How does group identity affect belief formation? To address this question, we conduct a series of online experiments with a representative sample of individuals in the US. Using the setting of the 2020 US presidential election, we find evidence of intergroup preference across three distinct...

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...

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...
