In-group and Out-group motives in group conflicts: An experimental study

29 Jan 2019 - 2:00 pm - 3:00 pm

Abstract: Identity in a group conflict is a complex element. Being grouped with other people and engaging in a conflict against a rival group can generate group-related motivations, which may further depend on the social context of a given conflict. We disentangle different group-related motivations in an inter-group lottery contest over a public good prize. We develop our hypothesis based on a relative-payoff maximisation framework. Group-related motives are manipulated by matching participants’ decisions with pre-existing decisions from previous participants who are not going to be informed of the outcomes of the contest or receive any payoffs. Group of individuals contest each other in the standard treatment, so that in-group and out-group motives are simultaneously present. The group-motive manipulations are crossed with two identity conditions – concealed and revealed – to emphasize the role of social context. We do not find any difference in average contributions. Participants’ decisions in all treatments exhibit an inclination to avoid within-group exploitation and to match average contributions at both intra-group and inter-group levels.
