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...

The key challenge in making distributional comparisons with ordinal data is the lack of commensurability of the distances between the ordered categories. This chapter provides a critical review of the most recent theoretical developments addressing this challenge and providing methods for...

A growing literature uses repeated cross-section surveys to derive ‘synthetic panel’ data estimates of poverty dynamics statistics. It builds on the pioneering study by Dang, Lanjouw, Luoto, and McKenzie (Journal of Development Economics, 2014) providing bounds estimates and the innovative...

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 Greek economic crisis resulted in a decline in household disposable income by more than 40%. Even though all population groups lost income in absolute terms, some were substantially more severely hit by the crisis. The paper examines the effect of the crisis on the population shares, the...

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...

Panel data are rarely available for developing countries. Departing from traditional pseudo-panel methods that require multiple rounds of cross-sectional data to study poverty mobility at the cohort level, we develop a procedure that works with as few as two survey rounds and produces point...

The Greek crisis was the deepest and longest ever recorded in an OECD country in the postwar period. Output declined by over a quarter and disposable income by more than 40%, while the unemployment rate exceeded 27%. The paper explores the effects of the crisis on the level and the structure of...

In many developing countries, the increasing public interest in monitoring economic inequality and mobility is hindered by the scarce availability of longitudinal data. Synthetic panels based on matching individuals with the same time-invariant characteristics in consecutive cross-sections have...

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...
