Question: The recent release of the movie A Beautiful Mind raises some questions regarding the efficacy of the work done by Nobel laureates John F. Nash, John C. Harsanyi, and Reinhard Selten. Their work involved the analysis of equilibria in the theory of non-cooperative games. Do you know of any written analysis of this work from an Objectivist perspective?
Answer: As such, Nash's contributions to non-cooperative game theory were a major breakthrough in the formal analysis of strategic interaction. Any interaction among individuals is fundamentally "non-cooperative," because each person's interests are distinct and each person decides as an individual. Even cooperation is "non-cooperative" in this sense. Nash's equilibrium concept, which is essentially that if one seeks to maximize one's benefit one should choose based on how one expects other parties to react, is valid in its field.
