Think of international trade like a giant classroom exchange program. Students (countries) swap their favourite books (goods) and ideas (services) to learn new skills and get better books. Trade policy decides how easy or hard that swapping is.
Tariffs – a tax on imported goods.
📊 Example: A 20% tariff on imported cars raises their price, making domestic cars cheaper by comparison.
Quotas – limits on the quantity of a good that can be imported.
📦 Example: Only 10,000 units of a popular smartphone can enter the market each year.
Export Subsidies – government payments to domestic exporters.
💸 Example: Farmers receive a subsidy that lowers the price of their wheat on the world market.
Currency Manipulation – adjusting the exchange rate to make exports cheaper.
💱 Example: A country devalues its currency so its goods become cheaper abroad.
Trade policies can help one objective but may hurt another. The table below shows typical outcomes.
| Policy | Growth | Balance of Payments | Price Stability | Competitiveness |
|---|---|---|---|---|
| Tariffs | ↑ (short‑term) | ↑ (imports ↓) | ↓ (imported goods more expensive) | ↑ (domestic firms protected) |
| Quotas | ↑ (short‑term) | ↑ (imports ↓) | ↓ (price spikes) | ↑ (domestic firms protected) |
| Export Subsidies | ↑ (exports ↑) | ↑ (balance ↓) | ↓ (domestic prices may fall) | ↑ (competitiveness ↑) |
| Currency Manipulation | ↑ (exports cheaper) | ↑ (balance ↓) | ↓ (imported goods more expensive) | ↑ (competitiveness ↑) |
Tip 1: Remember the trade‑off triangle – growth, balance, and price stability often clash.
Tip 2: Use the formula for the trade balance: \$TB = X - M\$ where \$X\$ is exports and \$M\$ is imports.
Tip 3: In essay questions, structure your answer with introduction → policy options → effectiveness → conclusion.
