This paper investigates the impact of the largest rail strikes in German history on intercity buses - a then newly liberalised market. Using unique booking data of bus services, we exploit variation in rail service cancellations across routes to show that the disruption in rail transport...

This paper investigates the impact of the largest rail strikes in German history on intercity buses – a then newly liberalised market. Using unique booking data of bus services, we exploit variation in rail service cancellations across routes to show that the disruption in rail transport...

In this paper, we present an innovative electricity spot price model, wherein the prices explicitly depend on the realized wind power production. The proposed arithmetic multi-factor approach captures numerous stylized facts of empirical spot price behavior like seasonal variations,...

This paper investigates a corporation's risk management response to highly dynamic risks. Using a unique data set on the German terrorist insurance market, the paper tests whether corporate risk managers have a clear understanding of the probability distribution of highly dynamic risks or if...

Current research on (managerial) turnover mainly focuses on performance changes and is ambiguous with respect to the results. Yet, the literature agrees that short-term performance changes are induced by opposing effects. Specifically, a turnover leads to an information loss that might influence...

Es wird ein liberaler Ansatz zum Umgang mit der aktuellen Corona-Pandemie vorgestellt, der mehr auf individuellen Entscheidungen und Eigenverantwortung setzt als auf staatliche Vorgaben und Zwang, die weder besonders effektiv noch effizient sind. Die Anwendung dieses Ansatzes wird für...

Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

In this article we demonstrate how challenging greenhouse gas reduction targets of up to 95% until 2050 can be achieved in the German electricity sector.1 In the analysis, we focus on the main requirements to reach such challenging targets. To account for interdependencies between the...
