Abstract
As individuals, we define our group identities by categorizing others and ourselves into many social categories like gender, race, religion, nationality, political convictions, and profession, among many others. This categorization process confers us a notion of “who” we are, which social groups we belong, and more importantly, how we are expected to behave. This thesis revolves around two phenomena at the core of group identity literature; discrimination and intergroup conflicts. Group identity is considered an underlying factor of discriminatory behaviors and the emergence of conflicts between members of social groups. There is extensive evidence showing that the mere categorization into social categories is enough to trigger discrimination against members of other social groups. Moreover, human history provides many examples of conflicts and genocides rooted in group identity diversity more than in economic disputes. However, not all social group members discriminate in the same magnitude, nor all social groups are involved in conflicts. The first paper of this thesis proposes an empirical measure that goes beyond categorizing individuals into social categories. Using willingness to acquire representative goods of social groups, this paper measures and quantify group identity intensity to investigate reinforcing and attenuating factors of group identity. The results found provide evidence on how convergence and divergence in behaviors among social group members reinforce and attenuate the group identity intensity of individuals, which is crucial in predicting the emergence of intergroup conflicts at the collective level and strong degrees of discrimination at the individual level. The literature studying the effects of group identity on individual decision-making has largely focused on studying discrimination and intergroup conflicts assuming individuals’ group identity is known and observable. However, many group identities rely on convictions and beliefs that are not directly observable from individual physical traits, and therefore, might be uncertain (e.g. religion, ideology). The second paper presented in this thesis explores the effects of group identity uncertainty on discrimination patterns when individuals decide whom to interact with and its repercussions on collective coordination efficiency. Managing group identity diversity and uncertainty is a major factor in determining organizations and firms' profit and success, especially when a diverse workforce might find it difficult to coordinate and cooperate. The results found in the second paper shed light on the role group identity uncertainty plays in individual interaction preferences and offer several managerial insights for deterring discrimination among employees to interact and increase their coordination efficiency when working in teams. Finally, the last paper presented in this thesis, contributes to the literature of policies and interventions aimed at mitigating discrimination and prejudices between members of social groups in conflict. While this literature has focused on studying how the contact between members of different social groups reduces discrimination and prejudices, there is a lack of evidence on interventions with same purposes not requiring contact between individuals.
The last paper presented in this thesis exploits a natural occurring context in which individuals of two social groups currently in conflict see themselves forced to cooperate in order to achieve a superordinate common goal without being able to get in contact. This context offers the opportunity to put the emphasis not in the contact between individuals but in the superordinate common goals as a mitigating factor of discrimination. Results show that individuals got more selfish as the superordinate common goal was gradually achieved. Furthermore, individuals from one social group also increased their discrimination as the common goal was gradually achieved. These results highlight superordinate common goals mitigate discrimination and selfishness.
