WTO Principles and International Trade Theories Explained

WTO Agreements and Core Functions

The WTO agreements cover goods, services, and intellectual property. They manage these areas under the principles of liberalization—with permitted exceptions—to achieve lower customs tariffs and to keep services markets open.

Key WTO Responsibilities

• Handling Trade Disputes: The WTO’s procedure for resolving trade quarrels under the Dispute Settlement Understanding is vital for enforcing rules and ensuring smooth trade flows.
• Monitoring and Support: Monitoring national trade policies while providing technical assistance and training for developing countries.
• Institutional Cooperation: Collaborating with international institutions such as the IMF and the World Bank.

International Trade Theories

Absolute Advantage (Adam Smith)

Two countries can benefit from trade if they specialize in the goods they produce more efficiently than their rivals and trade with each other.

Comparative Advantage (David Ricardo)

If a country specializes in the production of goods and services in which it is relatively efficient compared to its competitors, it will be better off. Specialization promotes efficiency, making trade a positive-sum game where all parties benefit, even if one has an absolute advantage. Note: Differences in labour productivity are the only determinants of comparative advantage in this model.

Factor Endowment (Heckscher-Ohlin)

Comparative advantage arises from the different relative factor endowments of countries (capital, land, labor). Countries will have a comparative advantage in industries that utilize the natural advantages or endowments of that country.

Protectionism: Objectives and Instruments

The objective of protectionism is to shield domestic production and increase import prices.

Instruments of Protection

• Tariffs: Taxes on imported goods designed to protect domestic industry. An external tariff increases the price of foreign products, making it more difficult to compete with domestic alternatives.
• Import Quotas: A limitation on the quantity of foreign products allowed to be imported, regardless of price. These limit supply and increase domestic prices, acting as an obstacle when international prices decrease.
• Non-Tariff Barriers (NTB): Administrative regulations used to discriminate against foreign products in favor of domestic ones. Examples include complex customs processes, strict quality and health regulations, or other administrative measures that act as obstacles to international commerce.
