This work explores the spatial structure of location of production activities. We try to disentangle location- from sector-specific drivers in the dynamic process of spatial agglomeration. We argue that the former typically apply "horizontally" (i.e. across all industrial sectors), while the...

In this paper we study a class of evolutionary models of industrial agglomeration with local positive feedbacks, which allow for a wide set of empirically-testable implications. Their roots rest in the Generalized Polya Urn framework. Here, however, we build on a birth-death process over a...

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...

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...

This paper provides a description of the production process by comparing different frameworks in which to analyze the relations between inputs and output. The analysis is performed on a representative sample of Italian manufacturing firms. We employ both parametric and non-parametric analysis....

It is widely accepted that in liberalized electricity markets log-returns display fat-tailed densities. Besides qualitative assessments, so far precise characterizations of the shape of the distribution have been seldom provided. In this work, we characterize the conditional and unconditional...

The study of firms' default has attracted wide interest among both practitioners and scholars. However, attention has often been limited to a relatively small set of financial variables. In this work, we try to increase the scope of analysis extending the investigation to other possible...
