International Trade and Comparative Advantage

Consider two countries, Country A and Country B, both capable of producing Goods X and Y. Country A has an absolute advantage in producing both goods. Why might these countries still benefit from trading with each other?

Refer to the comparative advantage output table below:

Country	Good X Output	Good Y Output	Opportunity Cost of X	Opportunity Cost of Y
Country A	100	80	0.8Y per X	1.25X per Y
Country B	60	90	1.5Y per X	0.67X per Y

Based on the table, why might Country A and Country B choose to trade?

• To achieve a higher total output through specialization and trade.

• To avoid producing goods where its opportunity cost is higher.

• To increase overall economic efficiency and gains for all countries.

• To reduce the need for domestic production of all goods.

In what ways can trade allow countries to consume beyond their own PPC?

• Specialization in goods with comparative advantage.

• Exporting specialized goods in exchange for other goods.

• Achieving expanded consumption through better trade rates.

• Producing all goods domestically without trade.

How can changes in opportunity cost (due to technology, resources, or other factors) affect international trade relationships?

• Technology reducing labor needed for production.

• Discovery of large, accessible natural resources.

• Government investment in education and skills.

• Rapid increase in wages affecting labor-intensive goods.

Products sold to other countries

• Currency
• Import
• Export
• International trade

In the scenario where the Attorney is faster at both legal work and typing, the concept of opportunity cost is central. What is the Attorney's opportunity cost of spending one hour typing documents?

• The cost of the Secretary's salary for one hour.

• The total amount of time spent typing the documents

• The value of the legal services that could have been billed during that hour

• The total number of documents the Secretary could have typed in that hour.

Why does the law firm benefit most when the Attorney specializes in legal work and delegates the typing to the Secretary?

• The Attorney's typing speed is too slow to be profitable.

• The law firm saves money by paying the Secretary a lower wage.

• Specialization maximizes the firm's total output (billable hours) because the Attorney is working where their opportunity cost is lowest.

• Secretary has better typing skills, making the final documents of higher quality.

For any trade, whether between individuals (Attorney/Secretary) or countries (US/China), to be mutually beneficial, the terms of trade (the rate at which one good is exchanged for another) must be better than the domestic opportunity cost for both parties.

• Opportunity Cost (Domestic Price): The opportunity cost represents the domestic price of a good. If a country can trade for a good at a price lower than its own domestic opportunity cost of producing that good, it gains.

• The Gain: Both the Attorney and the Secretary gain because they can obtain the service they are not specializing in (typing for the Attorney, legal work for the Secretary) at a lower "price" than it would cost them to produce it themselves.

If the Attorney and the Secretary trade (the Attorney provides legal services, the Secretary provides typing), which condition ensures that this "trade" is mutually beneficial?

• The Attorney must be paid for the time they spend supervising the Secretary.

• The agreed-upon exchange rate (or wage structure) must fall between the Attorney's and the Secretary's opportunity costs.

• The Secretary must eventually become faster than the Attorney at both tasks.

What does this example illustrate about the relationship between absolute advantage and trade?

• Absolute advantage is the only factor that determines profitable trade

• A country (or person) with an absolute advantage in all goods will never benefit from trade

• Trade is based on comparative advantage (opportunity cost), meaning a country should specialize even if it is better at producing everything.

• The country with the absolute advantage should always produce both goods itself.

The United States has an absolute advantage in producing both high-tech microchips and simple consumer goods. China has a lower cost for producing simple consumer goods. What is the economic rationale that still makes trade between these two countries beneficial?

• The United States must import to maintain friendly international relations

• Trade is determined by comparative advantage, where each country specializes in the good with the lowest opportunity cost.

• China has a scarcity of the necessary resources to produce high-tech goods.

• Absolute advantage is only relevant for trade between developing nations.

China has an abundance of labor, resulting in lower wages compared to the US. Which type of production is China most likely to have a comparative advantage in, and why?

• Capital-intensive goods, because capital is abundant.

• Natural resource extraction, because it has more land area than the US.

• Labor-intensive simple consumer goods, because its opportunity cost is lower due to the abundance of cheap labor
