Affirmative Action: One Size Does Not Fit All

American Economic Journal: Microeconomics. 2016. Vol. 8. No. 2. P. 215-252.
Krishna K., Tarasov A.

This paper identifies a new reason for giving preferences to the disadvantaged using a model of contests. There are two forces at work: the e§ort e§ect working against giving preferences and the selection e§ect working for them. When education is costly and easy to obtain (as in the U.S.), the selection e§ect dominates. When education is heavily subsidized and limited in supply (as in India), preferences are welfare reducing. The model also shows that unequal treatment of identical agents can be welfare improving, providing insights into when the counterintuitive policy of rationing educational access to some subgroups is welfare improving.
