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...

In this paper, we use the World Income Inequality Database to assess the main trends in inequality within countries since around 1990. We cope with the heterogeneity in the original information (regarding the measure of resources, equivalence scale, etc.) by focusing on the trends rather than on the...
The first of the Sustainable Development Goals (SDGs) is to end poverty in all its forms, everywhere. The monumental task — a long-time dream of humanity — is followed by 16 more goals under the 2030 Agenda. Though they are all interlinked, to even contemplate their achievement requires a deep well...
– And why it matters
More accurate estimates of inequality trends allow us to measure progress towards achieving reductions in inequality within and between countries. Deviations in trend patterns can provide insights for further explorations of the root causes and consequences of varying degrees of economic inequality...

– 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...

– 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)...

– An integrated approach
In large parts of the world, income inequality has been rising in recent decades. Other regions have experienced declining trends in income inequality. This raises the question of which mechanisms underlie contrasting observed trends in income inequality around the globe. To address this research...

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...

– The role of different parts of the income distribution
In this paper we reassess the relationship between inequality and human development, focusing on the differential effect associated with the concentration of national income at different parts of the income distribution. To do so, we rely on a large global panel of countries over the last decades...

– 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...

– Accounting for inequality changes in Spain during the recession
I discuss a new approach which decomposes inequality into the contributions of population groups by income sources. I estimate a matrix with rows and columns which indicate different population groups and income sources respectively, with each element indicating the marginal change in the inequality...

The author discusses a new approach which decomposes inequality into the contributions of population groups by income sources. The author estimates a matrix with rows and columns which indicate different population groups and income sources, respectively, with each element indicating the marginal...
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...

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...
