise support for right-leaning parties and security spending while reducing social spending, highlighting persistent native backlash that outweighs immigrant political influence.
