Nobel Prize for “Market Design”

This year’s Nobel-ish prize in economics goes to Alvin Roth and Lloyd Shapley for research on “matching methods” and the resulting application to “market design.” Briefly, this work deals with allocating resources in the absence of money and prices. Shapley applied noncooperative game theory to study the properties of different matching rules, and Roth studied various allocation rules to encourage “efficient” matching of actors or traders without using prices.
