– Relative and absolute perspectives
This paper presents the first global and regional estimates of polarization and bipolarization spanning the period 1960–2020. The study relies on group data to implement a flexible parametric model to obtain the global income distribution and polarization estimates. The study introduces a battery of...

Monitoring health is key for identifying priorities in public health planning and improving healthcare services. Life expectancy has conventionally been regarded as a valuable indicator to compare the health status of different populations. However, this measure is simply the mean of the...

– The contribution of the UNU-WIDER World Income Inequality Database initiative
Globally, there are several initiatives being undertaken to ensure the availability of information across countries that can be used to analyse the inequality phenomenon in and among countries. The data are easily accessible for use in comparative research on inequality across regions and countries...

– ACEIR research and the WIID
Work done by the African Centre of Excellence for Inequality Research (ACEIR) has documented the many-faceted nature of inequality in Ghana, Kenya, and South Africa. Conventionally measured inequality ranges from moderate (in Ghana) to extremely high (in South Africa). Trying to tell one coherent...

– Ghana case study
Over the years, money-metric measures of inequality such as the Gini coefficient and the Palma Ratio, as frequently used in Ghana, have become useful in providing quantitative measures of welfare distribution that enable a better understanding of the extent and nature of inequality. From these...

A substantial amount of research has been conducted examining inequality in South Africa using multiple data sources. We provide an overview of this research in this paper. Furthermore, we use nationally representative survey data to estimate income and consumption inequality in South Africa between...

pdf
This paper seeks to understand whether the way in which inequality is communicated through measurements influences individuals’ fairness perceptions regarding wealth inequality. It begins from the premise that prominent measures of inequality, such as the Gini coefficient, fall short of providing an...

– A k-means approach
This paper employs k-means clustering, a multidimensional pattern recognition method, to categorize countries using information from five Varieties of Democracy indices. K-means country clusters are similar but not entirely identical to both k-medians clusters and arbitrary groups formed using only...

In this paper we explore the links between international migration and income inequality. After presenting a simple model which considers the role of income distribution in individual decisions to migrate, we estimate a set of models on the determinants of yearly bilateral migration from a very...

– Examining the impact of relative income on formal and informal debt in South Africa
How does income inequality impact the propensity for and levels of formal and informal household debt? This paper assesses this question using the two most recent waves of the South African Living Conditions Survey. A range of linear models as well as a zero-inflated Poisson model are employed, and...

– Insights from wildfires across the globe
Natural disasters cause economic damages and may exacerbate disparities in income distribution among countries across the globe. This paper employs satellite data on real-time active fire locations to evaluate the short-term impact of forest fires on economic inequality around the world. Using quasi...

– A worldwide perspective
This paper investigates the importance of accounting for the profile of inequality in the analysis of institutional trust. Drawing on individual data from 82 countries around the world over the 1981–2021 period, it sheds light on the potential limitations of exploring the impact of the income...

– New evidence at the world level
This paper investigates the evolution of the productive structure around the world and the role it plays in the difference in inequality levels, using panel data for the period from 1995 to 2018. We approximate a country’s productive structure through the Economic Complexity Index. Our results...
Working Paper
pdf
The notion of multidimensional inequality has attracted attention lately, but mostly as a micro approach to measuring inequality in well-being in a more complete way. We argue that considering inequality in a multidimensional way from a macro perspective is useful for a better understanding of the...

– Command over tradables, non-tradables, and people
This paper analyses elite incomes around the world, and how international comparisons of elite incomes vary depending on the exchange rate and income concept used. It is well known that between-country income inequality is higher using market exchange rates than purchasing power parity (PPP)...

We examine inequality convergence over the past three decades and ask if environmentally related impacts on health, and their effect on human capital, are responsible for the slow rate of inequality reduction in countries. Though higher initial incidence of environmentally related impacts on health...
