We investigate how the experience of extreme events, such as the COVID-19 market crash, influence risk-taking behavior. To isolate changes in risk taking from other factors, we ran controlled experiments with finance professionals in December 2019 and March 2020. We observe that their...

In this paper we investigate how volatility shocks influence investors' perceptions about a stock's risk, its future development, and investors' investment propensity. We ran artefactual field experiments with two participant pools (finance professionals and students) that had to take investment...

While headline news frequently report cases of large-scale fraud, corruption, and other immoral behavior, laboratory experiments often show prosocial behavior in strategic games. To reconcile and explain these seemingly conflicting observations, Al'os-Ferrer et al. (2022) introduced the Big...

We conducted a randomized controlled trial in a lab and natural setting to investigate whether exposure to nature leads people to behave more pro-environmentally. We further investigated whether attention restoration mediates this effect. Participants were randomly assigned to one of four...

In a pre-registered laboratory asset market study, we investigate dynamics of asset markets with zero (or close to zero) fundamental values. We introduce the "greater fool asset market game" with a zero-value token, whose price doubles in each period. We design several treatments, which differ...

While politically attractive in order to generate tax revenues, the effects of a financial transaction tax (FTT) are scientifically disputed, not the least because seemingly small details of its implementation may matter a lot. In this paper, we provide experimental evidence on the different...

In an experiment with 739 subjects we study whether and how different interventions might have an influence on the degree of moral behavior when subjects make decisions that can generate negative externalities on uninvolved parties. Particularly, subjects can either take money for themselves or...
