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 work is to estimate the structural parameters of a simultaneous equation system using both the Limited and Full Information Least Orthogonal Distance Estimator (Pieraccini, 1988; Naccarato, 2007). We compare the results - via simulation experiments – of LODE estimates with those...

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...

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...

ABSTRACT Some Remarks on the Shape of the Capital Demand and Supply Curves. The present paper is aimed at discussing some results concerning the choice of techniques and the capital theory in order to shed some light on aspects that might cause, and sometimes caused, a misunderstanding. We will...

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...
