Basic background in mathematics and microeconomics.
The course will present the basic theory of normal-form games and extensive-form games necessary to address the economic applications listed in the contents below.
The goal of the course is to introduce the student to the consequences of the fact that economic agents often behave strategically, taking into account the interdependency of other agents’ decisions on their own; the course will also study the outcome of economic interactions in competitive markets. To that end the student will be provided with the tools and methods of game theory necessary to address the issue.
