Book Description
We conduct a laboratory experiment of second-price sealed bid auctions of a common value good with two bidders. Bidders face three different types of information: common uncertainty (unknown information), private information (known by one bidder) and public information (known by both bidders), and auctions differ on the relative importance of these three types of information. We find that subjects differentiate insufficiently between private and public information and deviate from the theoretical predictions with respect to all three types of information. There is under-reaction to both private and public information and systematic overbidding in all auctions above and beyond the standard winner's curse. The Cursed Equilibrium and Level-k models successfully account for some features of the data but others remain unexplained.

Book Description
An invaluable account of how auctions work—and how to make them work Few forms of market exchange intrigue economists as do auctions, whose theoretical and practical implications are enormous. John Kagel and Dan Levin, complementing their own distinguished research with papers written with other specialists, provide a new focus on common value auctions and the "winner's curse." In such auctions the value of each item is about the same to all bidders, but different bidders have different information about the underlying value. Virtually all auctions have a common value element; among the burgeoning modern-day examples are those organized by Internet companies such as eBay. Winners end up cursing when they realize that they won because their estimates were overly optimistic, which led them to bid too much and lose money as a result. The authors first unveil a fresh survey of experimental data on the winner's curse. Melding theory with the econometric analysis of field data, they assess the design of government auctions, such as the spectrum rights (air wave) auctions that continue to be conducted around the world. The remaining chapters gauge the impact on sellers' revenue of the type of auction used and of inside information, show how bidders learn to avoid the winner's curse, and present comparisons of sophisticated bidders with college sophomores, the usual guinea pigs used in laboratory experiments. Appendixes refine theoretical arguments and, in some cases, present entirely new data. This book is an invaluable, impeccably up-to-date resource on how auctions work--and how to make them work.

Book Description
This dissertation consists of two essays on the topic of bidding in multi-unit common value auction. Essay one examines the role of capacity constraint on the auction results and bidding behavior. We consider a general case where bidders are unconstrained, and a second setting where bidders are capacity constrained. We document downward sloping demand curves for individual bidders. Bidders shade their bids by submitting quantity-price pairs and spreading their bids. The winner's curse is strong in the unconstrained treatment, but we find no evidence of the winner's curse when bidding constraints are imposed. Unconstrained bidders shade bids significantly more and their quantity-weighted prices are much lower than those in the constrained treatment. Interacting with the information structure, the capacity constraint has a significant impact on the auction results including the market clearing price, market efficiency, and the degree of market concentration. We provide evidence that efficient price discovery in multi-unit auctions with diverse information is possible, but careful attention to auction design will make this outcome more likely. Essay two examines how the introduction of a noncompetitive bidding option affects outcomes in a multi-unit uniform-price auction. The experimental design incorporates many of the characteristics of the markets that pertain to the issuance of new equity securities. Important features of the bidding environment include endogenous bidder entry, costly information acquisition, bidders that differ by capacity constraint, and substantial uncertainty with respect to the intrinsic value. We use a standard uniform-price auction as our baseline setting where only competitive bids are accepted. Our results show that introducing the noncompetitive bidding option improves auction performance by increasing revenue and reducing price error. Underpricing is found in both treatments, but is less severe in the presence of the noncompetitive bidding option. The incorporation of this option significantly increases both the small bidder participation rate and allocation, and reduces the incentive for small bidders to free ride by submitting extremely high bids. Under both treatments, information acquisition increases large bidders' profits but proves unprofitable for small bidders, and pricing accuracy is increasing in the rate of information acquisition.

Book Description
We study the equilibrium of second-price auctions with resale when the value of the asset is subject to future state uncertainty. We assume bidders differ in their sensitivities toward each state, resulting in alternating orderings of use values. In both complete and incomplete information settings, equilibrium bids are higher than expected use values, equilibrium bidding functions are non-monotone and convex, with a minimum at the median of type distribution. Under incomplete information, the winner of the auction is unable to infer the type of losing bidder with certainty, which can result in scenarios where she cannot capture all surplus.

Book Description
This book provides a comprehensive introduction to modern auction theory and its important new applications. It is written by a leading economic theorist whose suggestions guided the creation of the new spectrum auction designs. Aimed at graduate students and professionals in economics, the book gives the most up-to-date treatments of both traditional theories of 'optimal auctions' and newer theories of multi-unit auctions and package auctions, and shows by example how these theories are used. The analysis explores the limitations of prominent older designs, such as the Vickrey auction design, and evaluates the practical responses to those limitations. It explores the tension between the traditional theory of auctions with a fixed set of bidders, in which the seller seeks to squeeze as much revenue as possible from the fixed set, and the theory of auctions with endogenous entry, in which bidder profits must be respected to encourage participation.

Book Description
We consider parametric examples of two-bidder private value auctions in which each bidder observes her own private valuation as well as noisy signals about her opponent's private valuation. In such multidimensional private value auction environments, we show that the revenue equivalence between the first and second price auctions breaks down and there is no definite revenue ranking; while the second price auction is always efficient allocatively, the first price auction may be inefficient and the inefficiency may increase as the signal becomes more informative; equilibria may fail to exist for the first price auction. We also show that auction mechanisms provide different incentives for bidders to acquire costly information about opponents' valuation.
