Public enterprises are production units of goods or services under government control. In spite of wide privatizations in the last two decades, public provision in this form can be observed in many countries and sectors, particularly in education, health, transport, energy and environment. This...

The aim of the work is to reproduce the image of the research profile of the Italian statisticians derived from querying of bibliometric databases. We highlighted the need for multiple sources in order to convey a truer picture and how the data could be combined in order to have a classification...

We consider parametric hypotheses testing for multidimensional ergodic diffusion processes observed at discrete time. We propose a family of test statistics, related to the so called phi-divergence measures. By taking into account the quasi-likelihood approach developed for studying the...

The application of the Rasch model to measure the Quality and Customer Satisfaction of a service is possible only for a single dimension of the service. But we know that the Quality and Customer Satisfaction of a service are a compound of more than one dimension. In such a case the Rasch method...

Is privatization per se socially beneficial? Or do those benefits depend on the subsequent changes in the regulatory regime? In this paper, building on Vogelsang, Jones and Tandon (1994), we answer these questions by analyzing three different counterfactuals about British Telecom privatization...

In this paper we split up the sampling error occurred in stratified and clustering sampling, called global error and measured by the variance of estimator, in many partial errors each one referred to a single stratum or cluster. In particular, we study, for clustering sampling, the empirical...

Recently van De Van, Creedy and Lambert (2001) and Urban and Lambert (2008) have reconsidered the original Aronson, Johnson and Lambert (1994) decomposition of the redistributive effect in order to identify the optimal bandwidth that should be used in decomposing the redistributive effect when...

As in many other countries, government policy in the UK has the objective of raising the participation rate of young people in higher education, while increasing the share of the costs of higher education paid by students themselves. A rationale for the latter element comes from evidence of a...

Equilibrium and tâtonnement in Walras' Eléments Franco Donzelli Abstract Two alternative interpretations of the equilibrium notion employed by Walras in the Eléments and related writings have been recurrently suggested in the literature: a "stationary" interpretation and an "instantaneous"...

The EU Directive 2000/60/EC, also known as the “Framework directive in the field of water policy”, stresses the importance of water in human development processes and states that EU members should coordinate water policies towards a sustainable use of this resource; hence, water has a...
