Absolute Convergence: Do Developing Countries Catch Up to Developed Ones?

Absolute convergence is an economic theory that sparks debate: Can developing countries eventually reach the same level of economic output per person as developed countries? This concept hinges on the idea that developing economies have a key advantage—a lower ratio of capital per worker. Let’s delve deeper and explore the theory of absolute convergence, its core arguments, and why it might not be as straightforward as it seems.

Understanding absolute convergence

Absolute convergence is a thought-provoking theory in economics that asks a crucial question: will developing countries eventually reach the same level of economic output per person (income per capita) as developed countries? This theory hinges on a key factor – capital per worker.

Imagine a factory with a limited number of machines compared to its workforce. This scenario represents a developing country with a low capital-per-worker ratio. In economic terms, capital refers to physical assets like machinery, buildings, and infrastructure. When there are fewer machines (capital) for each worker, each additional machine has a significant impact on productivity. This is where the magic of absolute convergence comes in.

Core principle

Developing countries, with their lower capital per worker ratio, are believed to have a higher marginal productivity of capital. This means that each new unit of capital (like a new machine) will generate a larger increase in output in a developing country compared to a developed country that already has a lot of capital.

In simpler terms, because developing countries are starting with less capital, each new investment has a bigger impact. This theoretically translates to faster economic growth, allowing developing countries to eventually catch up to developed ones in terms of income per capita. This is the core principle of absolute convergence – the idea that developing economies have the potential to leapfrog over developed ones due to their lower capital starting point.

The theory of absolute convergence

Absolute convergence hinges on the relationship between capital per worker and marginal productivity of capital. Let’s break it down:

• Capital per worker: Imagine a factory with a limited number of machines compared to its workforce. This scenario represents a developing country with a low capital-per-worker ratio.
  
• Marginal productivity of capital: This refers to the additional output generated by adding one more unit of capital (like a new machine) to the production process.

Here’s the key insight: because developing countries have fewer machines per worker, each additional machine has a bigger impact on overall productivity. Think of it like adding fertilizer to a field. If the soil is already very fertile (which represents a developed country with a lot of capital), adding a little more fertilizer won’t have a huge effect. But in a less fertile field (developing country with low capital), the same amount of fertilizer can significantly boost crop yield (economic output).

This translates to a higher marginal productivity of capital for developing countries. In simpler terms, each new investment in machinery or infrastructure has a bigger impact on the economy compared to a developed country that already has a lot of capital.

The predicted outcome: convergence

Based on this principle, the theory of absolute convergence predicts that developing countries will experience faster economic growth due to their higher marginal productivity of capital. Over time, this faster growth should eventually lead to a convergence in income levels between developed and developing countries. Imagine two runners on a track – the developing country starts behind but has the potential to close the gap (catch up) due to its faster running speed (higher growth).

However, as we’ll explore later, the theory of absolute convergence isn’t without its critics. While it offers a compelling explanation for potential catch-up, it doesn’t account for all the factors influencing economic growth.

Challenges to absolute convergence: Why catch-up might be tougher than expected

The theory of absolute convergence paints a promising picture, but the road to catching up for developing countries might not be as smooth as it seems. Here’s why:

Beyond capital: Total factor productivity (TFP)

Absolute convergence focuses heavily on capital per worker. However, economic growth is driven by more than just physical assets. A crucial factor often overlooked is Total Factor Productivity (TFP).

Imagine two factories with the same amount of capital (machines) but different levels of efficiency. The factory with better TFP utilizes its resources more effectively, producing more output with the same amount of input. This could involve advancements in technology, innovation, or better management practices.

Developed countries often have a significant advantage in TFP. They invest heavily in research and development, leading to continuous technological advancements that improve efficiency and productivity. This creates a moving target for developing countries. Even if they’re catching up in terms of capital per worker, developed economies are constantly pushing the boundaries of TFP, making it harder to narrow the gap.

While absolute convergence is a fascinating theory, empirical evidence paints a more complex picture. Many developing countries haven’t been converging on developed economies as quickly as the theory predicts. This suggests that factors beyond capital per worker play a more significant role in economic growth.

Limitations of the theory

• Focus on capital: The theory overemphasizes the importance of capital per worker, neglecting the impact of TFP advancements in developed countries.
• Ignores other factors: It doesn’t account for other crucial factors like institutions, political stability, and access to education, which can significantly influence economic growth.

In conclusion, absolute convergence offers a valuable concept, but it’s important to recognize its limitations. The path to economic prosperity for developing countries is multifaceted, requiring investment in capital, fostering innovation, and building a strong foundation for overall economic development.

Beyond absolute convergence: A multifaceted approach

While absolute convergence sheds light on the potential of developing economies, it’s crucial to recognize that achieving sustained economic growth requires a multifaceted approach. Here’s why:

Capital accumulation

While the theory might downplay the role of capital, accumulating capital remains essential for developing countries. Investments in infrastructure, like reliable transportation networks and efficient power grids, combined with investments in modern machinery and technology, provide the physical tools needed to boost productivity.

Think of it as building a strong foundation (infrastructure) and equipping that foundation with the latest tools (technology) to maximize efficiency. This comprehensive approach to capital accumulation allows developing economies to not only move goods and services efficiently but also produce them at a competitive rate.

Looking beyond capital: The crucial ingredients for economic growth

However, the story doesn’t end there. To truly thrive, developing economies need to focus on factors beyond just capital accumulation:

• Technological advancements and innovation: Empowering innovation and fostering technological progress are crucial for long-term growth. Developed countries often have a head start in research and development. Developing countries can bridge this gap by investing in education, attracting skilled talent, and fostering a culture of entrepreneurship.
• Human capital development: A skilled and educated workforce is the engine that drives innovation and effectively utilizes technology. Investments in education and training programs equip individuals with the skills needed to contribute to a growing economy.
• Institutional reforms: Strong institutions, like a well-defined legal system and secure property rights, create a stable environment for businesses to operate and invest. This fosters trust, encourages entrepreneurship, and attracts foreign investment – all crucial ingredients for economic growth.

The Takeaway

Absolute convergence offers a valuable lens for understanding economic development. However, for developing countries to achieve sustained growth and narrow the gap with developed nations, a more comprehensive approach is necessary. This includes accumulating capital, fostering innovation, investing in human capital, and building strong institutions. By addressing these multifaceted elements, developing economies can pave the way for a brighter and more prosperous future.
