STOCKHOLM - US economists Alvin Roth and Lloyd Shapley won the 2012 Nobel prize for economics on Monday for research on how to match different economic agents such as students for schools or even organ donors with patients.
The Royal Swedish Academy of Sciences, which made the award, said the 8 million crown ($1.2 million) prize recognized "the theory of stable allocations and the practice of market design."
The award citation said Shapley had used game theory to study and compare various matching methods and how to make sure the matches were acceptable to all counterparts, including the creation of a special algorithm.
Roth followed up on Shapley's results in a series of empirical studies and helped redesign existing institutions so that new doctors could be matched with hospitals, students with schools or patients with organ donors.
"This year's prize is awarded for an outstanding example of economic engineering," the committee added.
