The Effect of Learning by Hiring on Productivity
Pierpaolo Parrotta ()
and Daio Pozzoli ()
Abstract: This work studies the phenomenon of inter- rm labor
mobility as potential channel of knowledge transfer. Using data from the
Danish employer-employee register, covering the period 1995-2005, it
investigates how the knowledge embed- ded into recruited workers, coming
from other rms, contributes to the process of knowledge di usion and boosts
rms productivity. Speci cally, estimating both parametric (Cobb-Douglas)
and semi-parametric production functions (Olley and Pakes, 1996; Levinsohn
and Petrin, 2003), the impact of recruited technicians and highly educated
workers on total factor productivity at the rm level is found to be signi
cantly positive. A matching analysis, which allows for contin- uous
treatment e ect evaluation (Hirano and Imbens, 2004), corroborates this
nding.
