In recent years, the Italian judicial system has been at the center of both the political debate and policy
actions aiming at modifying the territorial structure and the organization of the courts as well as the procedural
processes. The measures adopted concerned the reorganization of the magistrates career and the
reform of judicial districts.
Despite the several reforms, the Italian judicial system does not reach yet the European standards,
principally for the so called magistrate-duration procedures binomial, according to which the number of

Network models provide a general representation of inter-connected system dynamics. This ability to connect systems has led to a proliferation of network models for economic productivity analysis, primarily estimated non-parametrically using Data Envelopment Analysis (DEA). While network DEA models can be used to measure system performance, they lack a statistical framework for inference, due in part to the complex structure of network processes.

This contribution is the first attempt to systematically review all empirical surveys that so far have been made available in the broad field of efficiency and productivity analysis using frontier estimation methodologies. We provide a systematic bibliometric review on the many empirical surveys in the field of efficiency and productivity analysis, the most relevant concepts, areas, overlaps, and potentials to explore from its introduction to the most recent surveys.

Non compensatory choices are widespread in the economics, strategic management and decision making. Nevertheless, many assessments of productivity still fail to consider non-compensatory preference structures in the measure of the technical inefficiency. This paper proposes a preference elicitation schema, typical of Multi-criteria decision analysis, for the selection of the directional vector in the assessment of a sustainable productivity.

Applying a two-stage Free Disposal Hull (FDH)/Tobit approach to a sample of 23 European countries, we find that the efficiency of social expenditure for families is positively correlated to per-capita GDP, population size, the education level of people, the weight and the ethics of the public sector.

Do European countries differ in the efficiency of their welfare policies? And which factors can
account for such variability? To address these questions, we perform a two-stage efficiency
analysis. First, based on a composite output indicator for social protection expenditure, we
measure efficiency by means of the Free Disposable Hull and Data Envelopment Analysis
techniques. Second, we perform an econometric analysis to identify the factors that can be
associated to cross-country differences. We find that countries scoring higher efficiency have
