Determining Absolute and Comparative Advantage

Introduction to International Trade

  • International trade: The exchange of goods and services between nations that is mutually beneficial.

  • Importance of determining what a country should specialize in for trade.

Example Countries and Goods

  • Focus: United States and South Korea.

  • Goods: Apples and smartphones.

  • Production possibilities table demonstrates different amounts of each good that each country can produce with fixed resources.

    • USA: 39 apples or 13 smartphones.

    • South Korea: 24 apples or 12 smartphones.

Production Possibilities

  • Production Possibilities:

    • Fixed resources limit simultaneous production of both goods.

    • If resources allocated solely for apples:

      • USA: 39 apples; South Korea: 24 apples.

    • If allocated for smartphones:

      • USA: 13 smartphones; South Korea: 12 smartphones.

  • Graphical representation with production possibilities curves (PPC):

    • Purple line for USA.

    • Green line for South Korea.

Absolute Advantage

  • Absolute Advantage: A country can produce more of a good than another using the same amount of resources.

    • The USA has an absolute advantage in both apples and smartphones.

    • Efficiency comparison shows the USA can produce more of both goods than South Korea.

Comparative Advantage

  • Comparative Advantage: A country can produce a good at a lower opportunity cost than another country.

  • Opportunity Cost: The foregone alternatives when allocating resources to produce a particular good.

Calculating Opportunity Cost

  1. For Apples:

    • USA:

      • Producing 39 apples costs 13 smartphones.

      • Opportunity cost: 1 apple = 1/3 smartphone (or 0.33 smartphones).

    • South Korea:

      • Producing 24 apples costs 12 smartphones.

      • Opportunity cost: 1 apple = 0.5 smartphones.

    • Conclusion: USA has a comparative advantage in apples (lower opportunity cost).

  2. For Smartphones:

    • USA:

      • Producing 13 smartphones costs 39 apples.

      • Opportunity cost: 1 smartphone = 3 apples.

    • South Korea:

      • Producing 12 smartphones costs 24 apples.

      • Opportunity cost: 1 smartphone = 2 apples.

    • Conclusion: South Korea has a comparative advantage in smartphones (lower opportunity cost).

Implications of Comparative Advantage

  • Trade should be based on lower opportunity costs rather than absolute production amounts.

  • If both countries specialize according to their comparative advantages, they can benefit from trade:

    • USA specializes in apples.

    • South Korea specializes in smartphones.

  • This allocation of resources allows both countries to trade effectively and improve their overall economic positions.

Conclusion and Next Steps

  • Anticipation for the next video: To explore how gains from trade can be illustrated with PPC diagrams using the previous data.

  • Focus on how specializing based on comparative advantage can improve quality of life for both nations.
