Quiz: International Trade and Globalization

Test your understanding of why countries trade, comparative advantage, and trade policy debates.

1. What is comparative advantage?

  1. The ability to produce a good using fewer resources than another country
  2. The ability to produce a good at a lower opportunity cost than another country
  3. Having the largest economy in the world
  4. Being able to export more goods than you import
Show Answer

The correct answer is B. Comparative advantage means a country can produce a good at a lower opportunity cost than another country. Even if one country is better at producing everything (absolute advantage), both countries benefit when each specializes in what they produce at the lowest opportunity cost. This is the fundamental principle behind why trade makes both parties better off.

2. If the United States exports soybeans to Japan and imports electronics from Japan, both countries benefit because of what economic principle?

  1. Price ceilings keep costs low
  2. Government subsidies make trade profitable
  3. Specialization based on comparative advantage increases total output
  4. Both countries have identical resources
Show Answer

The correct answer is C. When countries specialize in producing goods where they have a comparative advantage and then trade, total global output increases. The US can produce soybeans at a lower opportunity cost, while Japan can produce electronics more efficiently. By specializing and trading, both countries end up with more goods than if each tried to produce everything domestically.

3. A tariff is best defined as what?

  1. A tax on imported goods that raises their price in the domestic market
  2. A subsidy given to domestic exporters
  3. A limit on the quantity of goods that can be imported
  4. A trade agreement between two countries
Show Answer

The correct answer is A. A tariff is a tax imposed on imported goods, raising their price and making domestic products relatively cheaper. Tariffs protect domestic industries from foreign competition but also raise costs for consumers. While tariffs may save jobs in protected industries, they reduce consumer purchasing power and can provoke retaliatory tariffs from trading partners.

4. When a country's currency appreciates (increases in value relative to other currencies), what happens to its exports and imports?

  1. Exports become cheaper and imports become more expensive
  2. Both exports and imports become cheaper
  3. Both exports and imports become more expensive
  4. Exports become more expensive abroad and imports become cheaper domestically
Show Answer

The correct answer is D. When a currency appreciates, it buys more foreign currency. This makes foreign goods cheaper for domestic buyers (imports increase) but makes domestic goods more expensive for foreign buyers (exports decrease). A stronger dollar means American tourists get more for their money abroad, but American manufacturers find it harder to sell overseas because their products cost more in foreign currencies.

5. A trade deficit means a country is doing what?

  1. Exporting more goods than it imports
  2. Importing more goods than it exports
  3. Refusing to trade with other countries
  4. Running a government budget surplus
Show Answer

The correct answer is B. A trade deficit occurs when a country's imports exceed its exports. The US has run a trade deficit for decades, meaning Americans buy more from other countries than other countries buy from the US. A trade deficit is not necessarily bad: it can mean consumers have access to affordable goods, and foreign investment flows into the country to finance the difference.

6. Which argument do protectionists most commonly use to justify restricting free trade?

  1. Free trade always reduces a country's GDP
  2. Imports improve consumer choice and lower prices
  3. Trade restrictions protect domestic jobs and industries from foreign competition
  4. All countries have identical comparative advantages
Show Answer

The correct answer is C. Protectionists argue that trade restrictions shield domestic workers and industries from competition with lower-wage countries. While trade does create winners (consumers, export industries) and losers (workers in import-competing industries), economists generally find that the overall gains from trade exceed the losses. The challenge is helping displaced workers transition to new opportunities.

7. Why do most economists support free trade despite its downsides?

  1. Free trade eliminates all unemployment
  2. Free trade benefits every individual equally
  3. Free trade increases total economic output by allowing specialization based on comparative advantage
  4. Free trade is required by international law
Show Answer

The correct answer is C. Economists support free trade because specialization according to comparative advantage increases total production, lowers prices, and expands consumer choice. However, economists also acknowledge that trade creates losers (displaced workers) alongside winners (consumers, export industries). The consensus is that the gains outweigh the losses, but policies should help those who are negatively affected.

8. Globalization has connected economies worldwide. Which of the following is a legitimate concern about globalization that economists take seriously?

  1. Globalization has no benefits for any country
  2. Workers in developed countries may face job displacement when manufacturing moves to lower-wage nations
  3. International trade always reduces a country's standard of living
  4. Globalization only benefits large corporations and never helps consumers
Show Answer

The correct answer is B. While globalization increases total economic welfare, its benefits are not evenly distributed. Workers in industries that face foreign competition may lose jobs or see wages decline. Manufacturing workers in developed countries have been particularly affected as production shifted to countries with lower labor costs. This is why trade policy debates focus on how to help displaced workers, not just overall efficiency.

9. Country A can produce 100 computers or 200 shirts. Country B can produce 50 computers or 300 shirts. Which country has a comparative advantage in producing shirts?

  1. Country A, because it is larger
  2. Country B, because the opportunity cost of making shirts is lower
  3. Country A, because it can make more computers
  4. Neither country has an advantage
Show Answer

The correct answer is B. Country B's opportunity cost of one shirt is 1/6 of a computer (50/300), while Country A's opportunity cost of one shirt is 1/2 of a computer (100/200). Since Country B gives up fewer computers per shirt, it has the comparative advantage in shirts. Country A has the comparative advantage in computers (giving up 2 shirts per computer vs. 6 for Country B).

10. Exchange rates between currencies are determined primarily by what in most modern economies?

  1. International agreements between governments
  2. The price of gold
  3. The United Nations
  4. Supply and demand for currencies in foreign exchange markets
Show Answer

The correct answer is D. In floating exchange rate systems, currency values are determined by supply and demand in foreign exchange markets. When demand for a currency increases (due to strong exports, foreign investment, or higher interest rates), the currency appreciates. When demand decreases, it depreciates. While central banks sometimes intervene, most major currencies float freely based on market forces.
