This paper quantifies liquidity and credit premia in German and French government bond yields. For this purpose, we estimate term structures of government-guaranteed agency bonds and exploit the fact that any difference in their yields vis-`a-vis government bonds can be attributed to differences...

Student’s t-distributions are widely used in financial studies as heavy-tailed alternatives to normal distributions. As these distributions are not closed under convolution, there exist no Lévy processes with Student’s t-marginals at all points in time. In this article we show that a...

Levy copulas are the most general concept to capture jump dependence in multivariate Levy processes. They translate the intuition and many features of the copula concept into a time series setting. A challenge faced by both, distributional and Levy copulas, is to find flexible but still...

Many nonlinear extensions of the Kalman filter, e.g., the extended and the unscented Kalman filter, reduce the state densities to Gaussian densities. This approximation gives sufficient results in many cases. However, this filters only estimate states that are correlated with the observation....

Measures of association are suggested between two random vectors. The measures are copula-based and therefore invariant with respect to the univariate marginal distributions. The measures are able to capture positive as well as negative association. In case the random vectors are just random...

This paper quantifies the degree of market power in the German wholesale electricity market. A fundamental model is used to derive competitive marginal cost estimators which are compared with observed electricity prices. Marginal costs are calculated focusing on market fundamentals such as plant...

This paper analyzes the effects of start-up costs of different technologies in providing electricity power. We explicitly solve a simplified linear formulation of the dispatch problem. Transforming this primal problem, we show that dominated technologies should be used only in the case of...

Die öffentliche Debatte über die Entwicklung der deutschen Strompreise im Anschluß an die Liberalisierung der Energiemärkte 1998 wirft die Frage nach einem Scheitern der Umstrukturierung dieser Märkte auf. Die Analyse der Entwicklung der Strompreise für Haushaltskunden von 1998 bis 2005...

Welche Chancen und Risiken ergeben sich aus der Schiefergasförderung in Europa und speziell in Deutschland? Nach Ansicht von Felix Müsgens, Brandenburgische Technische Universität Cottbus-Senftenberg, und Andreas Seeliger, Duale Hochschule Baden-Württemberg Mosbach, sollte die skeptische...
