Private Equity and Workers: Modeling and Measuring Monopsony, Reallocation, and Trust

By: Kyle Herkenhoff, Josh Lerner, Gordon M. Phillips, Francisca Rebelo and Benjamin Sampson

We measure the real effects of private equity buyouts on worker outcomes by building a new database that links transactions to matched employer-employee data in the United States. To guide our empirical analysis, we derive testable implications from three theories in... View Details

Discrimination, Rejection, and Job Search

By: Anne Boring, Katherine Coffman, Dylan Glover and María José González-Fuentes

We investigate how candidates’ willingness to apply responds to (potential) discrimination and rejection using a simulated labor market. Past work has shown that “blinding” job applications reduces discrimination and increases the rate at which women are hired. Our... View Details
