In laboratory experiments bidding in first-price auctions is more aggressive than predicted by the risk-neutral Bayesian Nash Equilibrium (RNBNE) - a finding known as the overbidding puzzle. Several models have been proposed to explain the overbidding puzzle, but no canonical alternative to...

We extent the point-identification result in Guerre, Perrigne, and Vuong (2009) to environments with one-dimensional unobserved auction heterogeneity. We also show a robustness result for the case where the exclusion restriction used for point identification is violated: We provide conditions to...

If managers maximize the payoffs of their shareholders rather than firm profits, then it may be anticompetitive for a shareholder to own competing firms. This is because a manager?s objective function may place weight on profits of competitors who are held by the same shareholder. Recent...

Does advertising help consumers to find the products they need or push them to buy products they don't need? In this paper, we study the effects of advertising on consumer mistakes and quantify the resulting effect on consumer welfare in the market for mortgage refinancing. Mortgage borrowers...

Theory predicts that "common ownership" (ownership of rivals by a common shareholder) can be anticompetitive because it reduces the weight firms place on their own profits and shifts weight toward rival firms held by common shareholders. In this paper we use accounting data from the banking...

The U.S. government guarantees a majority of residential mortgages, which is often justified as a means to promote homeownership. In this paper we use property-level data to estimate the effect of government mortgage guarantees on homeownership, by exploiting variation of the conforming loan...
