LECTURE 3: PRODUCTION AND GROWTH
LECTURE 3: PRODUCTION AND GROWTH
Key questions: Why some nations are very rich, while others are
very poor? Why some nations have higher growth rates than
others? Why some nations in East Asia become prosperous
after 30 years, meanwhile many African nations have no signal of growth
ECONOMIC GROWTHDefinition:Economic growth is the increase in the market value
of the goods and services produced by an economy over time.
ECONOMIC GROWTH Rule of 70:Number of years for variable to double = 70/annual
growth rate of variable
Eg: You deposit 30M into a bank, the annual interest
rate is 7%, your account balance will be doubled after 10 years: 30 x (1+1%)10 = 60
CATCH-UP EFFECT
The catch-up effect refers to the property whereby countries that start off poor tend to grow more rapidly than countries that start off rich.
CATCH-UP EFFECT
MEASURING ECONOMIC GROWTH Economic growth is conventionally measured as
the percent rate of increase in real gross domestic product, or real GDP.

ROLE OF ECONOMIC GROWTH Living standard of one nation depends on its ability
to produce goods and services
Living standard increases when economy grows
Economic growth means unemployment reduces
THE VARIETY OF GROWTH RATES
ECONOMIC GROWTH AROUND THE WORLD Living standards, as measured by real GDP per
person, vary significantly among nations.
The poorest countries have average levels of income that have not been seen in the United States for many decades.
ECONOMIC GROWTH AROUND THE WORLD Annual growth rates that seem small become large
when compounded for many years. Compounding refers to the accumulation of a
growth rate over a period of time.
VIETNAM ECONOMIC GROWTH RATE(2000 - 2012)
PRODUCTIVITY AND LONG-RUN ECONOMIC GROWTH
Productivity refers to the amount of goods and services that a worker can produce from each hour of work (output per worker)
Productivity plays a key role in determining living standards for all nations in the world.
Higher productivity is the only source of long run growth in real GDP per capita.
PRODUCTIVITY AND LONG-RUN ECONOMIC GROWTH
To understand the large differences in living standards across countries, we must focus on the production of goods and services.
DETERMINANTS OF PRODUCTIVITY- The inputs used to produce goods and services are
called the factors of production.- The factors of production directly determine
productivity.- The factors of production:
physical capital human capital natural resources technological knowledge.
DETERMINANTS OF PRODUCTIVITY Physical Capital
is a produced factor of production. It is an input into the production process that in the past was
an output from the production process.
is the stock of equipment and structures that are used to produce goods and services. Tools used to build or repair automobiles. Tools used to build furniture. Office buildings, schools, etc.
DETERMINANTS OF PRODUCTIVITY Human Capital
the economist’s term for the knowledge and skills that workers acquire through education, training, and experience Like physical capital, human capital raises a nation’s ability to
produce goods and services.
Eg: German after WW2
DETERMINANTS OF PRODUCTIVITY Natural Resources
inputs used in production that are provided by nature, such as land, rivers, and mineral deposits. Renewable resources include trees and forests. Nonrenewable resources include petroleum and coal.
can be important but are not necessary for an economy to be highly productive in producing goods and services.
Eg: Arab Saudi, Japan
DETERMINANTS OF PRODUCTIVITY Technological Knowledge
Society’s understanding of the best ways to produce goods and services.
FYI: THE PRODUCTION FUNCTION Y = A F(L, K, H, N)
Y = quantity of output A = available production technology L = quantity of labor K = quantity of physical capital H = quantity of human capital N = quantity of natural resources F( ) is a function that shows how the inputs are
combined.
ECONOMIC GROWTH AND PUBLIC POLICY
Government Policies That Raise Productivity and Living Standards Encourage saving and investment. Encourage investment from abroad Encourage education and training. Establish secure property rights and maintain political
stability. Promote free trade. Promote research and development.
