The Impact of Training on Productivity:
This paper investigates the e®ects of training on labor productiv-
ity using a unique nationally representative panel of Italian ¯rms for
the period 2002 to 2005. We ¯nd that training has a positive and
signi¯cant e®ect on productivity. Using a variety of panel estimation
techniques, we show that failing to account for unobserved heterogene-
ity leads to overestimate the impact of training on productivity, while
failing to account for endogeneity leads to substantially underestimate
it. Training also has a positive and signi¯cant impact on wages, but
this e®ect is about half the size of the e®ect on productivity. Within
occupational groups, the e®ect of training on productivity is large
and signi¯cant for blue-collars, but small and not signi¯cant for white
collars.

mance at both the micro and macro level. Despite the fact that a large
fraction of human capital accumulation takes place after the entry into the
labor market, most of the existing literature that investigates the returns
to investment in human capital has focused
