This article proposes a subgroup decomposition of the determinants of the change in the Gini index over time. The decomposition allows one to explain the link between inequality change, reranking and income growth for the various subgroup components of the inequality index.

This paper proposes a decomposition of the change in inequality from the perspective of income groups. For every dichotomisation of the income distribution into poorer and richer parts, the decomposition allows to detect the change in the relative income gap between the two parts and the...

In Italia la regolamentazione del mercato del lavoro ammette che nel settore dei servizi per l’impiego operino intermediari sia pubblici sia privati. I servizi pubblici per l’impiego (SPI) esercitano la funzione di incontro domanda-offerta di lavoro secondo logiche differenti dagli operatori...

The literature offers two main ways of decomposing the Gini index: decomposition by population subgroup and by income source. This article proposes merging the two decomposition dimensions by suggesting a matrix formula for the Gini index which permits the simultaneous decomposition by subgroup...

Outsourcing is a useful tool for improving partnership between private and public companies. The budgetary constraints recently imposed by the Italian government on health industry are enhancing the urgency to outsource in order to cope the cost containment. Our study deals with the relationship...
