Most of the measures income inequality are derived from Lorenz curve, and many authors state that Gini index is best single measure inequality. The present paper reviews some theorical properties curve provides a nonparametric estimate almost sure convergence this estimate. And to confirm performance estimator, an application on real data was carried out.

background: maternal mortality (mm) is an avoidable death andthere is national, international and political commitment to reduceit. the objective of this study is to examine the relation of mm tosocioeconomic factors and its inequality in iran’s provinces at anecologic level.methods: the overall mm from each province was considered for3 years from 2004 to 2006. the five independent variables wh...

This paper surveys alternative ways of expressing the Gini mean difference and the Gini coefficient. It adds some new representations and new interpretations of Gini's mean difference and the Gini coefficient. All in all, there are over a dozen alternative ways of writing the Gini, which can be useful in developing applications to Gini-based statistics. Mailing Address: Department of Economics ...

This paper introduces the concept of Pigou-Dalton transfers between populations of income receivers. Gini’s mean difference and Dagum’s Gini index between populations are axiomatically derived in order to gauge the impact of withinand between-group PigouDalton transfers on Dagum’s measure. We show its sensitiveness for any given transfer in the sense that inequality-reducing transfers are captu...

We have developed a satellite data derived “Night Light Development Index” (NLDI) as a simple, objective, spatially explicit and globally available empirical measurement of human development derived solely from nighttime satellite imagery and population density. There is increasing recognition that the distribution of wealth and income amongst the population in a nation or region correlates str...

The Gini index represents a special case of the generalized Gini indices, which permit to choose a level of inequality aversion and to stress the different proportions of the income distribution. In order to apply these indices to income sample data, it is necessary to use reliable inferential procedures. In fact, also if often in income studies we have large samples for which the precision of ...

INTRODUCTION One of the main weaknesses of the health system in Turkey is the uneven distribution of physicians. The diversity among geographical districts was huge in the beginning of the 1960s. After the 1980s, the implementation of a two-year compulsory service for newly graduated physicians is an interesting and specific experience for all countries. The aim of this study is to analyse the ...
