Does enhanced illegal immigration enforcement affect the employment of legal migrant workers?

Sari Wang


My thesis examines how enhancing enforcement against unauthorized immigration in the United States impacts the employment patterns of legal migrant workers in undocumented labour intensive sectors. I focused upon a case study of the effects of Arizona Senate Bill 1070 on the hiring of H-2A temporary visa workers in agriculture.

Using a data-driven approach to select a weighted set of control states to simulate counterfactual outcomes, I found that the passage of this law decreased employment of these visa workers in Arizona by 36 per cent.
