IB Economics - Preferential Trade Agreements and Trading Blocs

This study note for IB economics covers Preferential Trade Agreements and Trading Blocs

1. Introduction to Preferential Trade Agreements

Preferential trade agreements (PTAs) are treaties between two or more countries that provide certain trade benefits, such as reduced tariffs or other forms of trade concessions. These agreements aim to foster closer economic ties by providing easier access to each other's markets.

Key Points:

• Purpose: To promote trade between member countries by offering benefits not extended to non-members.
• Forms: PTAs can be bilateral, involving two countries, or multilateral, involving more than two countries.
• Benefits: Include reduced tariffs, quotas, and other trade barriers for member countries.

2. Bilateral vs. Multilateral Trade Agreements

Bilateral Trade Agreements:

• Involve two countries.
• Aim to increase trade and economic cooperation between the two nations.
• Examples:
  • US-Mexico-Canada Agreement (USMCA): Replaced NAFTA and aims to increase trade between the US, Mexico, and Canada.
  • Australia-China Free Trade Agreement (ChAFTA): Reduces tariffs on Australian exports to China and vice versa.

Multilateral Trade Agreements:

• Involve multiple countries, often under the framework of international organizations like the World Trade Organization (WTO).
• Aim for broader trade liberalization and often involve complex negotiations.
• Example:
  • WTO Agreements: Include over 160 member countries and cover various aspects of global trade, aiming to reduce trade barriers worldwide.

Distinctions:

• Bilateral agreements are simpler and quicker to negotiate but cover less market scope.
• Multilateral agreements are more comprehensive and reduce global trade barriers but require complex and lengthy negotiations.

3. Preferential Access in Trade Agreements

• Definition: Preferential trade agreements allow member countries to enjoy benefits like lower tariffs or better market access that are not available to non-members.
• Mechanisms:
  • Tariff reductions or eliminations: Lowering or removing duties on imports from member countries.
  • Non-tariff barriers reduction: Easing regulations, quotas, or customs procedures to facilitate smoother trade flows.

Example:

• European Union (EU) Single Market: Provides member states with tariff-free access to goods and services, promoting high levels of trade integration.

4. Types of Trading Blocs

Trading blocs are groups of countries that join together to enhance trade among themselves, often by reducing or eliminating trade barriers.

Types of Trading Blocs:

1. Free Trade Area (FTA):
   • Definition: Member countries remove tariffs and quotas between themselves but maintain independent trade policies with non-members.
   • Example: North American Free Trade Agreement (NAFTA) before it was replaced by USMCA.
2. Customs Union:
   • Definition: Similar to an FTA, but member countries adopt a common external tariff on imports from non-member countries.
   • Example: Southern African Customs Union (SACU), which includes South Africa, Namibia, Lesotho, Botswana, and Eswatini.
3. Common Market:
   • Definition: Extends beyond a customs union by allowing free movement of goods, services, capital, and labor among member countries.
   • Example: The European Economic Area (EEA) allows countries like Norway and Iceland access to the EU single market.

Distinctions:

• FTAs focus solely on reducing internal trade barriers, while customs unions unify external trade policies.
• Common markets not only harmonize trade policies but also integrate labor and capital markets.

5. Economic Integration and Competition

• Impact on Competition: Economic integration within a trading bloc increases competition among producers as they gain access to a larger market without internal barriers.
• Advantages:
  • Promotes efficiency and innovation.
  • Reduces prices for consumers due to increased competition.
  • Encourages businesses to scale up, benefiting from economies of scale.

Example:

• EU Single Market: Drives competition across member states, compelling firms to improve efficiency and innovation.

6. Trade Creation and Trade Diversion (HL ONLY)

Trade Creation:

• Occurs when a trading bloc enables more efficient producers within member states to replace less efficient domestic producers.
• Example: The establishment of the EU led to increased trade among member states due to reduced tariffs, benefiting efficient producers.

Trade Diversion:

• Occurs when trade is shifted from a more efficient non-member producer to a less efficient member producer due to preferential treatment within the bloc.
• Example: After joining the EU, some countries may import from less efficient EU member countries instead of more efficient non-member countries because of common external tariffs.

7. Economic Integration and Economies of Scale (HL ONLY)

• Definition: Economies of scale refer to the cost advantages that enterprises obtain due to scale of operation, with cost per unit of output generally decreasing with increasing scale.
• Integration Benefits:
  • Access to larger markets allows firms to expand production.
  • Spreading fixed costs over more units, reducing average costs.
  • Enhanced ability to invest in R&D and improve product quality.

Example:

• Airbus in the EU: Leverages the integrated EU market to achieve economies of scale in aircraft production.

Glossary of Key Terms

• Bilateral Agreement: A trade agreement between two countries.
• Common Market: A type of trading bloc with free movement of goods, services, capital, and labor among member countries.
• Customs Union: A trading bloc where member countries adopt a common external tariff.
• Economies of Scale: Cost advantages that enterprises obtain due to scale of operation.
• Free Trade Area (FTA): A group of countries that have removed tariffs and quotas between themselves but maintain independent trade policies with non-members.
• Multilateral Agreement: A trade agreement involving more than two countries, often under a broader framework like the WTO.
• Preferential Trade Agreement (PTA): An agreement that gives preferential access to certain products from certain countries by reducing or eliminating tariffs or other trade barriers.
• Trade Creation: When trade increases within a trading bloc due to reduced tariffs, leading to more efficient production.
• Trade Diversion: When trade is redirected from a more efficient non-member producer to a less efficient member producer due to preferential treatment within the bloc.
• Trading Bloc: A group of countries that have joined together to enhance trade between themselves.
