We compare the magnitude of local productivity advantages associated with two different spatial concentration patterns in Italy – urban areas and industrial districts. The former have high population density and host a wide range of economic activities, while the latter are marked by a high...

Using data from a large sample of Italian manufacturing firms we provide novel empirical evidence on the magnitude of local productivity advantages in two types of spatially concentrated regions: urban areas (UAs) and industrial districts (IDs). A larger surplus is estimated for cities compared...

In this paper we compare the magnitude of local productivity advantages associated to two different spatial concentration patterns in Italy, i.e. urban areas (UA) and industrial districts (ID). UA typically display a huge concentration of population and host a wide range of economic activities,...

We propose two indexes to measure the agglomeration forces acting within and between different regions. Unlike the existing measures of agglomeration, our model-based indexes allow for simultaneous treatment of both aspects. Local plant diffusion in a given industry is modelled as a spatial...
