In 2012 a labour market reform, known as Fornero Law, substantially reduced firing restrictions for firms with more than 15 employees in Italy. The results from a difference in regression discontinuities design that compares firms below versus those above the cut-off before and after the reform demonstrate that, after the Fornero Law, the number of trained workers increased in firms just above the threshold, with an order of magnitude of approximately 1.5 additional workers in our preferred empirical specification. We show that this effect might be partly explained by the reduction in worker turnover and a lower use of temporary contracts at the threshold after the reform. Our study highlights the counter-intuitive and potentially adverse effects of employment protection legislation (EPL) on training in dual labour markets due to larger firms seeking to avoid the higher costs of EPL by means of temporary contracts.
