Labor Market Concentration [PDF]
SSRN Electronic Journal, 2017 A product market is concentrated when a few firms dominate the market. Similarly, a labor market is concentrated when a few firms dominate hiring in the market. Using data from the leading employment website CareerBuilder.com, we calculate labor market concentration for over 8,000 geographic-occupational labor markets in the US.

INNOVATION AND MARKET CONCENTRATION WITH ASYMMETRIC FIRMS [PDF]
Economics of Innovation and New Technology, 2004 This paper considers a theoretical model of n asymmetric firms that reduce their initial unit costs by spending on R&D activities. In accordance with Schumpeterian hypotheses we obtain that more efficient (bigger) firms spend more in R&D and this leads to a more concentrated market structure.
