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...

In general, consumer preferences depend on the context of a decision situation. This paper highlights the context-dependence of substitution behavior in out-of-stock (OOS) situations and provides evidence for the relevance of promotion as essential driver of customers' OOS reactions. We...

Out-of-Stock (OOS) is a prevalent problem customers face at the POS. In this paper, we demonstrate both theoretically and empirically how OOS-induced substitution patterns can be explained and predicted by means of context and phantom theory. We further analyze the relevance of promotions, for...

This paper studies the link between group-specific consumption growth and volatility within a framework of heterogeneous agents, under the assumption of a consumption externality. Household preferences are related to the volatility through asset holding decisions: volatility decreases with...

The mandatory adoption of IFRS by many countries worldwide fuels the expectation that financial accounting information might become more comparable across countries. This expectation is opposed to an alternative view that stresses the importance of incentives in shaping accounting information....

This paper examines pecuniary aspects of work during unusual hours based on the German Time Use Data for 2001/02. The findings show positive wage premia of 9 - 10 percent for shift workers and men who work during unusual hours. There is some evidence of negative selection which suggests that men...

The analysis of return series from financial markets is often based on the Peaks-over-threshold (POT) model. This model assumes independent and identically distributed observations and therefore a Poisson process is used to characterize the occurrence of extreme events. However, stylized facts...

This paper analyzes determinants for regional differences in German unemployment rates. We specify a spatial panel model to avoid biased and inefficient estimates due to spatial dependence. Additionally, we control for temporal dynamics in the data. Our study covers the whole of Germany as well...
