This paper studies the impact of size on labor cost and productivity for Italian manufacturing firms. The distributions of both labor cost and productivity display a wide support, even when disaggregated by sector of industrial activity. Further, both labor cost and productivity, when considered...

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...

An agent-based model of a simple financial market with arbitrary number of traders having relatively general behavioral specifications is analyzed. In a pure exchange economy with two assets, riskless and risky, trading takes place in discrete time under endogenous price formation setting....

This work explores and compares some basic properties of corporate growth process at both aggregate manufacturing level and disaggregated sectoral levels. Using an extensive dataset on Italian manufacturing firms, we investigate which properties of firm growth dynamics are robust under...

This work analyzes the log-returns of daily electricity prices from the NordPool day-ahead market. We study both the unconditional growth rates distribution and the distribution of residual shocks obtained with a non-parametric filtering procedure based on the Cholesky factor algorithm. We show...

We analyze the endogenous price formation mechanism of a pure exchange economy with two assets, riskless and risky. The economy is populated by an arbitrarily large number of traders whose investment choices are described by means of generic smooth functions of past realizations. These choices...

The presence of excess covariance in nancial price returns is an accepted empirical fact: the price dynamics of nancial assets tend to be more correlated than their fundamentals would justify. We propose an intertemporal equilibrium multi{assets model of nancial markets with an explicit and...

The work studies the processes of growth of the world top 150 pharmaceutical firms, on the grounds of an original database which allows also disaggregate analysis at the level of single therapeutical classes and chemical entities.Our findings show that the industry -whose long-term evolution is...

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....

Since the seminal work of Pareto, many empirical analyses suggested that the distribution of firms size is characterized by an asymptotic power like behavior. At the same time, recent investigations show that the distribution of annual growth rates of business firms displays a remarkable...
