Preference reversals with social distances Preference reversals between choice and valuation are typically studied with probabilities or with time delays. I extend them to social distances and document their existence in this new domain.
Are groups really more dishonest than individuals? with Lawrence Choo and Veronika Grimm A common finding of the literature on dishonesty is that groups are more dishonest than individuals. We revisit this finding by replacing the experimenter, implicitly hurt by subjects’ dishonesty, by an explicit third-party: a local charity. With the charity we do not find groups to be more dishonest than individuals. Instead, we find that groups can even help moderate the extent of dishonesty.
The stability of norms elicited with coordination games with Lawrence Choo and Veronika Grimm We investigate the stability of norms elicited with the Krupka-Weber norm-elicitation task. We define stability as norms being invariant to the experience, role, or type of subjects. We measure social norms in a game played among two teams who have different information regarding the size of a pie to be divided. We find that the norms are largely independent of these three aspects and conclude that social norms are indeed stable. This result further validates the use of this norm-elicitation task to measure norms.
