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...

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...

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 ï¬nd that a majority of the people...

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

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

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...

In economic theory, utility depends on past, present and future outcomes. The experiment described in this paper suggests that utility also depends on people's attitudes, and that it can easily be manipulated through these attitudes. The results imply, ?rst, that purely outcome-based models of...
