POPULATION AND DEVELOPMENT
What is the effect of population
growth on economic
development?
(pessimistic perspectives)
Kingsley Davis, A. Coale & Hoover, The World Bank
POPULATION AND DEVELOPMENT
 At the World conference on population at Bucharest in
1974 two schools of thought collided:

Neoclassic economists
In favor of slowing down population growth.
 Poverty is caused by Rapid Population Growth (RPG)


Marxist perspective
Demographic growth is independent from economic
development
 The causes of poverty are economic exploitation and political
domination

 Such debate takes place under the context of the Cold
War and an unprecedented demographic growth in third
world countries
Kingsley Davis (1908-1997)
 Reputed sociologist
 Helped to establish the
department of
demography of the
University of California at
Berkeley.
 President of the PAA
 Represented the USA
before the UNPC
Kingsley Davis (1908-1997)
 K. Davis popularized the terms:
 “population
explosion”
 “zero population growth”
 Stood against sending food to poor countries
because it would only make poor populations
larger in size and entirely dependent on charity for
their subsistence
 Argued that “excessive reproduction” (more than
four children per woman) should be consider “a
crime”
Kingsley Davis (1908-1997)
 Argued that rapid population growth (RPG) makes
economic development more difficult:





High dependency ratios cause by a large infant population
deters societies from investing its resources elsewhere
High fertility makes difficult for women to enter and stay in
the labor market
Parents of large families cannot provide their children with
adequate clothing, health care and proper education
RPG contributes to increase dramatically the number of
young people looking for a job, which leads to high youth
unemployment and ultimately to political unrest
Urbanization will be affected by massive migration from
rural areas of high fertility, creating a negative environment
for social stability and economic development
Kingsley Davis (1908-1997)
 Proposed several drastic measures to avoid RPG in
developing countries:
Increase the legal age of marriage
 Establish a tax for marriage and child bearing
 Mandatory sterilization after the 5th birth
 Pay money to those who sterilize voluntarily
 Governments should pay for abortions
 Reduce maternity aid

Ansley Coale (1917-2002) and Edgar M. Hoover
 Ansley Coale and Edgar M.
Hoover were co-authors of the
book:

Population Growth and Economic
Development in Low-Income
Countries (1958)
 Used data from India and
Mexico
 Provided the theoretical
foundations for birth control
policies in developing countries
financed by the U.S.
Government and the United
Nations
Ansley Coale (1917-2002) and Edgar M. Hoover
 Economic development requires investment of
capital.
 Capital is the wealth and the goods…


…used to produce more goods and increase the existing wealth
Not the wealth and goods used for immediate consumption!
 To escape poverty,
 growth rate of capital must be higher than demographic
growth rate
Ansley Coale (1917-2002) and Edgar M. Hoover
 Populations with high dependency ratios can devote
smaller amounts of capital to investment, which is
negative for economic development

The extraordinary increase of the number of children
makes saving more difficult for families and governments
Families must spend on food, clothing and school books
 Governments must spend resources on basics like health care and
education for larger number of children
 Governments have fewer resources to spend on infrastructures
such as irrigation systems, roads, energy plants, etc.


Otherwise, inadequate nourishment and health care
would cause the number and frequency of diseases
Ansley Coale (1917-2002) and Edgar M. Hoover
 Rapid Population Growth (RPG)…





Makes unemployment to raise and salaries to go down
Contributes to increase the prices of certain goods and
services
Makes Governments of developing nations more dependent
on foreign aid, which leads to increases on national debts,
thus widening the gap between developed and developing
societies
Worsens the economic situation of poor people
Increases the probability of social unrest and revolts
Ansley Coale (1917-2002) and Edgar M. Hoover
 When populations grow faster than capital
accumulation (investment) they will find
themselves trapped inside a Malthusian vicious
circle of poverty:

Economic growth will make possible to feed more mouths,
but not suffice to escape from poverty and misery
 To escape poverty, capital accumulation must grow
faster than population
The World Bank
 The World Bank published in 1984 a study in which it is
argued that RPG slows down economic growth:





Diverts resources into consumption rather than into more
productive investment
It complicates making the necessary investments to improve “the
quality of the population”
Threatens the precarious equilibrium between population and
natural resources
Makes more difficult the adjustments and transformations that
must accompany social and economic changes

86/5967/WDR%201984%20-%20English.pdf?sequence=1
 Page 106 of the report states that:
 “Experience has shown that as development progresses
fertility falls. Yet, because current rates of population growth
are so much greater in the developing world than they were at
comparable income levels in today's developed countries,
many developing countries cannot afford to wait for fertility to
decline spontaneously.”
The World Bank
 The world Bank also acknowledges that under certain
circumstances a moderate population growth can indeed
be beneficial for development



It stimulates demand, technological innovation and reduces
investment risks
A moderate increase on the size of working population along with
adequate investments on education can improve the productivity
of the working population
In countries where population is very sparsely distributed,
demographic growth (higher population density) may be
beneficial because it makes infrastructure investment more
feasible and less risky
The World Bank
 The world Bank study acknowledges that
 Demographic growth is not the major cause of poverty
in Third World countries
 Many countries have managed to increase their income
per capita even under RPG
 However, The World Bank recommends that
Governments in developing countries should
indeed implement policies for population control
to slow down demographic growth


American biologist and
Professor at Stanford
University
The Population Explosion
(1990)
Paul y Anne Ehrlich
 In the book “The Population Bomb” (1968), Paul R. Ehrlich
affirmed that:





The battle to feed all humans is lost: During the 80’s and 90’s
hundreds of thousands will starve to death
Aid programs will be useful only to delay the catastrophe
Human population is spreading all over the planet like a cancer
Technological improvements may increase food production for some
time but at the price of spoiling the environment
The problem can only be solved by decisive policies of population
control
 Changing values to ensure voluntary self-control
 Tax all products related to child rearing
 Reward those who agree to sterilize before having a second child
 Coercive measures are also legitimate
Paul y Anne Ehrlich
 In the book “The demographic explosion” (1990) ,
Anne Ehrlich considers that the most important
challenges humanity faces are:
The rapid depletion of the nonrenewable resources of the
planet
 The global deterioration of the environment, which will
provoke shortages on drinking water supplies
 Risk of wars for the access to increasingly scarce
resources
 There is a need to convince reluctant politicians that
classic economy must be replaced by “eco-economy”

Lester Russell Brown (1934-)
 American, MS in
Agricultural economy
 Developed the concepts


Eco-economy
Natural Capital
 In 1974, along with the
Rockefeller Foundation
he created the World
Watch Institute

http://www.worldwatch.org/
Lester Russell Brown (1934-)
 Free market economy is more efficient than centrally
planned economy but it does not account fully for all
the costs of producing the goods we want because the
consequences of environmental degradation are not
contemplated
 The eco-economy considers fertile lands, forest, fishing
banks, etc., as if they were Natural Capital
 Therefore, degradation for the environment should be
regarded as a decapitalization problem, thus,
impoverishment
Lester Russell Brown (1934-)
 Lester R. Brown considers that population growth represents
a serious problem because it provokes







Deforestation of the planet
Depletion of fishing banks
Rising levels of carbon dioxide
Erosion of the soil
Scarcity of drinking water
Raise of temperatures
Extinction of species
 He supports the diffusion of population control programs


Sterilization
Family planning
 He supports the one-child policy of the Chinese government
Eric R. Pianka (1939-)
 American biologist
 Professor of Zoology at
Texas University
 The American Academy
of Sciences named him
“Scientist of the year” in
2006
 The Book of Life
 Evolutionary Ecology
(1983)
Eric R. Pianka (1939-)
 Humans are destroying “The Book of Life”
 Humans are destroying the ecological niches and
environments even before we had the chance to study them
fully
 Denounces our economic model as anthropocentric and
proclaims the value of biodiversity
 Affirmed that population growth is disastrous for life on
Earth because of the pollution we cause

“Every time you breath, take a shower or pull the flush, every time
you drive your car or buy anything, you are contributing to spoil and
contaminate the planet”
 He supports policies for population control and estimates
that up to 90% of human population should be reduced to
reach tolerable figures for the planet
James E. Lovelock (1919-)
 English scientist
 Works for NASA
 Earth, Gaia, is a living
organism
 All living creatures and
also nonliving things are
part of that organism
 “On aggregate, human
beings have grown enough
in numbers to be regarded
as a serious planetary
disease”
 “Gaia suffers Primatemia
diseminada, a plague of
people”
Garrett J. Hardin (1915-2003)
 American biologist
 Professor of Human
Ecology at California
University (Santa
Bárbara)
 Author of


The tragedy of the
commons (1968)
Living within limits
(1993)  lifeboat theory
Garrett J. Hardin (1915-2003)
 In economics, Adam Smith, developed the concept of the
“invisible hand”, the idea that when individuals seek their
own self-interest, the general interest is also attained
 In “The tragedy of the commons” (1968), Hardin explains
how a village of cattle owners would function if property of
the cattle is private but pastures are of common property
and its grass is shared by all the community
 Free access to resources brings about the ruin for
everybody
Garrett J. Hardin (1915-2003)
 In “The tragedy of the commons” (1968), Hardin
supports the idea that humans live in a finite world
which can give support only to a limited number of
people
 Is it correct to let people decide freely about the
number of children they may have?
 Regarding human reproduction, the “invisible
hand” does not work in favor of the common good
Garrett J. Hardin (1915-2003)
 Exploring new ethics for survival:
 living in a lifeboat (1974)
 lifeboat ethics (1974)
Hardin critisizes sending food and medicines to the third
world countries
 It makes their populations continue growing and
therefore violating what he considers the first
commandment of modern Ecology:


“one shall not exceed the carrying capacity”.

Each country should bear the burdens of their own
reproductive behavior

Hardin estimated the optimal size for human populations on
100 million people
Garrett J. Hardin (1915-2003)
 In “Living within the limits” (1993), Hardin
advocates again in favor of his “lifeboat theory”:
Planet Earth is like a spaceship or a lifeboat which carries
a limited amount of supplies
 Inside this boat, humans are to be regarded as a burden
who are exhausting the supplies
 Harding does not pay consideration to the fact that
humans, thanks to our technology, may indeed be
capable of generating new resources or “expand” the size
of the boat

Garrett J. Hardin (1915-2003)
 Hardin considers people should not be free to decide
how many children to have…
 … if parents were the only responsible for the
consequences…
 However, nowadays, many societies are engaged on
attaining goals like a proper Welfare State, where
many costs of having children are transferred from
families to the State
Garrett J. Hardin (1915-2003)
 Hardin supported drastic measures to reduce
population growth:




Limit the number of children a couple may have
Sponsor abortion
Euthanasia to newborns with severe physical problems
Justifies infanticide within its proper historical context
 He even developed ideas close to Eugenics and Social
Darwinism:

People who go to university is more intelligent. It would be
better to have them having children and not the less clever
ones
Garrett J. Hardin (1915-2003)
 Hardin didn’t realize that what was happening was
something quite different than what he was fearing:
 Close to half the population hardly reaches
generational replacement.
 Couples have fewer children because most of the costs
will have to be born by themselves with little help from
governments
 However, the future benefits of a child, after becoming
an adult, will be profited by the whole society

Amongst its tasks there was the coordination of efforts to slow down
population growth
It backed China’s one child policy and sponsored Vietnam’s 2 child
only policy
Gets funding from various private foundations which are in favor of
slowing down demographic growth
 UNICEF http://www.unicef.org/

On 1966 there was a big conflict between members of the directive
board who disagreed on weather this organization should sponsor or
not policies for population control
 UNESCO http://en.unesco.org/
 Its first director was Julian Sorell Huxley, a member of the British
Eugenics Society, who favored policies for population control
POPULATION CONTROL AND POLITICS
 Julian Sorell Huxley:



"…unless [civilised societies] invent and enforce adequate measures
for regulating human reproduction, for controlling the quantity of
population, and at least preventing the deterioration of quality of
racial stock, they are doomed to decay…“ (Huxley, Julian. 1926.
Essays in Popular Science. London: Chatto & Windus, ix.)
Opposed Catholic and Communist views on population control
In “The Crowded World” he predicted 6 billion people for 2.000 and
warned consequences could be catastrophic
POPULATION CONTROL AND POLITICS
 The World Bank


On numerous occasions the help provided by this institution
was given under the condition that receiving governments
should implement policies of population control
Several of its presidents had quite strong views on this matter
Robert McNamara: Rapid population growth is a major obstacle
for economic growth and for wellbeing amongst members […]
Demographic control is an area where The World Bank must take
initiatives
 Alden Clausen: Some countries will not be able to develop if they
do not stop soon their demographic growth
 Baber Conable: It is imperative that developing countries renew
their efforts to stop demographic growth

POPULATION CONTROL AND POLITICS
 The U.S. Government



President Eisenhower appointed an expert group chaired by David Rockefeller to
evaluate the prospects for the expansion of American Industry (1952):
 RPG could be a threat for American interests because deprives America from the
access to necessary resources and increases the chances of revolutions
President Nixon appointed Henry Kissinger, chair of the NSA, to create a report on
how population growth could affect American interests (1970):
 The “Kissinger Report” alerted about massive migration to cities and developed
countries and increasing social unrest which may turn into support of
revolutionary movements
 A more populated third world may limit the access of America to its resources
 Favored the implementation of policies for population control (“family planning”)
International Aid Act (1978)
 International aid should go to nations that agree on implementing policies for
population control
President Ronald Reagan

Influenced by the work of Julian Simon, he changed the American policy on population control
POPULATION CONTROL AND POLITICS
 Numerous foundations and private organizations active in favor
of population control are funded by very rich and influential people


Ford, Rockefeller, Airlie, Kellog, General Service, Andrew Mellon, Sunnen,
Tinker, John D. y Catherine T. MacArthur, Public Welfare, William y Flora
Hewlett, David y Lucile Packard, Bergstrom, Bill y Melinda Gates…

POPULATION CONTROL AND POLITICS
 The demographer Susan C. Watkins
pointed out that many scientific articles
published on the journal “Demography”
during the second half of the 1960’s are
“obsessively” oriented to assert the idea
that is was imperative to slow population
growth in the third world
EUGENICS
 Francis Galton (1822-1911) founding father of eugenics
 Eugenic selection vs natural selection
What mother nature does blindly, humans can do
consciously
 Positive eugenics
 Preserve genetic legacy of superior individuals
 Ban mixed marriages
 Stimulate their reproduction
 Negative eugenics
 Prevent inferior individuals from reproducing
 Prevent migration
 Sterilization

Couples should need maternity permit from governments
Permits will be granted if couples have adequate economic resources and had no
hereditary diseases
No permits should be issued to have more than one child
The retarded, criminals and those having had hereditary diseases should be
sterilized
 Eugenics in Europe


Germany: during the 1930’s about 320.000 people were sterilized
Between 1934 and 1975 up to 63.000 and 48.000 people were sterilized in
Sweden and Norway (mostly women)
POLICIES ON BIRTH CONTROL
 India



Since 1959 compensations are offered to those who agree to be sterilized
In 1975, the Indira Gandhi Government decreed a temporary “emergency”
suspension of certain civil rights to force more sterilizations including
measures such as:
 Obligatory sterilization of couples with at least 4 children
 A certificate of sterilization is required for certain government permits,
credits or subsides to buy fertilizers for the land
 Schooling for children whose parents have more than 3 children is denied
 Housing provisions were approved for those who accept being sterilized
 Illiterate people were sterilized without knowing about it after visiting the
local HMO
Because of these aggressive policies, increasing numbers of Indians stopped
going to clinics and health care centers. Finally, due to numerous revolts
against birth control policies, the government fell in 1977
POLICIES ON BIRTH CONTROL
 India





The new government continued sponsoring birth control policies but restricting them
to women who voluntarily accept it
Individual incentives for doctors who convince people to be sterilized
Collective incentives to convince communities (villages) to accept sterilization in
exchange for some public works
Extensive use of not entirely safe methods of sterilization (mainly on women) such as:
 Net-En,
 Norplant (58% of women suffered severe secondary effects: thrombosis, hepatitis,
arthritis and in some regions implanted only on Muslim women)
 Quinacrine, declared illegal by WHO
All these policies had the support of international institutions
 The World Bank financed the Norplant campaign
 The IFFH (International Federation of Family Health) financed the Quinacrine
 The IPPF (International Planned Parenthood Federation)
 Western Governments required as a condition for sending food aid the
implementation of birth control policies
POLICIES ON BIRTH CONTROL
 Bangladesh:
Norplant implanted on women in exchange for cereals and a dress
 Vietnam: The Two Child Policy
 Parents who have more than 2 children:
 Are obliged to pay for health care and education of the 3rd child
 Are expulsed from the Communist Party
 May have their land confiscated or obliged to abort
 Philippines: The 1995 (Bh-GC) hormone scandal
 The Supreme Court, declared proved that this vaccine against tetanus
contained one hormone that caused abortions and sterilization
 The campaign was sponsored by UNICEF and denounced by the Philippine
League of Catholic Women
 Further investigation proved that the vaccination campaign had already
reached 3 million women in the Philippines and had also been administrated
in at least other 4 countries

POLICIES ON BIRTH CONTROL
 Peru
In 1995 the Fujimmori Government developed a campaign for sterilization
partly funded by USAID and UNFPA
 In 2002, after leaving power, it was known that 90% of people sterilized
were not told about the irreversibility of the operation
 Puerto Rico
 Sterilization of one third of fertile women thanks to the support of the IPPF.
 Most women did not know the operation was irreversible
 Colombia
 Sterilization of women thanks to the support of the IPPF.
 Most women did not know the operation was irreversible
 Mexico
 Indigenous communities accept sterilization in exchange for public works,
housing, clothing, or health care centers
 Promised were not always kept

POLICIES ON BIRTH CONTROL
 China: The One Child Policy
 After the 1949 revolution Mao Zhedong opposed population
control policies: “Of all things of this world, people are the
most valuable […] Under the leadership of the Communist
Party, any miracle can become real”
 In 1953, Party officials were alarmed because of the difficulties
to feed all the population
 In 1956, a year of bad crops, Mao urged officials from highly
dense populated areas to develop policies for birth control
 The idea that fertility is not to be regarded as something that
should be kept on the private domain but rather as a matter of
concern for the State began to take shape
 In 1979 the “one child policy” was adopted
POLICIES ON BIRTH CONTROL
POLICIES ON BIRTH CONTROL
 China: legal reforms favoring birth control
 Chinese Constitution: All married couples are obliged to abide
to birth control policies
 It is illegal to have children if the woman is not married
 Legal age of marriage is established at 22 for men and 20 for
women
 Obligatory sterilization for couples who at the moment had
had already two or more children
 Women who had already one child should implant a IUD
 Couples with a record of any hereditary disease are forbidden
to have children
 Civil servants are to conduct regular pregnancy tests on all
married women

Expulsion from the Communist Party
Administrative sanctions, fines
Single mothers must pay fines up to ten times the salary of one
year
Those who can’t pay the fines will have their properties
confiscated (land, cattle, flat…)
Forced abortions and sterilizations
POLICIES ON BIRTH CONTROL
 Some international organizations have denounced such practices
Human Rights Watch
 International Amnesty
 Freedom House
 The Chinese Government has always stick firmly to the idea that:

caused by the demographic explosion” Economic Daily January 24th
1989, quoting a senior government official from the Ministry of
Agriculture

UNINTENDED CONSEQUENCES
OF BIRTH CONTROL POLICIES
 Patriarchal values…
 Traditional preference for a male son, particularly in Asia
 In India it is the son the responsible for lighting the funerary
pile of the parents and pray for their souls
 In societies were women are discriminated, sons are more
likely to reach a position (income level, land property) from
which they can help their parents during old age
 The dowry can be a burden for low-income families
 In certain cultures, the daughter is considered as member of
the husband’s family after marriage
 …and aggressive birth control policies may lead to
female infanticide and feticide
UNINTENDED CONSEQUENCES
OF BIRTH CONTROL POLICIES
 A biologically normal
sex ratio is one of 105
to 107 men per 100
women at birth
 Higher values indicate a
bias against women

doctors to know the sex of the baby after six months of pregnancy
This “service” is being widely used as a mean to prevent a baby girl
from being born in many countries
One study conducted in Bombay in 1984 showed that out of 8.000
abortions, 7.999 were of baby girls

POPULATION AND DEVELOPMENT
What is the effect of population
growth on economic
development?
(optimistic perspectives)
Simon Kuznets, Ester Boserup, The French School of Demography, The
Chicago School of Economics, F. von Hayek
Simon Kuznets (1901-1985)
 Born in Pinsk (Belarus)
 Studied in Kharkiv
(Ukraine)
 In 1922 migrated to the US
and got a PhD at Columbia
University in 1926
 Nobel Prize in Economics in
1971
Simon Kuznets (1901-1985)
 Kuznets analyzed statistical data from second half of
the 18th century until the turn of the 20th century
 He reached the conclusion that there was not a single
case where an increase on population growth had led
to a decrease on income per capita
 Kuznets found demographic growth to be associated
with economic development
Simon Kuznets (1901-1985)
 I) Demographic growth is caused by sustained drop
of mortality (notably infant mortality)



This reduces the efforts and resources wasted on rearing
children who will not make it to adulthood
It freed women from childbearing and rearing tasks,
allowing them to participate more actively on the labor
market
Morbidity rates also decreased and life expectancy
increased, which contributed to make individuals more
productive over their lifetime
Simon Kuznets (1901-1985)
 II) Income per capita is higher in growing populations
 Growing populations can spread over formerly inhabited areas
and exploit its resources (Russia, America)
 Growing populations are more mobile than stationary populations,
which makes the economy more dynamic
 Growing populations develop a more intense division of labor
 Young people tend to be more receptive to the consumption of
new products and services
 Young people have a stronger tendency to search for jobs in
newly developed occupational niches
 The larger the proportion of young people in the society, the
faster those new economic niches and sectors will develop
 Younger cohorts of workers tend to be more productive
 Internal markets/demand develop faster allowing business to
benefit from “economies of scale”
Simon Kuznets (1901-1985)
 III) The most important factor for increasing
production (income) per capita is knowledge, applied
knowledge, useful practical knowledge which is
developed by scientists, inventors, engineers and
entrepreneurs


Everything else equal, in growing populations there will be
more geniuses and scientists and other talented people
Creativity flourishes in intellectually dense atmospheres
Simon Kuznets (1901-1985)
 IV) Demographic growth stimulates savings and capital
accumulation (contrary to Coale and Hoover’s belief!)


a) Children are an incentive for hard work and saving
 Savings accumulated by a household with many children do
NOT need to be smaller than those generated by a small
household. A couple with fewer children may simply spend
more on other commodities
b) Aggregate savings tend to be higher in growing
populations
 A growing working population will generate larger amounts of
aggregate savings and the ratio of working people to pensioners
will be higher
Simon Kuznets (1901-1985)
 Societies open to immigration often…


…have faith on future
…trust they can integrate migrants into the labor market
 Having children is also a sign of confidence and optimism
 A society with a stagnant population reveals lack of optimism
and faith on a prosperous future
 There is no reason to believe that a larger population will not
be capable of attaining what smaller populations achieved in
the past
 Populations may grow and increase production (income) not
only to satisfy the needs of population surpluses but also may
increase production (income) per capita
 Uwaga!: Populations may grow even if birth rates decrease!
Ester Boserup (1910-1999)
 Born in Copenhagen
 Expert on agricultural
economy
 Studies the varieties of
agricultural production
in developing societies
 Refutes Malthus thesis
Ester Boserup (1910-1999)
 Author of 3 fundamental works:
 The Conditions of Agricultural Growth: The
Economics of Agrarian Change under Population
Pressure (1965)
 Women's Role in Economic Development (1970, 1997)
 Population and Technological Change: A Study of
Long-Term Trends (1981)
Ester Boserup (1910-1999)
 The Conditions of Agricultural Growth: The
Economics of Agrarian Change under Population
Pressure (1965):



Agricultural production does NOT set the limits for
population growth
Agricultural production is the result of innovations
triggered by population pressure
Demographic growth forces farmers to:
 Abandon
traditional forms of agriculture (extensive and low
productive)
 Adopt new more intensive and productive techniques
 Ancient Rome 10.000m2 of farm land per person-year
 Nowadays  1.000m2
Ester Boserup (1910-1999)
 The Conditions of Agricultural Growth: The
Economics of Agrarian Change under Population
Pressure (1965):



Higher population density favors deeper division of labor
and allow financing collective works and investments that
otherwise would be unprofitable (irrigation, transport)
Better infrastructure (thanks to larger population) makes
the use of newer technologies more feasible
Historically, a major factor against population growth in
developing nations had been the colonial agricultural
system imposed by the Europeans to native populations

Ester Boserup (1910-1999)
 Population and Technological Change: A Study of
Long-Term Trends (1981)




Some technological improvements were found by chance but most
are due to years (if not centuries) of research and experience
Demographic pressure had a major impact on discovery and
transmission of technological improvements
“Necessity is the mother of innovation”
Many societies did not develop because of lack of motivation
 Regulated population growth instead of developing innovations
 Population density remained low
 Continued using primitive techniques
Ester Boserup (1910-1999)
 Women's Role in Economic Development (1970)




Population growth is more problematic when half of the
society is marginalized to a subordinate position
Societies were women’s talent is exploited are more likely to
produce more technological advances and innovations
Participation of women on decision making processes have
extremely positive effects on agricultural production

 Alfred Sauvy (1898-1990):

Author of a study on the budget of the French
Government in 1939 which supported Landry’s thesis
regarding the financing of basic infrastructures:
Only 20% of expenditures vary according to population
 The remaining 80% were fixed expenditures
 More population means more taxpayers to share the burdens
derived from the maintenance of basic infrastructures (fixed costs)


Delegate of the French Government at the first UN
sponsored World Conference on Population (Rome 1954)
France pioneered the demographic transition (lowering of
mortality and fertility rates) but its industrialization was slower
than that of other nations like Britain and Germany
 The cause may have been the lack of demographic pressure
 Reduction of fertility and population growth are NOT the key
elements to economic and industrial development!

The French School of Demography
 Alfred Sauvy (1898-1990):
 Author of “Croissance zéro?” (1973)
It is imperative not to confuse overpopulation with
underdevelopment: the existence of many poor does not mean
there is too many people
 A growing population has better chances of development than a
stagnant population (thanks to generational replacement process)
 An abrupt reduction on fertility may have negative consequences:




Fast demographic ageing
Larger fractions of old people may lead to “decadent conservatism”
The ideal context is that of a moderate growth


Historically, periods of major social an economic development have
coincide with remarkable increases on population
Demographic downsizing has never brought positive rewards
The French School of Demography
 Alfred Sauvy (1898-1990):
 Mathematical models emphasize the relative advantages of
population decrease but do not take into consideration the
“human factor”, the human reaction in face of adversity
 The contribution of a person during the adult life to the
general wealth is much greater that what is consumed during
childhood or old age
 It is a mistake to think that reducing the number of people
contributes to reduce poverty
 Fewer births today means fewer researchers and
entrepreneurs tomorrow
 Fewer births today mean smaller young cohorts tomorrow

Between 1950 and 1980 the exceptional demographic growth
in the third world has come along by an even stronger
economic growth
 Population growth rate: 2.5 yearly
 Economic growth rate: 5% yearly
Cases where and when poverty increased are not caused by
population growth but by wars corruption and blatant misuse
of public funds
Demographic growth stimulates investment on infrastructures,
sustainable only under a certain population density and
expands internal markets
Increased life expectancy increases propensity to save money
Economic and demographic growth are consequences of the
same modernization process (technical and institutional)

of Alfred Sauvy
 Developer of the concept
“Demographic Winter”
The French School of Demography
 Gérard-François Dumont (1948-)
 Famines and poverty are not caused by overpopulation
but by wars, corruption and misguided policies
 Demographic winter is the persistent reduction of
fertility levels below replacement rates which is taking
place in many OECD countries
 Migratory flows are not sufficient to compensate the loss
of the “unborn population”

The Chicago School of Economics
 Theodore William Schultz
 Gary Stanley Becker
The Chicago School of Economics
 One of the most reputed school of economics in the
United States
 Up to nine Nobel Prize laureates have develop their
careers at its Department
 Theodore W. Schultz (1902-1998)

Nobel Prize in 1979
 Gary S. Becker (1930-)
 Nobel Prize in 1992
The Chicago School of Economics
 The Chicago School of Economics pioneered the
development of the concept of human capital
 Resources devoted to health care and education should
not be regarded as expenditures but as investments
 Investment on human capital is indeed more crucial for
economic development than mere accumulation of
physical capital because…
 Helps technological innovation
 Increases worker’s productivity
 Prevents from falling into the traps of “diminishing
returns” and the “dissolution of physical capital”
The Chicago School of Economics
 However, Becker warns that human capital development
is not enough. It is equally important to develop adequate
institutional arrangements:


Free market, flexible price system
Freedom to choose one’s education and occupation
 The best instrument the UN has to offer to developing
economies are wise economic advise (not expensive and
useless birth control policies)
 The “population bomb” will be effectively defused by
promoting free market and investment on education
 Economic development and female access to education
and the labor market are, indeed, the most effective
contraceptives

 In The fatal conceit: The errors of socialism (1988)
Hayek devoted one chapter to demographic growth





Malthusianism is obsolete
Demographic growth favors diversification and
specialization of human activities
A larger population is also a more diverse society
Demographic growth is a condition for progress
The survival of our civilization depends on capitalism and
demographic growth
If population was reduced to …. It would be impossible to sustain
our current technological development even if knowledge was
available in libraries (lack of human resources to implement them)
 Only the capitalist system can attain the production levels that are
required to satisfy the demands of the world’s current population

Poverty and Famines: An Essay
on Entitlement and Deprivation
(1981)
Amartya K. Sen (1933-)
 The demographic transition that lasted two centuries in Europe may be
shorter in developing nations if the adequate policies are implemented
 Favors investments on health care and education
 Economic development (and reduction of mortality) will slow
down “naturally” the population growth
 With few resources major achievements can be accomplished: like
improving female education
 Not necessary to reach the same level of income per capita as in
Europe to start lowering fertility rates
 There was big variation within Europe itself on income per capita
when birth rates declined
 Opposes birth control policies
 Limits individual freedom and leads to infanticide and feticide
 More Than 100 Million Women Are Missing
 Developing populations need more freedom, not less
Amartya K. Sen (1933-)
 Favors slowing down rapid population growth (RPG) in
developing countries



Limit growth of overcrowded cities in developing countries
Reduce pressure on the environment
Free women to get higher education and participation in the labor
market
 Disagrees with Neo-Malthusian perspective
 Food production has increased at higher rates than population
growth, most particularly in the more populated countries
 Famines are caused by reasons other than population growth
 Dictatorships, Corruption, Wars and Colonial occupation
 The best instrument against famines is democracy and free press
 Protect the right of the poor to access the food market
 Avoid political instability (panic buying) and overpricing of food
(urban development may harm rural communities)

 Considers that a serious cost-benefit analysis is needed:
 There are better ways to fight Global Warming than
implementing the Kioto protocol
 Lomborg discards that temperatures will rise as much as
forecasted by models based on man-made global
warming theories over the next century
 He suggests to invest resources on technological
development for the long term rather than spending
money trying to fix in a decade what is already
unavoidable but not so dramatic (man-made global
