1What does the principle of comparative advantage state about international trade?
A.A country gains from trade by specializing in producing goods with a lower opportunity cost.
B.A country should produce all goods it can manufacture faster than any other country.
C.A country should only trade with nations that possess identical resource endowments.
D.A country maximizes economic welfare by imposing tariffs to protect domestic industries.
Explanation: Comparative advantage occurs when a nation can produce a good or service at a lower opportunity cost than another nation. Specializing according to comparative advantage allows total global output and consumption to increase through international trade.
2Country A can produce either 40 units of Wheat or 20 units of Cloth per hour. Country B can produce either 30 units of Wheat or 15 units of Cloth per hour. Which statement correctly identifies their opportunity costs?
A.Country A has a lower opportunity cost of producing Wheat than Country B.
B.Both countries have the exact same opportunity cost of producing Cloth (2 units of Wheat).
C.Country B has a lower opportunity cost of producing Cloth than Country A.
D.Country A has a comparative advantage in Cloth and Country B has a comparative advantage in Wheat.
Explanation: For Country A, the opportunity cost of 1 unit of Cloth is 40/20 = 2 units of Wheat. For Country B, the opportunity cost of 1 unit of Cloth is 30/15 = 2 units of Wheat. Because their opportunity costs are identical, neither country holds a comparative advantage over the other.
3Absolute advantage is best defined as a nation's ability to:
A.Produce a good at a lower opportunity cost than any competitor nation.
B.Export more goods than it imports, creating a constant trade surplus.
C.Maintain fixed exchange rates relative to its major trading partners.
D.Produce a greater quantity of a good using the same inputs than another nation.
Explanation: Absolute advantage refers to the capability of an economy to produce a specific good or service more efficiently (using fewer resources or producing higher output per input unit) than another economy.
4When a government imposes a tariff on an imported good, what is the immediate effect on the domestic market?
A.Domestic price falls, domestic production increases, and imports increase.
B.Domestic price rises, domestic production decreases, and imports increase.
C.Domestic price rises, domestic production increases, and imports decrease.
D.Domestic price falls, domestic production decreases, and government tax revenue decreases.
Explanation: A tariff is a tax on imports that elevates the domestic price of imported goods up to the world price plus tariff. This higher price encourages domestic producers to expand production while domestic consumption contracts, leading to a decline in import volume.
5Which welfare area on a standard tariff graph represents deadweight loss caused by the reduction in consumer surplus that is not recovered by producer surplus or government tariff revenue?
A.The two production and consumption efficiency loss triangles.
B.The producer surplus rectangle.
C.The government tax revenue rectangle.
D.The total area under the domestic demand curve.
Explanation: Deadweight loss consists of the production distortion triangle (inefficient domestic producers producing output that foreign producers could make at lower cost) and the consumption distortion triangle (loss of consumer utility due to restricted consumption).
6How does a domestic producer subsidy differ from an import tariff?
A.Subsidies increase domestic consumer prices, whereas tariffs reduce them.
B.Subsidies directly increase government tax revenue, whereas tariffs require government spending.
C.Subsidies are prohibited under all circumstances by foreign trade agreements.
D.Subsidies increase domestic production without raising the price paid by domestic consumers.
Explanation: A production subsidy reduces domestic producers' marginal costs, shifting their supply curve down and allowing them to expand output at the world price without inflating the market price paid by consumers.
7What is a primary economic distinction between an import quota and an import tariff?
A.An import quota generates revenue for the importing government, while a tariff generates quota rents for foreign exporters.
B.An import quota increases total consumer surplus, while a tariff eliminates producer surplus.
C.An import quota fixes the physical quantity of imports allowed, while a tariff raises the import price via tax.
D.An import quota leads to zero deadweight loss compared to a tariff.
Explanation: An import quota places a direct physical limit on the volume of a good imported, whereas a tariff is a price-based tax. Quotas assign revenue (quota rents) to license holders rather than automatically raising government revenue like tariffs.
8If Australia's Export Price Index rises from 100 to 110 while its Import Price Index increases from 100 to 105, what is the new Terms of Trade index?
A.95.45
B.105.00
C.104.76
D.115.50
Explanation: Terms of Trade (TOT) Index = (Export Price Index / Import Price Index) * 100 = (110 / 105) * 100 = 104.76.
9A favorable movement (increase) in Australia's Terms of Trade index implies that:
A.Australia must export a greater physical volume of commodities to pay for the same imports.
B.Export prices have fallen significantly faster than import prices.
C.Australia can purchase a larger volume of imports for a given volume of exports.
D.Australia's trade balance will automatically register a structural budget deficit.
Explanation: An improvement in the Terms of Trade means export prices have risen relative to import prices. This increases Australia's national purchasing power, allowing more imports to be purchased per unit of exports.
10Which factor is most likely to cause a major increase in Australia's Terms of Trade?
A.A sharp rise in global oil prices imported by Australian fuel retailers.
B.A surge in global demand for Australian iron ore and liquefied natural gas (LNG).
C.A global recession reducing commodity demand across Asian manufacturing hubs.
D.An increase in foreign tariff rates placed on Australian agricultural exports.
Explanation: A boom in global demand for Australia's major commodity exports (like iron ore and LNG) drives up export prices, expanding the numerator of the Terms of Trade ratio and raising the index.
