A Deportation Boomerang? Evidence From U.S. Removals to Latin America and the Caribbean

The forced return of migrants is an important part of migration policy toolkits. An increased risk of deportation, politicians argue, will deter subsequent irregular migration. We explore this argument for the case of forced removals from the United States and find that rather than operating as a deterrent for future migrants, this policy had a boomerang effect. The forced return of migrants with a track record of crime generated negative externalities in the form of higher violence in their countries of origin, counteracting the deterrence effect of higher deportation risk. We apply mediation analysis to a panel of Latin American and Caribbean countries and decompose the effect of deportations on emigration into three coefficients of interest: a total effect of deportations on later emigration, an effect of deportations on the mediator variable of violence, and an effect of violence on emigration. We address the endogeneity of our key explanatory variables-deportations and violence-using migrants' exposure to the unequal and staggered implementation of policies intended to facilitate deportations at the level of U.S. states as a source of exogenous variation. We show that migration intentions and asylum requests increase in response to deportation threats. This effect is mediated through increased violence and is strongly driven by dynamics in Central America. Although the total number of apprehensions at the U.S. southern border in response to deportation threats does not show a clear pattern, we observe an increase in the share of unaccompanied minors and the share of entire family units among those apprehended, suggesting a shift in migration strategies and composition.
