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, though...

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...

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...

No one doubts the good data are essential to sound policymaking. Alas, data are invariably faulty. Methodological solutions to data inadequacies have often been proposed and implemented, but they have been tested only rarely. Yet the methods that are used may well determine the direction of...

With the limited set of policy instruments typically available in the rural sectors of developing countries, imperfect coverage of the poor and leakage to the nonpoor must be expected from even the most well-intentioned poverty alleviation scheme, One way to reach the poor more effectively is to...

Workfare programs aim to reduce poverty by providing low-wage work to those who need it. They are often turned to in a crisis. This article offers some simple analytical tools that can be used to rapidly appraise the cost-effectiveness of an existing workfare operation as a basis for deciding...

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...

Recent writings on poverty and hunger agree broadly on objectives and means but diverge significantly in emphasis. Views differ on the importance and function of economic growth and on how much weight to give to direct public support. These differences can matter in policy choices. "Hunger and...
