I am a professor of international economics in the School of International Service at American University in Washington, DC. Previously, I was professor of international economics and director of the Globalisation and Economic Policy Research Centre at the University of Nottingham and I also taught at Clark University. I am best known for exploiting the 19th century opening up of Japan as a natural experiment to provide the first rigorous test of the theory of comparative advantage and the price formulations of neoclassical trade theory.
I have published articles on the theoretical, empirical and historical aspects of international trade in peer-reviewed journals such as the American Economic Review, the Journal of Political Economy and the Journal of International Economics. My research has been funded by the National Science Foundation, the Leverhulme Trust, the British Academy and the Alexander von Humboldt Foundation.
