I estimate the average labor supply elasticity to the firm to be 1.08, however my findings suggest that there is significant variability in the distribution of firm market power across U.S. firms, and that dynamic monopsony models are superior to the use of concentration ratios in evaluating a firm's labor market power. I find that a one-unit increase in the labor supply elasticity to the firm is associated with earnings gains of between 5 and 16%. While nontrivial, these estimates imply that firms do not fully exercise their labor market power over their workers. Furthermore, I find that the negative earnings impact of a firm's market power is strongest in the lower half of the earnings distribution, and that a one standard deviation increase in the labor supply elasticity to the firm reduces the variance of the earnings distribution by 9%.
