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...

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...

Actual behaviour is influenced in important ways by moral emotions, for instance guilt or shame (see, among others, Tangney et al., 2007). Belief-dependant models of social preferences using the framework of psychological games aim to consider such emotions to explain other-regarding behaviour....

We assess the empirical validity of the overall theoretical framework of other-regarding preferences by focusing on those preference axioms that are common to all the prominent theories of outcome-based other-regarding preferences. This common set of preference axioms leads to a testable...

In three party ultimatum games the proposer can first decide whether to exclude one responder, what increases the available pie. The experiments control for intentionality of exclusion and veto power of the third party. We do not find evidence for indirect reciprocity of the remaining responder...

We analyse two types of belief-dependant models of social preferences: guilt aversion and reciprocity. In particular, we test the relevance of their input variables (second-order beliefs and general dispositions for guilt/reciprocity). The data confirm the predictions of belief-dependant models....

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...

Customers of the online music label/store Magnatune can pay what they want for albums as long as the payment is within a given price range ($5-$18). On average, customers pay significantly more than they have to. We ran an online survey and collected responses from 227 frequent Magnatune...

We augment a standard dictator game to investigate how preferences for an environmental project relate to willingness to limit others' choices. We explore this issue by distinguishing three student groups: economists, environmental economists, and environmental social scientists. We find that...

Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively-colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss important extensions of the standard...
