David Pearce is a prominent game theorist and economist, currently a professor at New York University. He is best known for his foundational contributions to the theory of games, particularly in the areas of equilibrium concepts, refinements, and repeated games. Pearce’s work has significantly influenced the development of modern game theory, especially through his exploration of how rational players form expectations and how these expectations influence their strategic decisions. Among his key contributions are the concepts of “rationalizability” and the recursive structures of dynamic game equilibria, which have become fundamental tools in the analysis of strategic behavior in economics and other social sciences.
