March 2018Concentration in US Labor Markets: Evidence From Online Vacancy Data
with José A. Azar, Ioana Marinescu, Marshall I. Steinbaum: w24395
Using data on the near-universe of online US job vacancies collected by Burning Glass Technologies in 2016, we calculate labor market concentration using the Herfindahl-Hirschman index (HHI) for each commuting zone by 6-digit SOC occupation. The average market has an HHI of 4,378, or the equivalent of 2.3 recruiting employers. 60% of labor markets are highly concentrated (above 2,500 HHI) according to the DOJ/FTC guidelines. Highly concentrated markets account for 20% of employment. Many plausible alternative market definitions show that more than 40% of markets are highly concentrated, suggesting that employers have market power in many US labor markets.
