Protectionism
Protectionism: build the core model, apply it to evidence and qualify conclusions where outcomes depend on context.
Section 6.2 · Protectionism
9708 section 6.2; AS Level. Checked against Cambridge's 2026–2028 Version 2 (latest version published December 2025) and 2029 Version 1 (published September 2026). Cambridge states that neither version has significant changes affecting teaching. Always follow the syllabus for the candidate's examination year.
Before you begin
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which policy directly limits the quantity of a product that may be imported?
What you will learn
- Define protectionism
- Analyse tariffs, quotas, subsidies, embargoes and administrative barriers
- Evaluate arguments for and against protection
Core model and terms
Protectionism restricts or alters international trade to favour domestic producers or pursue another policy aim. Tools include tariffs, import quotas, export subsidies, embargoes and administrative burdens. Their effects differ: a tariff raises the domestic price of imports, a quota limits quantity, and an export subsidy supports domestic exporters.
Apply and evaluate
Arguments include infant-industry learning, strategic security, employment or responses to unfair competition. Costs can include higher consumer prices, less choice, inefficient resource use and retaliation. Assess who benefits, how long support lasts, the market response and whether a less costly policy could meet the same objective.
Pause and explain
Which statement best applies protectionism?
Worked example
A tariff raises the price of an imported product while domestic supply is limited. Trace a likely effect on consumers and domestic firms.
Show the worked solution
- The tariff raises the landed price of imports
- Consumers may pay more or buy less
- Domestic producers may gain sales if they can supply substitutes
Answer The tariff raises the landed price of imports → Consumers may pay more or buy less → Domestic producers may gain sales if they can supply substitutes

A tariff raises the price of an imported product while domestic supply is limited. Trace a likely effect on consumers and domestic firms.
Give me a hint
Follow the import price to domestic demand and competing suppliers.
Compare my reasoning
- The tariff raises the landed price of imports
- Consumers may pay more or buy less
- Domestic producers may gain sales if they can supply substitutes

How does an import quota differ from a tariff?
Give me a hint
Compare a quantity limit with a tax on imported units.
Compare my reasoning
- A quota caps the amount imported
- A tariff adds a tax per imported unit
- Both can restrict trade, but price and quota rents can differ

A temporary tariff protects a new industry. Give one possible benefit and one test for whether the policy is justified.
Give me a hint
Consider learning gains and a clear review condition.
Compare my reasoning
- Protection may give firms time to develop skills or scale
- Consumers and downstream firms may face higher costs
- Evidence should show learning gains that can make later competitiveness plausible

A trading partner retaliates after an embargo. Explain why the policy’s national effect can be broader than the targeted imports.
Give me a hint
Trace the response through exports and supply chains.
Compare my reasoning
- The partner can restrict the country’s exports
- Exporters lose market access and income
- Input shortages or wider trade conflict can raise costs beyond the original product

Common mistakes
- Listing a protectionist argument without identifying its beneficiaries, consumer costs, possible retaliation or review conditions.
What can you explain now?
Which policy directly limits the quantity of a product that may be imported?
Compare with the explanation
An import quota
A quota specifies a maximum import quantity.
