  • Card

    Absolute vs comparative advantage?

    Absolute: produce more with same resources. Comparative: lower opportunity cost — basis for trade even if one country is absolutely better at everything.

  • Card

    Opportunity cost ratio?

    What must be given up of Good A to produce one more unit of Good B — country with lower OC has comparative advantage in B.

  • Card

    Gains from trade?

    Specialisation and exchange allow consumption combinations outside the pre-trade PPF — both countries can consume more than autarky.

  • Card

    Terms of trade?

    Index of export prices ÷ index of import prices × 100. Improvement means export prices rise relative to import prices.

  • Card

    When does trade benefit both countries?

    When the terms of trade lie between the two countries' opportunity cost ratios — each gains by exporting its comparative advantage good.

  • Card

    Limitations to free trade theory?

    Transport costs, immobile factors, protectionism, and unequal gains (some groups lose from specialisation).

  • Card

    What is comparative advantage?

    The ability of a country to produce a good or service at a lower opportunity cost than its trading partners. This is the fundamental principle underpinning modern trade theory.

  • Card

    State the formula for the Terms of Trade (ToT).

    Terms of Trade = (Index of average export prices / Index of average import prices) x 100. The base year is always 100.

  • Card

    How does trade allow a country to consume beyond its PPC?

    By specialising in producing the good where it has a comparative advantage and trading its surplus, a country can import other goods more cheaply than it could produce them domestically. This allows for a combination of goods for consumption that lies outside its own production possibilities.

  • Card

    What is the key difference between absolute and comparative advantage?

    Absolute advantage is based on using fewer inputs (higher productivity), while comparative advantage is based on having a lower opportunity cost. Trade can be beneficial based on comparative advantage even if one country has an absolute advantage in all goods.

  • Card

    What condition must be met for the Terms of Trade to be mutually beneficial?

    The agreed Terms of Trade (the rate of exchange between goods) must lie between the pre-trade opportunity cost ratios of the two trading countries.
