We experimentally study the relationship between other-regarding preferences, group identity and political participation. In doing so, we propose a novel group identity induction procedure that succeeds in creating environments where in-group bias is either high or low. At the individual level, we find that both altruistic subjects and group identifiers participate above average. The most competitive subjects participate much less often than other types, while the most altruistic subjects manage to sustain high participation levels. At the aggregate level, we observe only few statistically significant differences between environments where group identity is high and low. This suggests that the higher participation observed in field settings for close-knit (political) groups might be due to underlying mobilization processes rather than a heightened sense of group-belonging.
