2000 Economic Report of the President:
Employer behaves as if minority worker’s true MRP is MRP-d where d is measure of employer prejudice against minority.
Firm pays for discrimination in the form of lower profits (CBGE).
Each worker’s productivity is measured with some error:
true productivity = measured productivity + error
If expected value of error depends on demographic group, can use group status to improve estimate of productivity.
As variance of error within a group rises, the value of discriminating on basis of group status is reduced.
Profitable to firm and may persist.
