This lesson focuses on Protectionism Explained: examine tariffs, quotas and the arguments for and against them.

Definition: Protectionism Explained

Examine tariffs, quotas and the arguments for and against them.

Key ideas

Protectionism versus free trade

Tariffs and quotas shield domestic jobs and infant industries and can protect national security, but they raise consumer prices, invite retaliation and shelter inefficiency. Globalisation has lifted millions from poverty through trade-led growth, yet created losers in declining industries — hence demands for retraining and compensation.

The gains from trade

Ricardo showed that if Portugal gives up less wine to make cloth than England does, both gain by specialising and trading — even if Portugal is better at both. Trade enlarges both nations' consumption possibilities, though the gains may be unevenly shared within each country.

Key term — tariff: A tax on imports that raises their price, protecting domestic producers but hurting consumers.

Worked example: Protectionism Explained

Answer: For: protects domestic jobs and infant industries. Against: raises consumer prices and risks retaliation.

Common mistakes
  • Thinking exports are good and imports bad Imports give consumers choice and lower prices and supply inputs for exporters — a surplus is not automatically better than a deficit.
  • Confusing depreciation with devaluation Depreciation is a market-driven fall in a floating currency; devaluation is a deliberate cut in a fixed exchange rate.

Practice

What is a quota?
A limit, not a tax.

A physical limit on the quantity of a good that may be imported.

State Ricardo's principle of comparative advantage.
Think opportunity cost.

Countries gain by specialising in goods they produce at the lowest opportunity cost, then trading.

If £1 = $1.27, how many dollars does £50 buy?
Multiply.

$63.50 (50 × 1.27).

The pound depreciates. What happens to the price of UK exports abroad?
Cheaper or dearer?

They become cheaper in foreign currency, boosting demand for them.
