Abstract

The present study was aimed to quantitatively investigate the income differentiation of the population using a new quantitative model proposed by the authors based on the different purchasing power of Rouble in the Russian regions. The main approach in this model is dividing the populations of the target region into needy and wealthy groups. All populations of Russia were rearranged from regional quintile groups into the all-Russian groups. The authors have compared the obtained results with the corresponding data of official statistics by the Gini coefficient and other statistical indicators. We have developed our model which is based on the division of the population of country into needy and wealthy groups in our previous studies and now it was used in this study for the real financial data. The calculations and recommendations on the redistributive overcoming of poverty at the expense of increase of the rate of surtax on the incomes of wealthy group are developed. The models of Pen, Lorenz, modified by the authors of the article, were applied in the research. The calculations were carried out for all subjects of the Russian Federation on the Russian State Statistical Service figures for the period of 2008-2013 years.
