We model the commercial World Wide Web as a directed graph that emerges as the equilibrium of a game in which utility maximizing websites purchase (advertising) in-links from each other while also setting the price of these links. In equilibrium, higher content sites tend to purchase more...

Consumers cannot purchase a prescription drug without a prescription from a physician, yet many prescription drugs are promoted to consumers with the help of direct-to-consumer (DTC) advertising. In this paper, we propose and test a competitive model of DTC advertising. We find that the brand...

We consider a problem at the interface of auctions and bundling. Our revenue-maximizing seller seeking to auction one unit each of two complements or substitutes in the best-of-three formats: the auction of the bundle, separate auctions of the individual items, and a combinatorial auction. We...

Online retailing boasts two major advantages: convenience of home shopping and easy access to information. In this paper, I argue that these two features have important implications for retailers' channel and advertising decisions. Two major questions are addressed: When should a conventional...

This paper shows that the analysis of Liu et al. (2004) contains a substantive error—the asserted pure-strategy Nash equilibrium leading to their Theorems 1 and 2 is really not an equilibrium. We show that in their model, either pure-strategy Nash equilibria do not exist or, unlike their...

In this paper we examine the issue of balancing media advertising (pull strategy) and trade promotions (push strategy) for manufacturers of consumer packaged goods utilizing a three-stage game theoretic analysis and test model's implications with scanner panel data. We develop a model of two...

This paper analyzes the literature concerning models of endogenous mergers. Traditional models of exogenous mergers analyze mergers as isolated phenomena. However, some empirical facts about M&A don't seem to be explained in this literature. Models of endogenous mergers take into account all...
