This module outlines the main types of protectionist policies governments use to restrict international trade and shield domestic industries. You will learn the core features, operations, and key differences between tariff and non-tariff barriers.

**Prerequisites:** [Gains from international trade](https://www.owlsprep.com/study/cie-9708-u7-gains-from-trade/); [Supply and demand analysis of international trade](https://www.owlsprep.com/study/cie-9708-u7-trade-equilibrium/)

## Learning objectives

- Distinguish between tariff and non-tariff protectionist policies
- Explain how each protectionist measure operates
- Identify examples of different protectionist policies in context
- Compare the core features of common protectionist tools

## Tariffs

**Tariff** — A tax imposed on imported goods when they enter a country, designed to raise their price relative to domestically produced goods

*Notation:* Ad valorem: percentage of import price; Specific: fixed charge per unit

*Example:* 15% ad valorem tariff on imported textiles

Tariffs are the most transparent and widely used form of protectionism. They achieve two goals for governments: raising government revenue, and making domestic producers more competitive against cheaper imports by increasing import costs.

**Worked example:** A country imports 100,000 bottles of wine at a world price of $10 each. The government imposes a 20% ad valorem tariff. Imports fall to 60,000 bottles after the tariff. Calculate the new government revenue from the tariff.

1. First, calculate the size of the tariff per bottle:
2. $$\text{Tariff per bottle} = 20\% \times 10 = \$2$$
3. Government revenue equals the tariff per unit multiplied by the new volume of imports:
4. $$\text{Total Revenue} = 2 \times 60,000 = \$120,000$$

## Quotas

**Quota** — A binding legal limit on the quantity of a good that can be imported into a country over a set period of time

*Example:* An annual limit of 100,000 imported passenger cars

Unlike tariffs, quotas do not automatically generate government revenue. The extra profit from restricted imports, called quota rent, accrues to whoever holds the right to import the restricted good. If the government auctions import licenses, it captures the quota rent as revenue. If licenses are given away for free, rent goes to license holders.

**Worked example:** The world price of bananas is $0.20 per kg. A country imposes a quota of 5 million kg, which raises the domestic price to $0.35 per kg. Calculate the total quota rent.

1. Find the difference between the domestic price and world price per kg:
2. $$\text{Rent per kg} = 0.35 - 0.20 = \$0.15$$
3. Multiply by the total quota volume to get total quota rent:
4. $$\text{Total Quota Rent} = 0.15 \times 5,000,000 = \$750,000$$

> When asked to compare tariffs and quotas, always mention that tariffs generate government revenue while quotas generate quota rent for license holders.

## Domestic Subsidies

**Domestic subsidy** — A per-unit payment from the government to domestic producers that lowers their production costs, allowing them to compete with cheaper imports

*Example:* Agricultural subsidies paid to domestic farmers to compete with cheaper imported food

Subsidies are considered a less distortionary form of protection than tariffs or quotas because they do not directly raise prices for consumers. However, they impose a direct cost on the government (and thus taxpayers) and can support inefficient domestic producers that would otherwise exit the market.

**Worked example:** Domestic producers of dairy need $3 per litre to cover costs, while the world price of dairy is $2.50 per litre. How can a subsidy make domestic producers competitive without raising consumer prices?

1. The government pays a subsidy of $0.50 per litre to domestic dairy producers.
2. Domestic producers can sell their dairy at the world price of $2.50 per litre to consumers, and still receive a total of $3 per litre (
$2.50 from consumers + $0.50 subsidy), covering their costs.
3. Consumers pay the same low world price as before, but domestic producers gain protection from cheaper imports.

## Non-Tariff Barriers

Non-tariff barriers are protectionist measures that do not fit into the categories of tariffs, quotas, or subsidies. They are often less transparent than traditional protectionist tools, and can be used to quietly restrict imports without violating formal trade agreements.

- **Embargoes**: Complete bans on imports from a specific country, usually for political reasons
- **Administrative barriers**: Excessive red tape, customs delays, or paperwork requirements that increase import costs
- **Product standards**: Strict safety, labeling, or environmental rules that disproportionately disadvantage foreign producers
- **Local content requirements**: Rules that require a certain percentage of a product to be made domestically to be sold in the country

**Worked example:** A country requires all imported food to undergo 3 weeks of additional safety testing that is not required for domestic food. What type of protectionist policy is this, and how does it work?

1. This is an administrative non-tariff barrier.
2. The additional testing increases the time and cost for foreign producers to export to the country, raising the final price of imported food and reducing import volumes.
3. Domestic producers face no extra costs, so they become more competitive relative to imports, achieving the goal of protection.

> CIE frequently asks for 2/3 marks to name examples of non-tariff barriers, so memorise at least 3 different examples for exam day.

## Common pitfalls

- **Wrong:** Assuming quotas always generate government revenue like tariffs
  - Why it fails: Quotas only generate government revenue if the government auctions import licenses, otherwise quota rent goes to license holders
  - Correct: Explicitly state that quota revenue depends on how import licenses are allocated, rather than assuming automatic government revenue
- **Wrong:** Claiming domestic subsidies never harm consumers
  - Why it fails: While subsidies do not directly raise consumer prices, they are funded by taxpayer money, so there is an indirect cost to consumers
  - Correct: Distinguish between the direct effect (no consumer price rise) and indirect cost (taxpayer burden) of subsidies
- **Wrong:** Calling all protectionist measures tariffs
  - Why it fails: Exams frequently test knowledge of non-tariff barriers, which are a separate category of protectionism
  - Correct: Categorise each policy correctly when answering questions, and always give examples of non-tariff barriers when asked
- **Wrong:** Thinking protectionism only applies to trade in goods
  - Why it fails: Protectionist policies are also commonly used to restrict trade in services and foreign investment
  - Correct: Recognise that policies like limits on foreign banks operating in a country are also protectionist

## Cheatsheet

| Policy Type | Core Mechanism | Key Outcome |
| --- | --- | --- |
| Tariff | Tax on imported goods | Raises government revenue, increases domestic price |
| Quota | Quantitative limit on imports | Creates quota rent, raises domestic price |
| Domestic Subsidy | Payment to domestic producers | No direct consumer price rise, costs government |
| Embargo | Complete ban on imports | Stops all trade, usually political |
| Product Standard | Regulation for imported goods | Non-transparent protection, raises import costs |

## What's next

Understanding the different types of protectionist policies is the foundation for analysing their economic impacts and evaluating the arguments for and against protectionism, topics that are heavily tested in both CIE Paper 2 and Paper 3. Next, you will explore how each protectionist policy affects consumers, producers, government, and overall economic welfare, before moving on to study the role of trade agreements and the World Trade Organization in reducing global trade barriers. Mastery of this sub-topic is essential for constructing well-reasoned evaluations of trade policy in exam essays.
