My research is concerned with learning in games and its application to the diffusion of innovations, the evolution of social norms and institutions, and the design of decentralized systems of communication and control. I’m also interested in applications of game theory to finance. I am a past-president of the Game Theory Society, a fellow of the American Academy of Arts and Sciences,  the British Academy, the Society for the Advancement of Economic Theory, and the Econometric Society. Currently I am James Meade Professor of Economics, Emeritus at the University of Oxford and Centennial Professor of Mathematics at the London School of Economics.
