Departures from self-interest in economic experiments have recently inspired models of ?social preferences?. We design a range of simple experimental games that test these theories more directly than existing experiments. Our experiments show that subjects are more concerned with increasing...

Departures from "economic man" behavior in many games in which fairness is a salient characteristic are now well documented in the experimental economics literature. These data have inspired development of models of social preferences that assume agents have preferences for equity and efficiency...

We examine experimentally the impact of communication on trust and cooperation. Our design admits observation of promises, lies, and beliefs. The evidence is consistent with people striving to live up to others' expectations in order to avoid guilt, as can be modeled using psychological game...

Participants in experimental games typically can only choose actions, without making comments about other participants' future actions. In sequential two-person games, we allow first movers to express a preference between responder choices. We find that responder behavior differs substantially...

The question of whether lawyers and managers behave selfishly or fairly has inspired discussion for a long time. Empirical evidence, however, is sparse. Using data from an experiment with 359 law and business administration students, we investigate this question empirically and provide first...

In many different contexts individuals take decisions on the behalf of others. However, little is known about how this circumstance affects the decision making process and influences the ultimate individuals ́choices. In this paper, we focus on the context of investment decisions and study if...

There is much debate as to why economics students display more self-interested behavior than other students: whether homo economicus self-select into economics or students are instead “indoctrinated” by economics learning, and whether these effects impact on preferences or beliefs about...

This paper investigates experimentally whether risk attitudes are stable across social contexts. In particular, it focuses on situations where some resource (for instance, a position, decision power, a bonus) has to be allocated between two parties: the decision maker can either opt for sharing...

We show that people manipulate their attitudes towards ambiguity when doing so allows them to behave more self-interestedly. In a "dictator" decision subject chose between a "fair" and an "unfair" choice. By choosing the latter, dictators increase their own allocation by decreasing the...

We conduct a classroom survey to investigate the willingness to sacrifice consumption in absolute terms in order to ascend above others in terms of consumption levels. In contrast to other studies using survey methodologies, participants are divided into a treatment and a control group. This...
