Market risk management is one of the key factors to success in managing financial institutions. Underestimated risk can have desastrous consequences for individual companies and even whole economies, not least as could be seen during the recent crises. Overestimated risk, on the other side, may...

The globalisation on financial markets and the development of financial derivatives has increased not only chances but also potential risk within the banking industry. Especially market risk has gained major significance since market price variation of interest rates, stocks or exchange rates...

A non-stationary regression model for financial returns is examined theoretically in this paper. Volatility dynamics are modelled both exogenously and deterministic, captured by a nonparametric curve estimation on equidistant centered returns. We prove consistency and asymptotic normality of a...

Summary This paper provides new estimates of a time-varying NAIRU for Germany taking account of the structural break caused by German unification using two alternative estimators, the Kalman- Filter and the partially linear model. Estimating a standard Phillips curve, the sum of coefficients...

Eine große Herausforderung der multivariablen Analyse mit bilanziellen Kennzahlen besteht in der Identifikation derjenigen Kennzahlen, die zur besten Modellperformance führen und dabei möglichst leicht interpretierbar und intuitiv bleiben. Die Menge der in Frage kommenden Kennzahlen ist in...

Abstract German (English abstract is added below) Arbeitslosigkeit gilt als eines der schwerwiegendsten gesellschaftlichen Probleme unserer Zeit. Doch welche Gründe liegen, trotz der über die Jahre eingeleiteten Maßnahmen zur Bekämpfung der Arbeitslosigkeit, für die anhaltende...

Die gegenwärtigen Kontroversen zu den Auswirkungen eines Energieembargos gegen Russland, ausgelöst durch Russlands Krieg gegen die Ukraine, haben den Fokus auf die Verringerung der Abhängigkeit von fossilen Energieträgern und eine Neuordnung der Energieversorgung gelegt....
