Abstract This paper attempts to provide a new approach to social inequality, focusing on income and wealth inequality and the relationship between income inequality and wealth inequality. With an analysis of the data linking survey data with administrative data in South Korea, this paper reports that wealth, employment status, family size, and education are significant contributors to income inequality. However, income and loans are the two most significant factors contributing to wealth inequality. Income derived from economic activity and loans based on the leverage in the financial market have exacerbated wealth inequality as higher income groups tend to utilize more loans in the financialized economy, widening the gap between the rich and the poor. Wealth inequality has different dynamics from income inequality, mediated through leverage in South Korea.

Research and public conversations about income inequality and intergenerational mobility will benefit from a new approach that jointly visualizes these two measures. The new mobility table proposed addresses this concern by scaling each quintile by the spread of income it represents. Implications of this approach for future analyses of inequality and mobility are discussed.

Rising income inequality is a pressing political issue in Canada and internationally. Yet, policymakers in advanced economies have thus far failed to meaningfully address the issue. Tax policy is one of the primary tools available for governments to structure local distributive realities, but there is uncertainty regarding the ability of governments to take effective action in a globalized world economy. This policy brief puts forward viable reforms. The Canadian federal government can mitigate income inequality in Canada through targeted corporate and personal income tax reforms and a new approach to compliance enforcement.

Abstract In this work we apply a new approach to assess contributions from factor components to income inequality. The new approach is based on the insight that most (synthetic) inequality indexes may be viewed as (weighted) averages of point inequality measures, which measure inequality between population subgroups identified by income. Assessing contributions of factor components to point inequality measures is usually an easy task, and based on these contributions it is straightforward to define contributions to the corresponding (synthetic) overall inequality indexes as well. As we shall show through an analysis of income data from Eurostat’s European Community Household Panel Survey (ECHP), the approach based on point inequality measures gives rise to readily interpretable results, which, we believe, is an advantage over other methods that have been proposed in literature.

Financial development has been considered an efficient and effective mechanism for the sustainable economic growth and development of emerging markets in past decades. However, various concerns have emerged in relation to the influences of financial sector development on income inequality. It is the claim of this paper that findings from the current literature are incomplete. This is because various proxies have been utilized inconsistently for both financial development and income inequality in previous empirical studies. This study extends the current literature on this important finance–inequality nexus by examining a sample of 21 emerging countries for the period of 1961–2017. Various estimation techniques were employed with the aim of ensuring robust findings. Findings from this paper confirm the existence of an inverted U-curve relationship between financial development and income inequality, implying that income inequality may rise at the early stage of financial development and fall after a certain level is achieved. Policy implications have emerged from the findings of this study.

The article analyzes income inequality in the regions of the Ural Federal District using methodological innovations proposed by scientists from the Study Center of Sociocultural Changes at the Institute of Philosophy of the RAS and the Vologda Scientific Center of the RAS who introduced a family of income inequality centile coefficients into scientific circulation. These indicators characterize the ratio of incomes of the population various groups in the context of its depersonalized representative macrostrates.In the context of deepening economic inequality, the relevance of these innovations increases significantly, since in the current practice of identifying and analyzing the differentiation of the population incomes, a limited list of indicators is used, while the proposed new indicators make it possible to significantly expand the analytical possibilities of substantiating social policy. However, the complexity of the innovations application lies in the fact that the published statistical information does not allow directly calculating new characteristics. In this regard, the goal of the article is to substantiate and experimentally test a new toolkit that allows, on the basis of limited factual data, to determine the decile distribution of the regions population by the level of monetary income and to form the possibility of further calculating income weights and centile indicators of inequality. Experimental calculations were performed using the example of the Ural Federal District regions for 2000-2018. As a result of calculations and subsequent analysis, macrostrains of the supposed middle class with a stable share of monetary incomes in their total volume are identified that are stable over a long time. At the same time, the growth of inequality was mainly due to the redistribution of incomes from the low-income group in favor of the population part with the highest incomes.
