Protectionism

What Is Protectionism?

Protectionism is the use of government policy to shield domestic industries from foreign competition. Its main tools are tariffs, which tax imports; import quotas, which cap their quantity; export subsidies, which favor home producers; and non-tariff barriers such as restrictive standards and licensing rules. Supporters advance several arguments for protection, including safeguarding jobs, national security, and the infant-industry case that a young domestic industry may need temporary shelter until it can compete internationally. Protectionism stands in contrast to free trade, which favors removing such barriers. History offers cautionary examples: the Smoot-Hawley Tariff Act, signed by President Herbert Hoover in June 1930, sharply raised U.S. tariffs during the onset of the Great Depression.

Why It Matters

Protectionism is one of the longest-running debates in economics. Economists generally warn that broad protection reduces overall efficiency: tariffs and quotas raise prices for domestic consumers, create deadweight loss, and can invite retaliation that shrinks export markets. The Smoot-Hawley tariffs of 1930 are often cited as a case where protection backfired, contributing to a collapse in world trade as other nations retaliated. Yet protectionist arguments retain political force because the benefits, protected jobs and industries, are concentrated and visible, while the costs are spread thinly across many consumers. The infant-industry argument, national-security concerns, and worries about dumping keep protection on the policy agenda, making the tension between open trade and domestic protection a permanent feature of economic politics.
