Step-by-step explanation:
The Clarke-Fisher model, also known as the Clarke-Fisher evolutionary model, is an economic framework that explains the structural transformation of an economy as it develops. It was initially proposed by economists Colin Clark and Simon Kuznets in the mid-20th century. While the model has not undergone any direct updates or revisions since its inception, it has been further developed and expanded upon by subsequent researchers to incorporate new insights and empirical observations. Let's explore the evolution of the Clarke-Fisher model and illustrate it with examples.
The Clarke-Fisher model consists of three sectors: primary, secondary, and tertiary. The primary sector includes activities related to agriculture, forestry, fishing, mining, and other raw material extraction. The secondary sector encompasses manufacturing and industrial activities, while the tertiary sector comprises services such as transportation, finance, education, healthcare, and tourism.
Initially, the Clarke-Fisher model depicted the process of economic development as a movement of labor and resources from the primary sector to the secondary sector. This shift was driven by increasing productivity and technological advancements in agriculture, leading to a surplus of labor that could be absorbed by the expanding manufacturing sector. This transition was observed in many developed countries during the industrial revolution. For example, in the United Kingdom during the 18th and 19th centuries, there was a significant shift of labor from agriculture to manufacturing as the textile industry boomed.
However, subsequent research and empirical evidence challenged the simplicity of this unidirectional shift from primary to secondary sectors. Economists realized that the process of structural transformation is more complex and involves multiple interrelated factors. One of the key factors is the role of the services sector.
The services sector, or the tertiary sector, was initially considered as a residual sector that would expand once the primary and secondary sectors matured. However, it was later recognized that the services sector can undergo significant growth even during the early stages of development. For instance, the rise of financial services, telecommunications, and information technology has been observed in many developing economies. Countries like India and the Philippines have experienced substantial growth in their IT and business process outsourcing (BPO) industries, which have become major contributors to their economies.
Additionally, the evolution of the Clarke-Fisher model has incorporated the concept of deindustrialization in developed countries. Deindustrialization refers to the declining share of the secondary sector in the economy, often accompanied by the growth of the services sector. Many advanced economies have witnessed a shift away from manufacturing towards services and knowledge-based industries. This shift is driven by factors such as automation, globalization, and the increasing importance of intangible assets like intellectual property. For example, countries like the United States and the United Kingdom have seen a decline in manufacturing jobs but a rise in high-value services like finance, software development, and creative industries.
In summary, while the Clarke-Fisher model itself has not been revised, its understanding and application have evolved over time. The model now recognizes the importance of the services sector, the early growth of services in developing economies, and the phenomenon of deindustrialization in advanced economies. These developments reflect the dynamic nature of economic transformations and highlight the need for a more nuanced and comprehensive approach to understanding the structural changes in an economy.
