Social Identity Theory

The concept of identity has become widespread within the social and behavioral sciences, cutting across disciplines from psychiatry and psychology to political science and sociology. Introduced more than fifty years ago, identity theory is a social psychological theory that attempts to understand person's identities, their sources in interaction and society, their processes of operation, and their consequences for interaction and society from a sociological perspective.

A revolutionary new understanding of identity, showing how our groups have a powerful influence on our feelings, beliefs, and behavior - and how these shared identities can inspire both personal change and social movements.

Identity Economics bridges a critical gap in the social sciences. It brings identity and norms to economics. People’s notions of what is proper, and what is forbidden, and for whom, are fundamental to how hard they work, and how they learn, spend, and save. Thus people’s identity—their conception of who they are, and of who they choose to be—may be the most important factor affecting their economic lives.
