Rich Countries Create Poor Countries

The Dependency Theory

Definition: What is Dependency Theory?

Dependency theory argues that the global economy is structured into two groups: core and periphery countries. Core countries are industrialized and wealthy, while periphery countries specialize in exporting raw materials. Developed by Andre Gunder Frank, the theory holds that underdevelopment is not a stage of progress but a condition produced by integration into the global economic system.

Core Claim

The central claim of dependency theory is that economic relationships between richer and poorer countries are structurally unequal. Richer countries control higher-value activities such as manufacturing and technology, while poorer countries are largely confined to lower-value activities such as raw material extraction. As a result, growth in rich countries occurs alongside—and is partly supported by—the limited development of poorer countries.

To understand this, it is necessary to examine how the system operates.

Mechanism: How the System Operates

1. Poorer countries specialize in extracting and exporting raw materials.
2. Richer countries specialize in higher-value activities such as manufacturing, technology, and design.
3. These activities generate higher and more stable returns.
4. Over time, this leads to greater accumulation of income and capital in richer countries.
5. This imbalance limits the ability of poorer countries to industrialize and move into higher-value sectors.

To understand why this imbalance persists, it is necessary to examine the underlying economic forces.

Evidence: Unequal Trade Dynamics

According to Hans Singer and Raúl Prebisch, the terms of trade tend to move against commodity exporters over time.

Income Elasticity of Demand

• Demand for manufactured goods rises faster than demand for commodities as incomes increase
• Supports stronger long-run growth in industrial sectors
• Example: higher incomes increase spending on electronics more than basic food

Productivity Asymmetry

• Manufacturing retains productivity gains as profit (due to differentiation)
• Commodity sectors pass gains into lower prices (due to competition)
• Example: branded cars vs. undifferentiated copper

Market Structure

• Manufacturing: few firms, pricing power, branding, intellectual property
• Commodities: many producers, homogeneous goods, price takers

Value Chain Position

• High-value stages: design, branding, technology
• Low-value stage: raw material extraction
• Result: core countries capture a larger share of total value

This raises a key question: if these patterns are disadvantageous, why do poorer countries not simply industrialize?

5. Constraints: Why Industrialization is Difficult

Structural Constraints

• Path dependence Existing specialization shapes infrastructure, skills, and institutions
• High entry barriers Industrialization requires capital, skilled labor, and infrastructure
• Coordination failure Multiple industries and systems must develop simultaneously
• Incentive structure Commodity exports offer immediate returns; industry involves risk and delay

Reinforcing Factors

Financial dependence

• Reliance on external borrowing and investment
• Limits policy autonomy and diverts resources to debt servicing

Multinational corporations

• Control over technology, supply chains, and high-value activities
• Profits often repatriated

Domestic political economy

• Elites benefit from commodity exports and short-term stability
• Weak state capacity limits industrial policy

Historical legacy

• Colonial systems designed for extraction, not industrial development

Global power asymmetry

• Core countries influence trade rules and global institutions

These constraints and reinforcing forces make structural transformation difficult, allowing dependence to persist over time.

Observable Outcomes

• Limited industrial diversification
• Dependence on a narrow range of primary exports
• Volatile and constrained economic growth
• Persistent or widening income gaps
• Trade imbalances
• High vulnerability to external shocks

These outcomes describe the typical pattern predicted by dependency theory in many resource-dependent economies.

Limitation and Next Framework

However, this pattern is not universal. The experience of countries such as China, South Korea, and Singapore shows that some economies have successfully moved from low-value specialization to industrialized, high-value production.

This suggests that external constraints do not fully determine development outcomes. In response to this limitation, an alternative framework—the developmental state perspective—focuses on how coordinated industrial policy and state-led strategy can enable structural transformation.

This will be the focus of a separate essay.
