Social identity is an important driver of behavior. But where do difierences in social identity come from? We use a novel laboratory experiment based on a revealed preference approach to analyze how individuals choose their identity. Facing a trade-off between monetary payments and belonging 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...

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...

This paper empirically analyzes how performance feedback and information on heterogeneity affect behavior in dynamic contests, using data on two-player-contests from a smartphone/tablet application called ``Wordblitz for Friends''. We find that players increase output as underdogs and decrease...
