A new method for constructing R&D capital stocks is proposed. Following Schumpeter, the development of R&D capital stocks is modelled as a process of creative destruction. Newly generated knowledge is assumed not only to add to the existing R&D capital stocks but also, by displacing old...

We examine endogenous growth through vertical innovations in a two region model with partial regional and varietal knowledge spillovers. This paper extends the growth literature by adding a regional endogenous growth model with improvements in product quality, instead of a product variety engine...

A new approach is developed to measure knowledge spillovers by means of proportion of non-appropriable returns to social returns, assuming no specific forms of production and knowledge functions. It is complicated theoretically, but very simple and practical empirically. Using PWT 6.3, we find...

Our data from 351 innovating firms for the years 2001–2012 generally suggest that patentable ideas are strongly linked to the mobility of individual inventors, or that the knowledge flows transmitted are sticky inventor-specific. In other words, the larger the knowledge pool of an inventor...

This paper investigates the impact of regional sectoral diversity on regional employment growth in Italy over the period 1991-2001. Assuming that externalities may be stronger between industries selling similar products or sharing the same skills and technology (i.e. related industries), we...

Empirical results on the link between growth and diversity in (un)related industries proved to be highly dependent on the specific regional and temporal context. Making use of highly disaggregated employment data at the sub-regional level, we find that higher employment growth in Austria is...

This paper applies functional regression to precise geo-coded register data to measure productivity spillovers from high-skilled workers. We use a smoothing splines estimator to model the spatial distribution of high-skilled workers as continuous curves. Our rich panel data allows us to address...
