Which concept explains why a country or producer should specialize in goods that can be produced at lower opportunity costs relative to others?

• A. Absolute advantage
• B. Substitution principle
• C. Comparative advantage
• D. Quaternary activity

Answer: (C)

The idea being tested is that specialization should be based on comparative advantage, which comes from comparing opportunity costs. A country should focus on producing the goods for which it sacrifices the fewest resources or the smallest amount of other goods to produce one more unit. When each country does this, overall production rises and trade allows everyone to consume more than they could alone. Think of it this way: what matters is not who can produce more in absolute terms, but who gives up less of one good to produce another. Even if a country is better at producing both goods, it should still concentrate on the good with the lower opportunity cost relative to its trading partner. Then the two countries trade to obtain both goods more efficiently than if each tried to produce everything itself. For example, if Country A gives up fewer units of cloth to produce wine than Country B does, Country A has a comparative advantage in wine and should specialize in wine, while Country B should specialize in cloth. Through trade, both countries end up with more wine and more cloth than if they tried to produce both goods on their own. That’s why the concept highlighted is comparative advantage.
