ABSTRACT

The decomposition of an income inequality index is a topic that has been and still is of great interest to researchers (e.g., economists, econometricians and statisticians) because of its operational importance. In fact it can be used to detect the possible causes of inequality itself and, if used with due attention, it could be a valid tool in the hands of policy-makers when evaluating, for instance, measures aiming at reaching a more egalitarian income distribution.
