Sub-topic 5: International Trade and Capital Flows
This module delves into the fundamental concepts of international trade and capital flows, crucial for understanding global economic dynamics and their impact on financial markets. We will explore the theories behind trade, the benefits and costs, and the mechanisms of capital movement across borders.
Theories of International Trade
Understanding why countries trade is the first step. Several theories explain this phenomenon, each offering a different perspective on the drivers of trade.
Countries should specialize in producing goods/services where they have a lower opportunity cost and trade with others.
Heckscher-Ohlin Model
The Heckscher-Ohlin (H-O) model expands on comparative advantage by focusing on factor endowments. It suggests that countries export goods that make intensive use of the factors of production (like labor, capital, land) that they have in abundance and import goods that make intensive use of factors they have in scarcity.
| Theory | Primary Driver | Key Concept |
|---|---|---|
| Comparative Advantage (Ricardo) | Relative efficiency / Opportunity cost | Specialization based on lower opportunity cost |
| Heckscher-Ohlin Model | Factor endowments (labor, capital, land) | Export goods intensive in abundant factors, import goods intensive in scarce factors |
Benefits and Costs of International Trade
While trade generally leads to net benefits, it's important to acknowledge both the advantages and potential disadvantages.
The Stolper-Samuelson theorem suggests that opening to trade will raise the return to a country's relatively abundant factor and lower the return to its relatively scarce factor. This highlights how trade can redistribute income within a country.
International Capital Flows
Capital flows refer to the movement of financial assets across national borders. These flows can take various forms and have significant implications for economies.
Types of Capital Flows
Capital flows can be visualized as a network of financial connections between countries. Imagine a global financial system where money moves between different economies based on investment opportunities and risk assessments. This movement can be direct, like building a factory abroad (FDI), or indirect, like buying foreign stocks (portfolio investment). The diagram below illustrates the general concept of capital flowing from countries with surplus capital to those with deficits or higher investment potential.

Impact of Capital Flows
The impact of capital flows is multifaceted, affecting exchange rates, interest rates, domestic investment, and overall economic stability. Understanding these dynamics is crucial for policymakers and investors alike.
Foreign Direct Investment (FDI) and portfolio investment.
Trade and Capital Flows in Financial Markets
The interplay between international trade and capital flows significantly influences financial markets, affecting asset prices, currency values, and investment strategies.
The 'carry trade' is a strategy that exploits interest rate differentials between countries, often involving borrowing in a low-interest-rate currency and investing in a high-interest-rate currency. This is a direct example of how capital flows are driven by financial incentives.
