May 9, 2023 · In Book III of WN Smith identifies in history what he considers key factors promoting economic development and in Book IV the restraints on growth of mercantilist policies. The main purpose of this paper is to provide a concise exposition of Adam Smith’s theory of growth and economic development.
- Overview
- Economic growth
Smith’s analysis of the market as a self-correcting mechanism was impressive. But his purpose was more ambitious than to demonstrate the self-adjusting properties of the system. Rather, it was to show that, under the impetus of the acquisitive drive, the annual flow of national wealth could be seen to grow steadily.
Smith’s explanation of economic growth, although not neatly assembled in one part of The Wealth of Nations, is quite clear. The core of it lies in his emphasis on the division of labour (itself an outgrowth of the “natural” propensity to trade) as the source of society’s capacity to increase its productivity. The Wealth of Nations opens with a famous passage describing a pin factory in which 10 persons, by specializing in various tasks, turn out 48,000 pins a day, compared with the few pins, perhaps only 1, that each could have produced alone. But this all-important division of labour does not take place unaided. It can occur only after the prior accumulation of capital (or stock, as Smith calls it), which is used to pay the additional workers and to buy tools and machines.
The drive for accumulation, however, brings problems. The manufacturer who accumulates stock needs more labourers (since labour-saving technology has no place in Smith’s scheme), and, in attempting to hire them, he bids up their wages above their “natural” price. Consequently, his profits begin to fall, and the process of accumulation is in danger of ceasing. But now there enters an ingenious mechanism for continuing the advance: in bidding up the price of labour, the manufacturer inadvertently sets into motion a process that increases the supply of labour, for “the demand for men, like that for any other commodity, necessarily regulates the production of men.” Specifically, Smith had in mind the effect of higher wages in lessening child mortality. Under the influence of a larger labour supply, the wage rise is moderated and profits are maintained; the new supply of labourers offers a continuing opportunity for the manufacturer to introduce a further division of labour and thereby add to the system’s growth.
Here then was a “machine” for growth—a machine that operated with all the reliability of the Newtonian system with which Smith was quite familiar. Unlike the Newtonian system, however, Smith’s growth machine did not depend for its operation on the laws of nature alone. Human nature drove it, and human nature was a complex rather than a simple force. Thus, the wealth of nations would grow only if individuals, through their governments, did not inhibit this growth by catering to the pleas for special privilege that would prevent the competitive system from exerting its benign effect. Consequently, much of The Wealth of Nations, especially Book IV, is a polemic against the restrictive measures of the “mercantile system” that favoured monopolies at home and abroad. Smith’s system of “natural liberty,” he is careful to point out, accords with the best interests of all but will not be put into practice if government is entrusted to, or heeds, “the mean rapacity, the monopolizing spirit of merchants and manufacturers, who neither are, nor ought to be, the rulers of mankind.”
The Wealth of Nations is therefore far from the ideological tract it is often assumed to be. Although Smith preached laissez-faire (with important exceptions), his argument was directed as much against monopoly as against government; and although he extolled the social results of the acquisitive process, he almost invariably treated the manners and maneuvers of businessmen with contempt. Nor did he see the commercial system itself as wholly admirable. He wrote with discernment about the intellectual degradation of the worker in a society in which the division of labour has proceeded very far; by comparison with the alert intelligence of the husbandman, the specialized worker “generally becomes as stupid and ignorant as it is possible for a human being to become.”
In all of this, it is notable that Smith was writing in an age of preindustrial capitalism. He seems to have had no real presentiment of the gathering Industrial Revolution, harbingers of which were visible in the great ironworks only a few miles from Edinburgh. He had nothing to say about large-scale industrial enterprise, and the few remarks in The Wealth of Nations concerning the future of joint-stock companies (corporations) are disparaging. Finally, one should bear in mind that, if growth is the great theme of The Wealth of Nations, it is not unending growth. Here and there in the treatise are glimpses of a secularly declining rate of profit; and Smith mentions as well the prospect that when the system eventually accumulates its “full complement of riches”—all the pin factories, so to speak, whose output could be absorbed—economic decline would begin, ending in an impoverished stagnation.

What is Smith's contribution to economic development?
Adam Smith is known as father of economics. We get his ideas about economic development from his well-known book, “An Enquiry into the Nature and Causes of Wealth of Nations” (1976) which has tremendously influenced the thinking about economic growth and development.
Analysis of the process of economic growth was a central feature of the work of the English classical economists, as represented chiefly by Adam Smith, Thomas Malthus and David Ricardo.

- Division of labour. Smith’s theory of the division of labour has had a major influence on our understanding of how economies work. According to Smith, the key to increasing productivity is to divide labour into a series of repetitive tasks performed by different people.
- Labour theory of value. Adam Smith’s labour theory of value is one of the key concepts discussed in The Wealth of Nations. According to this theory, the value of a good or service is determined by the amount of labour that was required to produce it.
- Free market philosophy. In The Wealth of Nations, Smith put forth his philosophy of free markets, which argued that individuals pursuing their own self-interest would result in the best outcomes for society as a whole.
- Gross Domestic Product (GDP) The concept of GDP originated in Adam Smith’s writings on wealth and productivity. He argued that a country’s productivity is a result of its ability to accumulate capital through a series of interconnected markets.
Adam Smith’s theory of economic growth is at first sight startlingly different from that of Quesnay and the Physiocrats. In their argument industry produces no investable surplus, and therefore makes no positive contribution to growth, which depends entirely on...
Adam Smith and Economic Development: theory and practice. Adam Smith describes at least two models of economic development—the 4 stages of development model and the development of town and cities. The models present an unfolding view of economic growth from primitive to advanced stages. But Smith´s historical
