We model a homogeneous product environment where identical e-retailers endogenously engage in both brand advertising (to create loyal customers) and price advertising (to attract 'shoppers'). Our analysis allows for 'cross-channel' effects; indeed, we show that price advertising is a substitute...

This paper presents theory and experiments to investigate how network architecture influences route-choice behavior. We consider changes to networks that, theoretically, exhibit the Pigou-Knight-Downs and Braess Paradoxes. We show that these paradoxes are specific examples of more general...

We analyze Varian's (1980) Model of Sales, and show that when the number of uninformed consumers increases, prices become less competitive for all consumers. Thus, the influx of uninformed consumers generates a negative externality increasing prices paid by informed consumers.

Many firms divide the price a consumer pays for a good into two pieces---the price for the item itself and the price for shipping and handling. With fully rational customers, the exact division between the two prices is irrelevant---only the total price matters. We test this hypothesis by...

We study, both theoretically and in the lab, the performance of open outcry debt and equity auctions in the presence of both private information and hidden e¤ort in an independent private value setting. We characterize symmetric equilibrium bidding strategies and show that these lead to e¢...

We study optimal contracting under imperfect commitment in a model with an uninformed principal and an informed agent. The principal can commit to pay the agent for his advice but retains decision-making authority. Under an optimal contract, the principal should (i) never induce the agent to...
