Theories of Economic Development

Why are some countries rich while others are poor? How can sustained economic development be achieved? These questions are central to the political economy of development, and very different answers to them have been given over the past seventy years.

Modernization Theory

Dominated in the 1950s–1960s:

Key idea: Development is a universal process of transition from a traditional society to a modern one. All countries go through the same stages.

Rostow's Stages:

Traditional society
Preconditions for take-off
Take-off
The drive to maturity
The age of mass consumption

Political consequences: Developing countries need to copy the path of developed ones: industrialization, urbanization, Western institutions and values.

Criticism:

Ignores colonial heritage
Western-centrism—one path for all
Underestimation of international structural constraints

Dependency Theory (dependencia)

A Latin American response to modernization:

Key idea: Underdevelopment is not lagging behind, but the result of being embedded in the world system under subordinate conditions. Development of the center and underdevelopment of the periphery are two sides of the same process.

Mechanisms of dependency:

Unequal exchange—raw materials depreciate, manufactured goods appreciate
Leakage of surplus value to the metropolis
Comprador elites dependent on external connections
Technological dependence

Prescriptions: Import substitution, regional integration, breaking dependence relationships, socialist transformation.

Criticism:

East Asian success refutes the thesis that development through integration is impossible
Internal factors are underestimated
Import substitution did not work

Neoliberal Consensus

Dominated since the 1980s:

Key idea: The market is the best mechanism for allocating resources. State intervention distorts incentives. Developing countries need "correct" policies.

Washington Consensus:

Fiscal discipline
Reduction of subsidies
Tax reform
Liberalization of interest rates
Competitive exchange rate
Trade liberalization
Attraction of foreign direct investment
Privatization
Deregulation
Protection of property rights

Results: Ambiguous. "Lost decade" in Latin America. Asian crisis. Rising inequality. But some countries stabilized.

Institutional Turn

Since the 1990s—a focus on institutions:

"Institutions matter." Douglass North: Formal and informal rules of the game determine incentives and outcomes.

Key institutions for development:

Protection of property rights
Rule of law
Contract law
Limiting corruption
Efficient bureaucracy

Acemoglu and Robinson: inclusive vs. extractive institutions.

Inclusive: Broad access to opportunities, limitation of elites—lead to prosperity.

Criticism: Institutions are not an exogenous factor. Where do good institutions come from? How to create them?

Developmental State

An alternative view based on the East Asian experience:

Key idea: An active, competent state directs development. Industrial policy, investment coordination, creation of comparative advantages.

Examples:

Japan (MITI)
South Korea (chaebols + state)
Taiwan
Singapore
China

Conditions for success:

Competent, meritocratic bureaucracy
Autonomy from capture by interests
Embedded autonomy—connection to business without capture
Business discipline—aid in exchange for results

Criticism: Not easily reproducible. Conditions are unique. Corruption and failures in other contexts.

Contemporary Approaches

Today—eclecticism and pragmatism:

"Growth diagnostics" (Hausmann, Rodrik): No universal prescriptions. Diagnosis of specific development barriers in a particular country is needed.

Randomized experiments (Banerjee, Duflo): What works must be tested experimentally. Micro-interventions with measurable impact.

Complexity and economic sophistication: Development is the accumulation of "capabilities." Diversity and complexity of exports predict growth.

Green development: The climate crisis demands a new path. Low-carbon development is both a challenge and an opportunity.
