Evolution, Rationality and Equilibrium in Games Jörgen W. Weibull


Evolutionary game theory studies the robustness of strategy profiles and sets of strategy profiles with respect to evolutionary forces in games played repeatedly in large populations of boundedly rational agents. The approach is macro oriented in the sense of focusing on the strategy distribution in the interacting population(s). Some main features of this approach are here outlined, and connections with learning models and standard notions of game-theoretic rationality and equilibrium are discussed. Some desiderata and results for robust long-run predictions are considered.

This book explores the complex and ever-changing relationship between the European Union and its member states. The recent surge in tension in this relationship has been prompted by the actions of some member state governments as they question fundamental EU values and principles and refuse to implement common decisions seemingly on the basis of narrowly defined national interests.
