In traditional economic models, individuals have one overriding motivation: utility.

Whereas a utility-maximizing model emphasizes what one wants, an identity-based model might emphasize what one believes they should want — because of who they are.Rachel Kranton is the James B. Duke Professor of Economics at Duke University, where she specializes in how institutions and social forces affect economic outcomes.
