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...

Rankings are prevalent information and incentive tools in labor markets with strong competition for talent. In a dynamic model of multi-tasking and an accompanying experiment with financial professionals, we identify hidden ranking costs when performance in one task is incentivized and ranked...

Markets are ubiquitous in our daily life and, despite many imperfections, they are a great source of human welfare. Nevertheless, there is a heated recent debate on whether markets erode social responsibility and moral behavior. In fact, competitive pressure on markets may create strong...

Efficient coordination is a major source of efficiency gains. We study in an experimental coordination game with 718 children and teenagers, aged 9 to 18 years, the strategies played in pre-adulthood. We find no robust age effects in the aggregate, but see that smaller group sizes and larger...

In markets with asymmetric information between sellers and buyers, feedback mechanisms are important to increase market efficiency and reduce the informational disadvantage of buyers. Feedback mechanisms might work because of self-selection of more trustworthy sellers into markets with such...

Lack of information about COVID-19 and its spread may have contributed to excess mortality at the pandemic's onset. In April and May 2020, we implemented a randomized controlled trial with more than 3,000 households in 150 Bangladeshi villages. Our one-to-one information campaign via phone...

Social networks are a key factor of success in life, but they are also strongly segmented on gender, ethnicity, and other demographic characteristics (Jackson, 2010). We present novel evidence on an understudied source of homophily, namely behavioral traits. Behavioral traits are important...
