Often in cooperative situations, many aspects of the decision-making environment are uncertain. We investigate how cooperation is shaped by the way information about risk is presented (from description or from experience) and by differences in risky environments. Drawing on research from risky...

The rejection of unfair proposals in ultimatum games is often quoted as evidence of other-regarding preferences. In this paper we focus on those responders who accept any proposals, setting the minimum acceptable offer (MAO) at zero. While this behavior could result from the randomization...

Many risky actions are carried out under the influence of alcohol. However, the effect of alcoholic intoxication over the willingness to take risks is complex and still remains unclear. We conduct an economic field experiment in a natural, drinking and risk-taking environment to analyze how both...

The ultimatum game (UG) is widely used to study human bargaining behavior and fairness norms. In this game, two players have to agree on how to split a sum of money. The proposer makes an offer, which the responder can accept or reject. If the responder rejects, neither player gets anything. The...

Experiments using economic games are becoming a major source for the study of human social behavior. These experiments are usually conducted with university students who voluntarily choose to participate. Across the natural and social sciences, there is some concern about how this...

The study shows that subjects who set their minimum acceptable offer equal to zero in an ultimatum game (UG) are the most generous dictators in a dictator game. The finding implies that interpreting indiscriminately the acceptance of low UG offers as payoff maximization can be misleading and...

We show that subjects who set their minimum acceptable offer to zero in an ultimatum game are the most generous players in a dictator game. This finding challenges the interpretation of the acceptance of low offers as payoff-maximizing behavior.

A natural field experiment is conducted on the determinants of consumer’s willingness to pay for “fair trade” (FT) products. In four treatments, subjects are offered different choices in connection with a coffee purchase, such as buying regular coffee or FT coffee at a premium, regular...

We analyze the effect of investments in corporate social responsibility (CSR) on workers’ motivation. In our experiment, a gift exchange game variant, CSR is captured by donating a certain share of a firm’s profit to charity. We are testing for CSR effects by varying the possible share of...

We investigate experimentally the underlying motivations and individual dierences with regard to the participation in between-group conflict in nested social dilemmas. In our nested social dilemmas, the collective is divided into two groups, and individuals allocate tokens between a private, a...
