KEY POINTS
Protectionism occurs when a government restricts international trade to protect domestic businesses or industries.
The main methods include tariffs, import quotas, domestic subsidies and government legislation or regulation.
A tariff is a tax on imports, making imported goods more expensive.
An import quota limits the quantity of a product that can be imported.
Domestic subsidies reduce costs for home producers, making them more competitive against foreign rivals.
Government legislation and regulation can make it harder, slower or more expensive for overseas firms to sell in a market.
Protectionism may protect jobs, infant industries and strategic sectors, but it can also raise prices and reduce consumer choice.
Strong exam answers judge the impact on different businesses, including domestic producers, exporters, importers and consumers.
KEY DEFINITION
Protectionism
Protectionism is the use of government policies to restrict international trade, usually to protect domestic businesses or industries from overseas competition.
Main Explanation
Protectionism occurs when a government restricts international trade in order to protect domestic businesses, jobs or industries from overseas competition. It is the opposite of open trade, where goods and services can move more freely between countries.
The main forms of protectionism in A Level Business are tariffs, import quotas, domestic subsidies and government legislation or regulation. These methods affect businesses in different ways, so strong answers should not treat all trade barriers as identical.
A tariff is a tax placed on imported goods. This increases the cost of imports and may make overseas products more expensive for customers. If imported goods become more expensive, domestic producers may find it easier to compete because their products become relatively cheaper.
However, tariffs can create problems for businesses that rely on imported raw materials, components or finished goods. If a business imports stock or parts from overseas, tariffs may increase its costs. The business may then have to raise prices, accept lower profit margins or find alternative suppliers.
An import quota is a limit on the quantity of a product that can be imported into a country. This can protect domestic producers by reducing the supply of foreign goods in the market. If fewer imports are available, domestic businesses may gain more sales or have more pricing power.
However, quotas can reduce consumer choice and may increase prices if supply is restricted. They can also create problems for businesses that depend on imported goods. For example, a retailer may struggle to access enough stock, or a manufacturer may struggle to source enough components.
Domestic subsidies are financial support given by a government to businesses within its own country. Subsidies can reduce costs for domestic producers, allowing them to lower prices, invest, survive difficult conditions or compete more effectively against foreign firms.
Subsidies can help protect jobs and support important industries. However, they can also distort competition because subsidised firms may have an artificial cost advantage. This may lead to tension with other countries and could trigger retaliatory measures.
Government legislation and regulation can also act as trade barriers. These may include product standards, safety rules, environmental requirements, labelling rules, licensing requirements or administrative procedures. Some rules may be justified for safety or quality reasons, but they can also make it harder for foreign businesses to enter the market.
Protectionism may be used to protect infant industries. An infant industry is a new or developing industry that may need time to grow before it can compete with established overseas firms. Temporary protection may allow the industry to build scale, skills and productivity.
Governments may also protect strategic industries. These are industries considered important for national security, employment, infrastructure or economic resilience. Examples could include food production, energy, defence, steel, technology or transport.
However, protectionism can create disadvantages. Consumers may face higher prices and less choice. Domestic businesses may become less efficient if they are shielded from international competition. Overseas countries may retaliate with their own trade barriers, making it harder for exporters to sell abroad.
The impact of protectionism depends on the business context. A domestic producer competing against cheaper imports may benefit from tariffs or quotas. An exporter may suffer if other countries retaliate. A manufacturer using imported components may face higher costs. A consumer-facing business may find demand falls if prices rise.
Overall, protectionism is not simply good or bad. It can protect domestic industries and jobs in the short term, but it can also reduce efficiency, raise prices and create trade conflict. Strong exam answers should judge who benefits, who loses, and whether the protection supports long-term competitiveness.
✎ EXAMINER TIP
When answering questions on protectionism, identify the specific trade barrier first. A tariff, quota, subsidy and regulation all work differently, so the impact on costs, prices, supply, demand and competitiveness will also be different.
KEY FORMULAS(s)
Profit and Profitability Formulas
These key formulas help you calculate different profit measures and profitability ratios used in business.
Gross Profit
Gross profit = Revenue − Cost of sales
The profit made after deducting direct costs.
!
Remember: profit shows how much money has been made, while profitability shows how efficiently revenue is being turned into profit.
DATA TABLE
Income Statement for North Coast Coffee Ltd
This statement shows how revenue is converted into gross profit, operating profit and net profit.

Net profit is the final profit remaining after all costs and expenses have been deducted from revenue.
How Protectionism Affects Business Competitiveness

This chart shows how protectionism can create different impact chains for domestic producers, importers, exporters and consumers.
WORKED EXAMPLE
Worked Example: North Coast Coffee
How many coffees must be sold to break even?
Fixed Costs
£1,800
equity + long-term debt
Break-even output = Fixed costs ÷ Contribution per unit
Contribution per unit = Selling price − Variable cost
£3.50 − £1.10 = £2.40
1
Step 1: Calculate contribution
£3.50 − £1.10 = £2.40
Contribution per unit is the amount each coffee contributes towards fixed costs.
BREAK-EVEN OUTPUT:
750 coffees per month
EXAM TIP
Always explain what the number means for the business. Do not just calculate the break-even point.

Methods of Protectionism

This diagram shows the main methods of protectionism, including tariffs, import quotas, domestic subsidies and government legislation or regulation.
APPLICATION
Jaguar Land Rover
Jaguar Land Rover provides a useful real-world example of how protectionism can affect a business. JLR produces many vehicles in the UK and sells into overseas markets, including the United States. When tariffs are placed on imported vehicles, UK-made cars become more expensive to sell in that market.
A tariff can reduce price competitiveness. If JLR faces a higher import tax when selling cars into the United States, it may have to increase prices for customers, accept lower profit margins or absorb some of the extra cost. For a premium car manufacturer, some customers may still be willing to pay higher prices, but demand could still be affected if rivals produce locally and avoid the same tariff.
Protectionism can also affect cash flow and strategic planning. If tariffs suddenly increase costs, JLR may delay shipments, review pricing or reconsider its production and market-entry strategy. This shows that protectionism can create uncertainty as well as direct cost increases.
The impact is not limited to JLR. Suppliers, employees and local communities may also be affected. If exports fall, production volumes may be reduced, which could affect demand for components, factory utilisation and employment in the wider supply chain.
However, protectionism may benefit domestic producers in the protected country. A US car manufacturer producing inside the United States may gain an advantage because imported cars become more expensive. This could help protect domestic jobs and production, which is one reason governments may use tariffs.
The JLR example shows why businesses need to monitor trade policy as part of global strategy. Protectionism can influence pricing, profit margins, export decisions, production location and long-term investment. The key judgement is whether the business can adapt quickly enough to protect sales and profitability.

MINI CASE STUDY
North Coast Coffee Ltd is a premium coffee business which sells freshly roasted coffee beans through its online store and a small chain of independent cafés. The business has experienced strong sales growth due to increasing demand for high-quality speciality coffee products.
The business generates annual revenue of £250,000. Its cost of sales, including coffee beans, packaging and direct production costs, totals £100,000. North Coast Coffee Ltd also faces operating expenses of £80,000, including marketing, employee wages, rent and administration costs. In addition, the business pays £20,000 in interest and taxation each year.
The owner, Mia Thompson, is reviewing the company’s profitability because rising wage costs and increased competition in the premium coffee market have started to place pressure on operating profit margins. She is considering increasing prices slightly in order to protect profitability while still maintaining customer demand.
