Match-making US scientists earn Nobel prize

Life-saving kidney exchange programmes and ways for schools to select students are just two practical applications of the market-matching theories for which US economists Alvin Roth and Lloyd Shapley won the Nobel prize for economics yesterday.

Pairing up employers with job seekers are other examples of how Roth, 60, and Shapley, 89, have separately applied game theory to daily life.

The Royal Swedish Academy of Sciences, which awards the 8m crown (€931,400m) prize, called their work an outstanding example of economic engineering.
