Millions of unauthorized Mexican immigrants live and work in the United States. Their numbers are large compared to earlier waves of illegal migration to the United States and relative to Mexico’s population. The scale of illegal migration has, in turn, provoked intense concerns about its consequences for the United States as well as deep controversy over the proper policy responses.

Please join us as Professor Gordon H. Hanson addresses the economic and social factors that influence the flow of illegal migrants from Mexico. Professor Hanson will also consider evidence on the effectiveness of policies that regulate the cross-border flow of illegal migrants and their access to U.S. jobs. L. Alan Winters, a distinguished scholar in trade and migration issues, will comment on Hanson’s remarks. AEI’s Steven J. Davis will moderate.
