Concentration in U.S. local labor markets: evidence from vacancy and employment data

  title={Concentration in U.S. local labor markets: evidence from vacancy and employment data},
  author={Claudia Macaluso and Brad J. Hershbein and Chen Yeh},
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


Strong Employers and Weak Employees: How Does Employer Concentration Affect Wages?
We analyze the effect of local-level labor market concentration on wages. Using plant-level U.S. Census data over the period 1977–2009, we find that: (1) local-level employer concentration exhibits
The Decline of the U.S. Labor Share
Over the past quarter century, labor’s share of income in the United States has trended downward, reaching its lowest level in the postwar period after the Great Recession. A detailed examination of
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%
The Fall of the Labor Share and the Rise of Superstar Firms
The fall of labor's share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in
Local Multipliers
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
Labor Market Concentration, Earnings Inequality, and Earnings Mobility
Using data from the Longitudinal Business Database and Form W-2, I document trends in local industrial concentration from 1976 through 2015 and estimate the effects of that concentration on earnings
Skill remoteness and post-layoff labor market outcomes
This paper quantifies the effects of discrepancies between local supply and demand for skills on wages, employment, and mobility rates of laid-off workers. I propose the concept of local skill
Labor Market Flows in the Cross Section and Over Time
Estimating the Firm’s Labor Supply Curve in a “New Monopsony” Framework: Schoolteachers in Missouri
In the context of certain dynamic models, it is possible to infer the elasticity of labor supply to the firm from the elasticity of the quit rate with respect to the wage. Using this property, we
Markups and Firm-Level Export Status
Estimating markups has a long tradition in industrial organization and international trade. Economists and policy makers are interested in measuring the effect of various competition and trade
