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...

While self-assessments of welfare have become popular for measuring poverty and estimating welfare effects, the methods can be deceptive given systematic heterogeneity in respondents'scales. Little is known about this problem. This study uses specially-designed surveys in three countries,...

Workfare schemes impose work requirements on beneficiaries. This has seemed an attractive idea for self-targeting transfers to poor people. This incentive argument does not imply, however, that workfare is more cost-effective against poverty than even poorly-targeted options, given hidden costs...

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...

Against what standards should we judge the developing world's overall performance against poverty going forward? The paper proposes two measures, each with both"optimistic"and"ambitious"targets for 2022, 10 years from the time of writing. The first measure is absolute consumption poverty, as...

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...

Development aid and policy discussions often assume that poorer countries have less internal capacity for redistribution in favor of their poorest citizens. The assumption is tested using data for 90 developing countries. The capacity for redistribution is measured by the marginal tax rate on...

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...
