I am a Professor of economics a the University of Wisconsin-Madison, and a research associate at the NBER.

I am interested in the detection and measurement of market power; including questions related to differentiation, collusion, vertical and horizontal mergers, price discrimination, and search frictions. My work covers a wide range of industries: energy, finance and banking, and online retailing. I also study market power in developing countries, looking at the effect of collusion on sanitation in Senegal.
