Prize motivation: "for their analyses of markets with asymmetric information."
Contribution: Showed how the able agents may improve the market outcome by taking costly action to signal information to poorly informed recipients. An important example is education as a signal of high individual productivity in the labor market. It is not necessary for education to have intrinsic value. Costly investment in education as such signals high ability.
Prize share: 1/3
