Facts on world population
Total world population: 6.1 billion About 75% of people live in developing countries About 60% of the population lives in Asia and
Oceania About 40% of people live in only 15 countries By 2200, over 90% of population will live in what
today are developing countries

Population and economic growth
Reduction in birthrates can raise per-capita income in 2 ways
lower dependency ratio low consumption and high savings Shift of labor force investment from
capital widening to capital deepening

Different issues related to development Some important quality of life indicators
related to population growth– Improvement of levels of living – Increase in the labor forces– Higher population growth rates and poverty– Quality of health care and education – Relationship between poverty and family
size

The Demographic Transition
Stage I: high birthrates and death rates Stage II: continued high birthrates,
declining death rates Stage III: falling birthrates and death
rates, eventually stabilizing
![Page 16: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/16.jpg)
Dependency problems
Old age structures and young age structures both create problems with supporting dependents; they are just different problems.
Young age structure requires expanding labor markets, investments in education
Investments in older people less likely to enhance productivity
![Page 17: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/17.jpg)
The present demographic transition in developing countriesStage II already occurred in most of the
developing world,but with higher birthrates than in the developed world.
Stage III:– has been similar to developed countries for
some developing countries like Taiwan, South Korea, China,Chile, Costa Rica
– has not occurred yet for other countries mainly in Sub-Saharan Africa and the middle east.

Rapid and Slow Transition

Slow Transition Pakistan India Bangladesh Philippines Papua New Guinea

Miracles of rapid transition in East Asia Rapid demographic change creates windows
of opportunity for accelerated economic growth– Rapid growth of labor force– Saving and investment– Changing roles of women– Human resource investment

Stage of Demographic Transition and population requirement Population growth may be good at the
beginning In the middle factors like political
stability, cultural resources, and economic efficiency may be much more important than population growth
Reaching high income may require slowing growth
![Page 21: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/21.jpg)
Fertility and income
![Page 22: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/22.jpg)
Malthusian population model 1798
Population tends to grow at a geometric rate, doubling every 30 to 40 years
Food supplies only expand at an arithmetic rate due to diminishing returns to land (fixed factor)
Malthusian population trap: countries would be trapped in low per-capita incomes (per capita food), and population would stabilize at a subsistence level.– Preventive and positive checks
– Technological progress is not considered
![Page 23: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/23.jpg)
Household theory of fertility
Family size is a decision taken at the microeconomic level by households based on a rational economic decision on “demand for children”
Income effect: Higher income allows for larger family size
Substitution effect: Higher cost of children implies smaller family size
Other theories
![Page 24: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/24.jpg)
Why are there so many children in poor countries? Because children are an “investment” rather
than a “consumption good” the “expected return of theinvestment” is given by child labor and financial support for parents in old age
Parents have children up to the point at which their marginal economic benefit is equal to marginal cost
![Page 25: Aravinda Meera Guntupalli Population Growth and Economic Development.](https://reader036.fdocuments.us/reader036/viewer/2022081512/56649d895503460f94a6f29b/html5/thumbnails/25.jpg)
Hidden momentum of population growth It is the tendency of population growth to
continue, even after birthrates have decline substantially. – Substantial changes in birthrates may take
decades– when the young population is large, in the near
future high-fertility population will be high,even if fertility levels are lower.

Policy approach to deal with the high population growth
Decrease “marginal economic benefit of children”:
Increase the minimum-age child labor provide better old-age social security Increase “marginal cost of children” Increase education, employment and wages
for women

Policy approach
Better water and public health programs in rural and urban poor areas to lower infant mortality
Implementation of family-planning programs Improvement of quality of care of health and
family planning programs Monetary subsidies to small families Political commitment and role of religious leaders
