Breaking Barriers: The Impact of Employer Exposure to Immigrants

We study how exposure of employers to immigrants, both at the market and at the individual firm level, mitigates immigrant-native disparities. We use administrative employee-employer matched data from Portugal, which provides a unique setting given that it experienced almost no immigration until the early 2000s followed by substantial immigration waves. Focusing on the evolution of market wages across successive immigration cohorts, we find that increased employer exposure to immigrant groups can account for up to 25% of the wage convergence between immigrants and natives over the last two decades. We also document that individual-level exposure of firms to immigrants plays an important role, influencing future hiring and remuneration of immigrants. Our results provide new insights into how barriers to hiring different worker groups shape economic inequality, with novel implications for immigration policies.
