After failing to fully recover from the last financial crisis, the pandemic poses major new challenges for banks. However, this time, banks are not the problem, but part of the solution. By providing credit to the economy, banks play a crucial role in fighting the pandemic by ensuring the transmission of fiscal and monetary stimulus to the economy. Nevertheless, banks are not among the winners of...

Following a landmark ruling by the Constitutional Court in 2005, more than half of Germany's universities started charging tuition fees, which also applied to incumbent students. We exploit this unusual lack of grandfathering together with register data covering the universe of students to show that tuition fees increased degree completion among incumbent students. Investigating mechanisms, we do not ...

Previous work has shown that preferences are not always stable across time, but surprisingly little is known about the reasons for this instability. I examine whether variation in people’s emotions over time predicts changes in risk attitudes. Using a large panel data set, I identify happiness, anger, and fear as significant correlates of within-person changes in risk attitudes. Robustness checks indicate ...

DIW Discussion Papers 1950 / 2021
This paper examines the effect of reduced self-control on impulsive borrowing in a laboratory experiment. We manipulate self-control using an ego depletion task and show that it is effective. Following the ego depletion task, participants can anonymously buy hot drinks on credit. We find no significant average effects, but find that treated individuals that have low financial literacy are more likely ...

With regard to the European Union’s climate targets, it is likely that the demand for green bonds—bonds that specifically support sustainable projects— will continue to increase in the future. The European Central Bank (ECB) is buying green bonds as well and is planning to reorient its strategy towards more sustainability. ...

The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. However, ...

Refereed essays Web of Science
In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroscedasticity is occasionally allowed for in inference, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change in their variances. We develop a test for this implicit assumption and present evidence that the assumption ...
