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...

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...

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...

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 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...

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...

Using monthly data from the Understanding Society (UKHLS) COVID-19 Survey we analyse the evolution of unmet need and assess how the UK health care system performed against the norm of horizontal equity in health care access during the first wave of COVID-19 wave. Unmet need was most evident for...

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...

When developing anti-poverty policies, policymakers need accurate data on theprevalence of poverty. In this paper, we focus on subjective poverty, a conceptwhich has been largely neglected in literature, yet remains a conceptually appeal-ing way to define poverty. The primary goal of this study...
