Over the 2000s, many federal states in Germany shortened the duration of secondary school by one year while keeping the curriculum unchanged. Exploiting quasi-experimental variation due to the staggered introduction of this reform allows me to identify the causal effect of increased learning...

This paper analyses the effects of minimum wages on competition in the German roofing sector. The case is particularly interesting since this sector is faced with a uniform minimum wage despite significant regional disparities in productivity and wages. As a control industry we take the plumbing...

We explore the role of social capital in the spread of the recent Covid-19 pan­demic in independent analyses for Austria, Germany, Italy, the Netherlands, Swe­den, Switzerland and the UK. We exploit within-country variation in social capital and Covid-19 cases to show that...

Foreign-owned subsidiaries make significant contributions to national Research and Development (R&D) in many host countries. Policymakers often support subsidiaries through R&D grants and R&D tax credits. A key objective of this funding is to leverage R&D-driven firm performance benefits for the...

To adequately design and implement effective environmental policies, it is paramount for policymakers to understand preferences for regulatory instruments as well as their individual level determinants. In this study, I experimentally investigate the demand for three environmental policies,...

In a field experiment with 341 participants, we study whether social comparisons, either in isolation or in combination with a climate-related moral appeal, can change the use of public and car-related transportation. We do so in the context of a mobility budget offered to employees of a large...

The R&D policy instrument mix concept has become increasingly important for understanding how public R&D support drives firm-level R&D. To-date, empirical studies have conceptualised the instrument mix as a static unit, whereby firms receive multiple policy instruments at one point in time....

We test whether and, if so, how incentives to promote pro-social behavior affect the extent to which it spills over to subsequent charitable giving. To do so, we conduct a two-period artefactual field experiment to study repeated donation decisions of more than 700 participants. We vary how...

We study the effect of direct democracy on local taxation. Our setting is the German federal state of Bavaria, where in 1995 a state-wide referendum introduced the possibility to initiate direct democratic legislation into the local government code. Relying on a sample of all Bavarian...
