This course presents, at a medium level, the concepts and tools for the analysis of situations where decision problems of various actors are interdependent, and some actors possibly possess more information than others. Typical issues involve predictions of outcomes ("equilibria"), credibility of threats, the analysis of actors' beliefs over time, and the strategic use of information. Many applications are discussed: Competition or collusion in markets, tragedy of the commons, football penalties, chess, threats and credible deterrence, learning and spamming, how to design or participate in auctions, and more.
