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...

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...

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...

– 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...

There is substantial empirical literature on the impact of climate vulnerability on economic outcomes in developing countries. However, this literature is still weak on the impact of climate vulnerability on tax revenue mobilization. To enrich the existing literature, this paper aims to investigate...

– 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)...

This paper investigates the effects of taxation on income inequality in an unbalanced panel of 45 countries in sub-Saharan Africa over the period 1980–2018. We use instrumental-variable two-stage least squares and instrumental-variable quantile regression estimates. We find that taxation widens...

Effective domestic revenue mobilization has gained renewed urgency, especially in the light of the need to recover from the COVID-19 pandemic. In taxation debates, the ‘informal sectors’ have hitherto been assumed to be a part of the problem and implicitly mistaken for lucrative tax bases. First, I...
