We use a natural field experiment to investigate the hypothesis that generosity is partly involuntary, by examining whether individuals tend to avoid opportunities to act generously. In Sweden, new recycling machines for bottles and cans with an option of donating the returned deposit to charity...

This paper experimentally investigates the role of beliefs, trust, and risk in shaping cooperative behavior. By applying incentivized elicitation methods to measure these concepts, we find that beliefs about others’ behavior and trust are positively associated with cooperation in a public...

A growing number of experimental studies focus on the differences between the lab and the field. Important in this issue is the role of windfall money. By conducting a dictator game, where the recipient is a charity organization, in exactly the same way in the laboratory and in the field, we...

We experimentally investigate, using a dictator game, if the effects of windfall and earned endowments on behavior differ between men and women genders. In line with previous studies, we find that windfall endowments significantly increase the amount donated. The impact of moving from earned to...

This study investigates the validity of using stated preference (SP) estimates to predict policy effects on plastic bag consumption. Before implementation of a plastic bag regulation, when bags were still free of charge, we utilized an SP survey to elicit consumers’ contingent bag consumption...

In this paper we test the validity of choice experiments with donations for environmental projects. In particular, we test whether or not willingness to pay for projects differs between a hypothetical and an actual choice experiment. Our results do not indicate that choice experiments suffer...

When facing the opportunity to allocate resources between oneself and others, individuals may experience a self-control conflict between urges to act selfishly and preferences to act pro-socially. We explore the domain of conditional cooperation, and we test the hypothesis that increased...

We test the proposition that individuals may experience a self-control conflict between short-term temptation to be selfish and better judgment to act pro-socially. Using a dictator game and a public goods game, we manipulated the likelihood that individuals identified self-control conflict, and...

The social dilemma may contain, within the individual, a self-control conflict between urges to act selfishly and better judgment to cooperate. Examining the argument from the perspective of temptation, we pair the public good game with treatments that vary the degree to which money is abstract...

A growing literature in economics examines the development of preferences among children and adolescents. We combine a repeated dictator game with treatments that either provides participants with information about the average behavior of others or not. In a sample of 384 children aged 5-17, we...
