We study the relation between people's personal values and environmentally friendly consumption behavior. We first assessed subjects' personal values using the Aspiration Index. Then subjects participated in a laboratory supermarket offering organic and conventional food products and different...

We investigate to what extent genuine social preferences can explain observed other-regarding behavior. In a dictator game variant subjects can choose whether to learn about the consequences of their choice for the receiver. We find that a majority of subjects showing other-regarding behavior...

We conduct a modified dictator game in order to analyze the role self-image concerns play in other-regarding behavior. While we generally follow Konow (2000), a cognitive dissonance-based model of other-regarding behavior in dictator games, we relax one of its assumptions as we allow for...

By now there is substantial experimental evidence that people make use of "moral wiggle room" (Dana et al., 2007), that is, they tend to exploit moral excuses for selfish behavior. However, this evidence is limited to dictator games. In our experiment, a trust game variant, we study whether...

Recent research has cast some doubt on the general validity of outcome-based models of social preferences. We develop a model based on cognitive dissonance that focuses on the importance of self-image. An experiment (a dictator game variant) tests the model. First, we find that subjects whose...

A central understanding in experimental economics is that subjects’ decisions in the lab are independent of history. We test whether this assumption of between-experiment independence is indeed justified. We analyze experiments with an allocation decision (like a dictator or ultimatum game)...

Using a laboratory experiment, we examine whether voluntary monetary sanctions induce subjects to coordinate more efficiently in a repeated minimum effort coordination game. While most groups first experience inefficient coordination in a baseline treatment, the efficiency increases...

The higher our aspirations, the higher the probability that we have to adjust them downwards when forming more realistic expectations later on. This paper shows that the costs induced by high aspirations are not trivial. We ?rst develop a theoretical framework to identify the factors that...
