Alvin Roth and Lloyd Shapley win the Nobel prize for economics for their work on how markets without a price mechanism, such as the matching of students to schools and organ donors to recipients, can be made to work more effectively. Roth's empirical studies and applications built on Shapley's theoretical game-theory work on cooperative games a generation earlier. Roth has also worked on matching in repugnant markets, those in activities regarded by a society as taboo.
