You must decide how many workers to allocate to the production of RED stuff and how many to allocate to the production of BLUE stuff.
Your goal is to attain the most happiness for your country.

Are we thinking about the problem correctly?
When you choose to produce more RED stuff, what do you give up?
When you choose to produce more BLUE stuff, what do you give up?A country doesn’t give up workers when it produces stuff.It gives up the other stuff it could be producing instead.
The opportunity cost of BLUE stuff isn’t a worker.
The opportunity cost of BLUE stuff is RED stuff!
31
How many RED stuff does West have to give up to produce 1 more unit of BLUE stuff? In West, the cost of 1 BLUE stuff is 2 RED stuff.
or
32
How many RED stuff does West have to give up to produce 1 more unit of BLUE stuff? In West, the cost of 1 BLUE stuff is 2 RED stuff.
How many BLUE stuff does West have to give up to produce 1 more unit of RED stuff? In West, the cost of 1 RED stuff is 1/2 of a BLUE stuff.
or
33
How many RED stuff does East have to give up to produce 1 more unit of BLUE stuff?
or
In East, the cost of 1 BLUE stuff is 1/2 RED stuff.
In East, the cost of 1 RED stuff is 2 BLUE stuff.
34
West has a relative advantage in the production of RED stuff.
In West, 1 unit of RED costs ½ unit of BLUE.
In East, 1 unit of RED costs 2 units of BLUE.
=
=
East has a relative advantage in the production of BLUE stuff.
In West, 1 unit of BLUE costs 2 units of RED.
In East, 1 unit of BLUE costs ½ unit of RED.

35
What does RED stuff cost?
In West, 1 unit of RED equals ½ unit of BLUE.
In East, 1 unit of RED equals 2 units of BLUE.
=
=
West will export RED if West can get more than ½ BLUE.
East will import RED if East can pay less than 2 BLUE.
36
What does BLUE stuff cost?
In West, 1 unit of BLUE equals 2 units of RED.
In East, 1 unit of BLUE equals ½ unit of BLUE.

=
West will import BLUE if West can pay less than 2 RED.
East will export BLUE if East can get more than ½ RED.
37
Conclusions:
1. Trade is a positive sum relationship.
2. Exchanging goods and services is what’s important. Money is only a tool that facilitates the exchanging.
3. By definition, every country has a relative advantage in something.
4. Trade is the combination of exchange and specialization. Specialization is the directing of resources toward a country’s relative advantage.
38
Why is trade controversial?
Practical
On the whole, societies are better off with trade though some individuals are not.
Philosophical
There are differences of opinion as to the nature of trade.
39
Protectionist Assumption:
Trade leads to a centralization of political power, decreased competition, exploitation, and the concentration of wealth.
Free Trade Assumption:
Trade leads to a decentralization of political power, increased competition, empowerment, and the dissemination of wealth.
40
Income
Protectionist argument:
Trade results in increased income for one country at the expense of reduced income for the other country.
Free Trade argument:
Trade results in increased incomes for both trading partners.

While the number of American jobs in manufacturing has been declining, American production of industrial goods has been rising. This implies that American manufacturing is becoming more efficient as it produces ever more output using less labor.
