Relative deprivation is the experience of being deprived of something to which you think you are entitled. It has important consequences for both behavior and attitudes, including feelings of stress, political attitudes, and participation in collective action. This book assembles chapters by leading international researchers, who present innovative, integrative, theoretical and empirical advances in the area. It is relevant to researchers and students in social psychology, sociology, economics, politics, and other social sciences, especially those interested in intergroup relations, prejudice, social identity, group processes, social comparison, social justice, and social movements.
