Richer India makes the world
poorer: Economist
Country’s Rapid Growth
Upsetting World Bank Estimates
New
Delhi: Angus Deaton, the Princeton economist regarded as world’s
foremost authority on cross-country income data, has cast
serious doubts on the World Bank’s last upward revision of
global poverty figures and India’s statistics are at the centre
of the storm.
The world became poorer as a result of a combination of
India’s economic growth and its low poverty line, Deaton, who is
president of the American Economic Association, said in his
presidential address to the AEA in Atlanta, in the US last
month. India’s extremely low poverty line was so strongly
depressing the average poverty line for poor countries that
India’s exit from this group because of its economic growth
resulted in the average rising.
The international poverty line is calculated by taking the
national poverty lines of a group of the poorest countries in
the world, converting them to US dollars by using a Purchasing
Power Parity (PPP) index, and taking a simple average. For its
latest 2008 revision, the bank for the first time changed the
set of poor countries used, since new data was available through
its International Comparison Program (ICP), and India was
dropped on account of its growth. The new poverty line was
updated from $1.08 per day at 1993 prices to $1.25 per day at
2005 prices. This raised the number of poor by 400 million to
1.4 billion.
Since India’s poverty line is low compared to its living
standards, as Indian average incomes rose and it moved out of
the group of selected countries, the global poverty line rose
and consequently so did the number of persons defined as poor,
Deaton showed.
“In effect, India and the world have become poorer because
India has become richer!” said Deaton in his address.
If Guinea-Bissau, which has a much smaller population but a
high poverty line relative to its living standards, were to get
richer and go past the cut-off line, the global poverty line
would decrease as would the number of poor. If poverty falls in
any country included in the counts, and increases nowhere else,
global poverty should fall. The current procedure does not
satisfy that basic requirement. Nor does it satisfy the property
that global poverty should fall by no more than the fall in
poverty in individual countries, Deaton observed.
An alternative procedure is to calculate the global poverty
line by averaging the poverty lines of all countries, but after
weighing them for the number of poor in each country. By this
method, the Indian poverty line would receive about a third of
the total weight, instead of being completely absent from the
current $1.25 per day poverty line. Another alternative Deaton
suggests is that the Indian poverty line be converted to dollars
and used as the global poverty line, provided that the line does
not shift if India gets richer.
Nobody ever said that India had to be in the reference group
of countries forever, countered Martin Ravallion, the director
of the development research group of the bank and one of three
authors on whose research the 2008 revision was based, in an
email to TOI.
The new sample of countries implies a higher international
line, but is more representative of the developing world,
Ravallion said. “As long as we agree on the principle that this
line should be representative of the lines found in low-income
countries, we must accept that poverty is higher than we thought
by those standards,” Ravallion reiterated in his email.
None of this necessarily means that poverty is improving in
India. Since Deaton and the bank are discussing global poverty
estimates, they do not get into the veracity of the Indian
poverty line.
In fact, both admit that global comparisons are mainly of
significance to international NGOs, while national policy is
based on country-level estimates prepared by national agencies.
At home, following a tortuous history of arguments over the
Indian poverty line, the Suresh Tendulkar committee in its
report to the Planning Commission two months ago suggested a
significant upward revision of India’s low poverty line from Rs
356.30 (rural) and Rs 538.60 (urban) per capita per month to Rs
446.68 (rural) and Rs 578.80 (urban) per capita per month for
2004-05. This is about $1.17 at 2005 PPP, closer to the World
Bank’s $1.25 figure. This implies that had India updated its
poverty line earlier, the global poverty line might have been
reset at $1.25 much earlier instead of being recently revised.
