Economic and social interaction takes place between individuals with heterogeneous characteristics. We investigate experimentally the emergence and informal enforcement of different contribution norms to a public good in homogeneous and different heterogeneous groups. When punishment is not...

We analyze equilibria of two-player contests where players have intention-based preferences. We find that players invest more effort compared to the case with selfish preferences and are even willing to exert effort when the monetary value of the prize converges to zero. As a consequence,...

In psychological games, higher-order beliefs, emotions, and motives - in addition to actions - affect players' payoffs. Suppose you are invited to a party, movie, dinner, etc not because your company is desired but because the inviter would feel guilty if she did not invite you. In all of these...

We conduct experimental games with police applicants in Germany to investigate whether intrinsically motivated agents self-select into public service. Our focus is on trustworthiness and the willingness to enforce norms as key dimensions of intrinsic motivation in the police context. We find...

Although both economists and psychologists seek to identify determinants of heterogeneity in behavior, they use different concepts to capture them. In this review we first analyze the extent to which economic preferences and psychological concepts of personality - such as the Big Five and locus...

To study how information about educational inequality affects public concerns and policy preferences, we devise survey experiments in representative samples of the German population. Providing information about the extent of educational inequality strongly increases concerns about educational...

Private information is at the heart of many economic activities. For decades, economists have assumed that individuals are willing to misreport private information if this maximizes their material payoff. We combine data from 72 experimental studies in economics, psychology and sociology, and...

We summarise our two sets of controlled experiments designed to see if single-sex classes within coeducational environments modify students’ risk-taking attitudes. In Booth and Nolen (2012b), subjects are in years 10 and 11, while in Booth, Cardona-Sosa and Nolen (2014), they are first-year...
