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 undergraduate or MBA...

We briefly survey the economics of network effects and switching costs (in 3,400 words). For comprehensive coverage of the same ground see Farrell and Klemperer’s 60,000-word contemporaneous survey, available at www.paulklemperer.org

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...

What should be the West's top priority for climate-change policy? This article is a revised and updated version of my talk to the Potsdam Global Sustainability Symposium (which drafted the "Potsdam Declaration" presented to the 2007 UN Climate Change Conference in Bali).

This paper reviews the part played by economists in organizing the British third-generation mobile-phone licence auction that concluded on 27 April 2000. It raised £22 1/2 billion ($34 billion or 2 1/2% of GNP) and was widely described at the time as the biggest auction ever. We discuss the...

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...

Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in effciency, and gives vendors lucrative ex...

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...

We compare the two most common bidding processes for selling a company or other asset when participation is costly to buyers. In an auction all entry decisions are made prior to any bidding. In a sequential bidding process earlier entrants can make bids before later entrants choose whether to...

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...
