"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...

Relative deprivation, shame and social exclusion can matter to the welfare of people everywhere. The authors argue that such social effects on welfare call for a reconsideration of how we assess global poverty, but they do not support standard measures of relative poverty. The paper argues...

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 paper revisits the site of a large, World Bank-financed, rural development program in China 10 years after it began and four years after disbursements ended. The program emphasized community participation in multi-sectoral interventions (including farming, animal husbandry, infrastructure...

Empirical studies of tax and benefit incidence routinely ignore behavioral responses and measurement errors. This paper offers an econometric method of estimating the mean benefit withdrawal rate (marginal tax rate) allowing for incentive effects, measurement errors, and correlated latent...

The paper presents the first major update of the international "USD 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 poverty lines we find that a marked economic gradient only emerges...

The authors report new estimates of measures of absolute poverty for the developing world over 1981-2004. A clear trend decline in the percentage of people who are absolutely poor is evident, although with uneven progress across regions. They find more mixed success in reducing the total number...
