Alternative scenarios are considered for reducing by one billion the number of people living below $1.25 a day. The low-case,"pessimistic,"path to that goal would see the developing world outside China returning to its slower pace of growth and poverty reduction of the 1980s and 1990s, though...

National poverty lines vary greatly across the world, from under $1 per person per day to over $40 (at 2005 purchasing power parity). What accounts for these huge differences, and can they be understood within a common global definition of poverty? For all except the poorest countries, 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 ample...

An assessment of the welfare gains from a targeted social program can be seriously biased unless it takes proper account of the endogeneity of program participation. Bias comes from two sources of placement endogeneity: the purposive targeting of the geographic areas to receive the program, and...

The authors assess the developing world's progress in reducing absolute-consumption poverty during 1981-91, using new data on the distribution of household consumption or income per capita for 40 countries (at two points in time for 18 of the countries). They apply dominance tests to the...

Comparisons of poverty - indicating where or when poverty is greatest, for example - typically matter far more to policy choices than aggregate poverty measures, such as how many people are deemed"poor."So the author's examine how measurement practices affect empirical poverty profiles. They...

In the wake of reforms to establish a free market in land-use rights, Vietnam is experiencing a pronounced rise in rural landlessness. To some observers this is a harmless by-product of a more efficient economy, while to others it signals the return of the pre-socialist class-structure, with the...

Economists often advise governments to target their spending better when cuts are called for. The author asks whether that advice is consistent with a political economy constraint that limits the welfare losses to the nonpoor from spending cuts. A simple theoretical model shows that the answer...

Although poverty lines are widely used as deflators for inter-group welfare comparisons, their internal consistency is rarely given close scrutiny. A priori considerations suggest that commonly used methods cannot be relied on to yield poverty lines that are consistent in terms of utility, or...

In counting the poor, and measuring the severity of absolute poverty, one faces a number of difficult questions. What poverty line should be used? Should one use the same poverty line across all countries? How should one adjust for differences across countries in the purchasing power of their...
