If you could produce
anything for trade,
what would it be?
Why?
What human resources
do you have available?
What natural resources
do you have available?
What capital would you
need?
If you could produce anything, what
would it be?
What is comparative advantage?

What is it?
Why trade?
What is comparative advantage?


The voluntary
exchange of goods and
services
Occurs when the
expected gains
outweigh the costs

Specialization
Specializing in the
production of goods
and services that can
be produced at a lower
opportunity cost than
the cost a trading
partner would have to
pay to produce the
same products.
Comparative Advantage


Specialization
Based on comparative
advantage increases
the total output and
consumption of the
goods that are traded.
What happens to the
quantity of products
with specialization
based on comparative
advantage?
Comparative Advantage
Which were domestic?
Which were
international?
On a scale of 1 to 5, how
happy are you with the
item? Record on sheet.
You have two minutes to
trade within your group if you
want. You may now show
cards.

Relate activity to the real
world…what parallels do
you see?
Did more people trade in
round 1 or 2? Why?
Were you required to
trade?
Did anyone have a higher
rating in round one than
2? If so, how did that
happen?
The number of items to
trade remained the same,
but people were happier
at the end of which
round ___? Why?
Why were you willing to
trade?
Should the U. S. trade with
other countries? Why or
why not?

1. The opportunity cost
is the highest valued
alternative that is given
up when a choice is
made
For example:
Meat pizza, veggie pizza,
cheese pizza, salad-What
are your first and second
choices?
How do you relate to the
pizza shop?
What is your choice?
What is the opportunity
cost of your choices?


1. Two workers in a
pizza shop and then
two countries
2. Decide for each if
they should specialize
and trade
3. Key effect for each is
to increase the amount
of goods produced and
consumed

1. Comparative
Advantage occurs when
people or firms
specialize in the
production of a good or
service for which they
have a lower opportunity
cost.

cell phones and microwaves ovens in Country B?
2. Why does this occur?
3. If each country only produces cell phones, which country can
produce more cell phones?
4. If each country only produces microwave ovens, which country can

Who has an absolute
advantage in producing
microwaves?
When a worker can
produce more of a
good than a worker in
another country, the
worker in the first
country has an
absolute advantage in
producing that good.
