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 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...

Abstract: This paper is aimed at discussing Mandler’s interpretation of Sraffa’s price theory. In particular we will analyse Mandler’s idea that an institutional determination of distribution, suggested by Sraffa, could be solidly advanced only in the case of equilibrium price...

Malinvaud (2003) observed that once techniques are ranked according to Hick’s concept of average period for a given rate of interest, a rise in the latter entails the use of a technique with a shorter average period. After a reconstruction of Malinvaud’s argument, it is shown that the result...

In questo scritto si discutono tre questioni relative alla teoria della rendita assoluta: 1) una possibile reinterpretazione delle ipotesi che Marx pone alla base della sua teoria della rendita assoluta; 2) le differenze tra la rendita assoluta e la rendita da monopolio; 3) la possibilità di...
