Joseph Stiglitz

The Nobel Memorial Prize in Economics in 2001 "for laying the foundations for the theory of markets with asymmetric information" with George A. Akerlof and A. Michael Spence.

Before the advent of models of imperfect and asymmetric information, the traditional neoclassical economics literature had assumed that markets are efficient except for some limited and well defined market failures. More recent work by Stiglitz and others reversed that presumption, to assert that it is only under exceptional circumstances that markets are efficient.

Problems of information are central to understanding not only market economics but also political economy.
