Abstract
In the framework of inequality measures decompositions, the paper introduces an immediate and straightforward simplification for the Gini index when a population is divided in two subgroups. Since one of the key points in inequality analysis is represented by the role of overlapping units, a simulation study is developed in order to analyze the effects of the overlapping component on inequality decomposition. Simple expressions for the measurement of either overlapping component and inequality between are derived, which allow to correctly evaluate and compare the effects of different factors on total inequality.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
