It is widely believed that while society allows technology to be private property, scientific knowledge is public and open. However, over the past quarter-century there has been increasing patenting of quite basic scientific knowledge. This essay argues that this is potentially a very serious...

This paper investigates the relationships between firm organization attributes, namely a structure á la Chandler, and their inward looking or exploitationʺ attitude in R&D and innovation. We argue that because of sunk costs and learning processes an inward looking behavior is a consequence of...

In this paper, we present an evolutionary model of industry dynamics yielding endogenous business cycles with 'Keynesian' features. The model describes an economy composed of firms and consumers/workers. Firms belong to two industries. The first one performs R&D and produces heterogeneous...

This paper discusses, first, the properties of scientific and technological knowledge and the institutions supporting its generation and its economic applications. The evidence continues to support the broad interpretation which we call the ʺStanford-Yale-Sussexʺ synthesis. Second, such...

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...

In this work we investigate two crucial dimensions of firms’ structure and dynamics, that is profitability and productivity performance. The empirical distributions and the associated persistence over time are explored through a set of parametric and non parametric exercises performed on an...

We present empirical evidence on diversification patterns in Italian manufacturing firms and detect a robust relationship between firm size and diversification levels, with an elasticity of diversification that does not depend on firm size and is well below unity. Diversification does not lead...

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...

In this paper, we perform an empirical comparison of Italian and US business cycles. After filtering the time series of the main macroeconomic variables of the two countries, through an approximate bandpass filter, we analyze the cross-correlations between each filtered variable and the filtered...

The goal of this study was to analyze the emergence of treatment standards associated with the adoption of anti-HIV drug innovations in the empirical setting of Italian clinical practice. Due to the rapid pace of technological change and the initial uncertainty concerning capabilities and...
