This paper estimates the causal impact of dismissal costs on capital deepening and
productivity exploiting a reform that introduced unjust-dismissal costs in Italy for firms
below 15 employees, leaving firing costs unchanged for larger firms. We show that the
increase in firing costs induces an increase in the capital-labour ratio and a decline in
total factor productivity in small firms relative to larger firms after the reform. Our results
indicate that capital deepening is more pronounced at the low-end of the capital
distribution - where the reform hit arguably harder - and among firms endowed with a
larger amount of liquid resources. We also find that stricter EPL raises the share of
high-tenure workers, which suggests a complementarity between firm-specific human
capital and physical capital in moderate EPL environments.
