Afternoon Must-Read: Arindrajit Dube, Laura Giuliano, and Jonathan Leonard: Fairness and Frictions: The Impact of Unequal Raises on Quit Behavior - Washington Center for Equitable Growth

At a large U.S. retailer… …discrete pay steps created discontinuities in raises, where workers initially earning within 1 cent of each other got raises that differed by 10 cents…. We find large causal effects of wages on quits…. The large effects of wages on quits mostly reflects relative-pay concerns and not market comparisons….

The relative-pay concerns are asymmetric… driven mainly by workers who are paid below their peers, suggesting concerns about fairness or disadvantageous inequity.
