In modern society the income distribution is one of the major problems. Usually, it is considered that a severe polarisation in matter of income per capita could have a major negative impact on the general process of economic development. This study is focussing on estimating dynamics of some...

Social scientists study two kinds of inequality: inequality between persons (as in income inequality) and inequality between subgroups (as in racial inequality). This paper analyzes the mathematical connections between the two kinds of inequality. The paper proceeds by exploring a set of...

This article analyzes the mathematical connections between two kinds of inequality: inequality between persons (e.g., income inequality) and inequality between subgroups (e.g., racial inequality). The authors define a general inequality parameter in two-parameter continuous distributions. This...

The `Vast majority of incomes ratio (VMIR)' $R_0$ is the ratio of the average income $\mu_0$ of a poorest majority $p_0$ of the population to the overall average income $\mu$. Another measure of equality is $E_0\equiv(1-G)$ where $G$ is the Gini coefficient of inequality of the distribution....
