Summary

In recent times game theory has been applied with success to a range of issues in economics, social science and business. This new core textbook is a thorough and challenging introduction to game theory and its applications in the various fields of economics and related disciplines. It presents a comprehensive coverage of standard as well as new developments in the field, including cooperative games, evolutionary game theory and experimental games. Game Theory and Economics is an ideal course companion for students studying game theory at either undergraduate or postgraduate level. Book jacket.
