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 this paper, we investigate the role of unequal opportunities and social group membership in preferences for redistribution. We present results from a large-scale online experiment with more than 4,000 participants. The experiment features a real-effort task and a subsequent dictator game with...

We investigate determinants of price expectations and satisfaction levels of financial professionals and students. In experiments with 150 professionals and 576 students, we systematically vary price paths according to the final return (positive or negative) and the way the final return is...

As the introduction of financial transaction taxes is increasingly discussed by political leaders we explore possible consequences such taxes could have on markets. Here we examine how “stylized facts”, namely fat tails and volatility clustering, are affected by different tax regimes in...
