Experimental and field evidence show that people perceive and evaluate new risks differently from risks that are common. In particular, people get used to the presence of certain risks and become less eager to avoid them. We explain this observation by including risks in the reference states of...

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....

Private banks often blame state guarantees to distort competition by giving public banks the advantage of lower funding costs. In this paper I show that if borrowers perceive the public bank as supporting economic development, private banks may be able to separate firms by self selection, enter...

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...

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...

In experimental economics there exists a lively debate about the independence of observations. Although opinions on the issue differ widely, all concerns regard the independence of subjects' behavior within one session or experiment. This paper attempts to shed some light on the independence of...

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...

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...

Using a laboratory experiment, we examine whether informal monetary sanctions can lead to better coordination in a repeated minimum effort coordination game. While most groups first experience inefficient coordination, the efficiency increases substantially after introducing an ex post...

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...
