– Measurement, trends, impacts and policies
Many low- and middle-income countries are achieving good rates of economic growth, while high inequality remains a priority concern. Some countries meanwhile have low growth, high inequality, and pervasive poverty—often linked to their fragility. There is now active debate on how countries should...

The existing literature on optimal taxation typically assumes there exists a capacity to implement complex tax schemes, which is not necessarily the case for many developing countries. We examine the determinants of optimal redistributive policies in the context of a developing country that can only...

– Evidence from Brazil and South Africa
Human capital models imply that both the distribution of education and returns to education affect earnings inequality. Decomposition of these ‘quantity’ and ‘price’ components have been important in understanding changes in earnings inequality in developed and developing countries. This paper...

This paper evaluates fairness in educational achievements through the ordered pair (WEEOp, IEOp) whose components provide: (i) A measure of social welfare which accounts for the achievement of less-advantaged pupils and (ii) a synthetic index of inequality in educational opportunities. Students’...

– New Evidence from Individual Income Tax Returns
This paper presents new evidence on the study of income mobility in Ecuador over the period 2004–11. We utilize longitudinal data of individual income tax returns to measure income mobility both at the top and at the middle of the income distribution, and we find three main empirical results. First...

The paper proposes an analysis of the recent distributional dynamics in Uganda. This analysis is performed by endorsing an opportunity egalitarian perspective, in order to evaluate the outcome dynamics of specific groups of the population and infer the role of growth in the evolution of inequality...

– Study on the Inequality–Development Relation Using Top Income Shares Data
This paper uses recently published top 1% income share series in studying the inequality– development association. The top income shares data are of high quality and cover about a century for some countries and thus provide an interesting opportunity to study slow development processes. The...

– The Case of Botswana 1921-2010
In Sub-Saharan Africa we find some of the highest levels of income inequality in the world. Nevertheless, we generally know very little about the historical development of inequality. In this paper we look at how inequality developed in colonial and post-colonial Botswana. We show that income...

– Do Poor South Africans Underestimate Their Health Needs?
Researchers often rely on household survey data to investigate health disparities and the incidence and prevalence of illness. These self-reported health measures are often biased due to information asymmetry or differences in reference groups. Using the World Health Organization study on global...

– Anonymous Versus Panel Income Approaches
We reconcile, both theoretically and empirically, changes in inequality with panel income changes over periods of economic growth and decline. We also explore what factors account for the trends of short-run inequality and of inequality in individual average earnings. Finally, we explore what...

– 1983 to 2009-10
This paper undertakes an assessment of the evolution of inequality in the distribution of consumption expenditure in India over the last quarter-century, from 1983 to 2009-10, employing data available in the quinquennial ‘thick’ surveys of the National Sample Survey Office. We find that plausible...

We study a model of human capital driven growth, where the parent’s human capital serves as a productive input in the child’s human capital production only when that of the former exceeds a minimum level required to intellectually contribute to the child’s learning. Private and public expenditures...

The paper reviews the extent of the income inequality decline that took place in Latin America in 2002-10 and then focuses on the factors that may explain such decline. These include a lowered skill premium following an expansion of secondary education among the poor, and the adoption of more...

The new UTIP-UNIDO (University of Texas Inequality Project-United Nations Industrial Development Organization) dataset of industrial pay inequality has 4...

We present a unified structural equation modelling framework for the regression-based decomposition of rank-dependent indicators of socioeconomic inequality of health and compare it with a simple ordinary least squares regression. The structural equation modelling framework forms the basis for a...

– How Much is too Much?
A key aspect defining the contemporary income distribution is the (increasing) share the top holds compared to the rest. This paper shows that income concentration increases towards the very top of the distribution, while the shares the middle- and upper-middle-income groups hold, remain stable...
