"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 presents a major overhaul to the World Bank's past estimates of global poverty, incorporating new and better data. Extreme poverty-as judged by what "poverty" means in the world's poorest countries-is found to be more pervasive than we thought. Yet the data also provide robust...

"Concerns about incentives and targeting naturally arise when cash transfers are used to fight poverty. The authors address these concerns in the context of China's Di Bao program, which uses means-tested transfers to try to assure that no registered urban resident has an income below a...

"The "developing world's middle class" is defined here as those who are not poor when judged by the median poverty line of developing countries, but are still poor by US standards. The "Western middle class" is defined as those who are not poor by US standards. Although barely 80 million people...

"It has been argued that inequality should be of little concern in poor countries on the grounds that (1) absolute poverty in terms of consumption (or income) is the overriding issue in poor countries, and (2) the only thing that really matters to reducing absolute income poverty is the rate of...

"Recent literature and new data help determine plausible bounds to some key demographic differences between the poor and non-poor in the developing world. The author estimates that selective mortality-whereby poorer people tend to have higher death rates-accounts for 10-30 percent of the...

"The idea that developing countries face a trade-off between poverty and inequality has had considerable influence on thinking about development policy. The experience of developing countries in the 1990s does not, however, reveal any sign of a systematic trade-off between measures of absolute...

"There has been much debate about how much poor people in developing countries gain from trade openness, as one aspect of 'globalization.' Ravallion views the issue through both 'macro' and 'micro' empirical lenses. The macro lens uses cross-country comparisons and aggregate time series data....
