The estimation method of Two Stage Least Squares (2SLS) with Principal Components (2SPC) is applied to a medium-sized nonlinear econometric model of the Italian Economy.

This paper is a survey (in Italian) of the estimation methods for econometric systems of nonlinear simultaneous equations

In this paper we argue that energy efficiency and environmental efficiency are two aspects of the same problem. To show this, we assess the analytical utility of the well-known IPACT and ImPACT models, presenting here a new developed identity named Augmented ImPACT. For Italy, our findings...

The purpose of this study was to investigate the contributions of Social Identify Theory’s variables to research performance. Regression models were applied on data of ten national research Council (Cnr) institutes of Piemonte, a highly industrialised region in North Western Italy.Results show...

Given a set of continuous variables with missing data, we prove in this paper that the iterative application of a simple “least-squares estimation/multivariate normal simulation” procedure produces an efficient parameters estimator. There are two main assumptions behind our proof: (1) the...

Industrial districts palyed a very important role in the Italian economic development. This paper provides fresh evidence based on microdata (Veneto Worker Histories) and discusses the ambiguities in the district definition, its uncertain boundaries and the development into territorial...

The study of structural changes is the theme of this work, where structural changes are correlated primarily with changes in the structure of production, which are caused by the evolution of technical progress and organizational changes in production. The analysis of models and theories of...

This issue of the journal Sinergie collects papers presented at the conference held in Urbino in April 2005 on "The internationalization of small business and industrial districts", organized by the Faculty of Economics, Urbino University. The initiative was an opportunity to reflect on a theme,...

Three industrial organization (IO) models suggested by Dornbusch (1987) are here adapted to study the labor-cost effects on relative prices of tradable goods between the regions of a monetary union. The assumption of imperfect and segmented goods and labor markets makes the analysis best suited...

The paper analyzes the evolution of the trade specialization patterns in Italy and its main trade partners (France, Germany, and the United States). In the methodological section we discuss the effectiveness of the Lafay index as an indicator of specialization. We then propose some modifications...
