Interdependence and Trade
Consider your typical day:
You wake up to an alarm clock made in Korea.
You pour yourself some orange juice made from
oranges grown in Florida.
You put on some clothes made of cotton grown in
Georgia and sewn in factories in Thailand.
You watch the morning news broadcast from New
York on your TV made in Japan.
You drive to class in a car made of parts
manufactured in a half-dozen different countries.
…and you haven’t been up for more than two hours
yet!

How do we satisfy our wants and
needs in a global economy?
We can be economically selfsufficient.
We can specialize and
trade with others,
leading to economic
interdependence.
Why is interdependence the
norm?
Interdependence occurs because
people are better off when they
specialize and trade with others.
What determines the pattern of
production and trade?
Patterns of production and
trade are based upon
differences in opportunity costs.
Why do countries trade?
International trade
allows a country to
consume a
combination of goods
and services that
exceeds its production
possibilities curve

A Parable for the Modern
Economy

Imagine . . .
only two goods: potatoes and meat
only two people: a potato farmer and a
cattle rancher


What should each produce?
Why should they trade?
Self-Sufficiency
By ignoring each other:
 Each consumes what they each produce.
 The production possibilities frontier is also
the consumption possibilities frontier.
Without trade, economic gains are
diminished.
The Farmer and the Rancher
Specialize and Trade
Each would be better off if they
specialized in producing the product they
are more suited to produce, and then
trade with each other.


The farmer should produce potatoes.
The rancher should produce meat.

Why should countries
specialize and trade?
Total world output
increases, and therefore,
the potential for greater
total world consumption
also increases
13
What conclusion can
we draw from this?
International trade allows a
country to consume a
combination of goods that
exceeds its production
possibilities curve
14
If countries specialize,
in what should they
specialize?
They should produce
those goods and services
in which they have a
comparative advantage
15
What is
comparative advantage?
The ability of a country
to produce a good at a
lower opportunity cost
than another country
16
What advantage
comparative advantage?
World output and consumption
are maximized when each
country specializes in
producing and trading goods
for which it has a comparative
advantage
17
What is
absolute advantage?
The ability of a country
to produce a good
using fewer resources
than another country
