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...

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...

This study assesses the evolution of inequality in Uruguay during 1981-2010, considered as subperiods built on the basis of the main policy regimes observed: extreme right (1981-84), centre-right (1985-89), right (1990-2004), and centre-left (2005-10). Income inequality diminished during the...

A recent trend in the study of poverty is to consider a relative poverty line, one that is responsive to the nature of the income distribution. We develop an axiomatic approach to the determination of an amalgam poverty line. Given a reference income (e.g. the mean or the median), the amalgam...

This paper evaluates the impact of education on measured inequality across the wage distribution using pooled records from the 2005 and 2010 Cameroon labour force surveys, wage equations and standard inequality measures. Returns to education increased monotonically. Yet incremental returns were...

This paper discusses different approaches to the measurement of global interpersonal in equality. Trends in global interpersonal inequality during 1975-2005 are measured using data from UNU-WIDER's World Income Inequality Database. In order to better understand the trends, global interpersonal...

This paper aims to advance understanding about the relationship between taxation and inequality in developing countries, focusing on the recent experience of Latin America. Although the tax system was regressive in the 1990s, tax changes promoted equality in the first decade of the 2000s. In...

Household budget surveys in sub-Saharan Africa are designed to facilitate poverty measurement and may fail to fully capture consumption in wealthy households. As a result, inequality is likely underestimated. We address upper tier consumption underreporting by aligning consumption derived from...

We analyse the evolution and proximate determinants of labour income inequality in Mexico between 1989 and 2017. Labour income inequality increased between 1989 and 1994 and declined between 1994 and 2006. What happened after 2006 is subject to uncertainty. The national labour force survey shows...
