This paper characterizes the cross-sectional and time-series properties of concentration in employment, job creation, and vacancy flows across U.S. local labor markets. We proceed in three steps: first, we derive conditions for indices of labor market concentration to be appropriate proxies for monopsony power. Then, we compute Herfindahl-Hirschman Indices at the local labor market level using data on the universe of online vacancies (BGT) and the universe of employers (LBD). Finally, we… 
Monopsony, Skills, and Labor Market Concentration1
This paper extends the literature on monopsony and labor market concentration by taking a skillbased approach and estimates the causal effect of monopsony power on labor market outcomes. The prior
Mergers and Acquisitions, Local Labor Market Concentration, and Worker Outcomes
Thousands of establishments employing millions of workers change ownership each year, sometimes leading to large changes in local labor market concentration that potentially increase labor market
Estimating Labor Market Power∗
How much power do employers have to suppress wages below marginal productivity? It depends on the firm-level labor supply elasticity. Leveraging data on job applications from the large job board

Labor Market Power
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 Concentration and Stayers' Wages: Evidence from France
We investigate the impact of labor market concentration on stayers’ wages, where stayers are defined as individuals who remain employed in the same establishment for at least two years. Using
ESMT Berlin and IZA
We build a model where firm size is a source of labor market power. The key mechanism is that a granular employer can eliminate its own vacancies from a worker’s outside option in the wage bargain.
Mitigating Monopsony: Occupational Mobility & Outside Options
To what extent are jobs in other occupations valuable outside options – and how does this mitigate monopsony power in concentrated labor markets? Using new data on occupational mobility from 16
Wages, Hires, and Labor Market Concentration
How does employer market power affect workers? We compute the concentration of new hires by occupation and commuting zone in France using linked employer-employee data. Using instrumental variables

The Rise of Market Power and the Macroeconomic Implications
We document the evolution of markups based on firm-level data for the US economy since 1950. Initially, markups are stable, even slightly decreasing. In 1980, average markups start to rise from 18%

Every time a local economy generates a new job by attracting a new business, additional jobs might also be created, mainly through increased demand for local goods and services. This positive effect
