A New NBER Book Explores How High-Skilled
Immigrants Affect U.S. Innovation and Productivity


Immigration policy is one of the most contentious public policy issues in the United States today.

High–Skilled Immigration to the United States and Its Economic Consequences, a new NBER book from the University of Chicago Press, goes beyond the traditional question of how the inflow of foreign workers affects native employment and earnings to explore effects on innovation and productivity, wage inequality across skill groups, the behavior of multinational firms, firm-level dynamics of entry and exit, and the nature of comparative advantage across countries.
