Chapter Goals
• Demonstrate opportunity cost with a production
possibility curve
• Discuss the increasing marginal opportunity cost
• Relate the concept of comparative advantage to the
production possibility curve
• Show how through comparative advantage and trade, a
country can consume beyond their production possibility
• Explain how globalization and outsourcing are part of a
global process guided by the law of one price

The Production Possibilities Model
• The production possibilities model can be presented
in both a table and in a graph
• A production possibility table lists a choice’s
opportunity cost by summarizing what alternative
outputs you can achieve with your inputs
• An output is a result of an activity
• An input is what you put in production process
to achieve an output

The Production Possibilities Model
• A production possibility curve (PPC) is a curve
measuring the maximum combination of outputs that
can be obtained from a given number of inputs
• It is a graphical representation of the opportunity
cost concept
• A PPC is created from a production possibility
table by mapping the table in a two-dimensional
graph

Increasing Marginal Opportunity Cost
The principle of increasing marginal
opportunity cost states that opportunity costs
increase the more you concentrate on the activity
Butter
A
• Slope is flat at A
• This means there is a low opportunity
cost to produce more guns
B
• Slope is steep at B
• This means there is a high
opportunity cost to produce more guns
Guns

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

Productive efficiency is achieving as
much output as possible from a given
amount of inputs or resources

Distribution and Productive Efficiency
• The productive possibility curve focuses on efficiency
and ignores distribution
• If a method of production will change income distribution
we cannot determine if that method is efficient or not
• Efficiency has meaning when analyzing a
particular goal
• In our society, most people prefer more to less, and
many policies have relatively small distribution effects

Trade and Comparative Advantage
• The PPC is bowed because individuals specialize in the
production of goods for which they have a comparative
advantage
• For a society to produce on its PPC, individuals must
produce those goods for which they have a comparative
advantage and trade for other goods
• According to Adam Smith, humankind’s proclivity to
trade leads to individuals using their comparative
advantage

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

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
