This paper studies the construction of social preferences in the lab. Experimental subjects have the opportunity to donate to a charity and to allocate money in a conventional dictator game. The results show that charitable donations and dictator game allocations are positively correlated. The...

We run a public good experiment in the field and in the lab with (partly) the same subjects. The field experiment is a true natural field experiment as subjects do not know that they are exposed to an experimental variation. We can show that subjects' behavior in the classic lab public good...

To investigate the external validity of laboratory results, we combine a public good experiment with three treatments in a field experiment. One treatment offers the opportunity to free-ride, the other two are placebo treatments. We compare results within subjects. In the free-riding treatment,...

Economists have been theorizing that other-regarding preferences influence decision making. Yet, what are the corresponding psychological mechanisms that inform these preferences in laboratory games? Empathy and Theory of Mind (ToM) are dispositions considered to be essential in social...

In this study, we investigate how and why people discriminate among different groups, including their own groups and multiple out-groups. In a laboratory experiment, we use dictator games for five groups to compare actual transfers to in-group and out-group agents with the respective beliefs...

We use a range of dictator game experiments to investigate whether people avoid information altruistically. After learning about a product with positive externalities, a consumer may avoid learning the cost of the product so that she does not hesitate to act altruistically. We find that although...

Choosing what is morally right can be based on the consequences (ends) resulting from the decision - the Consequentialist view - or on the conformity of the means involved with some overarching notion of duty - the Deontological view. Using a series of experiments, we investigate the overall...

We investigate the external validity of giving in the dictator game by using the misdirected letter technique in a within-subject design. First, subjects participated in standard dictator games (double blind) conducted in labs in two different studies. Second, after four to five weeks (study 1)...
