We analyse the major economic issues raised by the 1997 Tobacco Resolution and the ensuing proposed legislation that were intended to settle tobacco litigation in the United States. By settling litigation largely in return for tax increases, the Resolution was a superb example of a win-win deal....

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...

The condition for when a price control increases consumer welfare in perfect competition is tighter than often realised.  When demand is linear, a small restriction on price only increases consumer surplus if the eleasticity of demand exceeds the elasticity of supply; with log-linear or...

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,...

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...

What should be the West's top priority for climate-change policy?  This article is a revsied 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 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 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.

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 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...
