Immigration Enforcement Policies, the Economic Recession, and the Size of Local Mexican Immigrant Populations

This article relies on local area variation in immigration policies, specifically the local implementation of the 287(g) program, and economic conditions to estimate their impact on changes in the size of local Mexican immigrant populations between 2007 and 2009. The author also investigates the impact of the 287(g) program on the employment prospects of low-skilled native black and white workers. The study finds that outside of four influential outliers (Dallas, Los Angeles, Riverside, and Phoenix), there is no evidence that the 287(g) program impacted the size of the Mexican immigrant population. In addition, there is no evidence that immigration enforcement policies mitigated the negative impact of the economic recession on the native population, even in the four outliers where the program was strongly enforced. The author highlights the limited efficacy of immigration enforcement as a way to resolve the issue of the undocumented immigrant population and for altering the employment opportunities of native workers.
