The paper discusses the main issues related to negative and zero incomes that are relevant for the measurement of poverty. It shows the prevalence of non-positive incomes in high- and middle-income countries, provides an analysis of the sources and structure of these incomes, outlines the...

Incomes in surveys suffer from various measurement problems, most notably in the tails of their distributions. We study the prevalence of negative and zero incomes, and their implications for inequality and poverty measurement relying on 57 harmonized surveys covering 12 countries over the...

The chapter examines how the various dimensions of economic inequality between men and women are analyzed today. Beyond the gender wage gap—a central issue—and of course the still far from equal sharing of housework, the chapter also reviews research on gender inequality in access to...

This chapter reviews the empirical evidence on the levels and trends in income/consumption inequality and poverty in developing countries. It includes a discussion of data sources and measurement issues, evidence on the levels of inequality and poverty across countries and regions, an assessment...

Like the other chapters in this volume of the Handbook of Income Distribution (and its predecessor), the aim of this chapter is to provide a comprehensive review of a particular area of research. We examine the literature on post-1970 trends in poverty and income inequality, up to 2010 or 2011...

Recent research on Nigeria indicates declining income inequality. In contrast, anecdotal evidence suggests that only the upper class has benefited from economic growth in Nigeria overtime. The disconnect between these findings and anecdotal evidence, and the limitation in how inequality was...

The problem of land inequality has attracted renewed interest in the development literature due to its potential effects on the welfare of smallholder farmers. Poverty reduction is an important sustainable development goal and a clearer understanding of the factors that could lead to poverty is...

This study provides evidence on the trends and drivers of inequality in Vietnam using Vietnam Household Living Standard Surveys. We find that inequality, regardless of the choice of welfare indicators and inequality measurements, has been stable in Vietnam. Inequality in income or expenditure is...

Estimates of average per capita consumption and income from national accounts differ substantially from corresponding measures of consumption and income from household surveys. Using a new compilation of more than 2,000 household surveys matched to national accounts data, we find that the gaps...

The at-risk-of-poverty rate, the relative income poverty indicator applied in the EU, can be highly sensitive to the equivalence scale used to transform household income to an equivalent for individuals. This study applies two well-established approaches to estimate the equivalence scale: an...
