I am the Class of 1967 Associate Professor of Business in the Marketing Division at Columbia Business School. My research interests are primarily in empirical industrial organization, where I study the dynamics of demand and pricing in high-tech markets, product innovation and replacement, advertising, and new product introduction. More recently I have also started to study the advertising decisions of political candidates. I teach an elective course on Pricing Strategy for MBA and Executive MBA students.
One industry that I find particularly fascinating is the PC microprocessor market, effectively composed of Intel and AMD. In one paper, I focus on the consumer's perspective and study the dynamics of replacement cycles for processors, which I view as a close proxy for a computer. In a second paper, joint with Ron Goettler, we seek to quantify the benefits of competition in the industry, comparing current outcomes with an alternative model that treats Intel as a monopolist.

I am a co-organizer of the Columbia-Duke-UCLA Workshop on Quantitative Marketing and Structural Econometrics. The next workshop will likely be held in the summer of 2013.
