Immigration Enforcement and Origin Country Labor Markets

Abstract This paper studies how increased immigration enforcement in the destination country impacts labor markets in the origin country. Using variation in Mexican migrant networks and Secure Communities (SC), a policy which expanded local immigration enforcement, I show that the deportation of Mexican migrants from the U.S. increases return migration to Mexico and decreases monthly earnings for workers there. The negative earnings effects are largest for workers most similar to return migrants in terms of their demographics, occupations, and employment types, and are consistent with increased labor market competition.
