%0 Report %A Webber, Douglas A. %T Firm Market Power and the Earnings Distribution %D 2013 %8 2013 Apr %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 7342 %U https://www.iza.org/publications/dp7342 %X Using linked employer-employee data, I compute firm-level measures of the labor supply elasticity facing each private non-farm firm in the US. I provide the first direct evidence of the positive relationship between a firm's labor supply elasticity and the earnings of its workers. I also contrast the dynamic model method employed by this paper with the more traditional use of concentration ratios to measure a firm's labor market power. Finally, I construct a counterfactual earnings distribution which allows the effects of firm market power to vary across the earnings distribution. %K monopsony
