Diverse theories of industry dynamics predict heterogeneity in production efficiency to be the driver of firms' growth, survival and industrial change, either through a direct link between efficiency and growth, or through an indirect effect via profitabilities, as more productive firms can...

This work explores the spatial distribution of productive activities in the Italian manufacturing industry. We propose an econometric model which tries to disentangle locationspecific from sectoral drivers in the dynamic process of spatial agglomeration. The basic idea is that the former...

Economies of agglomeration are central in understanding the emergence of industrial clustering. However, existing models that incorporate economies of agglomeration to explain industrial concentration have been providing a quite small set of empirically testable predictions. In this paper, we...

In this work we explore some basic properties of the size distributions of firms and of their growth processes both at aggregate and disaggregate levels. First, we investigate which properties of firm's size distributions and growth dynamics are robust under disaggregation. Second, at a...
