Suppose that country $A$ and country $B$ both produce wine and cheese. Country $A$ has 800 units of available labor, while country $B$ has 600 units. Prior to trade, country $A$ consumes 40 pounds of cheese and 8 bottles of wine, and country $B$ consumes 30 pounds of cheese and 10 bottles of wine. a. Which country has a comparative advantage in the production of each good? Explain. b. Determine the production possibilities curve for each country, both graphically and algebraically. (Label the pretrade production point $P T$ and the post-trade point $P .)$ c. Given that 36 pounds of cheese and 9 bottles of wine are traded, label the post-trade consumption point $C$ d. Prove that both countries have gained from trade. e. What is the slope of the price line at which trade occurs?

Key Concepts

Comparative Advantage

Comparative advantage is the economic principle that describes how an entity should specialize in producing goods for which it has a lower opportunity cost compared to others, rather than absolute efficiency. This concept underpins the benefits of trade, as each country or producer will benefit by exporting products in which it holds a relative efficiency, even if one country is overall more productive in all goods.

Production Possibilities Frontier (PPF)

The production possibilities frontier is a curve that shows all maximum possible output combinations of two goods that an economy can produce with available resources and technology while operating efficiently. It illustrates the trade-offs and opportunity costs inherent in reallocating resources between different goods, and any point on the frontier represents efficient production levels.

Gains from Trade

Gains from trade refer to the improvements in overall welfare that result when countries specialize in the production of goods in which they have a comparative advantage and then exchange them. By trading, countries can consume a combination of goods that would be unattainable if they relied solely on domestic production, effectively moving beyond their individual production possibilities frontiers.

Terms of Trade and Price Line Slope

The terms of trade are defined by the rate at which one good is exchanged for another in international markets, and this is reflected in the slope of the price line. The price line indicates the relative prices or opportunity costs of the traded goods, and its slope determines how much of one good a country must give up to obtain an additional unit of the other through trade.
