International Trade

International trade refers to the exchange of goods and services between two or more countries. Unlike internal trade (trade within a country), international trade involves different currencies, legal systems, and cultural barriers.

1. Basis for International Trade

The fundamental reason countries trade is the unequal distribution of resources and differences in production efficiency. Key theories include:

• Absolute Advantage (Adam Smith): A country has an absolute advantage if it can produce more of a commodity using the same amount of resources as another country.
• Comparative Advantage (David Ricardo): This theory suggests that trade is beneficial even if one country is more efficient in producing all goods. A country should specialize in producing the good for which it has the lowest opportunity cost.

2. Balance of Trade and Balance of Payments

Balance of Trade (BOT): This is the difference between the value of a country's visible exports (tangible goods like oil, cocoa) and visible imports.

Balance of Payments (BOP): This is a comprehensive record of all economic transactions between residents of a country and the rest of the world over a period (usually a year). It includes:

• Current Account: Records trade in goods (visible) and services (invisible), and net income/transfers.
• Capital Account: Records investment flows (FDI, loans, portfolio investments).

BOP Disequilibrium: This occurs when total receipts do not equal total payments. A deficit occurs when payments exceed receipts.

Corrective Measures for BOP Deficit:

• Devaluation: Deliberate reduction in the value of the local currency.
• Tariffs and Quotas: Taxes on imports or physical limits on quantities.
• Export Promotion: Giving incentives to local producers to export more.
• Exchange Control: Government restriction on the amount of foreign currency available to importers.

3. Nigeria's Foreign Trade

• Composition: Nigeria's exports are heavily dominated by Crude Oil (over 90%), followed by agricultural products like cocoa and sesame seeds. Imports consist mainly of machinery, refined petroleum, and food items.
• Direction: Nigeria trades significantly with the European Union, India, China, and the United States.

4. Exchange Rates

An exchange rate is the price of one currency in terms of another.

• Fixed Exchange Rate: The rate is set and maintained by the government or central bank.
• Flexible/Floating Exchange Rate: The rate is determined by the market forces of demand and supply.
• Managed Float: A hybrid system where the rate floats but the central bank intervenes to prevent extreme fluctuations.
