Specialisation and Trade

Specialisation relies on trade because economies need to buy the things that they have not specialised in from other countries. Finland produces a lot of paper, but it may need to buy cars from a country like Germany that has specialised in car production.

Specialised economies need trade

Specialised economies need trade

  • Specialisation means countries often stop making products they need, to focus on producing the products they are better at.
  • As a result, trade must happen with other countries, and an efficient exchange system is needed.
  • Money is often used as this medium of exchange because everyone values money.

Comparative Advantage

Free trade can allow countries to specialise in the goods they are most efficient at producing. Trade means that they can buy some goods from other countries, rather than producing them themselves.

Opportunity cost of production

Opportunity cost of production

  • If a country produces sugar, it has an opportunity cost of production.
  • The labour and capital used to make sugar cannot be used to make wheat at the same time.
    • E.g. if Brazil can produce a lot of sugar cane per acre but not much wheat, and the US can produce a lot of wheat but not sugar cane, then the US has a lower opportunity cost of producing wheat than Brazil.
  • This can be shown using production possibility frontiers (PPFs).
Comparative advantage

Comparative advantage

  • The US has a comparative advantage in producing wheat.
  • Brazil has a comparative advantage in producing sugar cane.
  • If both countries could specialise in producing the goods they had a comparative advantage in, then:
    • The total world output of goods will rise.
    • Brazil and the US can trade wheat for sugar cane, and they both benefit.
  • Think of comparative advantage as what a country is least bad at - they all have to produce something!
Absolute advantage

Absolute advantage

  • A country has an absolute advantage in producing a good over another country if it uses fewer resources to produce that good.
    • E.g. if Saudi Arabia can produce corn and oil more efficiently than the US, but can only produce 100 barrels of oil or 25 bushels of corn, the opportunity cost for Saudi of producing one barrel of oil is the loss of 0.25 bushels of corn.
  • If the US lost a bushel of corn by producing one barrel of oil, then the US has a comparative, but not absolute advantage in corn.
Costs of international trade

Costs of international trade

  • Negative externalities such as pollution from freight.
  • Risk of structural/regional unemployment because employers relocate.
  • While international trade may benefit skilled workers, it can be bad for low-skilled workers.
  • Low-skilled workers in developed countries compete against extremely low wage workers worldwide, which is unsustainable.
