Why Countries Trade
Explore the fundamental reasons that drive international trade and economic exchange.
Specialization
Resource Differences
Efficiency Gains
Countries engage in international trade for several key reasons: differences in resource endowments, technology, climate, and consumer preferences. Trade allows countries to specialize in producing what they do best and import what others produce more efficiently.

Patterns of World Trade
Analyze global trade flows and understand which countries trade what with whom.
Key Trade Patterns:
• Most trade occurs between developed countries
• Intra-industry trade is increasingly important
• Regional trade blocs shape trade flows
• Services trade is growing rapidly
Trade Composition Trends:
• Manufacturing goods dominate global trade
• Primary commodities still important for developing countries
• Digital services creating new trade opportunities
• Global value chains fragment production

Gains from Trade
Understand how international trade creates value and benefits all participating countries.
Types of Gains from Trade:
• Static gains: Better resource allocation at a point in time
• Dynamic gains: Long-term benefits from competition and innovation
• Consumer gains: More variety and lower prices
• Producer gains: Access to larger markets
Potential Trade Costs:
• Adjustment costs for displaced workers and industries
• Increased income inequality in some cases
• Reduced policy autonomy
• Environmental concerns from increased transport
