Klemperer has an engineering degree from Cambridge University, and an MBA and an economics PhD from Stanford University. He was elected John Thomson Fellow and Tutor of St Catherine's College, Oxford in 1984, and a Professorial Fellow of Nuffield College, Oxford in 1995, when he became Edgeworth Professor in succession to Nobel prizewinner James Mirrlees.
He was a Member of the UK Competition Commission from 2001–5. He was elected a Fellow of the Econometric Society in 1994, a Fellow of the British Academy in 1999, and a Foreign Honorary Member of the American Academy of Arts and Sciences in 2005.
His 1985 papers (with Jeremy Bulow and John Geanakoplos) developed the concept – and invented the terminology – of "strategic complements" that is now commonly used in game theory, industrial organisation and elsewhere.
His paper on supply function equilibria (with Margaret Meyer) developed a standard model for the analysis of privatised electricity markets, and has been important in developing the theory of multiunit auctions.
He has also invented new auction designs, including the "Product Mix Auction" that is now in regular use by the Bank of England (currently used monthly). This new auction for differentiated products has similarities to a simultaneous multiple-round auction, but runs instantaneously, is said to be more robust against collusion, and allows sellers, as well as buyers, to specify how the quantities they trade will depend on the auction prices. His other innovations include the Anglo-Dutch auction, and (with Aytek Erdil) Reference-Rule Pricing for package auctions.
He has also worked (with Elizabeth Baldwin) on applying tropical geometry to economics and auctions, including the Product Mix auction.
He was principal auction-theorist designing the UK '3G' mobile-phone license auction that raised £22½ billion in spring 2000 and was far more successful than several parallel exercises on the European continent. The Netherland auction that took place 3 months later raised 1/4 of the revenue per head of population, and the difference has been attributed to the auction design. It has been argued that the UK Treasury owes £15 billion or more to him and Ken Binmore, who led the auction team.
In 2007–2008, he advised the UK and US governments on the financial crisis, and he developed a new form of auction (the Product Mix auction) to help the Bank of England alleviate the liquidity crisis. The Bank Governor, Sir Mervyn King, told the Economist that "The Bank of England's use of Klemperer auctions in our liquidity insurance operations is a marvellous application of theoretical economics to a practical problem of vital importance to financial markets." He subsequently advised other countries' Central Banks.
He participated in the meeting that drafted the Potsdam Memorandum to the 2007 UN Climate Change Conference in Bali; he is on the Environmental Economics Academic Panel to the UK's Department of the Environment (Defra).
