Professor of Economics, Director of Graduate Studies
I am a Professor of Economics at the University of Zurich and Research Fellow at the Centre for Economic Policy Research (CEPR). I hold a BS in Economics from the University of Pennsylvania (1991) and a PhD in Economics from Stanford University (1998). Prior to joining the faculty at Zurich, I held academic positions in the UK and US at the University of Warwick, Duke University, and the University of Arizona. In 2007-2008, I was the Chief Economist at the Federal Communication Commission (FCC), the United States media and communications regulator.
I am an empirical economist specializing in the fields of industrial organization, econometrics, and media economics. Much of my work focuses on "evidence-based policymaking": using data on consumer and firm behaviour to understand the mechanisms generating market outcomes in product (esp. media) markets in order to best design public policies in those markets. I am also interested in empirical models of information, learning, and search, endogenous product characteristics and optimal product choice, and the economic effects of advertising.
