Underdevelopment stagnation refers to a persistent state of low economic growth and limited development, often characterized by poverty, low productivity, and limited access to essential services. Traditional economic theories often struggled to explain why some countries remained trapped in this state despite possessing resources. Harvey Leibenstein, in his seminal work, addressed this issue with the Critical Minimum Effort Theory (CME), proposed in the 1950s. This theory posits that a certain minimum level of investment is required to initiate and sustain economic growth, and that simply allocating resources isn’t enough; the *nature* of investment and the presence of complementary factors are crucial for breaking the cycle of stagnation.
Understanding the Critical Minimum Effort Theory
Leibenstein’s CME theory challenges the neoclassical assumption of diminishing returns to capital. He argued that in underdeveloped economies, returns to capital are initially *increasing* due to the existence of substantial underutilized capacity and the potential for positive externalities. However, this increasing return doesn’t automatically translate into sustained growth. A ‘critical minimum effort’ – a specific level and type of investment – is needed to trigger a self-sustaining process of economic development.
Components of the Critical Minimum Effort
1. Critical Minimum Investment
The core of the theory lies in the idea that a certain threshold of investment is required to overcome the initial inertia and unlock the potential for increasing returns. This investment isn’t merely about increasing the capital stock; it’s about reaching a point where the positive externalities outweigh the costs and inefficiencies associated with underdevelopment. This threshold varies depending on the specific context of the economy.
2. Social Overhead Capital (SOC)
Leibenstein emphasized the crucial role of SOC – infrastructure like roads, railways, ports, power plants, communication networks, and education/healthcare facilities. He argued that these are essential complements to direct productive investments. Without adequate SOC, the returns to direct investment are significantly diminished. For example, a new factory will be less productive if it lacks reliable transportation for raw materials and finished goods, or a skilled workforce.
3. The Entrepreneurial Gap
Perhaps the most unique aspect of Leibenstein’s theory is the concept of the ‘entrepreneurial gap’. He identified three types of entrepreneurs:
- Ordinary Entrepreneurs: Those who operate within existing market conditions and are motivated by existing profit opportunities.
- Discriminating Entrepreneurs: Those who perceive and exploit profit opportunities that others miss, often involving innovation and risk-taking.
- Creative Entrepreneurs: Those who actively *create* new profit opportunities by introducing new products, processes, or markets.
Leibenstein argued that underdeveloped economies suffer from a shortage of discriminating and, especially, creative entrepreneurs. These entrepreneurs are vital for identifying and capitalizing on the potential for increasing returns and for driving innovation. Closing this entrepreneurial gap is a key component of the CME.
The Process of Economic Take-Off
According to the CME, economic take-off occurs when the critical minimum effort is achieved. This leads to:
- Increased Returns to Investment: As SOC improves and entrepreneurial activity increases, the returns to investment rise.
- Positive Externalities: Investments generate positive externalities, benefiting other firms and industries.
- Self-Sustaining Growth: The increased returns and externalities create a virtuous cycle of investment and growth.
Criticisms and Limitations
Despite its insights, the CME theory has faced criticism:
- Difficulty in Quantification: Determining the ‘critical minimum’ level of investment and the size of the entrepreneurial gap is challenging in practice.
- Static Framework: The theory is relatively static and doesn’t fully account for dynamic changes in technology and global markets.
- Neglect of Institutional Factors: The theory doesn’t adequately address the role of institutions, governance, and political factors in economic development.
However, the CME remains a valuable framework for understanding the complexities of development and the importance of complementary investments and entrepreneurial activity.
Examples
South Korea’s Development: South Korea’s rapid economic growth in the 1960s and 70s exemplifies the CME. The government made substantial investments in SOC (infrastructure, education) alongside targeted investments in key industries, and actively fostered entrepreneurship. This created a virtuous cycle of growth.
Sub-Saharan Africa: Many countries in Sub-Saharan Africa have struggled to achieve sustained economic growth despite receiving significant foreign aid. This can be partly attributed to a lack of adequate SOC, a weak entrepreneurial base, and a failure to reach the critical minimum effort required for take-off.
Conclusion
Leibenstein’s Critical Minimum Effort Theory provides a nuanced understanding of the challenges faced by underdeveloped economies. It highlights the importance of not just the *amount* of investment, but also its *composition* – particularly the need for social overhead capital and a vibrant entrepreneurial ecosystem. While the theory has limitations, its emphasis on complementary factors and the entrepreneurial gap remains relevant for policymakers seeking to promote sustainable economic development. Addressing these factors is crucial for breaking the cycle of stagnation and achieving long-term growth.
