The 4 Advantages to Trade Barriers (And 3 Disadvantages) | Think Econ

Main ideas / concepts covered

• The video explains the pros and cons of international trade barriers, specifically tariffs and quotas.
• It addresses the macroeconomics question: why governments impose trade barriers if trade is generally beneficial.
• It argues that trade barriers have four main advantages and three main disadvantages, with economic reasoning for each.

Key definitions (refresher)

• Tariff: a tax imposed by a government on imports.
• Quota: a numerical limit imposed by a government on the quantity of a good that can be imported.

Advantages of trade barriers (4)

1. Increase government revenue

   • Tariffs generate tax income for the importing government, similar to other forms of taxation.

2. Promote fairer competition

   • Tariffs can reduce unfair competition in international trade.
   • They may also address price-setting inefficiencies that can arise in global markets.

3. Create leverage / a starting point for negotiations

   • Governments may use tariffs as a “last option”, but also as pressure to push trading partners toward agreements.
   • The idea is that negative effects on exporters make negotiations more urgent.
   • Example given:
     • The United States aluminum tariffs on Canada (2019) were described as a way to speed up trade agreement progress related to what became the USMCA (then NAFTA), i.e., the United States–Mexico–Canada Agreement.

4. Stimulate domestic production growth (and support jobs)

   • Tariffs raise the price of imported goods.
   • By the law of demand, higher prices reduce demand for imports.
   • Consumers shift demand toward domestically produced goods.
   • Increased demand encourages domestic producers to increase output, leading to more income and jobs.
   • The video emphasizes this is especially important for strategic and emerging industries/markets.

Disadvantages of trade barriers (3)

1. Higher prices for domestic consumers

   • Tariffs raise the selling price of imported goods in the domestic market.
   • The burden of the tax largely falls on the consumer, not the exporter.

2. Increased inefficiencies in the economy

   • Consumption inefficiency: consumers lose access to lower-priced imports.
   • Production inefficiency: inefficient domestic firms may continue operating even when their costs are higher than imported alternatives.

3. Retaliation from trade partners (risk of trade war)

   • Partner countries have incentives to protect industries that provide employment/income.
   • If tariffs suppress their industries, partners may respond with retaliatory tariffs.
   • This can escalate into a trade war, harming one or both economies.
