Focusing model and preference reversals across domains Similar anomalies have been documented in risky choice, intertemporal choice, and choice across social distances. I explain this similarity with the focusing model of Kőszegi and Szeidl (2013). The model gives a unique explanation to the common ratio effect, the common difference effect, the common social distance effect, and magnitude effects. It also provides a characterisation of procedural preference reversals between choice and valuation. I confirm in a laboratory experiment the existence of these preference reversals with social distances.
Are social norms universal? with Lawrence Choo and Veronika Grimm We investigate whether people perceive the same social norms despite having different interests or a different understanding of a social situation. 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 compare the norm reported by subjects who acted in different roles, who had different experiences, and who are of different types. We find that the norms are largely independent of these three aspects and conclude that social norms are indeed universal. This result also validates the use of a norm-elicitation task to reveal the social norms.
Are groups really more dishonest than individuals? (available soon)
with Lawrence Choo and Veronika Grimm To investigate whether groups are more dishonest than individuals we conduct a laboratory experiment where dishonesty harms a local charity. Contrary to existing experimental literature on group versus individual dishonesty, we find that groups are no more dishonest than individuals. In fact, groups can help moderate the extent of dishonesty.
