Изучается взаимосвязь инфляции и неравенства на основе информации Росстата по российским регионам. Методология эконометрического моделирования включает идентификацию отдельных панельных регрессий для индекса потребительских цен (ИПЦ) и коэффициента Джини, а также систему уравнений для указанных показателей, в том числе инфляции на продовольственные, непродовольственные товары и услуги, а также квинтилей распределения населения по доходам. Показано, что между ИПЦ на товары и услуги и коэффициентом Джини по регионам имеется двусторонняя положительная связь. Результат асимметричен и характерен для ИПЦ на продовольственные товары и для пятого квинтиля по доходам населения. Для ИПЦ на непродовольственные товары и услуги, а также первого квинтиля распределения по доходам связь отрицательная двусторонняя. Полученные результаты позволяют учитывать неравенство населения по доходам при принятии решений Банком России по монетарной политике, а также подчеркивают эффективность правительственных мер по выравниванию доходов населения для сдерживания инфляционных процессов.

The paper examines the question of whether inflation and inequality are interrelated. The data panel formed based on Rosstat information. The econometric modeling methodology included the identification of separate panel regressions for the consumer price index (CPI) and the Gini coefficient, as well as equations systems for these indicators, including equations systems for food inflation, nonfood products and services, as well as quantiles of population distribution by income. A two-way positive relationship between the CPI for goods and services and the Gini coefficient by region was empirically obtained. However, the result is asymmetric and typical for the CPI for food products and for the fifth income quintile. For the CPI for non-food goods/services/the first quintile of the income distribution, the result changes to a negative two-way relationship. The obtained results allow taking into account the unequal income of the population when making decisions by the Bank of Russia on monetary policy, as well as emphasize the effectiveness of government measures to equalize income of the population in order to contain inflationary processes.
