Abstract

We study the impact of R&D and innovation on the use of external numerical flexibility(ENF). R&D and innovation imply both a higher average and a higher volatile productivity.We investigate this ambiguous effect on the firm preference for using ENF in two steps. First,we use a simple model to show that a first-order stochastic dominance shift in the distributionfunction increases the probability of hiring permanent workers, while a second-order shift hasambiguous effects. Next, using a dataset based on a survey of Italian manufacturing firms,we run logit regressions to estimate the effect of R&D and innovation on the probability ofemploying a fixed-term or a TWA worker, finding a positive and always significant effect.We also consider internal and external R&D and different types of innovation. Results showthat the former has a positive effect while the latter depends on the type of innovation.
