We study the impact of the Euro on prices charged by online retailers within the EU. Our data spans the period before and after the Euro was introduced, covers a variety of products, and includes countries inside and outside of the Eurozone. After controlling for cost, demand, and market...

The market values of online platforms, such as Yahoo, stem from their ability to monetize the clicks they generate for firms advertising on their sites. We exploit a unique dataset on clicks from one of Yahoo's price comparison sites to estimate the determinants of clicks received by online...

This paper presents theory and experiments to investigate how network architecture influences route-choice behavior by comparing outcomes across several different networks. The network changes we consider are based on abstract examples illustrating the Pigou-Knight-Downs and Braess Paradoxes. We...

Two experiments were conducted to test the common hypothesis that groups make decisions more slowly than individuals. One of these experiments imitates real-life monetary policy decisions. In both cases, the hypothesis is found wanting: groups are not slower than individuals. In both...

We compare expected rent-seeking expenditures and efficiency of simultaneous versus sequential rent-seeking contests. We find that when two risk neutral ex ante identical agents are competing, sequential contests are ex ante Pareto superior to simultaneous contests. We then endogenize the timing...

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,...
