In this paper, I investigate the outcome of a price competition between two firms, each producing two complementary products. Specifically, I study each firm's decision to coordinate price promotions of its products. Consumers are divided into loyals, who purchase both products from their...

This paper revisits the theory of oligopoly pricing and shows that for a large class of demand and cost functions, a mixed strategy equilibrium necessarily implies that each firm's equilibrium strategy is a discrete distribution over a finite number of prices.

How should price promotion strategies be modified in an emerging market (e.g., India, China) compared to those employed in developed markets (e.g., USA, Canada)? Specifically, how should the presence of middle-class consumers with limited ability to pay, prevalent in an emerging market,...

When nonprofit organizations in the U.S. engage in activities that are "substantially related" to their legal mission they pay no profits taxation, but profit from "unrelated business" (UB) activities is taxed. Since UB activity has no apparent justification other than to generate revenue, we...

In this paper, I modify Varian's [Varian, H.R. (1980). A model of sales, American Economic Review, 70(4), 651-659] model of sales to allow for heterogeneity in consumer preferences. I show that in mixed strategy equilibria each firm charges a finite number of prices. Using this characterization,...
