Chapter 9
Global
Economic
Growth and
Development
Introduction
About half of all U.S. engineers and
computer scientists with Ph.D. degrees
were born outside the United States.
In this chapter, you will learn why
countries that attract and retain the
world’s brainiest and hardest-working
people tend to experience the highest
sustained rates of economic growth.

Did You Know That...
• Only one European nation,
Luxembourg, has per capita real GDP
higher than the U.S. per capita GDP?
• Per capita GDP has grown more rapidly
in some U.S. states than in some
European nations?
• These states have experienced a
higher rate of economic growth?

How Do We Define
Economic Growth?
• Economic growth can be shown
graphically by shifting the production
possibilities curve outward.
• Economic growth reflects the fact that
more of all goods can be produced
within the economy.

Productivity Increases: The Heart
of Economic Growth
Economic growth = Rate of growth of capital +
Rate of growth of labor +
Rate of growth in the productivity
of capital and of labor

Productivity Increases: The Heart
of Economic Growth (cont'd)
• Labor Productivity
 Total real domestic output (real GDP)
divided by the number of workers
(output per worker)

Example: Is Official Labor
Productivity Growth Overstated?
• BLS reports U.S. labor productivity has
increased by at least 21% since 2000.
• Self-employed people, managers, part-time,
and temporary employees are excluded.
• Including these forms of labor might reduce
productivity to as low as 11%.

Saving: A Fundamental Determinant
of Economic Growth
• To have more consumption in the
future, you must consume less today
and save the difference between your
consumption and your income.

New Growth Theory and
What Determines Growth
• New Growth Theory
 A theory of economic growth that
examines the factors that determine why
technology, research, innovation, and the
like are undertaken and how they interact

9-25
New Growth Theory and
What Determines Growth (cont'd)
• Technology: a separate factor
of production
 The greater the rewards, the more
technological advances we will get.

9-26
New Growth Theory and
What Determines Growth (cont'd)
• Research and development (R&D)
 Patents
 A government
protection that gives an inventor
the exclusive right to make, use, or sell an
invention for a limited period of time (currently,
20 years)

9-27
New Growth Theory and
What Determines Growth (cont'd)
• Research and development (R&D)
 Positive externalities and R&D
 For
every 1% rise in the stock of R&D in the
United States alone, productivity worldwide
increases by about 0.25%.

Immigration, Property Rights,
and Growth (cont'd)
• Question
 How can well-defined property rights
stimulate economic growth?
• Answers
 The more certain property rights are, the
more capital accumulation there will be.
 The more certain are property rights, the
more entrepreneurship there will be.

 The U.S. poverty level exceeds the
average income of one-half the world.

• The relationship between population
growth and economic development

Issues and Applications: Winners
and Losers in the Brain-Drain Game
• The losers: nations with huge outflows
of human capital; this damages
prospects for economic growth.
• The winners: countries receiving highly
skilled workers who immigrate and
provide a “brain-gain.”

Summary Discussion
of Learning Objectives
• Economic growth
 The rate of economic growth is the annual
rate of change in per capita GDP.
• Why economic growth rates
are important
 Over long intervals, relatively small
differences in the economic growth
rate can produce large disparities in
per capita incomes.

Summary Discussion
of Learning Objectives (cont'd)
• Why productivity increases are crucial
for maintaining economic growth
 For a nation with a stable population and
steady capital growth, productivity growth
is the main factor in economic expansion.

Summary Discussion
of Learning Objectives (cont'd)
• Fundamental factors that contribute to a
nation’s economic development

a strong system of property rights,
allow creative destruction, and avoid
protectionism have higher levels of
economic development.
