Taking the initiative is a crucial element of leadership and an important asset for many jobs. We assess this element of leadership in a game in which it emerges spontaneously since people have a non-obvious possibility to take the initiative. We can show that leadership in this game correlates...

An apology is a strong and cheap device to restore social or economic relationships thathave been disturbed. In a laboratory experiment we find that harmdoers use apologies inparticular if they fear punishment and when their intentions cannot be easily inferred. Afteroffenses with ambiguous...

An apology is a strong and cheap device to restore social or economic relationships that have been disturbed. In a laboratory experiment in which apologies emerge endogenously, we find that harmdoers use apologies in particular if they fear punishment and if their intentions cannot be easily...

We investigate whether risk, time, environmental, and social preferences affect single family homeowners' investments in energy efficient renovations and energy quality of their house using established experimental measures and questionnaires. We find that homeowners who report to be more risk...

We provide experimental evidence on how unequal access to performance enhancing education affects demand for redistribution. People earn money in a real effort experiment and can then decide how to distribute it among themselves and another subjects. We compare situations in which randomly...

Field evidence suggests that people belonging to the same group often behave similarly, i.e., behaviour exhibits social interaction effects. We conduct an experiment that avoids the identification problem present in the field. Our novel design feature is that each subject simultaneously is a...

We provide a direct test of the role of social preferences in voluntary cooperation. We elicit individuals' cooperation preference in one experiment and make a point prediction about the contribution to a repeated public good. This allows for a novel test as to whether there are types of players...

We provide a test of the role of social preferences and beliefs in voluntary cooperation and its decline. We elicit individuals' cooperation preferences in one experiment and use them as well as subjects' elicited beliefs to explain contributions to a public good played repeatedly. We find...
