I discuss the applicability of the recentered influence function (RIF) to the analysis of poverty differentials between distributions (regression-based decomposition into composition and income structure effects). I show that the predominant approach in the empirical literature estimates the...

This paper presents preliminary evidence of the annual global income distribution since 1950 using a new integrated dataset that aggregates standardized country income distributions at the percentile level estimated from various sources in the World Income Inequality Database. I analyse the...

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...

This paper investigates progress in reducing the high level of racial stratification of occupations after apartheid in South Africa. Empirical analysis, using census microdata and Labour Force Surveys, does not provide strong evidence of sustained or significant desegregation. Occupations remain...

We extend the conventional framework for measuring segregation to consider stratification of occupations by gender, i.e. when women or men are predominantly segregated into low-paying jobs. For this, we propose to use concentration curves and indices. Our empirical analysis using this approach...

In this paper, I show that occupations in South Africa are segregated and stratified not only by race, but also by gender. While some women (mostly black and Coloured) overwhelmingly fill low-paying jobs, others (mostly white and Indian/Asian but also Coloured) tend to fill higher-paying...

Despite the relevance of geographical disparities in India, earnings inequality occurs mostly within states, but with a broad range of variability in its levels. We investigate the sources of such variability using RIF decompositions of the inequality gaps between most populous states and India....

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...

In this paper, I quantify the contribution of a subpopulation to inequality. This is defined as the sum of the contributions of its members, with these contributions computed as the impact on inequality of a small increase in the population mass at each point of the distribution (using the...

This paper investigates inequalities across the major black ethnic groups in South Africa, accounting for 80 per cent of the country's population. We demonstrate that there is an important ethnic gap in the poverty levels of the Xhosa and the Zulu with respect to the Sotho/Tswana. We also show...
