    Study Notes

    Production Possibilities Frontier (PPF)

    • The PPF shows the maximum amount of two goods that can be produced with a fixed amount of resources.
    • The PPF is derived from simple linear production functions for each good.
    • The slope of the PPF represents the opportunity cost of producing one good in terms of the other, or the marginal technical rate of substitution (MRTS).
    • The opportunity cost is the amount of one good that must be given up to produce one more unit of the other good.

    Absolute vs. Comparative Advantage

    • A country has an absolute advantage in the production of a good if it can produce more of that good than another country, using the same amount of resources.
    • A country has a comparative advantage in the production of a good if it can produce that good at a lower opportunity cost than another country.
    • Comparative advantage is the basis for international trade. Countries can benefit from trade even if they do not have an absolute advantage in any good.

    Specialization and Trade: The Ricardian Model

    • The Ricardian model is a simple model of international trade that focuses on differences in productivity across countries.
    • The model assumes that countries have different technologies, and that labor is the only factor of production.
    • The model predicts that countries should specialize in the production of goods in which they have a comparative advantage.
    • In the Ricardian model, trade leads to an increase in global production and consumption of both goods, making countries better off.

    Consumption with No Trade (Autarky)

    • In autarky, countries produce and consume only what they produce themselves.
    • The consumption level under autarky is determined by the country's own PPF.

    Specialization and Trade

    • When countries specialize in the production of goods in which they have a comparative advantage and trade with each other, they can achieve a higher level of consumption than they could in autarky.
    • The trade line shows all possible combinations of goods that a country can consume with trade.
    • The price of goods in the international market must be between the opportunity costs of production for both countries for trade to occur.

    Production Possibilities Frontier

    • The Production Possibilities Frontier (PPF) shows the maximum amount of goods and services that can be produced with a fixed amount of resources.
    • The PPF is a downward-sloping curve because resources are scarce and have alternative uses.
    • The slope of the PPF represents the opportunity cost of producing one good in terms of the other.
    • The opportunity cost of producing one good is the amount of the other good that must be given up.

    Absolute and Comparative Advantage

    • Absolute Advantage: A country has an absolute advantage in producing a good if it can produce more of that good than any other country using the same amount of resources.
    • Comparative Advantage: A country has a comparative advantage in producing a good if it can produce that good at a lower opportunity cost than another country.
    • A country can benefit from trade even if it does not have an absolute advantage in any good as long as it has a comparative advantage in at least one good.

    Specialization and Trade: The Ricardian Model

    • The Ricardian Model is a simple model of international trade that assumes countries have different technologies and specialize in producing goods that use those technologies more efficiently.
    • The Ricardian Model predicts that countries will specialize in producing the goods in which they have a comparative advantage and trade with other countries to obtain the goods in which they have a comparative disadvantage.
    • In the Ricardian Model, both countries can gain from trade, as they are able to consume more of both goods than they could if they were to produce everything themselves.
    • The gains from trade are larger when the differences in opportunity costs are greater.

    Conditions for Trade to Occur

    • For countries to trade, the relative price of goods must be between their opportunity costs.
    • If the relative price of a good is below the opportunity cost of producing it in a country, then that country will import that good.
    • If the relative price of a good is above the opportunity cost of producing it in a country, then that country will export that good.

    International Trade II

    • Countries trade because they have different technologies, endowments of capital and labour, and consumer tastes.
    • The Ricardian model focuses on differences in technologies to explain trade.

    Production Possibilities Frontier (PPF)

    • A PPF represents the maximum combinations of two goods that can be produced with a fixed amount of resources.
    • The slope of the PPF represents the opportunity cost of producing one good in terms of the other.
    • The opportunity cost is the amount of one good that must be sacrificed to produce an additional unit of the other good.
    • Example: In the US, one unit of labor can produce 8 units of services or 2 units of manufactures. This relationship can be described by the PPF: Ys = 1600 – 4Ym, where Ys is the quantity of services produced and Ym is the quantity of manufactures produced.
    • This PPF has a slope of -4. This means that the opportunity cost of producing one unit of manufactures is 4 units of services. Alternatively, Ym = 400 – 1/4 Ys, which indicates that the opportunity cost of producing one unit of services is 1/4 units of manufactures.

    Absolute vs. Comparative Advantage

    • Absolute advantage occurs when one country can produce more of a good than another country using the same amount of resources.
    • Comparative advantage occurs when one country has a lower opportunity cost of producing a good than another country.
    • Countries should specialize in producing the good where they have a comparative advantage and trade for goods where they have a comparative disadvantage.
    • This is because specializing increases global output, and trade allows countries to consume more of both goods.

    Specialisation and Trade: The Ricardian Model

    • In the absence of trade (autarky), countries produce and consume at a point on their PPF.
    • Example: If the US produces 533 1/3 unites of services and manufactures, it consumes the same. China also consumes 533 1/3 unites of services and manufactures with no trade.
    • Specialization increases global production. The US should specialize in services and China should specialize in manufactures. The global output for each good doubles compared to autarky.
    • Trade allows countries to consume outside their PPF through specialization and exchange.
    • Example: Through trade, the US and China can both consume 800 unites of services and manufactures, compared to 533 1/3 in autarky.
    • For trade to occur, the price of the traded goods must fall between the opportunity costs of producing them.

    Production Possibilities Frontier

    • Depicts the maximum possible output of two goods an economy can produce with fixed resources and technology.
    • Can produce any combination of two goods (e.g., manufactures and services) that satisfies the PPF equation.
    • Slope: Represents the marginal technical rate of substitution (MRTS), which is the opportunity cost of producing one good in terms of the other.
    • Intercept: Represents the maximum output of one good when all resources are allocated to its production.

    Absolute vs. Comparative Advantage

    • Absolute advantage: A country can produce more of a good than another country with the same amount of input.
    • Comparative advantage: A country can produce a good at a lower opportunity cost than another country.
    • Comparative advantage is the basis for international trade because countries can specialize in producing goods where they have a lower opportunity cost.

    Ricardian Model

    • Specialisation: Countries should specialize in producing the goods where they have a comparative advantage and trade with other countries to obtain goods where they are less efficient.
    • International Trade: Trade allows countries to consume beyond their own PPF, increasing overall welfare.
    • Trade Price: The price of goods traded must be between the opportunity costs of the two countries for trade to be mutually beneficial.

    The Ricardian Model: No Trade (Autarky)

    • Each country produces and consumes the same amount of both goods.
    • Global production is limited because each country produces everything, even if they are inefficient in producing one.

    The Ricardian Model: Free Trade

    • Countries specialize in the goods they have a comparative advantage in.
    • Global production increases because each country is more efficient in producing its specialized good.
    • Global consumption increases as countries can trade and access more goods and services.
