It has been argued that accountability is a public good that only citizens can provide. Governments can put institutions in place that allow citizens to hold public servants to account, but citizens must participate in those institutions if accountability is to be achieved. Thus, citizens face a...

Using an experiment with incentivized decisions of groups in the economics laboratory, I investigate the effect of group diversity on group risk taking. I measure econometrically the effects of various aspects of subjects’ diversity: nationality, language, university degree and gender. I...

We experimentally investigate how different information about others’ individual contributions affects conditional cooperators’ willingness to cooperate in a one-shot linear public goods game. We find that when information about individual contributions is provided, contributions...

Social preferences and social influence effects (“peer effectsâ€) are well documented, but little is known about how peers shape social preferences. Settings where social preferences matter are often situations where peer effects are likely too. In a gift-exchange experiment with...

This chapter presents some insights from basic behavioural research on the role of human pro-social motivation to maintain social order. I argue that social order can be conceptualised as a public good game. Past attempts to explain social order typically relied on the assumption of selfish and...

Laboratory experiments have become a wide-spread tool in economic research. Yet, there is still doubt about how well the results from lab experiments generalize to other settings. In this paper, we investigate the self-selection process of potential subjects into the subject pool. We alter the...

Some researchers have argued that anchoring in economic valuations casts doubt on the assumption of consistent and stable preferences. We present new evidence that questions the robustness of certain anchoring results. We then present a theoretical framework that provides insights into why we...

People self-assess their relative ability when making career choices. Thus, confidence in own abilities is likely an important factor for selection into various career paths. In a sample of 711 first-year students we examine whether there are systematic differences in confidence levels across...

The standard chicken game is a popular model of certain important real scenarios but does not allow for the escalation behaviour these are typically associated with. This is problematic if the critical, final decisions in these scenarios are sensitive to previous escalation. We introduce and...

This paper studies delegation without monetary transfers when the number of possible states is small, and therefore finite. To do so, we fully characterize the class of optimal delegation sets in the finite-state version of Holmstrom’s (1984) seminal model and analyze their properties. Our...
