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 be held from July 30 to August 1, 2013, at Duke. Note the deadline has been extended until April 26, 2013.
