Kurzbeschreibung The aim of the course is to present an overview of risk measures available in the academic literature or currently used in practice emphasizing their properties and drawbacks. Students will then be familiar with VaR, Expected shortfall, coherent and convex risk measures and the recent expectiles. The course will also discuss practical issues arising from estimating and backtesting risk measures.
Lernziel Risk measures are important tools for managing and quantifying financial and insurance risks. The aim of the course is to present an overview of different kind of risk measures available in the academic literature or currently used in practice emphasizing their properties and drawbacks. Students will then be familiar with VaR, Expected shortfall, coherent and convex risk measures but also with the more recent expectiles. The last part of the course will discuss practical issues arising from estimating and backtesting risk measures.
Inhalt -Introduction to monetary risk measures and their use in finance and actuarial science;
-VaR: definition, examples and drawbacks;
-Expected shortfall and distorted risk measures:coherency and comotonicity;
-Robust representation of coherent and convex risk measures;
-Shortfall risk measures: the entropic risk measure and expectiles;
-Law-invariant risk measures and their definition on probability distribution spaces;
-Forecasting and backtesting of a risk measure.
