Do aggregate income shocks, such as those caused by macroeconomic crises or droughts, reduce child human capital? The answer to this question has important implications for public policy. If shocks reduce investments in children, they may have a long-lasting impact on poverty and its...

Widespread agreement that poverty is a multifaceted phenomenon encompassing deprivations in multiple dimensions clashes with the vociferous disagreement about how best to measure these deprivations. Drawing on the recent literature, this short paper reviews three methodological alternatives to...

Standard methods of impact evaluation often leave significant gaps between what we know about development effectiveness and what we want to know—gaps that stem from distortions in the market for knowledge. The author discusses how evaluations might better address these knowledge gaps and so be...

Policy-oriented discussions often assume that "better targeting" implies larger impacts on poverty or more cost-effective interventions for fighting poverty. The literature on the economics of targeting warns against that assumption, but evidence has been scarce and the lessons from the...

Brazil, China, and India have seen falling poverty in their reform periods, but to varying degrees and for different reasons. History left China with favorable initial conditions for rapid poverty reduction through market-led economic growth; at the outset of the reform process there were many...

Countries are increasingly being ranked by some new “mashup index of development,” defined as a composite index for which existing theory and practice provides little or no guidance for its design. Thus the index has an unusually large number of moving parts, which the producer is...

A new assessment is made of the developing world’s progress against poverty. By the frugal $1 a day standard there were 1.1 billion poor people in 2001—almost 400 million fewer than 20 years earlier. During that period the number of poor people declined by more than 400 million in China,...

Alternative scenarios are considered for reducing by one billion the number of people surviving on less than $1.25 a day. The low-case, “pessimistic” path to that goal envisages the developing world outside China returning to the slower pace of economic growth and poverty reduction of the...

This issue provides a usefully critical discussion of the current methods used by the World Bank for measuring poverty. The author will not address all the points raised by Deaton- avoiding those on which the author thinks there is broad agreement that the World Bank s current methods can be...
