Social habits to increasing inequalities of earnings

Summary/Abstract: In the article a hypothesis is formulated concering the social habit to increasing disproportions of earnings. The hypothesis is verified based on the economic growth model using data from 1970 to 2007. Econometric studies were carried out in two stages. The first stage covered estimating the optimal Gini coefficients for short sub-periods being moved increasingly in time. The second stage covered researches on the character of changes of the optimal Gini coefficients. In the studies we proved the hypothesis on the habit of society to increasing disproportions of earnings. The optimal Gini coefficients increase together with increasing economic level per capita and differences in earnings. The growth of the optimal Gini coefficient may be decreasing.
