Protectionism

Protectionism refers to government measures that restrict imports or favor domestic producers over foreign competitors. The most common tools are tariffs (taxes on imports), quotas (quantitative limits), subsidies to local industries, non-tariff barriers such as licensing requirements or technical standards, and currency interventions. Governments typically justify these measures on grounds of protecting nascent industries ("infant industry" argument associated with Friedrich List and Alexander Hamilton), safeguarding employment, ensuring national security in strategic sectors, or correcting unfair foreign practices like dumping.

Protectionism stands in contrast to free trade, the doctrine articulated by Adam Smith and David Ricardo, who argued that comparative advantage produces mutual gains from open exchange. After the destructive trade wars of the 1930s — exemplified by the U.S. Smoot-Hawley Tariff Act of 1930, which raised duties on thousands of imports and triggered retaliation — postwar planners built a rules-based system through the General Agreement on Tariffs and Trade (GATT) in 1947, succeeded by the World Trade Organization (WTO) in 1995. These regimes commit members to most-favored-nation treatment and progressive tariff reduction, while allowing limited safeguards.

Despite decades of liberalization, protectionism never disappeared. It persists in agricultural subsidies (the EU's Common Agricultural Policy, U.S. farm bills), anti-dumping duties, "Buy National" procurement rules, and export controls. Since the mid-2010s, observers have noted a resurgence sometimes labeled "neo-protectionism" or "geoeconomics," driven by concerns over supply-chain resilience, China's industrial policy, and climate-linked measures such as the EU's Carbon Border Adjustment Mechanism.

Economists generally find that broad protectionist measures raise consumer prices, invite retaliation, and reduce aggregate welfare, though targeted use may be defensible for genuine security or development objectives. The political appeal remains strong because costs are diffuse while benefits to protected sectors are concentrated and visible — a dynamic Mancur Olson described in The Logic of Collective Action (1965).
