A sense of identity can be a powerful influence over behavior, including work. Workers who identify themselves as belonging to one group may regard a job associated with a different group as a violation of their identity, especially if the job is associated with a group perceived to have lower social status. This identity channel may partly explain why some groups are over- or under-represented in some occupations. The identity-related mis-representation of groups in occupations leads to a misallocation of talent and cause economic inefficiency.
