The Gini inequality index decomposition: an evolutionary study

First of all Rao (1969, p.42S) showed that if the Gini index, calculated on the basis of a distribution of incomes arranged by increasing order, is equal to R, then the index calculated on the basis of a distribution of incomes arranged in the opposite order will be equal to - R. Furthermore, if the distribution of income source) is a mixture of the two distributions that have just been mentioned, then this income source will have a neutral effect on total inequality.
