I am an economist working at the interstice of economics, political science, and international relations. My book, "Avoiding the Apocalypse: the Future of the Two Koreas," won the prestigious Ohira Memorial Prize. My recent books are "Witness to Transformation: Refugee Insights into North Korea" (co-authored with Stephan Haggard), and "Arab Economies in a Changing World" (co-authored with Howard Pack). In addition to these (and other) books I have written many scholarly articles on isues such as international economics, US trade policy, and the economies of the Asia-Pacific region, as well as op-eds for publications such as Newsweek International, the International Herald Tribune, the Financial Times, and the Washington Post. I have served as an occasional consultant to organizations such the National Intelligence Council and have testified before the US Congress on numerous occasions.
