This landmark volume brings together the key articles on Game Theory published over the past half century and supplements them with section introductions and pedagogical features to help graduate students and advanced undergraduate students explore the key tenets of the discipline. Starting with John Nash, many of the articles are classics in the field, but the book also contains a large number of newer cutting-edge articles that are likely to form the basis of the discipline in the future. The articles are presented in nine sections. Each section opens with an introductory article that places the articles within in context and guides the reader in their further reading. Key topics explored within this book include: Repeated Games Incomplete Information Learning and Evolutionary Game Theory Political Economy and Behavioral Economics Among the authors whose work is produced are Ariel Rubinstein, Robert Aumann, Roger Myseron, Drew Fudenberg and Matthew Rabin. The Reader is edited by Muhamet Yildiz of the Massachusetts Institute of Technology.
