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...

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...

Empirical analyses on aggregated datasets have revealed a common exponential behavior in the shape of the probability density of the corporate growth rates. We present clearcut evidence on this topic using disaggregated data. We explain the observed regularities proposing a model in which the...

We introduce a new 5-parameter family of distributions, the Asymmetric Exponential Power (AEP), able to cope with asymmetries and leptokurtosis and at the same time allowing for a continuous variation from non-normality to normality. We prove that the Maximum Likelihood (ML) estimates of the AEP...

This work explores a number of properties investigated in the empirical literature on firm size and growth dynamics: (i) the distribution and the autoregressive structure of firm size; (ii) the existence of size-growth scaling relationships; (iii) the distribution and the autoregressive structure...
