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 conduct a real-effort task experiment where subjects' performance translates into a donation to a charity. In a within-subjects design we vary the visibility of the donation (no/private/public feedback). Confirming previous studies, we find that subjects' performance increases, that is, they...

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...

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...

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 analyse pricing, effort and tipping decisions in the online service "Google Answers" While users set a price for the answer to their question ex ante, they can additionally give a tip to the researcher ex post. In line with the related experimental literature we find evidence that tipping is...

The paper analyses the payment behaviour of customers of the online music label Magnatune. Customers may pay what they want for albums, as long as the payment is within a given price range ($5-$18). Magnatune’s comprehensive pre-purchase access facilitates music discovery and allows an...

Does geographic distance or the perceived social distance between subjects significantly affect proposer and responder behavior in ultimatum bargaining? To answer this question, subjects play a one-shot ultimatum game with three players (proposer, responder, and a passive dummy player) and...
