I have research and teaching interests in emerging markets, innovation, product design and pricing. I co-teach an MBA elective course on "Catching the Growth Wave in Emerging Markets," and a PhD seminar on "Mathematical Models in Marketing."
I am presently working on research examining policy and strategy issues concerning organized retailing in India. A related paper, coauthored with Prof. Jagdish Bhagwati, is available here.
I have recently examined the pricing and choice of package sizes for products that deteriorate over time. Part of the motivation for this research was to understand the economics of single-serve package sizes in emerging markets. I have also recently worked on problems concerning multi-part pricing, optimal commercial scheduling in television shows, and the design and pricing of durable goods when consumers differ in usage rates, and products become obsolete and deteriorate over time and with use.
I have an ongoing interest in problems concerning the structure of non-compensatory preferences. Several of my recent papers in this line of work describe generalizations and variants of non-compensatory preference rules (e.g., subset conjunction, binary lexicographic), present their mathematical representations, and propose probabilistic and non-probabilistic methods for inferring these rules from choice, consideration or rank order data
