South–south migration and female labor supply in the Dominican Republic.

This article examines the impact of female immigration—predominantly low-educated Haitian women—on the labor supply of native women in the Dominican Republic (DR) from 2003 to 2016. Using individual-level data and a novel exposure measure based on historic immigrant settlement patterns combined with annual inflows, the study finds that female immigration decreases hours worked and earnings among low-skilled native women, indicating increased labor market competition. Conversely, it is associated with increased hours worked by high-skilled native women with family dependents, likely due to greater availability and lower prices of domestic services. These findings contrast with evidence from developed countries and highlight the importance of understanding migration's heterogeneous effects in developing country contexts to inform policies supporting vulnerable native workers and migrant integration.
