The research on educational inequality plays an essential role in characterizing the fairness and effectiveness of educational systems, and monitoring and evaluating processes of educational development. This paper introduces a new quinquennial data set of educational inequality of 146...

Just as the Gini inequality index captures people's relative deprivation [Yitzhaki (1979)], so, we show in this paper, Gini-based progressivity and horizontal inequity indices capture individual perceptions of relative fiscal harshness and ill-fortune. In fact, we find that these links between...

We demonstrate how age-adjusted inequality measures can be used to evaluate whether changes in inequality over time are because of changes in the age structure. In particular, we explore the hypothesis that the substantial rise in earnings inequality since the early 1980s is driven by the large...

I analyze the effect of inequality on economic growth in Latin America, where inequality is measured as the area of family farms as a percentage of the total area of agricultural holdings. Using data from 18 Latin American countries between 1960 and 2004, I find that inequality has a nonlinear...

Based on Lewis’ dual-sector model, this paper explores a new mathematical model to evaluate income inequality between urban and rural residents quantitatively. Using the model, this thesis indicates that as the urban population increases, the income inequality between rural and urban residents...

Social stress can cause physical and mental harm. It is therefore not surprising that public health policy makers have sought to identify and implement policies aimed at tackling this social ill. A frequently prescribed remedy is to reduce social stress by reducing income inequality, which is...

The Gini coefficient is based on the sum of pairwise income differences, which can be decomposed into separate sums for individuals. Differences vis-à-vis poorer people represent an individual’s advantage, while those with respect to richer people constitute deprivation. Weighting deprivation...

The purpose of this research is to introduce a new approach to the decomposition of the Gini ratio into three components, supporting them with economic and statistical rigorous interpretations. The three components are: (i) the Gini inequality within subpopulations; (ii) the net contribution of...
