Key Concepts Breakdown
1 Comparative Advantage
Comparative advantage exists when a country can produce a good at a lower opportunity cost than another country. Countries should specialize in goods where they have the lowest opportunity cost and trade for the rest. This leads to greater total output and mutual gains from trade.
Key Points
- Comparative advantage is about opportunity cost, NOT absolute productivity
- A country can have a comparative advantage even if it is less efficient at producing everything
- Specialization and trade based on comparative advantage increases total world output
- To find comparative advantage, compare the opportunity cost of each good between countries
Country A can produce 10 cars OR 20 tons of wheat per day. Country B can produce 4 cars OR 12 tons of wheat per day. Which country has the comparative advantage in cars?
Country A's opportunity cost of 1 car is 2 tons of wheat (20/10). Country B's opportunity cost of 1 car is 3 tons of wheat (12/4). Since Country A gives up less wheat per car, Country A has the comparative advantage in cars. Country B should specialize in wheat, where its opportunity cost (1/3 car) is lower than Country A's (1/2 car).
2 Trade Barriers
Trade barriers are government policies that restrict imports, including tariffs (taxes on imports), quotas (limits on import quantity), and subsidies (payments to domestic producers). Students must know the effects of each barrier on price, quantity, consumer surplus, producer surplus, and government revenue. Tariffs and quotas raise domestic prices and protect domestic producers at the expense of consumers.
Key Points
- A tariff raises the price consumers pay and generates government revenue; a quota does not generate revenue
- Both tariffs and quotas reduce imports, lower consumer surplus, and raise producer surplus
- Net welfare loss (deadweight loss) occurs because resources are misallocated away from efficient foreign producers
- Subsidies to domestic producers lower their costs, increase domestic output, but can lead to overproduction and trade disputes
The domestic price of steel is $400/ton without trade. The world price is $300/ton. The government imposes a $50/ton tariff. What is the new domestic price, and who benefits and who loses?
The new domestic price becomes $350/ton (world price + tariff). Domestic steel producers benefit because they now receive a higher price, expanding their output. Consumers lose because they pay $350 instead of $300. The government collects $50 per ton of steel imported as revenue, but there is still a net deadweight loss to society from reduced trade.
3 Exchange Rates
An exchange rate is the price of one currency expressed in terms of another. When a currency appreciates (rises in value), imports become cheaper and exports become more expensive for foreign buyers. When a currency depreciates (falls in value), exports become cheaper abroad and imports become more expensive domestically.
Key Points
- Currency appreciation makes exports MORE expensive and imports CHEAPER — hurts exporters, helps importers
- Currency depreciation makes exports CHEAPER and imports MORE expensive — helps exporters, hurts importers
- Higher interest rates attract foreign investment, increasing demand for a currency and causing it to appreciate
- A trade deficit can put downward pressure on a currency because domestic residents must sell their currency to buy foreign goods
The exchange rate is 1 USD = 0.90 EUR. A US company sells a product for $100. If the dollar appreciates to 1 USD = 1.10 EUR, what happens to the euro price of the US product for European buyers?
Originally, the $100 product cost European buyers 90 EUR (100 × 0.90). After the dollar appreciates, the same product costs 110 EUR (100 × 1.10). This makes the US product more expensive for Europeans, so US exports to Europe will likely fall. This illustrates why a strong dollar can hurt US export industries.
