Observing prices of European put and call options, we calibrate exponential Lévy models nonparametrically. We discuss the implementation of the spectral estimation procedures for Lévy models of finite jump activity as well as for self-decomposable Lévy models and improve these methods....

What is the impact of a local negative demand shock on local labor markets? We exploit the unique natural experiment provided by the drawdown of U.S. military forces in West Germany after the end of the Cold War to investigate this question. We find persistent negative effects of the reduction...

By analyzing occupational task profiles, an occupational change can be split up into two components: (1) transferability of task portfolios between occupations and (2) change in the value of the occupation-employee match. Extending the task-based approach of Gathmann and Schönberg (2009) by...

This paper uses the task-based view of technological change to study employment and wage polarization at the level of local labor markets in Germany between 1979 and 2007. In order to directly relate technological change to subsequent employment trends, we exploit variation in the regional task...

This paper employs a new and comprehensive data set to investigate short-term herding behavior of institutional investors. Using data of all transactions made by financial institutions in the German stock market, we show that herding behavior occurs on a daily basis. However, in contrast to...

We exploit the natural experiment of the 2005 income tax reform in Germany to study the effects of tax incentives on consumer behavior in life insurance markets. Our empirical analysis of sociodemographic, economic, and psychological household characteristics elicited in the German SAVE study...

A substantial number of empirical studies on the linear relationship between executive compensation and firm performance for European firms suggest that the pay-performance sensitivity is not significantly positive. We argue that a nonlinear structure fits the data better, because compensation...

When we started the development of our CD to support the teaching of our basic statistic courses our work was twofold: we had to develop the content and the necessary software ourselves. Maintaining our software development in a university environment turned out to be especially difficult since...

Good corporate reputation is seen as one of the most valuable assets. It is believed to cause a multitude of favorable impacts within different stakeholder groups. As a consequence, a multitude of studies analyzed the relationship between corporate reputation and financial performance. However,...

Quotas for special groups of students often apply in school or university admission procedures. This paper studies the performance of two mechanisms to implement such quotas in a lab experiment. The first mechanism is a simplified version of the mechanism currently employed by the German central...
