Question

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

Match each classical trade theory or economic principle on the left with its corresponding foundational premise or proponent on the right.

  • Absolute Advantage TheoryAdvocated by Adam Smith; trade is mutually beneficial when each nation produces a commodity at a lower direct labor cost.
  • Comparative Advantage TheoryFormulated by David Ricardo; trade relies on differences in relative opportunity costs rather than absolute production costs.
  • Opportunity Cost Theory of TradeIntroduced by Gottfried Haberler; explains trade advantages using marginal rates of transformation on production possibility curves.
  • Limits to Terms of TradeBounded by the domestic cost ratios of both trading partners, establishing the range for mutually profitable exchange.

Answer

Absolute Advantage Theory matches Adam Smith's absolute labor cost approach; Comparative Advantage Theory matches David Ricardo's relative opportunity cost model; Opportunity Cost Theory of Trade matches Gottfried Haberler's production possibility curve framework; Limits to Terms of Trade matches the domestic cost ratios boundary.
Each theory is paired correctly with its originator or core economic premise: Adam Smith established absolute advantage based on absolute cost efficiency; David Ricardo formulated comparative advantage based on relative cost ratios; Gottfried Haberler introduced the opportunity cost curve model; and the limits to the terms of trade are set by internal opportunity cost ratios.

Step-by-Step Solution

1
Identify the proponent and core assumption of Absolute Advantage.
Adam Smith proposed that countries should specialize in goods where they possess absolute labor cost advantages.
This establishes the historical origin of free trade theory.
2
Identify the proponent and core assumption of Comparative Advantage.
David Ricardo showed that mutual gains from trade occur whenever relative opportunity costs differ between nations.
This extends Smith's model to cases where one country is more efficient in all lines of production.
3
Identify Haberler's contribution to trade theory.
Gottfried Haberler reformulated comparative advantage using the opportunity cost concept derived from production possibility frontiers.
This removed the restrictive assumption of the labor theory of value.
4
Determine the condition for mutually beneficial terms of trade.
The terms of trade must fall between the domestic opportunity cost ratios of both trading countries.
If the exchange rate falls outside these bounds, at least one nation would experience a net loss from trade.
