Zusammenfassung der Projektergebnisse

This research project contributed to the improved estimation of downsided financial risk measures. The improvements include the use of high frequency data, the optimal combination of alternative risk measures and by joint estimation and testing of of the risk measures accounting for elicitability. In several empirical applications it was shown, that the conventional approaches, which still are in use by financial institutions are far from being optimal. Financial risk are not only inherent to financial markets, they are also the result of the use of mediocre tools to measure them. The project results point out that proper risk measurement in the future should make heavy use of the plethora of financial data and econometric models by machine learning techniques and appropriate sampling techniques.
