Two U.S. economists win the Nobel Prize in economics for their match-making science

Two Americans were awarded the Nobel economics prize on Monday for studies on the match-making taking place when doctors are coupled up with hospitals, students with schools and human organs with transplant recipients.

The work of Alvin Roth and Lloyd Shapley has sparked a 'flourishing field of research' and helped improve the performance of many markets, the Royal Swedish Academy of Sciences said.

Roth, 60, is a professor at Harvard University in Boston. Shapley, 89, is a professor emeritus at University of California Los Angeles.
