Reinhard Selten, 1994 Nobel prize and founding father of experimental economics, predicted that individuals wouldn’t play the conventional Nash Equilibrium in the Ultimatum Game, better known as a take-it-or-leave-it offer.

Tension between the United States and North Korea has reached a stage where missile strikes have become an alarming possibility. If tensions escalate further to a state where military action looks almost certain, game theory could offer us insight into finding the best strategy to tackle the problem. Firstly though, what does Kim Jong Un hope to achieve by possessing a nuclear arsenal? It is … Continue reading The US v. North Korea: The role of game theory
