Protectionism: quotas, legislation, subsidies and the impact on business

Import quotas

An import quota is a physical limit on the quantity (or value) of a good that can be imported in a period. Because supply is restricted, the domestic price rises. Domestic producers sell more at a higher price. Unlike a tariff, the government collects no revenue unless it sells import licences; foreign exporters who hold the quota may earn higher prices (quota rents). Quotas give certainty about the maximum level of imports.

Other trade barriers

Government legislation: product standards, safety and labelling rules, health checks on food, environmental rules, local content requirements, complicated customs procedures, and rules on public procurement favouring domestic suppliers. These can be genuine protection of consumers or disguised protectionism.

Domestic subsidies: payments or tax breaks to domestic producers that lower their costs, so they can charge lower prices at home and abroad. Subsidies shift the domestic supply curve to the right, increasing domestic output and reducing imports, but cost taxpayers money and may lead to retaliation or WTO disputes.

Impact on businesses of protectionism

• Protected domestic firms gain sales, prices and profits in the short run, but may become complacent and inefficient.
• Firms using imported inputs face higher costs or shortages.
• Exporters may face retaliation and lose overseas markets.
• Foreign firms lose access; they may switch to FDI, licensing or joint ventures inside the protected market.
• Consumers pay higher prices and have less choice, which can reduce demand for other products.
• Uncertainty about future barriers makes planning and investment harder, and supply chains may be redesigned (reshoring or moving to countries with better access).

Worked example

A country sets an import quota of 30,000 cars. Before the quota, 50,000 cars were imported each year. Explain the effect on a domestic car maker.

1. Imports are cut by 20,000 cars.
2. Buyers who cannot get imported cars turn to domestic cars, so demand for the domestic maker rises.
3. With less competition, the domestic maker can also raise prices, increasing revenue and profit in the short run.

Answer: Higher sales and prices for the domestic maker, at least in the short run.

Check yourself

1. An import quota is
   • a tax on each imported unit
   • a payment to domestic producers
   • a physical limit on the quantity of a good that can be imported
   • a ban on all exports
   Show answer

   a physical limit on the quantity of a good that can be imported. Quotas restrict quantity; tariffs tax price.

2. Before a quota, 120,000 tonnes of rice were imported. The quota is set at 75,000 tonnes. By what percentage are imports cut?
   Show answer

   37.5 %. 45,000 / 120,000 x 100 = 37.5%.

3. A government pays domestic farmers a subsidy of $15 per tonne on 2.4 million tonnes. What is the cost to the government, in $ million?
   Show answer

   36 $ million. 15 x 2.4 million = $36 million.

4. Which statement about quotas compared with tariffs is correct?
   • A quota always raises more revenue than a tariff
   • A quota raises no government revenue unless import licences are sold
   • A quota lowers the domestic price
   • A quota increases the quantity imported
   Show answer

   A quota raises no government revenue unless import licences are sold. Quotas restrict quantity rather than taxing it.

5. Explain how government legislation can act as a trade barrier.
   Show answer

   Strict product standards, safety or labelling rules and complicated customs checks raise the cost for foreign firms of meeting the rules, so fewer imports enter the market.. Regulations raise the cost of entry for foreign producers.

6. Explain how a domestic subsidy can make imports less competitive.
   Show answer

   The subsidy lowers domestic producers' costs, so they can cut their prices, making imported goods relatively more expensive and reducing demand for them.. Subsidies give domestic firms a cost advantage.

7. Why might long-term protection be bad for a protected domestic industry?
   • It always reduces the industry's profits immediately
   • It increases imports
   • It lowers the prices the industry can charge
   • Less competition reduces the incentive to cut costs and innovate
   Show answer

   Less competition reduces the incentive to cut costs and innovate. Without competitive pressure, firms may become inefficient.
