Scarcity, Choice, and Opportunity Cost
• Human wants are unlimited, but
resources are not.
• Three basic questions must be
answered in order to understand an
economic system:
• What gets produced?
• How is it produced?
• Who gets what is produced?

• Every society has some system or mechanism
that transforms that society’s scarce resources
into useful goods and services.

• Capital refers to the things that are
themselves produced and then used to
produce other goods and services.
• The basic resources that are available
to a society are factors of production:
• Land
• Labor
• Capital

• Production is the process that
transforms scarce resources into
useful goods and services.
• Resources or factors of production
are the inputs into the process of
production; goods and services of
value to households are the outputs
of the process of production.

Scarcity and Choice
in a One-Person Economy
• Nearly all the basic decisions
that characterize complex
economies must also be made
in a single-person economy.
• Constrained choice and
scarcity are the basic concepts
that apply to every society.

in an Economy of Two or More

advantage over another in the
production of a good or service
if it can produce that product
using fewer resources.

Comparative Advantage
and the Gains From Trade
• Colleen has an absolute advantage in the
production of both wood and food because
she can produce more of both goods using
fewer resources than Bill.

• In terms of wood:
• For Bill, the opportunity cost of 8 bushels of food is 4 logs.
• For Colleen, the opportunity cost of 8 bushels of food is 8 logs.
• In terms of food:
• For Colleen, the opportunity cost of 10 logs is 10 bushels of food.
• For Bill, the opportunity cost of 10 logs is 20 bushels of food.

Specialization, Exchange
and Comparative Advantage
• According to the theory of
competitive advantage,
specialization and free
trade will benefit all
trading parties, even those
that may be absolutely
more efficient producers.

Capital Goods and Consumer Goods

to produce other goods and
services.

produced for present
consumption.

• Investment is the process of
using resources to produce
new capital. Capital is the
accumulation of previous
investment.

investment in capital is forgone

The Production Possibility Frontier

frontier (ppf) is a graph that
shows all of the combinations
of goods and services that can
be produced if all of society’s
resources are used efficiently.

is also called the marginal
rate of transformation
(MRT).

Economic Growth
• Economic growth is an
increase in the total output of the
economy. It occurs when a
society acquires new resources,
or when it learns to produce
more using existing resources.
• The main sources of economic
growth are capital accumulation
and technological advances.

Capital Goods and Growth
in Poor and Rich Countries
• Rich countries devote more
resources to capital
production than poor
countries.
• As more resources flow into
capital production, the rate
of economic growth in rich
countries increases, and so
does the gap between rich
and poor countries.

• In a command economy, a central
government either directly or
indirectly sets output targets,
incomes, and prices.
• In a laissez-faire economy,
individuals and firms pursue their
own self-interests without any central

Mixed Systems,
Markets, and Governments
Since markets are not perfect, governments
intervene and often play a major role in the
economy. Some of the goals of government are to:
• Minimize market inefficiencies
• Provide public goods
• Redistribute income
• Stabilize the macroeconomy:
• Promote low levels of unemployment
• Promote low levels of inflation
