The aggregate measures of inequality do not display any significant trend in the concentration of equivalent income among the Italian households in the early 2000s. Yet some sizeable shifts in the income distribution seem to suggest that the relative positions of groups of households have changed on the income scale. Through a decomposition analysis of Gini index by income source we find that in the more recent years the income from self-employment is the main disequalizing factor. The decomposition by social groups provides the evidence that it is the group of selfemployed and managers who have gained more ground on the income scale.

Abstract
The aggregate measures of inequality do not display any significant trend in the concentration of equivalent income among the Italian households in the early 2000s. Yet some sizeable shifts in the income distribution seem to suggest that the relative positions of groups of households have changed on the income scale. Through a decomposition analysis of Gini index by income source we find that in the more recent years the income from self-employment is the main disequalizing factor. The decomposition by social groups provides the evidence that it is the group of selfemployed and managers who have gained more ground on the income scale.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
