Customs Union

Definition

A customs union is a type of trade agreement where member countries eliminate tariffs on trade among themselves and adopt a common external tariff on imports from non-member countries. This arrangement promotes trade between member nations while also protecting their economies from external competition by creating a unified tariff system.

Review Questions

• How does a customs union differ from a free trade area in terms of tariff policies?
  • A customs union differs from a free trade area primarily in that member countries in a customs union adopt a common external tariff for imports from non-member nations. In contrast, while free trade areas eliminate tariffs among members, each country maintains its own individual tariffs on goods from outside the area. This means that customs unions create more cohesive trade policies among members compared to free trade areas, leading to uniformity in external trade relations.
• Discuss the role of MERCOSUR as a customs union and its impact on regional trade in South America.
  • MERCOSUR, or the Southern Common Market, serves as a customs union aimed at fostering economic integration among its member countries in South America. By eliminating tariffs on intra-regional trade and establishing a common external tariff for imports from non-member countries, MERCOSUR has increased trade volume among its members. This integration has enhanced economic cooperation and competitiveness within the region but has also faced challenges related to political differences and economic disparities among members.
• Evaluate the effectiveness of customs unions in promoting economic growth among member states compared to other forms of regional integration like common markets.
  • Customs unions can effectively promote economic growth among member states by facilitating increased trade through reduced barriers and a unified tariff policy. However, they may not be as effective as common markets in achieving deeper economic integration because common markets allow for the free movement of labor and capital in addition to goods and services. While customs unions focus on tariff elimination and uniformity in external trade policies, common markets foster broader economic cooperation, potentially leading to higher growth rates due to more extensive integration. Evaluating their effectiveness requires examining specific outcomes such as GDP growth rates, employment levels, and overall economic resilience among member states.
