Protecting Local Industries: Trade Barriers

Students will discuss why some people want to protect local businesses from foreign competition using tools like taxes on imports (tariffs) and limits on foreign goods (quotas).

• MOE Syllabus Outcomes
• MOE: International Trade - Middle School

About This Topic

The Balance of Payments (BOP) and exchange rates are the financial links that connect a nation to the rest of the world. Students learn to analyze the components of the BOP, including the current and capital/financial accounts, and understand how they must balance. In Singapore, our persistent current account surplus and our unique exchange rate management system are central to our macroeconomic stability.

The MOE syllabus focuses on the factors that determine exchange rates in a free-floating system and the different types of exchange rate regimes. Students must evaluate the impact of a fluctuating currency on a nation's trade balance and overall economic performance. This topic comes alive when students can use real-time currency data and BOP statements to analyze a country's external position.

Key Questions

1. Why might a country want to limit goods coming from other countries?
2. What are tariffs and quotas, and how do they affect prices?
3. What are the good and bad things about protecting local industries?

Learning Objectives

• Explain the economic rationale behind using trade barriers to protect domestic industries.
• Analyze the impact of tariffs and quotas on the prices of imported goods and domestic substitutes.
• Evaluate the advantages and disadvantages of protectionist policies for consumers, producers, and the national economy.
• Compare and contrast the effects of tariffs and quotas on market outcomes.
• Critique arguments for and against protecting specific local industries from international competition.

Before You Start

Supply and Demand

Why: Students need to understand how prices and quantities are determined in a market to analyze the effects of trade barriers.

Market Equilibrium

Why: Understanding equilibrium helps students visualize how shifts in supply or demand, caused by trade barriers, alter market outcomes.

Forms of Market Competition

Why: Knowledge of perfect competition, monopoly, and oligopoly provides context for discussing how foreign competition affects domestic firms.

Key Vocabulary

Tariff	A tax imposed on imported goods or services. Tariffs increase the price of foreign goods, making domestic products more competitive.
Quota	A government-imposed limit on the quantity of a specific good that can be imported into a country during a certain period. Quotas restrict the supply of foreign goods.
Protectionism	An economic policy of restraining trade between countries through methods such as tariffs on imported goods, restrictive quotas, and a variety of other government regulations.
Infant Industry Argument	The argument that new domestic industries need temporary protection from international competition until they are mature enough to compete.
Dumping	The practice of exporting goods at a price lower than their normal value, often below the cost of production, which can harm domestic industries.

Watch Out for These Misconceptions

Common Misconception

A current account deficit is always a sign of economic weakness.

What to Teach Instead

A deficit can be a sign of a healthy, growing economy that is attracting foreign investment to fund productive projects. Peer-led analysis of different countries' BOP positions helps students see the context-dependent nature of these indicators.

Common Misconception

The government can set any exchange rate it wants without consequences.

What to Teach Instead

In a globalized world, a government's ability to control its exchange rate is limited by its foreign reserves and the 'impossible trinity' of economic policy. Role-playing as central bankers helps students understand these fundamental constraints.

Active Learning Ideas

Data Investigation: The BOP Detective

Groups are given the BOP statements of two very different countries (e.g., Singapore and the USA). They must identify the key trends in the current and financial accounts and explain what this tells us about each country's economic health.

Simulation Game: The Forex Market

Students act as currency traders, responding to 'news flashes' about interest rate changes, trade deals, and political events. They must decide whether to buy or sell a currency, observing how these actions cause the exchange rate to fluctuate.

40 min·Small Groups

Think-Pair-Share: How does a weak currency affect you?

Students discuss how a sudden depreciation of the Singapore dollar would affect their daily lives (e.g., the cost of overseas holidays, imported food, and their parents' jobs). They share their findings with the class.

Real-World Connections

• Singapore's government has historically supported local companies in sectors like manufacturing and aerospace through various initiatives, sometimes involving considerations of international competition.
• The United States has recently imposed tariffs on steel and aluminum imports from various countries, impacting global supply chains and domestic manufacturing costs.
• The European Union uses quotas on certain agricultural products, such as beef and poultry, to manage supply and support its own farmers.

Assessment Ideas

Discussion Prompt

Pose the question: 'Imagine Singapore decides to place a quota on imported rice to support local rice farmers. What are two potential positive outcomes for Singaporean farmers and two potential negative outcomes for Singaporean consumers?' Facilitate a class discussion where students present their points.

Quick Check

Provide students with a short case study about a hypothetical country considering imposing a tariff on imported electronics. Ask them to write down: 1. The primary reason the country might impose this tariff. 2. One likely effect on the price of electronics for consumers. 3. One likely effect on domestic electronics manufacturers.

Exit Ticket

On a slip of paper, have students define either 'tariff' or 'quota' in their own words and then list one specific industry in Singapore that might benefit from protection and why.

Frequently Asked Questions

What is the 'current account' in the BOP?

The current account records the trade in goods and services, as well as primary and secondary income flows. It is a key indicator of whether a nation is a net lender or borrower to the rest of the world. Students can practice categorizing different transactions into the correct BOP account.

How does an increase in interest rates affect the exchange rate?

Higher interest rates attract foreign capital (hot money) as investors seek higher returns. This increases the demand for the domestic currency, causing it to appreciate. Students can model this using a supply and demand diagram for the currency market.

What is the difference between a fixed and a floating exchange rate?

A fixed exchange rate is pegged to another currency or a basket of currencies by the central bank. A floating exchange rate is determined solely by market forces. Students can evaluate the pros and cons of each system for a country like Singapore.

How can active learning help students understand international finance?

International finance can be abstract and complex. By participating in a forex simulation or a BOP data investigation, students see how individual financial decisions aggregate into national-level trends. This hands-on approach makes the technical details of the BOP and exchange rates much more intuitive and easier to apply to real-world economic analysis.
