I am assistant professor in Economics at George Mason University and a senior scholar at the Mercatus Center where I am a member of the F. A. Hayek Program for Advanced Study in Philosophy, Politics and Economics.   My main area of research is economic history. I obtained my PhD in Economics from the University of Oxford.

In addition to the academic work you can find on this website you can also links to a couple of guest posts I wrote for Marginal Revolution on the historical roots of Africa poverty, European city states, taxes and economic growth, and the relationship between secure property rights and economic growth.   An accessible column discussing my recent work on Jewish expulsions is available here. 

I am the current organizer of the Public Choice Seminar at the Center for Public Choice. Together with Noel Johnson I help to run the Economic History Workshop at George Mason University. Details are available here.
