We study sequential and single-round uniform-price auctions with affiliated values. We derive symmetric equilibrium for the auction in which k1 objects are sold in the first round and k2 in the second round, with and without revelation of the first-round winning bids. We demonstrate that...

Information aggregation, a key concern for uniform-price, common-value auctions with many bidders, has been characterized in models where bidders know exactly how many rivals they face. A model allowing for uncertainty over the number of bidders is essential for capturing a critical condition...

Economic experiments conducted in laboratories employing an induced-values methodology can report on allocative efficiencies observed. This methodology is limited by requiring the experimenter to know subjects' motivations, an impossibility in field experiments. Allocative efficiency implies a...

Laboratory experiments reporting on shortfalls from allocative efficiency of allocation mechanisms depend on the induced-values methodology, which cannot be extended to the field. Harstad [2011] proposes to observe efficiency of allocation mechanisms without knowing motivations via behavior in...

We offer a closer look at screening by graduate admissions committees in their selection of student applicants, and at applicants' strategic behavior given screening methods. Essentially, a signaling game takes place between student applicants seeking to signal ability and admissions committees...

We analyze the preferences of a risk-averse seller over the class of "standard" auctions with symmetric and risk-neutral bidders. Assuming that buyers' private signals are independently distributed, we find that a sealed-bid first-price auction with an appropriately set reserve price is...

We consider a model of search when the distribution of prices (wages) is unknown. The effect of changing the objective function from minimizing expected cost to maximizing expected utility is examined.
