Follow the majority? How voters coordinate electoral support to secure club goods

Voters often favor candidates who benefit them individually but may coordinate their support with their social group on other candidates in exchange for policies targeting their group. In a laboratory experiment, I induce group identities to investigate the behavior of voters facing such trade-offs. I find that groups with low within heterogeneity often secure the club good from a candidate who is also individually beneficial to a majority of the group. In more heterogeneous groups, coordination on that candidate often fails and while the group still receives club goods, it is from a candidate whose policies are otherwise individually costly to most of the group. The results highlight the role strategic considerations play in the formation of group-based electoral coalitions.
