## Game Theory (2017)

#### FIN-620

#### Lecturer(s) :

Dimopoulos Theodosios#### Language:

English

#### Summary

Game theory deals with multiperson strategic decision making. Major fields of Economics, such as Microeconomics, Corporate Finance, Market Microstructure, Monetary Economics, Industrial Organization, International Trade Theory all build on game theoretic foundations.#### Content

The aim of the course is to provide an introduction to non-cooperative game theory for PhD and advanced graduate students. Topics are selected on the basis of their relevance for active areas of research in Finance. They contain an analysis of non-cooperative static and dynamic games. Emphasis is placed on the role of information in determining game outcomes, in designing incentives and in renegotiating existing incentive schemes.

#### Learning Outcomes

By the end of the course, the student must be able to:- Define alternative notions of Equilibria
- Derive game equilibria and select among them
- Design games and incentive schemes to induce desired targets

#### Assessment methods

- The course is accompanied by 8 problem sets. They are excellent preparation for the exam, but do not count as part of the final grade.
- The final grade for the course is:

**Grade=100%*Final Exam**
