While the labor market implications of mergers have been historically ignored as "out of market" effects, recent actions by the Department of Justice (DOJ) place buyer market power (i.e., monopsony) at the forefront of antitrust policy. We develop a theory of multi-plant ownership and monopsony...

We contribute a theory in which three channels interact to determine the degree of monopsony power and therefore the wedge between a worker's spot wage and her marginal product (henceforth, the wage markdown): (1) heterogeneity in worker-firm-specific preferences (nonwage amenities), (2) firm...

We contribute a theory in which three channels interact to determine the degree of monopsony power and therefore the markdown of a worker's spot wage relative to her marginal product: (1) heterogeneity in worker-firm-specific preferences (non-wage amenities), (2) firm granularity, and (3) off-...

We develop a tractable quantitative, general equilibrium, oligopsony model of the labor market that we use to measure the macroeconomic implications of labor market power. Strategic interaction complicates inference of parameters that are key to this exercise. To address this challenge, we...

What are the welfare implications of labor market power? We provide an answer to this question in two steps: (1) we develop a tractable quantitative, general equilibrium, oligopsony model of the labor market, (2) we estimate key parameters using within-firm-state, across-market differences in...

Theoretically, monopsony power of the firms relative to their workers can come in many forms, each causing wages to be less than marginal revenue products of labor, but each having different welfare and policy implications. These include worker-firm specific amenities, search frictions, the...
