Replication Data for: The Impact of Group Identity on Coalition Formation

Bargaining and coalition building are a central part of modern politics. We argue that majoritarian bargaining is important for the formation of coalitions and that group-identity preferences impact partner selection. We test the effect of gender, race and ideological distance in a majority-rule bargaining experiment and find that ideological distance significantly affects the likelihood and amount offered to potential partners. We conclude that formateurs need not be purely rational actors pursuing policy goals and/or the benefits of office. Rather, they also care about the identity of their partners, preferring others who are like themselves.
