In a fundraising field experiment we show that individuals are not only conditionally cooperative, but that they are also more prone to donate to a homeless individual when the previous donor has a higher social status. We trailed a homeless person asking for donations within Cologne's metro...

We study the effects of a label awarded to universities for excellence in research on students' perception of educational quality and enrolment in subsequent admission terms. Using a representative student survey we find that students evaluate the teaching and supervision quality of their...

We propose a new model that can capture the typical features of multivariate extreme events observed in financial time series, namely clustering behavior in magnitudes and arrival times of multivariate extreme events, and time-varying dependence. The model is developed in the framework of the...

This paper tests whether staying ignorant about the negative consequences of one's own actions affects agents' performance in a real effort experiment. We conducted treatments in which subjects' effort either increased only one's own payoff or also increased the donation to a bad charity....

How to hire voluntary helpers? We shed new light on this question by reporting a field experiment in which we invited 2,859 students to help at the 'ESA Europe 2012' conference. Invitation emails varied non-monetary and monetary incentives to convince subjects to offer help. Students could apply...

We examine the extent to which labor supply elasticities with respect to tax rates depend on access to evasion opportunities. It is observed that some types of workers have the opportunity to hide their income while others do not have such opportunities, e.g. due to being subject to...

This paper studies the behavioral effects of intra-firm trainings on absence behavior and turnover probability. We argue that participation in firm-sponsored trainings might lead to behavioral responses among employees. When firms pay for general trainings, employees may perceive this as a gift...

We provide an extensive overview of the determinants of the fixed and variable compensation schemes in the German and Swiss financial services industry. We find that the financial crisis had a deep impact on the proportion of variable pay to fixed salary; this impact was caused by large...

As the link between tax compliance and tax morale is found to be robust, finding the determinants of tax morale can help to understand and fight tax evasion. In this paper we analyze the effect of progressive taxation on tax morale in a cross-country approach - which has not been investigated...

We introduce a new discounted cash flow model which adopts the diversification effect of multi-business firms. We face two challenges: One is examining how different diversification extents can affect the firm value due to risk reduction, and the other is modeling segment-specific cash flows and...
