In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood, a rigorous analysis of investment incentives is still missing. Existing...

Public goods provision often involves groups of contributors repeatedly interacting with administrators who can extract rents from the pool of contributions. We suggest a novel identification approach that exploits the sequential ordering of decisions in a panel vector autoregressive model to...

In this study, we investigate how and why people discriminate among different groups, including their own groups and multiple out-groups. In a laboratory experiment, we use dictator games for five groups to compare actual transfers to in-group and out-group agents with the respective beliefs...

We conduct an experimental study among European citizens regarding cross-cultural perceptions related to trust in two dimensions: volunteerism and honesty. We use representative samples from five major economies of the Euro area: France, Germany, Italy, the Netherlands, and Spain. We find that...

We conduct multi-person one-shot ultimatum games that reflect important aspects of collective bargaining. In all treatments a proposer has to divide a pie among herself and six recipients that are divided into two groups of three. The proposer cannot discriminate among, but across group members....

This paper explores whether tax planning by households is consistent with a minimization of the family tax burden or whether and to what extent altruism and concerns about the tax loss of individual household members matter. To this end, we take advantage of a specific feature of the German tax...

We conduct multi-person one-shot ultimatum games that reflect important aspects of collective bargaining. In all treatments a proposer has to divide a pie among herself and two groups of three recipients each. She cannot discriminate within, but across groups. A committee with representatives...

Empirische Studien weisen darauf hin, dass der Gender Wage Gap – die geschlechtsspezifische Lohnlücke – im Tarifbereich geringer als im nichttarifgebundenen Bereich der Wirtschaft ausfällt. Dennoch ist es eine weitgehend offene Frage, wie sich die Strukturen und der Ablauf von...

Der Beitrag untersucht mit LIAB-Daten für die Jahre 2000 bis 2010, wie sich der Gender Pay Gap bei Vollzeitbeschäftigten im Zeitablauf entwickelt hat. Dabei wird zwischen dem nicht-tarifgebundenen Bereich der Wirtschaft und dem Bereich mit Flächentarifverträgen differenziert. Die Befunde...

This paper studies public goods provision in an experiment in which contributors repeatedly interact with rent-extracting administrators. Our main result is that the presence of an administrator reduces contributions but only because rent extraction lowers the MPCR. Analysing the dynamic...
