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 examined issues pertaining to the advertising decisions of presidential candidates. I teach an elective course on Pricing Strategy for MBA and Executive MBA students.
