Mean field game theory

Mean field game theory is the study of strategic decision making in very large populations of small interacting individuals. This class of problems was considered in the economics literature by Jovanovic and Rosenthal, in the engineering literature by Peter E. Caines and his co-workers and independently and around the same time by Jean-Michel Lasry and Pierre-Louis Lions.

Use of the term 'mean field' is inspired by mean field theory in physics which considers the behaviour of systems of large numbers of particles where individual particles have negligible impact upon the system.
