US scholars Alvin Roth and Lloyd Shapley won the Nobel Economics Prize for their work on how to best match supply and demand that has potential applications in organ donation, education and on the Internet. The two were honoured for "the theory of stable allocations and the practice of market design," the Royal Swedish Academy of Sciences said on Monday. The work can be used to help match donors of human organs with patients in need of a transplant, or students with universities, or Internet search engines that auction space for advertisers. Roth, 60, is a professor at Harvard Business School in Boston, Massachusetts, while Shapley, 89, is a professor emeritus at the University of California. Roth told public broadcaster Swedish Television he was surprised to win the award. "No it wasn't expected. But it is certainly expected that Lloyd Shapley won the prize ... I'm glad to share it with him," he said. Roth said he was happy that the prize would "shine a very bright spotlight on the work" he and Shapley had done in market design, which Roth described as "a newish area of economics." The professor then quipped: "When I go to class this morning my students will pay more attention." Shapley's age was mentioned in economic circles on Monday as a factor that may have been in his favour this year, even though his field of research isn't one that hits the headlines very often. In choosing market design theory for this year's prize, the Royal Swedish Academy of Sciences avoided wading into a heated macroeconomic debate over fiscal policy, austerity measures and stimulus packages. "We neither try to pick topics that are the subject of much debate, nor do we try to avoid them," Per Krusell, chairman of this year's Economic Sciences Prize Committee, told AFP. "This year's prize just happens to ... not have any connection whatsoever, that I can see, to the financial crisis." Roth and Shapley worked independently of each other but "the success of their research is due to the combination of Shapley's theoretical results with Roth's insights into their practical value," the committee said. Resources are often allocated through a pricing mechanism: high oil prices give consumers an incentive to conserve energy, and high wages attract workers to a particular profession. But in many markets, pricing is not enough to match different agents. Money is not the only factor that decides which hospital a doctor wants to work in, or which university would be best for a prospective student. Central to Shapley's and Roth's work is the notion of stability, which results for example in the allocation of resources such that individuals do not then perceive any gains from further swaps, or trade. In a 1962 paper, Shapley applied the idea of stability to that of marriage. How could individuals in a group of people be paired up when they all had different views on who would be their best match? The best match-making was achieved by using what is now known as the Gale-Shapley "deferred acceptance" algorithm, a set of rules which aim to achieve a stable solution. This year's award confirms the US dominance in the Nobel Economics Prize. Of the 20 laureates who've won in the past 10 years, 17 are Americans, including two Israeli-Americans. Roth and Shapley will receive the prize, consisting of a Nobel diploma, a gold medal and 8.0 million Swedish kronor ($1.2 million, 921,000 euros), at a ceremony in Stockholm on December 10, the anniversary of Swedish industrialist and prize creator Alfred Nobel's death. Last year, the prize went to US researchers Thomas Sargent and Christopher Sims for research on the causal relationship between economic policy and different macroeconomic variables, such as gross domestic product, inflation, employment and investments. Monday's economics prize wraps up the 2012 Nobel season. Last week, the Nobel Peace Prize, perhaps the most-watched of the Nobels, was awarded to the European Union for bringing more than half a century of peace to a continent ripped apart by two world wars, a choice met by both praise and ridicule. The awarding of the Nobel Literature Prize to Chinese writer Mo Yan also sparked controversy, with Chinese dissidents accusing him of being a communist stooge.
