New models of income distribution, graduation as the explanation of Gini coefficient

Abstract: The paper covers the new model of wage distribution in typical group of people. The model provides the opportunity to reparameterize applicable income distribution model: Pareto, logarithmically normal, logarithmically logistic, Dagum etc. The model ensures the graduation of Gini index values by polynomial degree of wage distribution as well as different types of income distribution. The given approach clarifies the nature of income inequality.
