A decision you can investigate
- A seller inside a trading bloc gains easier access to other members. An outside seller may still face border duties.
- Integration among members can change competition faced by non-members.
Build the explanation
- A trading bloc gives members preferential access under an agreement. A free-trade area reduces internal trade barriers; a customs union 关税同盟 also has a common external tariff. The EU customs union is a named example.
- Members may gain larger markets and lower input prices, while firms face stronger competition. Non-member suppliers may lose sales if preferences favour member products; they may also sell more to a growing bloc economy.
Work through the evidence
- In a fictional bloc choice, a non-member product costs 8 before a tariff of 3: delivered price 11. A member product costs 10 without the internal tariff. A buyer switches to the member although its production cost is higher.
- The WTO provides a framework for negotiating trade agreements, monitoring implementation and resolving disputes about commitments. It does not run every member’s customs service or guarantee an instant end to trade disagreements.
What is the outsider’s tariff-inclusive price?
8 plus the tariff 3 equals 11.
Test the limits
- Preferential access can create trade by replacing costly domestic production, or divert purchases away from a lower-cost outside supplier. Evaluate the actual tariff and cost comparison.
- Official references: EU customs union and WTO monitoring, disputes. Institutional roles checked 2026-10-02; no current dispute outcome is claimed.
Which distinguishes a customs union from a free-trade area?
Internal preferences alone do not imply a shared external tariff.
Joining a bloc guarantees every member firm benefits from the additional competition.
Some firms gain markets; others can lose sales to member competitors.
Apply and explain your answer
- Why is the switch in the fictional example not proof of buying from the lowest-cost producer?
- The outside producer’s cost is 8; the tariff preference makes its delivered price exceed the member’s 10.
Which is a WTO role?
Monitoring agreements is an institutional function.
Use the terms precisely
- customs union: A bloc with reduced internal tariffs and a common external tariff.
- World Trade Organization 世界贸易组织: An institution supporting trade agreements, monitoring and dispute settlement.
Match the terms to their meanings.
