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...

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...

Three results emerge from a simple experiment on imitation. First, I find behavior which strongly suggests an intention to imitate. Second, players imitate successful other players rather than repeating successful actions. Third, to find imitation examples, players use several periods of memory....

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 first develop a theoretical framework to identify the factors that...

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

The paper introduces the concept of adjustment utility, that is, referencedependent utility from expectations. It offers an explanation for observed preferences that cannot be explained with existing models, and yields new predictions for individual decision making. The model gives a simple...
