From creativeness to innovativeness: a firm-level investigation

This paper assesses the existence of knowledge externalities in the form of creative human capital spillovers that affect firm innovative performance. Relying on a large sample of Italian manufacturing firms, a knowledge production function is estimated and the residuals regressed on regional creative workforce indicators interacted with spatial agglomeration variables and measures of knowledge transmission mechanisms. The estimates show that regional density of creative human capital has a positive effect on firm innovativeness only after a critical mass is achieved and only after accounting for the presence of local universities, industrial districts and entrepreneurial activities related to knowledge-intensive services.
