Overview
____________
This report describes
world economic
growth, well being and interaction, specifically trends in GDP, poverty
and world trade. In brief, this report
shows that:
Economic Growth
- In the last several decades, total GDP
and GDP
per capita increased
in
OECD* countries, and in non OECD Eastern Europe and Asia. In contrast,
there has been little
overall growth
in Africa and the Middle East.
(*
OECD is the Organisation for Economic Co-operation and Development.
Basically OECD are the more advanced economies.)
Economic Structure
- Since 1970,
the
majority
of economic activity has been in the service
sector; 41%
in developing countries and 58%
in
developed countries.
- By 2001, 52%
of
economic activity among developing countries was in service, and 72% of
economic
activity among developed
countries.
- The pattern for industry is complex:
- Mainly decline
since 1980
in the developed world.
- Slight declines
in
the developing countries of Africa
and America, and recent
increases in Asia and Oceania.
- In 2001, Agriculture
was only 11% of economic activity in developing
countries, and only 2%
in developed countries.
- However, agriculture is a very large part of the labor force,
particularly in the developing
countries, where it accounted
for two thirds of the labor force in 1980 and
still over one half in 2001.
- Agriculture, as an economic activity and in the labor
force, is
particularly significant in Sub Saharan Africa
and Oceania.
- Agricultural productivity was very low in less developed
countries. This explains why a large part of the labor force was in
agriculture but only a small part of the GDP was in agriculture.
Poverty
- According to World Bank estimates, there has been an increase in the number
of people in poverty
in Europe, Central Asia, Latin America and Africa. In contrast,
East and South Asia has seen a decline
in the number of people
in
poverty (using $1 a day).
- The percent
of people in
poverty has also increased
in Europe, Central Asia, the Middle East and Africa, while the
percent in poverty declined
in
East and South Asia and Latin America.
- More recent data estimate that, in the last several years,
the percent of people in poverty has declined in Europe,
Central Asia, the Middle East and Africa.
- However, poverty is one of the most
difficult
indicators to
measure. Thus, there is no
universal
agreement on poverty definitions or trends. This
report will include an overview of the issues, in section III below.

Economic
Growth
GDP has some issues in measurement, which are briefly
described
in section IV, the data sources. However, the trends reported below
seem consistent
with many other trends in other areas (e.g., demographic, political,
technological). See our other reports for further details.

Poverty: Issues
____________________
There is considerable debate around global trends in poverty and
inequality (Ravallion,
2003). For example, there is disagreement about the amount of decline,
and a few argue that the data are insufficient
to determine whether poverty levels have changed (Reddy and Pogge,
2003).
As described above, according to World Bank
estimates, there
has been an increase in the number of people in
poverty
in Europe, Central Asia, Latin America and Africa. In contrast,
East and South Asia has seen a decline
in the number of people in poverty (using $1 a day). Also,the percent of people in
poverty has also increased
in Europe and Central Asia, and the Middle East and Africa, while the
percent in poverty declined
in
other areas.
On the other hand, Bhalla (2002) argues that there were large
declines in poverty rates, from 37% in
1985 to 13% in
2000.
Similarly, Sala-i-Martin (2002 a, b) estimates that poverty rates and
counts declined sharply over the last several decades. For example, the
one-dollar-a-day poverty rate declined from 20% in 1970 to 5%
in
1998 (Sala-i-Martin, 2002 a). Bhalla's and Sala-i-Martin's estimates of
recent poverty are much lower than the World Bank
estimate, of 23% in 1999.
Many researchers discuss the apparent contradictions in counting
world poverty rates and trends. For example, Ravallion
(2003) argues that the differences are due to measurement issues, e.g.,
how poverty is defined, use of absolute versus relative poverty, what
levels
are used to define poverty, using household or person as the unit of
measure and so forth. For example, poverty could be measured using a
relative poverty indicator, in which the 'standard' for poverty
increases as a country's income increases, or using an absolute poverty
indicator, such as "what poverty means in poor countries", or $1 a day
(Ravallion, 2003). Ravallion (2003) indicates that any measure is
somewhat arbitrary, but if the measure is used consistently, it can
still be used to measure change over time.
Ravallion (2003) also points
out that poverty data are often questionnaire based,
and there are a number of problems in using surveys. For example,
questionnaires
from different countries may use different definitions (e.g., using
income
versus consumption to measure well-being) or may ask about different
time
periods (e.g., last year, last month, etc). All of these variations may
result in finding different levels of poverty. Others may also use
national accounts to estimate poverty, but these also have problems,
for example from higher income people underreporting their income
(Ravallion, 2003). Bhalla (2002) compares estimates using survey data
and national accounts (table 9.1) and shows that the two methods give
similar estimates from 1950 to 1980 but substantial differents in 2000,
with national accounts showing much lower percents and counts.
Reddy and Pogge (2003) criticize the World Bank estimates, and
argue for a better measure. According to Reddy and Pogge (2003), the
main
problems with the World Bank estimates are, "The Bank uses an arbitrary
international poverty line unrelated to any clear conception of
poverty.
It employs a misleading and inaccurate measure of purchasing power
"equivalence"
that creates serious and irreparable difficulties for international and
inter-temporal comparisons of income poverty. It extrapolates
incorrectly
from limited data and thereby creates an appearance of precision that
masks
the high probable error of its estimates. The systematic distortion
introduced
by these three flaws may have led to an understatement of the extent of
global income poverty and to an incorrect inference that it has
declined"
(Reddy and Pogge, 2003, abstract).
In addition, others argue that poverty is a multi-dimensional issue,
beyond just income (Deaton, 2004; Kingdon and Knight,
2003; Mowafi, 2004; Rojas, 2005). For example, income does not account
for other
critical aspects of well being, such as fulfilment of basic needs,
social functioning, safety from insecurity (e.g., Kingdon and Knight,
2003), and lack of access to these basic necessities is seen by many as
a more important indicator of poverty than just income alone (Mowafi,
2004). In addition, people are more than consumers, so that exclusion
of these other aspects of life shows an incomplet picture of well being
(Rojas, 2005).
The issue of poverty measurement has not yet been solved, and
continues to be examined (see list of recent conferences).
In sum,
a decline in poverty
would be consistent with other changes among less developed countries,
such as improved literacy rates, declines in infant mortality rates,
increased
political freedom, increased newspapers, televisions and radios per
capita,
and increase in per capita GDP (Shackman, Liu and Wang, 2003). However,
that does not seem to be the pattern emerging, but rather there is
decline in some areas and increases in others. In addition,
there are a number of problems with data and methods, and
conclusions
are therefore our 'best guess', but not by any means certain.
For comprehensive
reviews of the issues involved with the meaning and
measuring of
poverty, see reviews by Deaton (2003, 2004) and Mowafi (2004).
More recently, a December 2006 issue of Poverty In Focus, by the
International Poverty Centre http://www.undp-povertycentre.org/PublicationShow.do
is "What is poverty, concepts and measures". This issue
describes similar issues, how to measure, what is poverty, and so on.

and his study, The
World
Economy: Historical Statistics (OECD Development Centre,
2003)
http://www.theworldeconomy.org/. Data since 1990 are from
Organisation for Economic Cooperation and Development (OECD), the U.S.
Bureau of the Census, the U.S. Bureau of Labor Statistics and specific
country data systems.
GDP
measurement
issues:
While GDP "is the best measure of aggregate economic activity that is
available" (Doepke, 2003, p5), there are some measurement problems
including:
- GDP only measures products and services that are bought or
sold,
so in some economies where things are bartered or traded with
neighbors, friends, relatives, etc, these things are not counted in GDP
(Doepke, 2003; Schenk, 2004).
- Official measures of GDP also often do not measure the
"underground economy", which is economic activity not reported to the
government (Braguinsky, 2005; Doepke, 2003; Schenk, 2004). For example,
people
working for cash who
don't report this income are part of the underground economy, but are
not counted in GDP.
- GDP also does not include leisure, housework, and child care
that aren't in the market system (Ireland, 2008).
- GDP does not account for changes in quality of products.
For
example when computers become more powerful, they are still counted as
the same product, even though they can do much more. Thus, economic
growth is often underestimated (Doepke, 2003).
- The underground economy could be as large as the
officially
measured economy in some countries (US Department of State, 2004)
Thus, GDP data should also be interpreted with some degree of caution.

Table 5.3 Agricultural
Production per Agricultural
Worker, 1980, 1990 and 2001
According to this report, "The aggregate “agricultural
production”,
expressed in international dollars, is the sum of crop and livestock
commodities after deduction of seed and feed utilization. Practically
all products are covered, with the exception of fodder crops.
Production quantities are valued by constant 1989-91 average
international commodity prices. This method assigns a single constant
price to each commodity regardless of the “Agricultural
worker” refers
to the estimates on agricultural labour force in 1980 and 1990 and the
projections for 2001."
Poverty
The poverty table presented above is from Table 1.6, in

Realizing the Development Promise of the Doha Agenda

A similar estimate also appears at this World Bank
site http://ddp-ext.worldbank.org/ext/GMIS/home.do?siteId=2
which says, "Per capita
consumption of $1 a
day
represents a minimum standard of living, .... In middle-income
economies a poverty line of $2 is closer
to the practical minimum."
