The paper is based on the idea that the organization of services by local authorities should take into account both the demographic features of the resident population and the spatial dimension of the territory involved. As regards the former, it seeks to identify homogeneous and spatially...

The use of bivariate cointegrated vector autoregressive models and Baba-Engle-Kraft-Kroner models ( Engle et al. 1995), is proposed for the selection of a stock portfolio (Markowitz type portfolio) based on estimates of average returns on shares and the volatility of share prices. The model put...

In this work we present space-time models with simultaneous effect in which the relations between phenomenon measured in different sites are not determined on the base of an a priori structure, but are estimated in the model’s estimation procedure. This approach avoids superimposition of a...

The aim of this paper is to study the relationship between reverse capital deepening and instability of the equilibrium between investments and savings. It is shown for a model with n commodities, infinitely many linear technique of production, and overlapping generation that a badly-behaved...

Least Orthogonal Distance Estimator (LODE) of Simultaneous Equation Models’ structural parameters is based on minimizing the orthogonal distance between Reduced Form (RF) and the Structural Form (SF) parameters. In this work we propose a new version – with respect to Pieraccini and Naccarato...
