Protectionism

Protectionism is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Protectionism rather than just read about it. In short: Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the producers, businesses, and workers of the import-competing sector in the country from foreign competitors and raise govern…

Key takeaways

  • Protectionism belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Protectionism to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Protectionism from memory before moving on to harder problems.

Reference excerpt

Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the producers, businesses, and workers of the import-competing sector in the country from foreign competitors and raise government revenue. Opponents argue that protectionist policies reduce trade, and adversely affect consumers in general (by raising the cost of imported goods) as well as the producers and workers in export sectors, both in the country implementing protectionist policies and in the countries against which the protections are implemented. Protectionism has been advocated mainly by parties that hold economic nationalist positions, while economically liberal political parties generally support free trade. There is a consensus among economists that protectionism has a negative effect on economic growth and economic welfare, while free trade and the reduction of trade barriers have a significantly positive effect on economic growth. Many mainstream economists, such as Douglas Irwin, have implicated protectionism as an important contributing factor in some economic crises, most notably the Great Depression. A more reserved perspective is offered by New Keynesian economist Paul Krugman, who argues that tariffs were not the main cause of the Great Depression but rather a response to it, and that protectionism is a minor source of allocative inefficiency. Although trade liberalization can sometimes result in unequally distributed losses and gains, and can, in the short run, cause economic dislocation of workers in import-competing sectors, free trade lowers the costs of goods and services for both producers and consumers.

Protectionist policies

A variety of policies have been used to achieve protectionist goals. These include:

Worked examples

Example 1 — a first encounter with Protectionism

Start with the simplest possible case. Write down what Protectionism claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Protectionism before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Protectionism ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Protectionism

In research
Protectionism appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Protectionism in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Protectionism is common in secondary-school and first-year university syllabi. It links to neighbouring topics Commercial policy, Economic ideologies, Economic nationalism, so understanding it makes those chapters shorter.
In everyday life
Look for Protectionism outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the pr…

Why does Protectionism matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Protectionism?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
