The authors analyze the relationship between ethnic polarization and the duration of civil wars. Several recent papers have argued that the uncertainty about the relative power of the contenders in a war will tend to increase its duration. In these models, uncertainty is directly related to the...

Institutional features of the African setting -- large extended families and imperfect credit and land markets -- matter to the equity and efficiency roles played by intergenerational linkages. Using original survey data on Senegal that include an individualized measure of consumption, this...

Public knowledge about India's ambitious Employment Guarantee Scheme is low in one of India's poorest states, Bihar, where participation is also unusually low. Is the solution simply to tell people their rights? Or does their lack of knowledge reflect deeper problems of poor people's agency and...

Prevailing measures of relative poverty put an implausibly high weight on relative deprivation, such that measured poverty does not fall when all incomes grow at the same rate. This stems from the (implicit) assumption in past measures that very poor people incur a negligible cost of social...

The paper examines the ways in which recent economic growth has been uneven in China and India and what this has meant for inequality and poverty. Drawing on analyses based on existing household survey data and aggregate data from official sources, the authors show that growth has indeed been...

At the outset of China's reform period, the country had a far higher poverty rate than for Africa as a whole. Within five years that was no longer true. This paper tries to explain how China escaped from a situation in which extreme poverty persisted due to failed and unpopular policies. While...

Drawing on a compilation of data from household surveys representing 130 countries, many over a period of 25 years, this paper reviews the evidence on levels and recent trends in global poverty and income inequality. It documents the negative correlations between both poverty and inequality...

The paper presents the first major update of the international"$1 a day"poverty line, first proposed in 1990 for measuring absolute poverty by the standards of the world's poorest countries. In a new data set of national povertylines we find that a marked economic gradient only emerges when...

In 2005, China participated for the first time in the International Comparison Program (ICP), which collects primary data across countries on the prices for an internationally comparable list of goods and services. This paper examines the implications of the new Purchasing Power Parity (PPP)...

The authors provide new evidence on the extent to which absolute poverty has urbanized in the developing world, and the role that population urbanization has played in overall poverty reduction. They find that one-quarter of the world's consumption poor live in urban areas and that the...
