Households regularly fail to make optimal financial decisions. But what are the underlying reasons for this? Using two conceptually distinct measures of time inconsistency based on bank account transaction data and behavioral measurement experiments, we show that the excessive use of bank...

A large body of evidence shows that social identity affects behavior. However, our understanding of the substantial variation of these behavioral effects is still limited. We use a novel laboratory experiment to measure differences in preferences for social identities as a potential source of...

We analyse data from a field setting in which students participate in a dynamic group contest with feedback. We combine this information with a laboratory measure of competitiveness. We find that competitive groups perform worse overall. In addition, we find that participants react to...

This paper tests social identity theory with respect to individuals' self-identification behavior. We report results from a laboratory experiment in which subjects choose their group membership, which is interpreted as decision to identify with the respective group. Inducing a trade-off between...

We model individual identification choice as a strategic group formation problem. When choosing a social group to identify with, individuals appreciate high social status and a group stereotype to which they have a small social distance. A group's social status and stereotype are shaped by the...
