Identity Politics and Trade Policy.Ā Elhanan Helpman, October 2, 2018, Paper, “We characterize trade policies that result from political competition when assessments of wellbeing include both material and psychosocial components. The material component reflects, as usual, satisfaction from consumption. Borrowing from social identity theory, we take the psychosocial component as combining the pride and self-esteem an individual draws from the status of groups with which she identities and a dissonance cost she bears from identifying with those that are different from herself.Link
