We consider the notions of static and dynamic reasonableness of requests by an authority in a trust game experiment. The authority, modelled as the experimenter, systematically varies the experimental norm of what is expected from trustees to return to trustors, both in terms of the level of...

Observing that people who wish to engage in prosocial behavior are often presented with more than one means to the same end, we develop a model in which agents may contribute to a single public good through a range of different activities. We use this model to make two points. First, noting that...

Purchases of voluntary carbon offsets (VCOs) are growing tremendously. At the same time, the number of activities and products for which VCOs are available is increasing. Experts discuss whether offering VCOs is exclusively associated with positive effects on the environment or if it instead may...

Potential environmental benefits of green tariffs may be mitigated if households increase electricity consumption after they subscribe to green tariffs. Using metered data of household electricity consumption from a large provider of green electricity in Germany, our quasi-experimental analysis...

This paper studies the dynamic effect of observability on prosocial behavior. We hypothesize a twofold positive effect. First, people should act more prosocially when being observed. Second, this increased level of prosociality should motivate an ongoing elevated altruistic attitude, in...

Literature in economics and psychology on moral behaviour explores the contexts in which people act in ways that are consistent or inconsistent with their past actions. Such inconsistencies appear to violate economists' assumption of rational consumer behaviour. In this note we show that a...
