Sectoral Rates of Profit and Productive Structure

This paper analyzes an economic system in which rates of profit are not uniform but differ from one sector to another, and discusses the acceptable intervals of variation of the rates of profit compatible with non-negative prices. The investigation is conducted in a Leontief price model with fixed capital. The limits of variation of the rates of profit are ascertained using a mathematical algorithm based on the properties of Z matrices and dominant-diagonal matrices.     

Il modello input-output dei prezzi con capitale fisso: Aspetti economici e numerici

Questo lavoro analizza un modello dei prezzi con capitale fisso e propone un metodo numerico per determinare le sue soluzioni economiche. Il modello è applicato allo studio dell'andamento dei prezzi e del salario reale nell'economia italiana con riferimento al 1980. L'algoritmo proposto nel lavoro presenta alcune interessanti proprietà nell'ambito del calcolo parallelo.

Infrastructure and Performance of the Italian Economic System

This paper aims to analyze the consequences for the Italian economy of the recently started process of modernization and extension of the country's infrastructure. The planned measures are expected to increase the competitiveness of Italian businesses, and to improve the quality of life. In the short term, investments in infrastructure will increase the construction sector's production and, consequently, activate income and employment multipliers. The Italian economic system being highly differentiated from a territorial viewpoint, the impact of new investments on its economic system has been analyzed by means of a biregional model that accounts for the peculiar productive structure of the 20 Italian regions.     

PRODUCTIVE CAPITAL IN ITALY: A DISAGGREGATED ESTIMATE BY SECTORS OF ORIGIN AND DESTINATION: 1985–88

This study presents a series of matrices of the capital stock disaggregated both by branch of origin and by branch of destination for the years 1985 to 1988 for Italy. The tables, whose dimensions are 23 × 23, were constructed using the perpetual inventory method and are based on disaggregated time series of gross capital formation provided by Istat (Italian Statistical Institute). The tables refer to both gross and net capital (with straight-line depreciation) and have been tested on alternative hypotheses for the average expected service lives of capital goods and their survival functions.     

Modelling Intra-Group Relationships

Within a group of companies, a model is given for management of the relationships between the parent company and its subsidiaries. This is particularly relevant for groups originating from mergers and takeovers, because firms acquired often differ substantially in organizational structure from each other and from the parent company. The model provides a means of harmonizing the organizational structures of parent company and subsidiaries, so as to provide a complete coverage of necessary activities without duplication, and a means of identifying which activities should, in economic terms, be centralized by the parent company, and which should be delegated to the subsidiary. Finally, there is an empirical application of the model to one of the principal Italian banking groups.     

Input-Output for Management Control: The Case of GlaxoSmithKline

In this paper, we present an application of input-output analysis to management control and strategic planning for a pharmaceutical company. The model highlights the complex system of relationships between the different strategic business areas of the company and provides a tool for forecasting the dynamics of production, profits and internally shared services.
