Explain to what extent the neoclassical growth theory (e.g. Solow Swan model) that emphasize capital accumulation and total factor productivity can explain the East Asian growth ‘miracles’ with particular references to the growth experiences of Korea and Singapore. Illustrate your answer with the aid of an appropriate model diagram(s).

The Neoclassical growth theory, particularly the Solow-Swan model, has been a fundamental framework in understanding the economic growth of countries. This model emphasizes the role of capital accumulation and total factor productivity (TFP) in driving economic growth. The East Asian growth 'miracles', particularly the experiences of Korea and Singapore, can be largely explained by this theory.

1. Capital Accumulation: The Solow-Swan model posits that sustained economic growth can be achieved through capital accumulation. Both Korea and Singapore have experienced significant capital accumulation during their growth periods. For instance, Korea invested heavily in education and infrastructure, leading to a substantial increase in its capital stock. Similarly, Singapore attracted massive foreign direct investment, which contributed to its capital accumulation. This aligns with the Solow-Swan model's prediction that an increase in capital leads to economic growth.

2. Total Factor Productivity (TFP): The Solow-Swan model also emphasizes the role of TFP, which measures the efficiency with which inputs are used in the production process. Both Korea and Singapore have shown significant improvements in TFP. For example, Korea's rapid industrialization and technological advancements have led to more efficient use of its resources. Similarly, Singapore's focus on high-tech industries and its efficient use of labor and capital have boosted its TFP.

3. Model Diagram: In the Solow-Swan model diagram, the steady-state level of capital per worker is where the investment per worker (s*f(k)) equals the break-even investment (δk + nk), where s is the savings rate, f(k) is the production function, δ is the depreciation rate, and n is the population growth rate. An increase in the savings rate or a decrease in the population growth rate shifts the investment per worker curve upwards, leading to a higher steady-state level of capital per worker and thus higher output per worker. This illustrates how capital accumulation can lead to economic growth.

However, it's important to note that the Solow-Swan model cannot fully explain the East Asian growth miracles. The model assumes that economies eventually converge to a steady-state growth rate, which is determined by the rate of technological progress. But in reality, the growth rates of Korea and Singapore have not converged to the rates of more advanced economies. This suggests that other factors, such as institutional factors, government policies, and cultural factors, also play a crucial role in their economic growth.
