Trade and the
World Economy
Explore how global trade networks, comparative advantage, and economic structures shape spatial patterns of development and interdependence.
What Is International Trade?
International trade is the exchange of goods, services, and capital across national borders. It connects economies into a global system where countries specialize in producing what they make most efficiently, then trade for everything else.
Why Trade Matters Spatially
Trade shapes the economic landscape of the world. It determines which regions develop industry, which remain dependent on resource extraction, and how wealth is distributed across space.
Comparative Advantage: The Engine of Trade
A country has a comparative advantage when it can produce a good at a lower opportunity cost than another country. This is the foundational principle explaining why countries trade.
The Core-Periphery Model
Wallerstein's World Systems Theory divides the global economy into three tiers based on economic power and the types of goods countries produce and trade.
Free Trade vs. Protectionism
Governments must decide how open their borders are to trade. This key distinction shapes a country's economic geography.
Trade Organizations and Agreements
International institutions regulate and facilitate global trade. Their rules shape who benefits from economic exchange.
How Trade Shapes Development
Neoliberalism vs. Structuralism
Two competing perspectives explain how trade affects development differently. The AP exam expects you to contrast these views.
| Neoliberalism | Structuralism | |
|---|---|---|
| Core belief | Free markets drive growth | Global system is inherently unequal |
| Trade policy | Remove barriers, privatize | Protect infant industries |
| View of periphery | Will develop through integration | Trapped in dependency |
| Key thinker | Adam Smith, IMF/World Bank | Wallerstein, Prebisch |
| Criticism | Ignores power imbalances | Can justify inefficiency |
How to Analyze Trade on the AP Exam
Example: Nigeria's Oil Exports
Example: South Korea's Transformation
Example: The Commodity Trap
Many peripheral nations depend on exporting a single commodity. When global prices drop, their economies collapse: a phenomenon called the commodity trap.
Understanding Terms of Trade
Terms of trade measure the ratio of export prices to import prices. When this ratio declines, a country must export more to afford the same amount of imports.
Common Mistakes on the Exam
Trade Strategies Compared
| Export-Oriented (EOI) | Import Substitution (ISI) | |
|---|---|---|
| Goal | Grow by selling to world markets | Grow by replacing imports with domestic goods |
| Trade policy | Open markets, attract FDI | Tariffs, quotas to protect industry |
| Examples | South Korea, Taiwan, Singapore | Brazil (1960s), India (pre-1991) |
| Strengths | Technology transfer, efficiency | Reduces dependency, builds industry |
| Weaknesses | Vulnerability to global shocks | Inefficiency, limited markets |
