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...

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...

In this paper, I show that the trend in spatial inequality in Mozambique almost entirely explains the outstanding surge in inequality in the country over the past decade, as well as its decline immediately after the pandemic, in contrast to its secondary role in the earliest years. For this...
