We present new estimates of the extent of the developing world’s progress against poverty. By the frugal $1 per day standard, we find that there were 1.1 billion poor in 2001 — almost 400 million fewer than 20 years earlier. Over the same period, the number of poor declined by over 400 million in China, though half of this decline was in the first few years(More)
The growth incidence curve gives growth rates by quantiles ranked by income. Integrating this curve up to the headcount index of poverty gives a measure of the rate of “propoor growth” consistent with the Watts index for the level of poverty. Examples are given using survey data for China during the 1990s.
It has been claimed that in recent times the poor have There was no general tendency for inequality or lost ground, both relatively and absolutely, even as polarization to increase with growth. Distribution average standards of living were rising. Ravallion and improves as often as it worsens in growing economies, Chen test that claim, using more than 100(More)
China’s performance in economic growth and poverty reduction has been remarkable. There is an on-going debate about whether this growth is mainly driven by productivity or factor accumulation. Few studies however have incorporated annual data on China’s human capital stock, and thus contained an omission bias. In this paper, we construct a measure of(More)
In this paper, we investigate how reductions of barriers to migration affect the decision of middle school graduates to attend high school in rural China. Change in the cost of migration is identified using exogenous variation across counties in the timing of national identity card distribution, which make it easier for rural migrants to register as(More)
In this paper, the Type IV Pearson distribution is proposed to approximate the distribution of the sum of lognormal random variables, and the parameters of the Type IV Pearson distribution are derived through matching the mean, variance, skewness and kurtosis of the two distributions. Numerical simulations show that the Type IV Pearson distribution can(More)
We report new estimates of measures of absolute poverty for the developing world for the period 1981-2004. A clear trend decline in the percentage of people who are absolutely poor is evident, although with uneven progress across regions. We find more mixed success in reducing the total number of poor. Indeed, the developing world outside China has seen(More)
Panel data for rural China indicate that roughly half the in Rural China poverty is transient. This severely constrains efforts to Jyotsna jalan reach the chronically poor Martin Ravallion using cross-sectional data. But similar processes are at work in creating transient and chronic poverty. Summary findings Jalan and Ravallion study transient poverty in a(More)
