Based on the Bernhard Harms Prize Lecture delivered at the Kiel Institute of World Economics on October 31, 2012. Part of the work on this lecture was completed when I was visiting STICERD at the London School of Economics and Centre de Recerca en Economia Internacional (CREI) in Barcelona. I thank both institutions for their hospitality and support. I am grateful to Arnaud Costinot, Elhanan Helpman, Stephen Redding, and Esteban Rossi-Hansberg for their comments and suggestions.
