MMM >> >We're making a differential
diagnosis of why countries get stuck with their bad economic performance.
We've looked at, how poverty traps can hold poor countries in
a grasp preventing them from making the basic investments to move forward.
We've looked at how physical
geography, the presence or lack of fossil fuels.
That the proximity to or distance to the coast.
The nature of the climate system.
Can shape economic development. Very often, people turn first to
culture as the explanation, of why some places are ahead, and others behind.
It's often
quite glib, because,rich people like to say, we're
rich because our culture is better, rather than to
say, we're rich because we have lots of
energy resources, good coastal proximity, and a healthy climate.
And rich people often like to blame poor people for
their problems, say, well, they're lazy, they're not working very hard.
And throughout history, places that were once
poor and they became rich were known quote
unquote as lazy places, during their period of poverty.
And then once they became rich, their culture
was used to explain their hard working ethos.
So culture can be a bit of an optical illusion.
A little bit to easy sometimes, as an attribution or a cause of a
countries conditions.
And we should remember that cultural phenomena, people's beliefs
and attitudes, their views towards appropriate roles in society.
Change over time as well.
SO culture isn't a fixed monolit. I believe culture has a
role, however, though not as big a role as sometimes thought.
And we
should focus on those atributtes of a societies
values, its norms, Its attitudes. As
ways that can be promotive or barriers
to sustainable development. I want to focus on three.
One is on demography and population. The second on education.
And the third, regarding gender.
When we look at the population challenge, a good place
to start is this world map of the fertility rate.
The total fertility rate in a country, and you'll recall Measures on
average the number of children that a woman will have during her lifetime.
It looks at the age-specific fertility rates for women in a society, and
then says, if women age 20 to 25 on average have this
many children, women age 25 to 30 have this many children, and so
forth, Then on average over the course of a woman's lifetime reproductive
years, an average woman in this society would have this number of children.
What the world map shows, is the tremendous variation in
our world today in the total fertility rate.
In many parts of the world, especially the
high-income world today, fertility rates are below two.
That means that each woman, on average, is having fewer than two children.
It means, since half the children are boys and half
the children are girls, On average, each woman is having
less than one daughter.
Or, if you say, 10 women, in total would be having fewer than 10 daughters.
You can see that when fertility rates are below two.
So, that, on average, each mother is not
replacing herself in the next generation with a daughter.
Statistically speaking that the population would tend to, be stable or declining.
When the total fertility rate is above two, then
the population would tend over the longer term to increase.
So, if in high-income world on this map we see total fertility rates below two.
We also see in some of the worlds poorest countries in notably in Africa and in
parts of South Asia, total fertility rates above four and many rural
areas in low income tropical Africa we have total fertility rates above six.
That is a pooe household would, on average,
the woman would be having six or more children.
This tremendously effects economic development because with very
large populations of young children, poor families Have
a very difficult time providing the basics for all of their children, maybe just
the eldest son is able to go to school and the girls are married at a young
age or working the fields about proper education and that means that in the next
generation those young girls will grow up without
the literacy and the skills that they need.
To help their own lives
their own children and the national economy to be productive.
So countries that had made, a transition from high fertility rate to
low fertility rates, have tended to have an advantage in economic development.
Countries that have still today very high fertility
rates tend to have much lower economic growth.
To a certain extent, this is a matter of income itself.
It's not really a matter of culture.
Poorer families, living on farms tend to have more kids.
And have less access to family planning to contraception, the girls don't have access
to schools and don't go to school and are married young and begin
having children at a very young age, but to some extent at least fertility
rates also reflect culture, lets look at one example of a society
that move rapidly, From high fertility rates to much lower fertiliity rates.
That's China.
They did that by and large through a
government policy known as the One Child Policy.
And while it's been very controversial, notice the implications of this policy.
What has happened, in a very
short period of time. Family size has come down rapidly and
parents have invested intensively in their one or
sometimes two children. And so that within one generation, the
levels of education, health, nutrition of Chinese young
population has soared. This played an enormous role in
China's very rapid economic development. So some places
by virture of culture, politics, of history, have still very
high fertility rates. Other places have made a rapid transition.
To lower fertility rates.
And the record shows very clearly
that those countries experience faster economic growth,
better health for the children, and higher educational attainments.
Over time this fertility rate shapes the population dynamics.
Whether the population is rising or declining in overall size,
and the age distribution of the population shown here by
the age population pyramid so called,
what these pyramids show, are the numbers of boys and girls
or men and women at various ages,uh showing the age structure of the
population If you look at Japan's population, for example, in 1950 when
fertility rates were still rather high, The number of children at the bottom
of the pyramid was much larger than the number of
their parents, and far larger than the number of the grandparents.
By 2005, the shape of that pyramid had changed considerably.
Japan had reduced its fertility rates.
Partly as a result of culture, partly as a result
of economic development, partly as a result of public policy.
And so now the number of children were actually fewer than the number of parents
because the fertility rate had come down below two.
And the whole age structure, therefore, wasn't a broad
pyramid with a big, big base of young children.
But was now much more similar in numbers of population at all ages.
By the middle of this century, because of the continuing low
fertility rate, the population age structure will be
an inverted pyramid. Few children, many more older people.
And that's how the transition occurs when fertility rates come down.
Most of today's very poor countries have that big base pyramid.
Huge numbers of very young children
to be supported. How are they going to be educated?
How are they going to get the healthcare and the nutrition that they need?
Only if today's high fertility countries are able, through matters of public
policy, cultural attitudes, and so forth to help reduce those fertility rates.
And the best way is through the voluntary choices
of, households who decide to reduce the number of children so that they can invest
more per child and help raise healthy and better educated children, unless
that happens, then the problems of
the large numbers of children outnumbering their
parents will continue to make very difficult
the economic development of the poor countries.
Another cultural
phenomenon involved attitudes towards education.
Some poor societies even in a state of great poverty, by tradition,
by culture, focused a huge amount of effort and attention on literacy.
Korea is one such country.
Korea even when it was impoverished in the middle
of the last century had a very high literacy
rate, and there was always great attention
in Korea's modern history to broad based literacy.
Well that's a cultural attitude as well as a government policy.
And it's done very well for Korea since the middle of the century and the terrible
Korean war that took place and devastated so much of Korea.
In South Korea,
we've seen some of the most successful economic development every attained, some
of the fastest economic growth And with a rather widespread prosperity.
A huge part of that has been facilitated by
this continuing commitment to broad based, high quality education.
And indeed this shows
up in international test scores. What you're looking at here are the
rankings on International testing, in science and math.
Where is Korea?
Right at the top.
It's not the richest country in the world, but it is right at the top ranks number
one or number two, definitely in almost every, test and
cateogry, within the top few countries in educational performance.
This reflects not only public investments in education, but it reflects
parental support for their children, urging their children to excellence.
It reflects a culture that has long strongly valued
education, and thereby made it possible for Korea to
become a world leader in technology. And one of the fastest growing countries
in the world. A third cultural attitude, that
deeply influences patterns of economic development, are attitudes towards women.
Do women have rights?
Are women participating in the labor force?
Do women face massive discrimination?
So, gender equality or inequality also has,
political aspects, but culture plays a significant role.
Once again, as with fertility and as with
education, there are big differences around the world.
In attitudes towards gender equality in attitudes towards women,
even in the physical safety of women from violence.
One can see the many, many ways that this influences economic development.
There's probably not a society in the world where
women still do not face at least some discrimination.
It took Tremendous political effort, social mobilization, and a lot of courage
of women to break through this
discrimination even in places today that we
view as close to gender equality if not fully there.
But there are many parts of the world
of course where women still face profound, profound barriers.
To their economic participation, to their
political particiiaption to hteir role in society.
What are the consequences of that? A society that tries to run on half
its brain power on half its human capabilities, block the role of women.
In problem solving, in economic leadership, in a political role.
A country that's running on only half its human resources is bound to fall behind
countries that are empowering all of their citizens, women and girls as well as
men and boys.
Countries where young girls may have one of two years of schooling, but then
because lack of interest, lack of budget, lack of family attention
and effort, are forced to drop out of school, marry young, start having children
young, do not have the productivity to participate in a modern economy.
Face a tremendous amount of poverty and suffering themselves.
And by dint of that are likely to be raising children in poverty as well.
Now, this is an area where there have
been huge changes, fortunately, in the right direction.
Over the last 30 years but by no means uniformed.
Look at this wonderful picture of the rowandan
parliament, it may surprise you to know that
rowanda's parliament is not only more than half women,
but has the highest porportion of women in it's
parliament in comparison with the rest of the world.
And women's participation in politics has soared in Rwanda and it
is rising in other parts of the world, though still with
the huge inequalities and still a tendency towards men dominating.
Political power.
In Rwanda you can see the wonderful
benefits of this turn towards women's empowerment.
And Rwanda has made astounding progress in reducing child mortality.
It's making big progress in improving education.
Social conditions have improved dramatically.
And while there are many factors that are contributing to Rwanda
escaping the poverty trap, the role of women in the parliament in my
opinion has played a significant role, Not only are, these women
powerful role models for young girls in Rwanda, and
I think Rwanda's success. In light of this experience
is a very powerful nessage for countries that are still lagging behind.
Don't try to develop with only half of your citizenry.
Take the lesson that a country that is mobilizing all
of its citizens, its girls, women, as well as its.
Boys and men, is a country that's going to have more success in the 21st century.
