EN
Based on Palma’s observation that for empirical distributions within the range of the 4th and 9th deciles there are – with a good approximation – 50% of all goods, a new measure was introduced that is in a strong relationship to the Gini index, thus – supposedly – including all the information that it provides. In this paper this relationship is investigated more deeply for cases of some theoretical distributions as well as the relationship of a lower bound of a slightly differently defined ‘middle class’ on the Gini index.

Nowa miara nierówności, zaproponowana na podstawie spostrzeżeń Palmy, iż dla empirycznych rozkładów dochodów pomiędzy czwartym a dziewiątym decylem zawarte jest – z dobrym przybliżeniem – 50% wszystkich dóbr, okazuje się ściśle związana z indeksem Giniego, niosąc tyle samo co on informacji. W niniejszym artykule zależność ta analizowana jest dla pewnych rozkładów teoretycznych. Badana jest również zależność dolnej granicy „klasy środkowej”, zdefiniowanej nieco odmiennie od analogicznej klasy według Palmy, od współczynnika Giniego.
