Three essays on migration and immigration policy

By Thomas Pearson

This dissertation consists of three chapters concerning migration and immigration policy. The first chapter studies how increased U.S. deportations affect Mexican labor markets using variation in migrant networks and Secure Communities (SC), a policy which expanded local immigration enforcement. I show that in the short run, deportations increase return migration and decrease monthly earnings for local Mexicans with less than a high school degree. Deportations also increase net outflows within Mexico and emigration to the U.S. The negative short run effects are not driven by falls in remittance income or increases in crime as deportations increase both the share of households receiving remittances and the total amount received and they do not affect homicide rates. The results instead point to increased labor market competition as a result of return migration. Lastly, I show that the negative short run effects of this labor supply shock are larger in localities with worse infrastructure and less access to the financial sector. These results help explain the large negative effects on earnings as many migrants return to less developed regions where these frictions are prevalent. The second chapter studies how immigration status affects crime reporting and victimization. I focus on Deferred Action for Early Childhood Arrivals (DACA), a policy that temporarily protects youth from deportation and provides work authorization. For identification, I compare likely undocumented immigrants around the policy's age eligibility cut-off over time. DACA eligibility of the victim increased the likelihood that the crime was reported to the police, which is consistent with DACA reducing fears of deportation. DACA eligibility also decreased victimization rates for women. Overall, the results suggest that immigrant legalization increases engagement with police and reduces the likelihood of victimization. …
