The most important issues in auction design are the traditional concerns of competition policy - preventing collusive, predatory, and entry-deterring behaviour. Ascending and uniform-price auctions are particularly vulnerable to these problems, and the Anglo-Dutch auction - a hybrid of the...

There were enormous differences in the revenues from the European "third generation" (3G, or "UMTS") mobile-phone license auctions, from 20 Euros per capita in Switzerland to 650 Euros per capita in the U.K., though the values of the licences sold were similar. Poor auction designs in some...

I suggest explanations for the apparently puzzling bidding in the year 2000 British and German 3G telecom auctions. Relative-performance maximisation may have been important, but the outcome of the British auction seems to have been efficient. This paper bundles my comments on two papers...

We usually assume increases in supply, allocation by rationing, and exclusion of potential buyers will never raise prices. But all of these activities raise the expected price in an important set of cases when common-value assets are sold. Furthermore, when we make the assumptions needed to rule...

This paper, forthcoming in Journal of Economic Surveys, provides an elementary, non-technical, survey of auction theory, by introducing and describing some of the critical papers in the subject. (The most important of these are reproduced in a companion book, The Economic Theory of Auctions,...

We use a classroom game, the Wallet Game, to show that slight asymmetries between bidders can have very large effects on prices in standard ascending (i.e. English) auctions of common-values objects. Examples of small asymmetries are a small value advantage for one bidder or a small ownership of...
