Our first topic—Topic 9—is on sustainability.
What is “sustainable development”?
8
![Page 9: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/9.jpg)
Following the 1983 UN Brundtland Commission, we’ll
view sustainability quite broadly…
“sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet
their own needs.” 9
![Page 10: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/10.jpg)
Up to this point, we’ve only been considering the rights &
interests of actors in the present.
Taking sustainability seriously means including the rights and interests of future generations.
10
![Page 11: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/11.jpg)
That makes some sense: who would suggest it were responsible
to leave a wasteland for our grandchildren?
But surely we must apply some kind of discount rate to these
considerations.
As we look further into the future, it becomes more likely that some
unavoidable calamity—e.g. a meteorite—would wipe us all out
anyway.11
![Page 12: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/12.jpg)
Also, how can we know where to invest our resources?
Should we let SETI use our computers at night? Or Folding
at Home? Or perhaps we should turn them off entirely to
preserve the environment?
12
![Page 13: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/13.jpg)
Here’s the key starting point:
We know that we should include the interests of future generations in our present calculations, but it can be rather difficult to do this.
Even assuming altruism, there are significant limits to our capacity to
accurately predict the consequences of our actions.

Three Facets of Sustainability
• Population Growth (Today)• Our Environment (Thursday)• Our Financial Legacy (Next Tuesday)
15
![Page 16: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/16.jpg)
Population Growth & Sustainability
• Key issue: how does our rate of increase affect the sustainability of our development?
• Directly affects the present-versus-future calculation– Reproductive rights here and now– Circumstances of our progeny in the
future
• Apparent correlation between population growth rates and development
16
![Page 17: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/17.jpg)
Our Environment & Sustainability
• Key Issue: how can we foster development without irreversible environmental degradation?
• Environmental Sustainability– How do we change the environment for
the better? (e.g. roads, paths on mountains, &c.)
– How do we change it for the worse? (e.g. pollution, overfishing, global warming, &c.)
• Potential correlations between environmental deterioration/protection and development 17
![Page 18: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/18.jpg)
Our Financial Legacy
• Key Issues: – what debts and capital do we leave to our
progeny (children & grandchildren)?– International indebtedness
• Our Financial Legacy–We borrow from the future to meet our
current needs– But we also develop capital (infrastructure,
knowledge & techniques, social/political/economic organization) that we bequeath
• Potential correlations between indebtedness and development
18

Also note the biblical allusions on the course schedule:
“And God blessed them, and God said unto them, Be fruitful, and
multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the
earth…”-- Genesis 1:28

This highlights the religious and moral aspects of
sustainability.
As we engage this, be sure to consider the bearing of various normative perspectives on this
issue.

By the late eighteenth century, the consensus
among political economists was that “populousness”—
having high population density—was a good thing…
23
![Page 24: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/24.jpg)
“Naturalisation is the shortest and easiest way of increasing your people, which all wise governments have encouraged by privileges granted to the fathers of children…And that because (1) People are the strength of any country or government…[and] (2) 'Tis the number of people that make the riches of any country.” – John Locke, “For a General Naturalization” (1693)
“This shews, how much numbers of men are to be preferd to largenesse of dominions, and that the increase of lands and the right imploying of them is the great art of government.” – John Locke, Second Treatise (1690)
![Page 25: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/25.jpg)
“In general, we may observe, that the question, with regard to the comparative populousness of ages or kingdoms, implies important consequences…But if every thing else be equal, it seems natural to expect, that, wherever there are most happiness and virtue, and the wisest institutions, there will also be most people.” – David Hume, “Of the Populousness of Ancient Nations” (1754)

In 1798, TR Malthus turned this conventional wisdom
on its head.
Who was TR Malthus?

Thomas Robert Malthus
• 1766-1834• Fellow, Jesus College,
Cambridge• Author, Essay on the
Principle of Population (1798)
• Challenged JB Say & D Ricardo; Antecedent to JM Keynes 27

The Principle of Population
• The Principle– Population grows geometrically (1, 2, 4,
8, &c.)–Means of subsistence grow
arithmetically (1, 2, 3, &c.)
• Checks to Population Growth– Positive: “…wars, pestilence, plague,
and famine.”– Preventative: Family planning
29

Malthus’ point was simple…
The earth has a limited carrying capacity.
And our demands constantly exceed the
Earth’s capacity to satisfy those demands.
30

International economic interchange might indeed
be zero-sum.

Political Implications of Scarcity
• Competition for scarce resources to provide better standard of living for offspring
• Competition between:– Political communities (e.g. oil, water)– Classes
• Tension between:– Reproductive rights– Share of resources
33

Malthus, for instance, had a very low discount rate—perhaps even an inverse
discount rate.
He was willing to inflict suffering in the present to minimize suffering in the
future...34
![Page 35: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/35.jpg)
Malthus on the Evils of Charity
“All parish assistance should be most rigidly denied [the poor man]: and if the hand of private charity be stretched forth in his relief, the interests of humanity imperiously require that it should be administered very sparingly. He should be taught to know that the laws of nature, which are the laws of God, had doomed him and his family to starve for disobeying their repeated admonitions.”
--TR Malthus 35

TR Malthus’ dire predictions led the historian Thomas Carlyle to brand political
economy “the dismal science.”
Many “Malthusians” have followed in this “[d]reary, stolid, dismal” tradition.

20th Century Pessimists
• Postwar baby boom inspired concerns• Harrison, Make Room! Make Room!
(1966)– Predicted 7bn humans in 1999 (actually
6bn)– Crisis: rationing and social disorder
• Ehrlich, The Population Bomb (1968)– “the battle to feed humanity is over”– Predicted massive famines in 1970s and
1980s– US population would be at just 22m in 1999 38
![Page 39: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/39.jpg)
In fact, all of these dire predictions were wrong.
Population growth has not exceeded the rate of
increase in the means of subsistence.

Many commentators have suggested that Malthus
forgot about the power of technology…

The result is that the production possibilities frontier—the carrying
capacity of the Earth—has been expanded.
New technology—techniques and processes—have increased the number
of people the Earth can support. 44

Malthus might have offered several responses…
45
![Page 46: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/46.jpg)
(1) The preventative check.
Population has only been growing arithmetically
because we have done a good job of deliberately
limiting our rate of increase.
46
![Page 47: Economic Development & Population Growth Lec 18 – Tuesday, 15 November 2011 J A Morrison 1 Liverpool St Station (London) Crowd at Trade Fair (Delhi)](https://reader035.vdocuments.us/reader035/viewer/2022070406/56649e0c5503460f94af505f/html5/thumbnails/47.jpg)
(2) The constraint still exists.
Just because we haven’t reached the ultimate limit yet doesn’t mean it doesn’t exist.
Malthus would surely point to increasing environmental
degradation as generating the potential final limit to
population growth.47

“If only Malthus, instead of Ricardo, had been the
parent stem from which nineteenth-century
economics proceeded, what a much wiser and richer
place the world would be to-day!”

Do you think Keynes was right?
In what ways would our understanding of development benefit from the insights of TR
Malthus and the modern Malthusians?
What is the relevance of Malthus today? 50

One of the key questions centers on the relationship
between economic development and
population growth.
Simply put, were Locke & Hume right or was Malthus?
Does populousness bring riches or poverty? 52

So, Locke & Hume may have been misguided:
The poorest countries in the world have some of the fastest
population growth rates.
And the world’s richest countries have some of the slowest population growth
rates. 55

But which is cause and which is effect?

If population growth rates are inversely related to development, then we might consider making more extensive use of Malthus’ preventative
check.

But the politics here get very heated very quickly.
And as it should be…
This is an issue of reproductive rights,
involving the “right to choose” how many children
to have. 58

Across time and space, many states have sought to
regulate the rate of population growth…

Eugenics in early 20th C• Assumption: lower classes proliferate the
most• Goal: limit population growth, particularly
of “undesirables”• Enjoyed prominent advocates: M Sanger,
W Wilson, T Roosevelt, W Churchill, & JM Keynes
• 1907: Indiana passes first US Eugenics Law
• 1924: Virginia orders compulsory sterilization of mentally disabled Challenged in US Sup Ct case Buck v. Bell

“We have seen more than once that the public welfare may call upon the best
citizens for their lives. It would be strange if it could not call upon those who already sap
the strength of the State for these lesser sacrifices, often not felt to be such by those
concerned, in order to prevent our being swamped with incompetence. It is better for all the world, if instead of waiting to execute
degenerate offspring for crime, or to let them starve for their imbecility, society can prevent those who are manifestly unfit from continuing their kind…Three generations of
imbeciles are enough.”
-- Opinion of Justice Oliver Wendell Holmes in Buck v. Bell (1927)

The Virginia law was upheld in an 8-1 opinion.
That was in 1927.
Within a decade, the Eugenics movement in the West had picked up a lot of
steam…62

The Nazis were fully committed to Eugenics. 63

Population control—although not necessarily
eugenics—continues today…

China’s One Child Policy
• Restricts urban couples to just having 1 child per family (with some exceptions)
• Implemented in 1979• Affects more than 1/3rd of
Chinese population• Strong domestic support• But potential increase in forced
abortions & infanticide65

Clearly, Malthus’ insight seems sharpest when
viewed through the lens of environmental politics.
“Indeed, in an era of global warming, Malthus may prove
among the most-relevant philosophers of the
Enlightenment.” – Robert D. Kaplan 67
