rapid and sustained increase in output that
began in the Western world with the Industrial
Revolution.

CHAPTER 32 Long-Run Growth
 FIGURE 32.1 Economic
Growth Shifts Society’s Production
Possibility Frontier Up and to the
Right
The production possibility frontier
shows all the combinations of
output that can be produced if all
society’s scarce resources are
fully and efficiently employed.
Economic growth expands
society’s production possibilities,
shifting the ppf up and to the right.

The Growth Process: From Agriculture to Industry
From Agriculture to Industry: The Industrial Revolution
CHAPTER 32 Long-Run Growth
Beginning in England around 1750, technical
change and capital accumulation increased
productivity significantly in two important
industries: agriculture and textiles.
More could be produced with fewer resources,
leading to new products, more output, and wider
choice.
A rural agrarian society was very quickly
transformed into an urban industrial society.

CHAPTER 32 Long-Run Growth
Among the sources of increased productivity and growth in England
around 1750 was:
a.
Technical change and capital accumulation.
b.
New and more efficient methods of farming.
c.
New inventions and new machinery.
d. All of the above.

The Growth Process: From Agriculture to Industry
Growth in Modern Society
CHAPTER 32 Long-Run Growth
Economic growth continues today, and while the
underlying process is still the same, the face is
different.
Growth comes from a bigger workforce and more
productive workers. Higher productivity comes
from tools (capital), a better-educated and more
highly skilled workforce (human capital), and
increasingly from innovation and technical change
(new techniques of production) and newly
developed products and services.

catch-up The theory stating that the growth rates
of less developed countries will exceed the growth
rates of developed countries, allowing the less
developed countries to catch up.

The Sources of Economic Growth
aggregate production function The
mathematical representation of the relationship
between inputs and national output, or gross
domestic product.
CHAPTER 32 Long-Run Growth
An increase in GDP can come about through
1.
An increase in the labor supply.
2.
An increase in physical or human capital.
3.
An increase in productivity (the amount of
product produced by each unit of capital or
labor).

The Sources of Economic Growth
An Increase in Labor Supply
labor productivity Output per worker hour; the
amount of output produced by an average worker
in 1 hour.

CHAPTER 32 Long-Run Growth
In order for economic growth to increase the standard of living:
a.
The rate of output growth must exceed the rate of population
increase.
b.
Income must be distributed equally.
c.
The government must practice industrial policy.
d.
Citizens must experience improvements in the quality of life.

The Sources of Economic Growth
Increases in Productivity
Economies of Scale
External economies of scale are cost savings that
result from increases in the size of industries.
CHAPTER 32 Long-Run Growth
Other Influences on Productivity
In addition to technological change, other
advances in knowledge, and economies of scale,
other forces may affect productivity.

Sustainability of Resource Extraction Growth Strategies
CHAPTER 32 Long-Run Growth
Much of Southeast Asia has fueled its growth
through export-led manufacturing. For countries
that have based their growth on resource
extraction, there is another set of potential
sustainability issues.
Because extraction can be accomplished without a
well-educated labor force, while other forms of
development are more dependent on a skilledlabor base, public investment in infrastructure is
especially important.
