The methods and effects of protectionism including tariffs, quotas and subsidies, the role and impact of trading blocs and free-trade agreements, and how protectionism and trading blocs affect business decisions and competitiveness.

What this theme is asking

OCR wants you to explain the methods of protectionism (tariffs, quotas, subsidies), the role and impact of trading blocs and free-trade agreements, and how both affect business decisions and competitiveness. Tariff calculations and the effects of blocs are staples of Component 3.

Protectionism and its methods

The effects cut both ways. Protectionism helps domestic producers (cheaper relative to imports, protecting sales and jobs) and raises government revenue (from tariffs). But it raises prices for consumers (imports cost more, competition is reduced), can make domestic firms complacent and inefficient (shielded from competition), and risks retaliation (other countries imposing their own barriers), which can spark a trade war that harms exporters.

Tariffs in numbers

A tariff is usually a percentage added to the price of an import. A $20\%$ tariff on a $\pounds 50$ import raises its price to the consumer to $\pounds 50 \times 1.20 = \pounds 60$. This makes the import less competitive against domestic rivals, the intended effect, but also makes the good dearer for consumers and for any domestic firm that uses the import as an input.

Trading blocs and free-trade agreements

Membership of a bloc reshapes business strategy: firms gain a large home market and economies of scale but must compete with efficient rivals across the bloc and comply with shared regulations. Firms outside a bloc may face a common external tariff, which can prompt them to set up production inside the bloc to get around it.

How protectionism and blocs affect business decisions

Protectionism and bloc membership shape where firms produce (setting up inside a bloc to avoid its external tariff), how they price (passing on or absorbing tariff costs), which markets they target, and how they manage risk (diversifying to reduce exposure to one country's trade policy). A change in trade policy, a new tariff, a country leaving or joining a bloc, can force a significant strategic response.

Examples in context

Tariffs imposed in trade disputes between major economies have forced firms to reroute supply chains and raise prices. Carmakers and other manufacturers have located plants inside trading blocs to gain tariff-free access and avoid external tariffs. Changes in the UK's trading relationship with the EU prompted many firms to reassess supply chains, customs procedures and where to base operations, illustrating how trade arrangements drive business decisions.

• Cue. A tariff is a tax on imports that raises their price; a quota is a physical limit on the quantity that can be imported.

Q2. Analyse one drawback to consumers of a government imposing tariffs on imports. [6 marks]

• Cue. Tariffs raise import prices and reduce competition, so consumers pay more and have less choice, developed as a chain in context.
