Equilibrium Effects of Pay Transparency in a Simple Labor Market: Extended Abstract

Public discourse on pay transparency has not focused on equilibrium effects: how greater transparency impacts hiring and bargaining. To study these effects, we combine a dynamic wage-bargaining model with data from online markets for low-skill, temporary jobs that differ in their level of transparency. Wages are more equal, but lower under transparency. Transparency increases hiring and employer profits, rising 27% in an online field experiment. A key intuition is high transparency commits employers to negotiating aggressively, because a highly paid worker's salary affects negotiations with other workers. We discuss implications for the gender wage gap and employers' endogenous transparency choices.
