This paper provides implied measures of higher-order dependencies between assets. The measures exploit only forward-looking information from the options market and can be used to construct an implied estimator of the covariance, co-skewness, and co-kurtosis matrices of asset returns. We...

This paper provides implied measures of higher-order dependencies between assets. These measures exploit only forward-looking information from the options market and can be used to construct an implied estimator of the full covariance, co-skewness, and co-kurtosis matrices of asset returns. In...

We introduce an ensemble learning method based on Gaussian Process Regression (GPR) for predicting conditional expected stock returns given stock-level and macro-economic information. Our ensemble learning approach significantly reduces the computational complexity inherent in GPR inference and...

Modellierung der Abhängigkeiten zwischen Ausfall, Verlustrate und Forderungshöhe bei Ausfall mit Faktoren und Copulae -- Multivariate Erweiterung des Heckman-Schätzers, um der Stichprobenselektion seitens der Verlustrate und der Forderungshöhe gerecht zu werden -- Empirische Befunde zur...

Markowitz portfolio selection is a cornerstone in finance, both in academia and in the industry. Most academic studies either ignore transaction costs or account for them in a way that is both unrealistic and suboptimal by (i) assuming transaction costs to be constant across stocks and (ii)...
