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...

This paper estimates the number of poor in various countries in Asia by applying an "amalgam poverty line", which is a weighted average of an absolute poverty line (such as $1.25 per day or $1.45 per day) and a reference income (such as the mean or the median income). The number of poor is...

In this paper we make a methodological proposal to measure poverty accounting for time by proposing a new index that aims at reconciling the way poverty is measured in a static and a dynamic framework. Our index is able to consider the duration of the poverty spell and the social preference for...

This chapter reviews definitional issues that arise in assessing the extent of, and change in, poverty in western industrialized countries, including the choice of resource, level of poverty line and appropriate adjustments for the size and type of the income-sharing unit. The chapter also...

I discuss the measurement of world poverty and inequality, with particular attention to the role of PPP price indexes from the International Comparison Project. Global inequality increased with the latest revision of the ICP, and this reduced the global poverty line relative to the US dollar....

A particular scale-invariant index of poverty is subjected to careful analysis. This leads to a new perspective, not seen before, on the family of subgroup-consistent and scale-invariant poverty indices. Parametric families of new poverty indices are presented which offer the analyst a degree of...

Many empirical studies have shown that economic growth generally leads to a drop in poverty. These studies have also pointed out that a given growth rate is compatible with a large range of outcomes in terms of poverty reduction. This means that growth is more pro-poor in certain cases than in...
