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...

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...

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...

Does geographic or (perceived) social distance between subjects signi?cantly affect proposer and responder behavior in ultimatum bargaining? To answer this question, subjects once play an ultimatum game with three players (proposer, responder, and dummy player) and asymmetric information (only...

In-group favoritism in social dilemma situations is one of the main findings of studies in Social Identity Theory. We investigate what causes the in-group bias: is it due to mere group affiliation or, alternatively, is guilt-aversion a possible explanation? We induce group membership in a...

The study of gender differences in social preferences has shown mixed results, preventing economists and other social scientists from drawing definitive conclusions on this topic. Several original investigations and experimental reviews have hypothesized that the main reason of this...

The literature on social preferences provides overwhelming evidence of departures from pure self-interest of individuals. Experiments show that people care about others' well-being and their relative standing. This paper investigates whether this type of behavior persists when risk comes into...
