I am a Professor of Economics at UC-Davis, chair of the steering committee of the All-UC Group in Economic History, and a Research Associate of the Center for Poverty Research at Davis. My main current research is on the history and nature of social mobility, investigated using the status information content of surnames and its rate of change over time. Using such methods we can estimate rates of social mobility as early as 1300 for England, and 1700 for Sweden. But I still also study long run economic growth, the wealth of nations, with particular focus on the economic history of England and India.
