Economists increasingly refer to monopsony power to reconcile the absence of negative employment effects of minimum wages with theory. However, systematic evidence for the monopsony argument is scarce. In this paper, I perform a comprehensive test of monopsony theory by using labor market...

We analyze optimal taxation in an economy with monopsonistic labor markets. The individuals, whose only decisions are whether to work, or not, have heterogeneous productivities and opportunity costs of work. Given its preferences for redistribution, the government, which does not observe the...

Over the last 30 years, researchers have disputed the mixed evidence of the effect of the minimum wage on teenage employment in the United States. Whenever the minimum wage has positive or no effects on employment, they appeal to monopsony models to explain their results. However, very few of...

Using a semi-structural approach based on a dynamic monopsony model, we examine to what extent workers performing different job tasks are exposed to different degrees of monopsony power, and whether these differences in monopsony power have changed over the last 30 years. We find that workers...

The primary goal of our paper is to quantify the importance of imperfect competition in the U.S. labor market by estimating the size of rents earned by American firms and workers from ongoing employment relationships. To this end, we construct a matched employeremployee panel data set by...

When jobs offered by different employers are not perfect substitutes in the minds of workers, employers gain wage-setting power; the extent of this power can be captured by the elasticity of labor supply that each employer faces. Estimates of this parameter reported by the literature vary...

Using linked employer-employee data which covers the majority of U.S. employment, I examine how frictions in the labor market have evolved over time. I estimate that the labor supply elasticity to the firm declined by approximately 0.19 log points (1.20 to 1.01) since the late 1990's, with the...

Guest workers on visas in the United States may be unable to quit bad employers due to barriers to mobility and a lack of labor market competition. Using H-1B, H-2A, and H-2B program data, we calculate the concentration of employers in geographically defined labor markets within occupations. We...

Using a semi-structural approach based on a dynamic monopsony model, we examine to what extent workers performing different job tasks are exposed to different degrees of monopsony power, and whether these differences in monopsony power have changed over the last 30 years. We find that workers...

This paper tests for and measures monopsony power in the U.S. higher education labor market. It does so by directly estimating the residual labor supply curves facing individual four-year colleges and universities using school-specific labor demand instruments. The results indicate that schools...
