Jean Tirole Wins Nobel in Economics for Work on Regulation Jean Tirole Wins Nobel in Economics for Work on Regulation
(about 4 hours later)
WASHINGTON — Jean Tirole, a French economist, won the 2014 Nobel Memorial Prize in Economic Science on Monday for his work to improve the regulation of large, powerful companies in industries including banking and communications. WASHINGTON — The French economist Jean Tirole, a student of imperfect markets, has spent decades dissecting the many industries where competition does not fulfill the textbook promise that prices will be low and quality will be high.
The Royal Swedish Academy of Sciences said Mr. Tirole, 61, had contributed to taming such companies by analyzing when and how regulators should constrain their activities and pricing — and when regulators should stand back. Mr. Tirole’s work has helped governments to improve cable television service, to restrict credit card fees and to crack down on harmful monopolies.
Mr. Tirole has helped to show “what sort of regulations do we want to put in place so large and mighty firms will act in society’s interest,” Tore Ellingsen, the chairman of the prize committee, said after the award announcement. And on Monday, it won him the Nobel Memorial Prize in Economic Science.
Mr. Tirole is an economist of imperfect markets. In theory, the push-and-pull of competition keeps prices low and quality high. In reality, monopolies or a few companies dominate many markets. They hold the power to keep prices artificially high, and they often lack incentives to innovate or improve quality. Mr. Tirole’s work has clarified “what sort of regulations do we want to put in place so large and mighty firms will act in society’s interest,” Tore Ellingsen, the chairman of the selection committee, said after the announcement ceremony.
Economists have long recognized that government regulation of such markets could produce better outcomes for society. Mr. Tirole was a pioneer in the application of mathematics, including game theory, to writing those rules. The choice of Mr. Tirole, a professor at the Toulouse School of Economics, comes after the 2008 financial crisis revealed shortcomings in the regulation of banks and other financial firms, and with increasing scrutiny, particularly in Europe, about the market power of technology companies like Google and Apple.
Mr. Tirole, a professor at the Toulouse School of Economics, had long appeared on short lists of likely laureates, and the award was seen as particularly timely in the wake of the 2008 financial crisis, which revealed significant shortcomings in the regulation of the financial system, and amid rising questions about the market power of technology companies like Google and Apple. It is also the second consecutive year that the committee has honored an economist whose work essentially assumes that markets are often inefficient, challenging a widely held view in academia long associated with the University of Chicago economics department.
He received a doctorate in economics from the Massachusetts Institute of Technology in 1981, and he taught there for eight years before returning to France in the early 1990s. Much of his early work was done in collaboration with his mentor, Jean-Jacques Laffont, and more recently with a revolving cast of other economists, depending on the topic. The results are wide ranging. A description released by the prize committee cited 60 different papers. “Jean Tirole, along with others, established a good theoretical foundation for the non-Chicago view of things that markets fail in various ways,” said John Kwoka, a professor of economics at Northeastern University in Boston who specializes in competition and regulation. “It’s important to think hard about the reasons that they fail and it’s important to think hard about the consequences.”
“Jean Tirole is one of the most influential economists of our time,” the prize committee said in its announcement. “Most of all, he has clarified how to understand and regulate industries with a few powerful firms.” Monopolies or a few companies dominate many markets. They hold the power to keep prices artificially high, and they often lack incentives to innovate or improve quality. Cable and electric companies are ready examples in the United States.
His work, beginning in the 1980s, was in part a response to the need for new rules as European governments divested state monopolies, seeking to encourage investment and innovation while preventing predatory profit margins. Economists have long recognized that government regulation of such markets could produce better outcomes for society. Mr. Tirole, 61, is a pioneer in the application of mathematics, including game theory, to devising those rules. His work is largely theoretical, yet it has translated easily to practical use.
Mr. Tirole did not offer a single set of new rules. Rather, he applied a set of general principles to the particulars of each industry to derive the appropriate regulations. His work is also wide ranging. A description of his influence published by the prize committee cited more than 60 papers, an unusually large number.
Joshua Gans, an economist at the University of Toronto, compared Mr. Tirole to Louis Pasteur as the rare example of a laureate whose work has both advanced the theoretical understanding of economics and directly impacted everyday life. Mr. Tirole’s achievement was in “writing prolifically, thinking creatively, covering a lot of territory and adding important nuance in a lot of areas,” said Lawrence J. White, a professor of economics at New York University.
Mr. Gans pointed in particular to Mr. Tirole’s work on the deregulation of communications networks. Homes are generally connected to networks by a single line, owned by a single company. Governments seeking to foster competition can require that company to sell access to its rivals. But the price is crucial. Too high, and consumers will see little competition. Too low, and the company itself will be unable to serve customers at a profit. In effect, if a company sells both iron and goods made from iron, the question is how much should it charge for the iron. His work, beginning in the 1980s, was in part a response to the need for new rules as governments in Europe divested state monopolies, seeking to encourage investment and innovation while preventing windfall profits.
The pricing model developed by Mr. Tirole and Mr. Laffont is the basis of current law in Europe, New Zealand, Australia and other countries. But not in the United States. Mr. Gans said the difference explains why consumers in those other countries enjoy lower prices and better service. Mr. Tirole did not offer a single set of new rules. Rather, he applied a set of general principles to the circumstances of each industry to suggest appropriate policies, often reflecting a nuanced balancing of costs and benefits.
“The alternative is what happens in the U.S. where Comcast doesn’t give access to its competitors so Time Warner has to decide whether to build over the top of Comcast or just to stay out of their markets,” he said. “Had there been access regulation, maybe Time Warner and Comcast would be competing more directly.” Joshua Gans, an economist at the University of Toronto, compared Mr. Tirole with Louis Pasteur as the rare example of a laureate whose work has both advanced theoretical understanding and directly affected daily life.
Another example of the general application of Mr. Tirole’s study of a specific case concerns his work on the credit-card industry in the late 1990s. Credit cards are a “two-sided market,” meaning that the business is in connecting two groups, the credit-card holders and merchants, and profiting from the interaction. Mr. Gans pointed in particular to Mr. Tirole’s work on the deregulation of communications networks. Homes are generally connected to networks by a single line, owned by a single company. Governments seeking to foster competition can make that company sell access to its rivals. But the price is crucial. Too high, and consumers will see little competition. Too low, and the company itself will be unable to serve customers at a profit. In effect, if a company sells both iron and goods made from iron, the question is how much it should charge for the iron.
Mr. Tirole and his collaborators developed a model to assess whether companies in such markets were charging reasonable prices. Regulators have since applied their findings to a wide range of companies, particularly technology companies like Google that similarly depend on attracting both consumers and merchants to their platforms. The pricing model developed by Mr. Tirole and a now-deceased collaborator, Jean-Jacques Laffont, is the basis of current law in Europe, New Zealand, Australia and other countries. But not in the United States. Mr. Gans said the difference explained why consumers in those other countries generally enjoyed lower prices and better service.
“We owe Jean Tirole so much,” Joaquín Almunia, the European commissioner for competition, said in a statement on Monday. Mr. Almunia has pressed investigations of Google’s market power, and of bank pricing practices. “The alternative is what happens in the U.S. where Comcast doesn’t give access to its competitors so Time Warner has to decide whether to build over the top of Comcast or just to stay out of their markets,” Mr. Gans said. “Had there been access regulation, maybe Time Warner and Comcast would be competing more directly.”
Mr. Tirole also has been an advocate for increased financial regulation, including early work on the need to ensure that companies have access to funding during crises. The United States has taken Mr. Tirole’s work on antitrust enforcement more seriously. Beginning in the 1970s, many courts and regulators rejected the idea that companies could increase market power by buying their suppliers. A car company couldn’t squeeze consumers by buying a parts maker, the theory went, because it still would face the same competition from other carmakers.
“Banking is a very hard thing to regulate,” Mr. Tirole said in an interview broadcast on Monday during the awards announcement, in a comment that applies equally well to his views about the regulation of other markets too. Still, he applauded recent efforts to impose liquidity regulations on financial companies. Mr. Tirole’s work “successfully challenged” this view, the Nobel Prize committee said on Monday. He brought together evidence that such deals could have negative consequences and articulated a unifying theory that has proved influential.
Mr. Tirole said that regulators needed to pay attention to the links between regulated financial companies like banks and unregulated financial companies. “That is something we had forgotten or ignored before the crisis,” he said. “So now, when there is a major merger that involves important vertical relationships, the authorities take a more nuanced view,” said Mr. White, who served as chief economist of the antitrust division of the Justice Department in the early 1980s. “And we have Tirole in part to thank.”
Mr. Tirole also said that a more “global stance” was needed to regulate industries that increasingly operate on a global scale. He mentioned antitrust as an area of progress, and climate change regulation as an area of need. Mr. White said a recent example came in 2011, when the government conditioned Comcast’s acquisition of NBCUniversal on the terms of a deal that made NBCUniversal’s content available to Comcast’s rivals.
Mr. Tirole’s work also served as the basis for the European Union’s regulation of credit card interchange fees, and it has informed investigations by European regulators of the pricing policies of technology companies.
“We owe Jean Tirole so much,” Joaquín Almunia, the European Commission official responsible for competition, said in a statement Monday. Mr. Almunia has pressed investigations of Google’s market power and of bank pricing practices.
Mr. Tirole, however, has not always been an advocate of regulation. When Washington sued Visa and MasterCard in 1998 for preventing banks from issuing American Express cards, the companies cited Mr. Tirole’s work as showing that such membership rules were beneficial. More recently he has defended “patent pools,” where owners of related patents bundle their work.
Mr. Tirole received a doctorate in economics from the Massachusetts Institute of Technology in 1981, and he taught at M.I.T. for eight years before returning to France in the early 1990s. The economics school at Toulouse, which he helped found, is now a leading center for the study of regulation.
He was far ahead of most economists in advocating for increased financial regulation, including early work supporting easy access to funding for financial institutions during crises.
In an interview broadcast Monday during the awards announcement, Mr. Tirole applauded recent efforts to impose liquidity regulations on financial companies, but warned that “banking is a very hard thing to regulate.”
Mr. Tirole said regulators needed to pay attention to the linkages between regulated financial firms like banks and unregulated financial companies. “That is something we had forgotten or ignored before the crisis,” he said.
Mr. Tirole also said that a more “global stance” was needed to regulate industries that increasingly operate around the world, including actions to limit climate change.
The economics prize is the newest Nobel, created in 1969 to celebrate the 300th anniversary of the Bank of Sweden, the world’s first central bank. It is the first time since 1999 an American did not number among the winners.The economics prize is the newest Nobel, created in 1969 to celebrate the 300th anniversary of the Bank of Sweden, the world’s first central bank.
