Adam Smith is the father of economics. He is remembered as the greatest classical economist. He published his book, "An Inquiry into the Nature and Causes of the Wealth of Nations," in 1776. This book established a basis for current economic theories that analyze economic development. The theory of Adam Smith somehow influences the Policies of the Government to date. Adam Smith's economic development theory was mainly based on the supplies of an economy. The Supply-Side Driven Model of Development As we discussed earlier The model of Economic Development Proposed by, Adam Smith is mainly focused on the supply Side. Let us try to understand this by this basic production function. Y = f ( L, K, T) where:Y = 'Output'L = 'Labor'K = 'Capital'T = 'Land' According to Adam Smith, the output depends on these inputs: Labor Capital Land In this regard, he supported the 'Laissiez-Faire policy', arguing that the Government should stay out of the market functions, as much as possible. This was the model that highlighted that the primary engine of economic development is the supply side of the economy. Key Components of Smith's Economic Development Theory 1. Population Growth According to Adam Smith, the growth of the population was endogenous, It means that it was influenced by internal factors only and not by external factors. During his life period, the development of the economy depended on the available resources that support an increasing workforce. This means the more resources available, the more the population could grow. Now, It creates a cycle where economic development is supposed to support a larger population, and the well-developed population will further contribute to economic development. 2. Investment According to Smith, investment was also endogenous and determined by the rate of savings of capitalists. The reinvestment of savings into productive activities was considered important for economic development. Also, The process of saving and reinvestment was necessary for capital gain, which in turn rose to economic development. An increased rate of savings will lead to more amount of investment in the economy. 3. Land Growth Adam Smith argued that land resources could grow by taking over new territories, like through colonization, or by using new tech to make existing lands more fertile. Getting new lands gave people more resources and chances to do business. Also, better farming methods and tools could make land more productive leading to more effective food production and use of resources. 4. Technological Progress People saw tech progress as a key part of overall economic development. Smith's well-known idea about dividing work, or having people do specific jobs, stressed that breaking down how things are made into special tasks led to better output and growth. Tech advances helped this job split by giving workers better tools and machines, which in turn boosted how much they could make. As tech kept getting better, it not only made how things were made more effective but also created new ways for business and development to happen. Factors of economic development Division of Labor People saw tech progress as an important factor in overall economic development. Adam Smith's well-known idea about people pursuing specific jobs proved that specialization in specific work leads to efficiency and also an increase in output. Also, advancement in technology helped this job split by giving workers better tools and machines, which in turn boosted their incomes. As tech kept getting better, it not only improved the effective process of production but also created new ways for business and growth to happen. Improvements in Machinery Smith also highlighted the significance of machine improvements. Better tools and tech boost output and allow more job specialization in industries. Upgraded machines help finish tasks quicker and more, cut expenses, and raise production. These upgraded machines played an important role in industrialization and mass production during the Industrial Revolution. International Trade Adam Smith pointed out Global trade was another vital growth driver. Nations could focus on making specific goods by trading. Trade lets countries concentrate on what they make best while buying cheaper items from other places. This exchange helps all trading nations leading to more wealth and economic development. Assumption of Perfect Competition Smith assumed that markets are in perfect competition where many small companies can compete easily. Thus no single firm can control prices. He thought that it was crucial to use resources and boost the economy. In a perfect competition market, resources are used fully, and prices are determined as real costs of production. This results in the best distribution of goods and services making society better off overall. Conclusion Adam Smith's theory of economic development established a base for classical economics. It also influences modern economic thought. His views about the roles of labor, capital, land, technological progress, and other things created a basic framework for understanding economic development. He talked about the idea of less government intervention in the economy and the need for free markets. His ideas continue to shape economic growth strategies today. Smith pictured a market that regulates itself driven by people's interests. He theoretically elaborated on how new ideas, commerce, and smart use of resources play key roles in long-term economic growth. Frequently Asked Questions 1. Who is Adam Smith and why his theories are so important in economics? Adam Smith is the father of economics. He is a famous classical economist. His famous book, "An Inquiry into the Nature and Causes of the Wealth of Nations," was the base for 'modern economic thoughts'. Today's modern economic practices and policies are somehow determined by considering his theories as a base 2. How does Adam Smith's production function relate to economic development? Smith's production function, Y= f (L, K T), demonstrates the connection between output (Y) and the utilization of labor (L), capital (K), and land (T). Understanding how these inputs are combined and utilized effectively provides insights into how economic development is achieved. 3. What role does population development play in Smith's theory? In Smith's theory, population development is endogenous and depends on the sustenance available to support an increasing workforce. Economic development can support a larger population, which in turn contributes to further economic development. 4. How does investment influence economic development according to Adam Smith? Investment plays a key role in advancing the economy. Savings from business owners, go back into productive work. This leads to more capital and further economic growth. 5. What is the significance of land development in Smith's theory? Smith proposed that land development could happen by taking new territories or by using new methods to make existing lands more fertile. Expanding and improving land resources contributes to economic progress.
