We use the latest available data from the World Income Inequality Database 3.4 and the Penn World Tables 9.0 to examine some of the core issues and concerns that have animated research on global inequality. We begin by reviewing the evidence on trends in within-country inequality, drawing out some of the implications of this for our thinking about inequality and economic development. We examine between-country inequality, computing updated estimates of trends in both unweighted and population-weighted between-country inequality. The data reveal that inequality between countries increased across the latter half of the twentieth century, then turned to decline measurably thereafter. We show that this decline is robust to a range of methodological and measurement decisions identified as important in previous research. We then examine estimates of true global inequality, situating these in relation to lower- and upper-bound estimates of global inequality. We conclude by noting the critical and contested role of globalization in inequality reduction.

This study investigates the world income inequality between 1820 and 2008 decomposing international inequality into between- and within-region factors. Our estimates show increase of inequality between 1820 and the 1960s. Within-region inequality increased a lot in the very long run, mainly led by within-West inequality in nineteenth century and by within-East Asia inequality in the latter half of twentieth century. However, between-region inequality increased more significantly and was the main cause behind the very strong increase in global inequality in these two centuries. This process appears to have come to an end during the second half of twentieth century, a high level of stagnation of world inequality inthe 1970s and the 1980s followed by a decline inthe 1990s and more strongly in the 2000s, mainly due to the rapid growth in countries such as China, India, Indonesia, etc. This decline in world inequality was accompanied by decrease of between- and within-region inequality, although the speed of the former is faster than the latter.

While some scholars suggest that awareness of income inequality is strongest when the actual level of inequality is high, others find that individuals’ awareness of income inequality is largely unresponsive to actual inequality. In this article, we argue that individuals in different social class positions often respond to the actual levels of income inequality distinctively, and therefore a class perspective is essential in understanding how actual inequality and people’s perceptions of it are associated. Using data from the social inequality modules of the International Social Survey Programme (ISSP, 1992, 1999, and 2009) as well as the World Income Inequality Database ( https://www.wider.unu.edu/ ) and the World Inequality Database ( https://wid.world/ ), we consider how actual inequality interacts with social class to shape people’s perceptions of income inequality across 64 country-years between 1992 and 2009. We find that overall, perceptions of inequality are higher among the working class and lower among salariats. However, cross-nationally and over time, as the actual level of inequality increases, working classes become less critical toward inequality, whereas salariats become more critical. The actual level of inequality itself has no impact on people’s discontent toward it. This creates a counterbalancing effect that obscures the aggregate relationship between rising inequality and people’s perceptions of it.

This document is part of a series of technical notes describing the compilation of a new companion database that complements the World Income Inequality Database (WIID). It aims at facilitating the analysis of inequality as well as progress in achieving the global goal of reducing inequality within and across countries. This new dataset also includes an annual series reporting the income distribution at the percentile level for all citizens in the world, regardless of where they live, from 1950 to the present. This technical note describes the first stage in constructing the first version of the companion datasets: data selection. It provides an overview of the approach followed in the selection of the series from different sources with information on income distribution and inequality that best represent each country and period. It also discusses the general criteria used and their implementation, which are illustrated with a few country examples.

This review covers a range of measures and methods frequently employed in the empirical analysis of global income inequality and global income distribution. Different determinant factors along with the quantification of their impacts and empirical results from different case studies are presented. A number of issues crucial to the study of global income inequality are also addressed. These are the concepts, measurement and decomposition of inequality, the world distribution of income and inequality measured at different levels of aggregation:global, international and intra-national. We analyze income at each of these levels, discuss the benefits and limitations of each approach and present empirical results found in the literature and compare them with those based on the World Income Inequality Database. Research on world income inequality supports increased awareness of the problem, its measurement and quantification, the identification of causal factors and policy measures that affect global income inequality.

AbstractLiterature has established that, on a macroeconomic level, income inequality has a negative effect on average life satisfaction. An unresolved question is, however, which income groups are harmed by income inequality. In this paper we investigate this relationship at the microeconomic level combining national indicators of income inequality with individual data of life satisfaction from the World Values Survey for 39 countries over a period of 25 years. Tests on moderation by income category show that the Gini coefficient is most negatively related to life satisfaction of the lowest income groups, but the negative effects also extends to other income groups. For the income share of the top 1% we find a similar result. These findings show that income inequality is especially a concern for the lower income groups, but that the harmful effect of income inequality also spillovers to the life satisfaction of other income groups.

AbstractThis paper examines the relationship between public support for wage differentials and actual income inequality using data from the World Values Surveys. The distribution of income is more equal in nations where public opinion is more egalitarian. There is some evidence that the opinions of people with higher incomes are more influential than those of people with low incomes. Although the estimated relationship is stronger in democracies, it is present even under non-democratic governments, and the hypothesis that effects are equal cannot be rejected. We consider the possibility of reciprocal causation by means of an instrumental variables analysis, which yields no evidence that income distribution affects opinion.

This document is part of a series of technical notes describing the compilation of a new companion database that complements the World Income Inequality Database. It aims at facilitating the analysis of inequality as well as progress in achieving the global goal of reducing inequality within and across countries. This new dataset also includes an annual series reporting the income distribution at the percentile level for all citizens in the world, regardless of where they live, since 1950 to present. A previous note described the selection of income distribution series. Since these series may differ across welfare concepts and other methods used, this technical note describes the second stage, constructing integrated and standardized country series. It discusses all the necessary adjustments conducted to construct the final series for each country, with consistent estimates of the distribution of net income per capita over the entire period for which information is available. This is mainly divided into two stages. First, integrating country series by interlinking series that overlap over time, then using a more general regression-based approach.
