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...

Prevailing practices in evaluating workfare programs have ignored the disutility of the type of work done, with theoretically ambiguous implications for the impacts on poverty. In the case of India's National Rural Employment Guarantee Scheme, past assessments have relied solely on household...

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...

We are not seeing faster progress against poverty amongst the poorest developing countries. Yet this is implied by widely accepted"stylized facts"about the development process. The paper tries to explain what is missing from those stylized facts. Consistently with models of economic growth...

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 evidence...

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...

Two tradeoffs have been widely seen to severely constrain the scope for attacking poverty using redistributive transfers in poor countries: an equity-efficiency tradeoff and an insurance-efficiency tradeoff. The author provides a critical overview of recent theoretical and empirical work that...

The"stylized fact"that distribution must get worse with economic growth in poor countries before it can get better turns out not to be a fact at all. Growth's effects on inequality can go either way and are contingent on several other factors. The authors found no sign in the new cross-country...

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...

It is important to know how aggregate economic growth or contraction was distributed according to initial levels of living. In particular, to what extent can it be said that growth was"pro-poor?"There are problems with past methods of addressing this question, notably that the measures used are...
