The Rule of 70 (The Magic of Compounding)
The rule of 70:
Example: If real GDP per capita is growing at an
annual growth rate of 3.5%, it will double in:
The moral? Small improvements in growth add up
fast (the power of compounding).

Let's figure out how long it will take for the average Indian
to be as wealthy as the average Western European is
today. Note that all numbers are adjusting for inflation.
India's GDP per capita is $3,000, and let's say that real
output per person there grows at 5 percent per year. Using
the rule of 70, how many years will it take for India to reach
Italy's current level of GDP per capita, about $24,000 per
year?
a)42 years
b)14 years
c)28 years.
d)12 years

Understanding the Wealth
of Nations
The Factors of Production are important
Physical capital: the stock of tools including
machines, structures, and equipment.
Human capital: is the productive knowledge
and skills that workers acquire through
education, training and experience.
Technological knowledge: knowledge about
how the world works that is used to produce
goods and services.

What Causes Economic Growth?
BACK TO
Understanding the Wealth
of Nations
Why do some nations have faster growth
than others?
Besides factors of production, incentives and
institutions matter.
Institutions = “rules of the game” that
structure economic incentives.
Institutions of Economic Growth

Property rights
Honest government
Political stability
A dependable legal system
Competitive and open markets
BACK TO
Korea’s Experiment
Before division after WWII: similar
Culture, physical capital, technology.
North Korea became a communist state with a
centrally planned economy.
South Korea adopted the capitalist free market
model.

Institutions
1. Property rights:
Provide incentives to work hard.
Encourage investment and innovation.
Without property rights:
Effort is divorced from payment, reducing
incentives.
Free riders become a problem.
BACK TO
Institutions
Free Rider = someone who consumes a
resources without working or contributing to
the resource’s upkeep.
China’s “Great Leap Forward”- which introduced
farming collectives- reduced incentives. 20-40
million starved.
1978, farmers in Xiaogang met in secret to devise
a plan to keep some of their produce.

Productivity improved so quickly the government
allowed the experiment to proceed.
Food production increased 50% in 5 years 1978-1983.
BACK TO
Institutions
2. Honest Government
Property rights are meaningless unless
government guarantees property rights.
Corruption bleeds resources away from
productive entrepreneurs.
Corruption takes resources away from more
productive government activity.

Institutions
3. Political Stability
Changing governments without the rule
of law creates uncertainty which leads
to less investment in physical and
human capital.
In many nations civil war, military
dictatorship, and anarchy have
destroyed the institutions necessary for
economic growth.
Bullet casings from Liberia’s Civil War: Bad soil for anything to grow.
BACK TO
Institutions
4. Dependable Legal System
A good legal system facilitates
contracts and protects property from
others (including government).
Poorly protected property rights can
result from too much government or
too little government.
In India, residents who purchase land have
to do so more than once because of lack
of proper record keeping.
BACK TO
Institutions
5. Competitive and Open Markets
Encourage the efficient organization of
resources.
One study found: if India used its physical and
human capital as efficiently as the U.S., India
would be 4x richer than it is today.

Institutions
Why do poor countries use their capital
inefficiently?
Whether inadvertently or not, inefficient
and unnecessary regulations:
Create monopolies and impede markets
Example: until recently in India, it was illegal
to produce shirts using large-scale
production
Economies of scale = the advantages of large
-scale production that reduce average cost as
quantity increases

Property rights?
England’s geography and Navy helped protect property
rights
Honest government
Growth of Parliament (and religious changes) reduced
royal tyranny
Political stability
Middle class developed from growth
A dependable legal system
Less corruption as royal and Catholic power is reduced
Competitive and open markets
England opened itself more to trade
