This paper studies the impact of changes in educational opportunities on various definitions of labour market inequalities in Brazil over two decades (1976-96). Using four editions of the nationally representative PNAD survey, we analyze the evolution of overall inequalities and inequalities of...

This work takes a new look at the econometrics of the national-level macroeconomic relationship between inequality and growth. It focuses, in particular, on the effects of specification choices, estimation method and sample selection. It concludes that there is no robust relation running from...

This paper examines for the first time inequality of opportunity for income in Africa, by analyzing large-sample surveys, all providing information on individuals' parental background, in five comparable Sub-Saharan countries: Ivory Coast, Ghana, Guinea, Madagascar and Uganda. We compute...

A new analysis of large-sample surveys in five comparable Sub-Saharan African countries allows measuring for the first time inequality of opportunity in Africa, aside inequality of resources and of living standards. We confirm the prevalence of high levels of inequality among the region’s...

The purpose of our paper is to derive instructive analytics on how to account for differentials in demographic variables, and in particular mortality, when performing welfare comparisons over time. The idea is to “correct” in various ways estimated income distribution measures for “sample...
