Book excerpt: Behavioural game theory is the most important recent development of standard game theory, and its applications regard several fields of research, ranging from economic theory to sociology and political science. Behavioural game theory aims to provide a behavioural and psychological approach to game theory modelling, in order to identify more robust equilibrium outcomes and more realistic behavioural assumptions. This book explores the key topics in detail, covering issues such as players' heterogeneity, social preferences, reciprocity, learning and information, and punishment in public good games. It provides a state-of-the-art analysis of the progress and methodology of behavioural game theory, as well as exploring the interdisciplinary aspects of the subject, and is an extremely valuable resource for academics and scholars with an interest in the area.
