Question

Difficulty: MediumTheories of International Trade (Absolute and Comparative Advantage)

Match each classical international trade concept on the left with its corresponding economic definition or condition on the right.

  • Absolute AdvantageThe ability of a country to produce a good using fewer real inputs or labor-hours per unit than another country.
  • Comparative AdvantageThe ability of a country to produce a good at a lower relative sacrifice of an alternative commodity than another country.
  • Opportunity CostThe quantity of one good that must be foregone to produce one additional unit of another good.
  • Mutually Beneficial Terms of TradeAn international relative price ratio set strictly between the domestic opportunity cost ratios of the trading partners.

Answer

Absolute Advantage pairs with producing a good using fewer real inputs or labor-hours per unit; Comparative Advantage pairs with producing a good at a lower relative sacrifice of an alternative commodity; Opportunity Cost pairs with the quantity of one good foregone to produce another; and Mutually Beneficial Terms of Trade pairs with an international price ratio set between domestic cost limits.
Absolute advantage evaluates efficiency in terms of direct resource inputs, whereas comparative advantage evaluates efficiency in terms of foregone alternative production. Opportunity cost represents the real commodity trade-off required, and mutually beneficial terms of trade must fall between the domestic opportunity cost limits of the participating countries.

Step-by-Step Solution

1
Identify the primary criterion for Absolute Advantage.
Absolute advantage focuses on absolute efficiency (fewer input resources or labor-hours needed).
Adam Smith defined absolute advantage through absolute input superiority.
2
Identify the primary criterion for Comparative Advantage.
Comparative advantage focuses on relative efficiency or lower opportunity cost.
David Ricardo showed that trade benefits depend on relative cost differentials rather than absolute superiority.
3
Define Opportunity Cost in trade theory.
It represents the trade-off ratio between two goods.
Gottfried Haberler reformulated comparative advantage using opportunity cost curves.
4
Determine the condition for mutually beneficial exchange.
The terms of trade exchange rate must be strictly bounded by the domestic cost ratios of both nations.
If terms of trade fall outside these bounds, at least one nation would be worse off trading than remaining self-sufficient.
