1. Course Description syllabus

This is an introductory course in game theory, which will provide you with mathematical tools for analyzing strategically interdependent situations, i.e., the situation in which your optimal decision depends on what other people will do. In particular, we will study central solution concepts in game theory such as Nash equilibrium, subgame perfect equilibrium, and the Bayesian equilibrium. To illustrate the analytical value of these tools, we will cover a variety of applications, e.g., international relations, business competition, auctions, marriage market, and so forth. There is no prerequisite for this course, although some background on microeconomics and familiarity of probabilistic thinking would be helpful.

3. Textbooks

There is NO official textbook for the class. While lecture notes will be the main material for the class, the following textbooks are recommended for those who need supplementary readings.

Robert Gibbons, Game Theory for Applied Economists, 1992

Joel Watson, Strategy, 2nd edition, 2008

A useful text at roughly the same level as Gibbons, but contains variety of example, is:

Martin Osborne, An Introduction to Game Theory, 2004

For a quick guide to game theory, you may find the following useful.

Ken Binmore, Game Theory: A Very Short Introduction, 2007

Those of you interested in pursuing the subject further may consult with following advanced and authoritative sources.

Drew Fudenberg and Jean Tirole, Game Theory, 1991

Roger Myerson, Game Theory, 1991

Martin Osborne and Ariel Rubinstein, A Course in Game Theory, 1994

The following books contain many examples of game theory in action, both in business and in everyday life.

Barry Nalebuff and Avinash Dixit, The Art of Strategy, 2008

The old version with different title (Thinking Strategically, 1991) is also recommended.

Preston McAfee, Competitive Solutions, 2002

John McMillan, Games, Strategies, and Managers, 1992

The following textbooks provide a lively introduction to the game-theoretic perspectives on industrial organization and economic development, which may especially attract your interests.

Luis Cabral, Introduction to Industrial Organization, 2000

Bruce Wydick, Games in Economic Development, 2007

A chapter on game theory in microeconomics textbooks would be helpful. The following introductory and intermediate level books written by the same authors are recommended.

Walter Nicholson and Christopher Snyder [1], Intermediate Microeconomics and Its Application, 10th edition, 2005

Walter Nicholson and Christopher Snyder [2], Microeconomic Theory: Basic Principles and Extensions, 10th edition, 2007
