This paper explores the determinants of the heterogeneity in the expenditure behaviors of the Italian households, using the Households Expenditure Survey provided by the Italian National Institute of Statistics (ISTAT) for the year 2005. We assume that differences among consumers are associated...

The consumer price indexes for the entire country and those for individual households are weighted arithmetic averages of relative prices, and they differ essentially in terms of their weighting systems. Whereas the former use the proportions of total expenditure on goods and services, the...

Compulsory Communications system data contain important and so far under-investigated information on employment dynamics in Italy. They record all the activations, transformations, fixed-term extensions and anticipated terminations of employment relationships between any worker and employer...

This paper presents an empirical analysis of the response of several methods proposed in literature to construct indices for consistent multiple comparison. In this article we consider also the close formal connection between the comparison of preference judgements and the comparison of economic...

Utilizzando i risultati della recente indagine lstat-lsrds/Cnr sull'innovazione tecnologica in Italia, in questo lavoro vengono individuate, attraverso una cluster analysis, le principali tipologie settoriali dell'attivita' innovativa dell'industria manifatturiera italiana considerando,...

This paper aims to pursue two closely connected purposes. The first is to provide a theoretical framework, based on coherence constraints, for a technique of multicriteria analysis that allows to convert a partial pre-order into a total pre-order. The second it to show the possibility of...

The paper aims to analyse the behaviour of a battery of non-survey techniques of constructing regional I-O tables in estimating impact. For this aim, a Monte Carlo simulation, based on the generation of 'true' multiregional I-O tables, was carried out. By aggregating multi-regional I-O tables,...

In this paper, a new class of polarization measures is derived axiomatically. The concept of polarization is here identified with the decline of the middle class. In particular, we extend the definition of middle class towards a more realistic framework: the middle class is defined in terms of...

The ROC curve is one of the most common statistical tools useful to assess classifier performance. The selection of the best classifier when ROC curves intersect is quite challenging. A novel approach for model comparisons when ROC curves show intersections is proposed. In particular, the...
