This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt taking. We show suggestive evidence for a link between overconfidence and borrowing behavior in a representative survey of German households (German Socio-Economic Panel–Innovation Sample [GSOEP-IS]). This motivates a laboratory experiment to study causality behind these effects. In two experiments, ...

This study explores how gender and age interact in shaping beliefs about fair pay through a factorial survey experiment conducted with German employees. Respondents evaluated hypothetical worker descriptions varying in age, gender, and earnings. While no gender gap in fair earnings was found for the youngest hypothetical workers, a significant gap favoring men emerged with increasing age. This suggests ...

We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany dur¬ing 2015-2022. We account for confounding time trends and interacting EU-level CO2 standards using neighboring countries as a control group. We find that 40% of BEV and 25% of PHEV registrations were subsidy-induced. The program ...

How does basic income (a regular, unconditional, guaranteed cash transfer) impact labor supply? We show that in search models of the labor market with income effects, this impact is theoretically ambiguous: Employment and job durations might increase or decrease, match surplus might be shifted to workers or employers, and worker surplus might be reallocated between wages and job amenities. We thus ...

We provide novel evidence about the incentive and welfare effects of an increase in the generosity of disability benefits. Importantly, a unique policy variation in Germany allows us to isolate the income effect of a change in benefit generosity. We leverage this quasi-experimental policy variation using an RD design to estimate the effect of increasing disability benefits on employment, earnings, ...
