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...

In this paper, we estimate the recent evolution of global interpersonal inequality and examine the effect of omitted top incomes on the level and direction of global inequality. We propose a methodology to estimate the truncation point of household surveys by combining information on income...

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...

This paper estimates the distribution of personal wealth in South Africa by combining tax microdata, household surveys, and macroeconomic balance sheet statistics. We systematically compare estimates of the wealth distribution obtained by direct measurement of net worth, rescaling of reported...

We revisit trends in within-country income inequality using a newly integrated dataset that covers at least 70 per cent of the global population since 1980. We investigate absolute and relative inequality trends across the past four decades, combining the use of Lorenz curves with a set of...

Contrary to the popular notion that money that is easily earned, is also easily spent, economic theory holds that income is fungible. Drawing on the concept of mental accounting, this study theoretically explores when such a link between spending behaviour and the effort dispensed in obtaining...

The rights-based approach to development targets progress towards the realization of 30 articles set forth in the Universal Declaration of Human Rights. Progress is frequently measured using the multidimensional poverty index. While elegant and useful, the multidimensional poverty index is in...

This paper develops a new imputation methodology applied to missing incomes values in PNAD. PNAD is the main Brazilian household survey, but it has no imputation. The imputation process starts by fitting regression models applied to different income sources considering the complex sampling...

This paper explores the impact of the first wave of the COVID-19 pandemic in South Africa on income poverty and inequality in South Africa. Using a static tax-benefit microsimulation model with input datasets that were adjusted to reflect people's earned incomes just before the pandemic (March...

In this paper we explore South Africa's personal income tax system using two microsimulation models. The first, SAMOD, simulates personal income tax and social benefits using a dataset derived from the nationally representative National Income Dynamics Study survey. The second, PITMOD, simulates...
