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...

We study a model in which perfectly informed experts offer advice to a decision maker whose actions affect the welfare of all. Experts are biased and thus may wish to pull the decision maker in different directions and to different degrees. When the decision maker consults only a single expert,...

In an incomplete information, common values setting with risk-neutral agents, we consider mechanisms for allocating the assets of a dissolving partnership where the mechanism designer has no information about the distribution of signals of the agents. We find that the divide and choose mechanism...

Two laboratory experiments - one a statistical urn problem, the other a monetary policy experiment - were run to test the commonly-believed hypothesis that groups make decisions more slowly than individuals do. Surprisingly, this turns out not to be true there is no significant difference in...

We study auctions where bidders have independent private values but attach a disutility to the surplus of rivals, and derive symmetric equilibria for first-price, second-price, English, and Dutch auctions. We find that equilibrium bidding is more aggressive than standard predictions. Indeed, in...

John Morgan presents a radical proposal to sell voting rights at the IMF and redistribute power through market mechanisms instead of by formula.

We analyze an oligopoly model of homogeneous product price competition that allows for discontinuities in demand and/or costs. Conditions under which only zero profit equilibrium outcomes obtain in such settings are provided. We then illustrate through a series of examples that the conditions...

We study a model where an employer, trying to fill a vacancy, engages in optimal sequential search by drawing from two subpopulations of candidates who differ in their "discourse systems": during an interview, a minority candidate with a discourse system not shared with the employer conveys a...
