The Two-Gap Model is a proposition in economics which suggests that the development of less developed countries (LDCs) is constrained by two primary gaps: the gap between domestic savings and the required investment for economic take-off, and the gap between export revenues and the imports needed for development. This model indicates that these gaps are not independent and are deeply intertwined.
Historical Context
The Two-Gap Model was introduced in the 1960s as economists sought to understand and address the challenges faced by LDCs in achieving sustainable economic growth. Key contributors to this model include economists such as Hollis B. Chenery and Alan M. Strout, whose work highlighted the structural issues inhibiting development.
Types/Categories of Gaps
-
Savings-Investment Gap:
- Domestic Savings: Refers to the total savings generated within a country.
- Required Investment: The investment needed to stimulate economic growth and development.
-
Foreign Exchange Gap (Trade Gap):
- Export Revenues: Income generated from goods and services sold abroad.
- Required Imports: Necessary goods and services needed for development but produced externally.
Key Events in the Development of the Two-Gap Model
- 1961: Introduction of the Two-Gap Model by Hollis B. Chenery and Alan M. Strout in their seminal paper.
- 1970s-1980s: Widespread application and testing of the model in various LDCs to formulate development strategies.
Detailed Explanations
Savings-Investment Gap
The Savings-Investment Gap refers to the shortfall between what a country can save domestically and the amount of investment required to spur growth. LDCs typically experience low savings rates due to limited income, necessitating external financial assistance.

Foreign Exchange Gap
The Foreign Exchange Gap arises when the revenue from exports is insufficient to cover the cost of necessary imports. This gap can hinder the acquisition of vital technology, machinery, and other inputs crucial for development.

Importance and Applicability
The Two-Gap Model is critical in understanding the financing needs of LDCs. It highlights:
- Need for Foreign Aid: To bridge the savings gap through grants, loans, and investments.
- Export Promotion and Import Substitution: Strategies to balance the trade gap.
- Integrated Development Policies: Policies considering both gaps to achieve sustained economic growth.
Examples
- Country A: Struggles with low savings rates and requires international loans to finance its infrastructure projects.
- Country B: Faces a significant trade deficit, needing to increase its export capacity and reduce dependency on imports.
Considerations
- External Debt Sustainability: Reliance on foreign loans can lead to debt crises.
- Effective Utilization of Aid: Ensuring aid is used productively to close gaps and promote development.
Related Terms with Definitions
- Harrod-Domar Model: Suggests economic growth depends on the level of savings and productivity of investment.
- Dependency Theory: Argues that underdevelopment in LDCs is a result of their dependence on developed countries.
Comparisons
- Two-Gap Model vs. Harrod-Domar Model: While the Harrod-Domar Model focuses solely on the savings-investment relationship, the Two-Gap Model includes the trade aspect.
Interesting Facts
- The Two-Gap Model has influenced international development policies and strategies, shaping how organizations like the World Bank and IMF approach aid distribution.

- South Korea: Initially an LDC, South Korea successfully addressed both gaps through strategic policies, transforming into a developed economy.

Summary
The Two-Gap Model provides a framework to understand the dual financial constraints faced by less developed countries. By identifying the savings-investment gap and the foreign exchange gap, it offers a blueprint for policymakers to devise strategies to promote sustainable development. The model’s impact is evident in international development strategies, making it a cornerstone of economic development theory.
