Consider an auction in which $k$ identical objects are sold to $nk$ bidders who each have a value for one object which can have both private and common components to it. Private information concerning the common component of the object is not exogenously given, but rather endogenous and bidders...

We analyze competitive pressures in a sequence of auctions with a growing number of bidders, in a model that includes private and common valuations as special cases. We show that the key determinant of bidders' surplus (and implicitly auction revenue) is how the goods are distributed. In any...

Economic theory is often abused in practical policy-making. There is frequently excessive focus on sophisticated theory at the expense of elementary theory; too much economic knowledge can sometimes be a dangerous thing. Too little attention is paid to the wider economic context, and to the...

Part ownership of a takeover target can help a bidder win a takeover auction, often at a low price. A bidder with a ``toehold'' bids aggressively in a standard ascending auction because its offers are both bids for the remaining shares and asks for its own holdings. While the direct effect of a...

We generalize the War of Attrition model to allow for N + K firms competing for N prizes. Two special cases are of particular interest. First, if firms continue to pay their full costs after dropping out (as in a standard-setting context), each firm's exit time is independent both of K and of...

We compare the most common methods for selling a company or other asset when participation is costly: a simple simultaneous auction, and a sequential process in which potential buyers decide in turn whether or not to enter the bidding. The sequential process is always more efficient. But...

This book is a non-technical introduction to auction theory; its practical application in auction design (including many examples); and its uses in other parts of economics. It can be used for a graduate course on auction theory, or – by picking selectively – an advanced...

We propose a new, easy-to-implement, class of payment rules, "Reference Rules", to make core-selecting package auctions more robust.  Small, almost-riskless, profitable deviations from "truthful bidding" are often easy for bidders to find under currently-used payment rules.  Reference Rules...

I describe a new static (sealed-bid) auction for multiple substitute goods.  As in a two-sided simultaneous multiple round auction (SMRA), bidders bid on multiple assets simultaneously, and bid-takers choose supply functions across assets.  The auction yields more efficiency, revenue,...
