چکیده

Lorenz curve and Gini index are the famous tools of income inequality. When one wants to study income inequality of a class of individuals, Partial Lorenz Curve is introduced and the corresponding measure of inequality called Partial Gini Index is defined. Partial Gini Index (PGI) is derived on Partial Lorenz Curve (PLC). Partial orderings are defined for comparison of partial Lorenz curves. For illustration purpose, real life data set of per capita Net State Domestic Product (NSDP) at current prices of States and Union territories of India are taken for the year 1998-99. Partial Gini Index is evaluated for three different classes of community and the results are discussed comparing with the Gini Index of the entire community. It is observed that Partial Gini Index gives more insight into the income inequality distribution between different classes of society.

Tsallis Maximum Entropy Lorenz Curves

In this paper, at first we derive a family of maximum Tsallis entropy distributions under optional side conditions on the mean income and the Gini index. Furthermore, corresponding with these distributions a family of Lorenz curves compatible with the optional side conditions is generated. Meanwhile, we show that our results reduce to Shannon entropy as $beta$ tends to one. Finally, by using ac...

Modeling multidimensional inequality in well-being: the case of Spain

The aim of this paper is to assess the evolution of multidimensional inequality in well-being using Lorenz curves. Closed expressions for the bivariate Lorenz curve defined by Arnold (1983) are given. We assume a relevant type of models based on the class of distributions with given marginals described by Sarmanov and Lee (Lee, 1996; Sarmanov, 1966). This specification of the bivariate Lorenz c...

Modeling inequality and spread in multiple regression

We consider concepts and models for measuring inequality in the distribution of resources with a focus on how inequality varies as a function of covariates. Lorenz introduced a device for measuring inequality in the distribution of income that indicates how much the incomes below the u quantile fall short of the egalitarian situation where everyone has the same income. Gini introduced a summary...
