Comparative Advantage
• The reason the opportunity cost of guns increases
as we produce more guns is that some resources
have comparative advantage over other resources
• A resource has comparative advantage if it has
the ability to be better suited to the production of
one good than another

The Benefits from Trade
• When people freely enter into trade, both parties can be
expected to benefit from trade
Textiles (yds)
Without trade, each
country can only consume
those combinations of
goods along their PPCs

The Benefits from Trade
If each country specializes according to
comparative advantage and trades,
they can consume beyond their PPCs

Application: U.S. Textile Production and Trade
• Two hundred years ago, the U.S. had a comparative
advantage in textile production
• Now, countries with cheaper labor (such as Bangladesh)
have the comparative advantage in textiles
• The gains from trade are higher wages for workers in
Bangladesh and lower-priced cloth for U.S. consumers

Outsourcing, Trade and Comparative Advantage
Outsourcing
• Outsourcing is the relocation of production once done
in the United States to foreign countries
• Outsourcing occurs because many other countries have
a comparative advantage in labor costs
• The U.S. has comparative advantage in technology,
institutional structure, and specialized knowledge

Outsourcing, Trade and Comparative Advantage
Globalization
• Globalization is the increasing integration of
economies, cultures, and institutions across the world
• A positive effect of globalization is that it provides larger
markets than the domestic economy
• The global economy increases the number of
competitors and this increased competition can be a
negative effect of globalization

Outsourcing, Trade and Comparative Advantage
Exchange Rates and Comparative Advantage
• The U.S. comparative advantage in innovation results
in higher wages in the U.S.
• As industries mature, they move to lower wage countries
• In order to regain our comparative advantage, the U.S.
exchange rate will decline and foreign wages will
increase to make U.S. exports cheaper and imports to
the U.S. more expensive

Outsourcing, Trade and Comparative Advantage
The Law of One Price
• The law of one price is the wages of equal workers in
one country will not differ significantly from the wages of
workers in another institutionally similar country
• If the U.S. loses its comparative advantage based on
technology and institutional structure, U.S. wages will
decrease relative to wages in many other countries
The reality is that the citizens in the U.S. has
been living better than it could have otherwise
because of trade and outsourcing

Chapter Summary
• The production possibility curve embodies the
opportunity cost concept
• Increasing marginal opportunity cost exists
• Trade allows people to use their comparative advantage
and shifts out society’s combined production possibility
curve
• Efficient, inefficient and unattainable points on the PPC
• Through specialization and trade, countries can increase
consumption

Chapter Summary
• The typical outward bow of the PPC is the result
of comparative advantage and trade
• Because many goods are cheaper to produce in foreign
countries, production of goods formerly in the U.S. is being
outsourced
• Outsourcing is the product of the law of one price
• Globalization is the increasing integration of economies,
cultures, and institutions across the world
