Customs Unions

Definition

A customs union is a type of trade agreement where participating countries eliminate tariffs and other trade barriers on goods traded among themselves, while maintaining a common external tariff on goods imported from non-member countries. This allows for the free movement of goods within the union while providing collective bargaining power in international trade negotiations.

2. The common external tariff applied by customs union members acts as a barrier to trade with non-member countries, potentially leading to trade diversion.
3. Customs unions can generate economies of scale, increase competition, and allow for more efficient allocation of resources within the union.
4. The European Union (EU) is an example of a successful customs union, with member states forming a single market with free movement of goods, services, capital, and labor.

Review Questions

• Explain how a customs union differs from a free trade area in terms of trade policy.
  • The key difference between a customs union and a free trade area is the treatment of trade with non-member countries. In a customs union, members maintain a common external tariff on imports from non-member countries, while in a free trade area, each member country sets its own tariffs on imports. This means that in a customs union, there is a unified trade policy towards the rest of the world, while in a free trade area, each member country has its own independent trade policy.
• Analyze the potential economic benefits and drawbacks of a customs union for its member countries.
  • Potential benefits of a customs union include increased trade and economic integration among members, economies of scale, and more efficient allocation of resources. However, customs unions can also lead to trade diversion, where members start trading more with each other and less with non-member countries, potentially reducing overall global welfare. Additionally, the coordination required to align trade policies, regulations, and administrative procedures can be challenging and time-consuming for member countries.
• Evaluate the role of customs unions in the context of how governments enact trade policy globally, regionally, and nationally.
  • Customs unions are an important tool in how governments enact trade policy at the regional level. They allow countries to integrate their economies and increase their collective bargaining power in international trade negotiations. At the global level, customs unions can be seen as an intermediate step towards more comprehensive trade liberalization, as they remove barriers to trade among members while maintaining a common external tariff. Nationally, the formation of a customs union requires significant coordination and compromise among member countries, as they must align their trade policies and regulations. This highlights the complex interplay between national, regional, and global trade policy decisions.
