In credence goods markets, experts have better information about the appropriate quality of treatment than their customers. Experts may exploit their informational advantage by defrauding customers.

According to Chen’s (2013) linguistic-savings hypothesis, languages which grammatically separate the future and the present (like English or Italian) induce less future-oriented behavior than languages in which speakers can refer to the future by using present tense (like German). We...

This study investigates the relationship between economic preferences and COVID-19 vaccination readiness using two representative samples of the German population (N 5,000). We elicited altruism, patience, risk-taking and trust using validated survey questions. We find robust, positive...

Social norms affect a wide range of behaviors in society. We conducted a representative experiment to study how beliefs about the existing social norm regarding COVID-19 vaccination affect vaccination readiness. Beliefs about the norm are on average downward biased, and widely dispersed....

We present representative evidence of discrimination against migrants through an incentivized choice experiment with over 2,000 participants. Decision makers allocate a fixed endowment between two receivers. To measure discrimination, we randomly vary receivers' migration background and other...

Peoples’ willingness to vaccinate is critical to combating the COVID-19 pandemic. We devise a representative experiment to study how the design of the vaccine approval procedure affects public attitudes towards vaccination. Compared to an Emergency Use Authorization, choosing the more thorough...

We present direct evidence on the link between children’s patience and educational-track choices years later. Combining an incentivized patience measure of 493 primary-school children with their high-school track choices taken at least three years later at the end of middle school, we find...

Large, macroeconomic shocks in the past have been shown to influence economic decisions in the present. We study in an experiment with 743 subjects whether small-scale, seemingly negligible, events also affect the formation of risk preferences. In line with a reinforcement learning model, we...

We study how the distribution of other-regarding preferences develops with age. Based on a set of allocation choices, we can classify each of 717 subjects, aged 8 to 17 years, as either egalitarian, altruistic, or spiteful. Varying the allocation recipient as either an in-group or an out-group...
