Risk theory and management in actuarial science
3 lecture + 1 practical
Department of Discrete Mathematics
This course offers an introduction into the mathematical aspects of risk theory and quantitative risk managment. We will discuss basic concepts like the loss distribution, risk measurement, risk measures based on the loss distribution, e.g. value at risk or expected shortfall, as well as standard methods to compute market risk. Further we will give a basic introduction of extreme value theory and copulas and discuss applications of those in risk theory and insurance analytics. We will also introduce the credit risk management and discuss different credit risk models like structural models of default, threshold models, and the mixture model approach. Finally we will also tackle dynamic credit risk models.
After the successful completion of this course the students will be able to deal will quantitative risk models. They will be familiar with the mostly used models, their applicability, as well as their advantages and disadvantages in different situations.

The grade for the lecture will be the result of an oral examination.
The dates for the oral examination will be decided upon necessity and in agreement with the students.
The grade for the practical will be based on a continuous assessment in the practical units and a written examination on January 28, 2020.
The registration for the written examination should be done via TUGonline.
The success of the students in the practical will be measured in terms of points which can be collected during the term and at the written examination. The maximum amount of collectable points at the written examination is 12 with a minimum of 5 points to be achieved in order to be positively graded for the practical. The maximum number of collectable points during the practical units is 12. During the practical units students can collect points by preparing and presenting their solutions of the assignmemts; each correctly presented solution earns the presenter 3 points. A student has to present the solutions of at least four assignments in order to be positively graded for the practical. At the beginning of each practical unit the students should report which assignments they have prepared. Among all students who have prepared a certain assignment the instructor will select the candidate to present his/her solution on the board.
Notice: Students who claim to have prepared an assignment should be present at the practical unit in which the corresponfding assignment will be discussed. It the claim of having prepared some assignment cannot be satisfactoriry justified, then the point of all assignments of thecurrent unit (and in repeated cases also the points collected in previous units) will be cancelled!
Further, the instructor can credit 3 more points to any candidate for a beautiful solutions, an extraordinary presentation, etc.
The total number of collected points is given as follows
T= K + 12P/A +B/N+C where
|K||- points obtained at the written examination|
|P||- number of the prepared assignments|
|B||- points obtained for presentations on the board|
|A||- overall number of assignments|
|N||- number of presentations on the board|
|C||- credit points|
5 0 <= T <= 13
4 13 < T <= 17
3 17 < T <= 21
2 21 < T <=25
1 25< T
There will be a classical black-board lecture supported by slides the files of which will be uploaded here prior to each lecture.
Some lecture notes (old, in German, covering around 75% of the whole course material!) can be downloaded here.
will also be published hier, usually one week ahead of the corresponding practical unit.
