1. Know the definition of comparative advantage
One entity can produce something at a LOWER MARGINAL OPPORTUNITY
COST than another entity.
2. Set up a table:
Ireland Puerto Rico
1 Rum = __Crystal Rum = __Crystal
1 Crystal = __ Rum Crystal = __Rum
3. Go to the Xtremes (X and Y Games)

Ireland produce?
1 million cases
How much rum should Puerto Rico produce?
80,000 barrels
Should Ireland just hold onto its cases of crystal and Puerto Rico just
hold onto its barrels of rum?
NO!
What should each country do after specialization?
Trade
