This paper is concerned with the measurement of the relative poverty of people in different age groups in developing countries. In many instances it is useful to know, for example, whether a higher fraction of children are in poverty than are adults. However, it is difficult to make even simple...

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....

What are the determinants of the health and of well-being? Income and wealth are clearly part of the story, but does access to health-care have a large independent effect, as the advocates of more investment in health-care, such as the World Health Organization's Commission on Macroeconomics and...

In recent years, as longer time series of cross-sectional household surveys have become available, it has become possible to look at the consumption and saving behavior of birth cohorts in a number of developing and developed economies. The cohort evidence is singularly appropriate for the...

The World Bank prepares and publishes estimates of the number of poor people in the world. While everyone knows that these numbers should be taken with a pinch of salt, the numbers are arguably important. In an institution where the reduction of poverty is the paramount objective, some overall...
