This is a course in game theory and its application to management, including business strategy. It offers an introduction to a selection of the methods and results of modern game theory. Emphasis is placed on the practical applications of these tools. The audience for this course is anyone interested in the fundamental principles that are used in the disciplined and therefore necessarily abstract analysis of general strategic situations that cookie-cutter solutions and popular heuristics cannot cover. In particular, those interested in general management or consulting may enjoy the course.
