1-Page Summary of The Wealth of Nations

Overall Summary

Adam Smith was a Scottish philosopher, economist, and author. He wrote The Wealth of Nations and The Theory of Moral Sentiments. In his work on economics, he introduced the idea that in an unregulated economy free competition will result in the best allocation of resources.

The Wealth of Nations is an influential and important book, published in 1776. It was written during the Scottish Enlightenment but it also marks the beginning of the Industrial Revolution. The book explains why some countries are wealthier than others and introduces economic principles that are still applicable today. Smith argues against mercantilism, a system where government controls trade to gain wealth for its country, instead advocating free markets and laissez-faire economics (a system where government does not interfere with business).

The Wealth of Nations is divided into five books. In Book 1, Smith establishes his basic theories that become the groundwork for his later analysis. He introduces the concepts of price, stock and division of labor. He also asserts that a nation’s wealth is not comprised of money but rather money is a method to store and exchange commodities and labor which are actually comprised of goods and services. The components of any price not paid to workers or landlords are deemed profit.

In Book 2, Smith discusses stock. He defines it as the assets used in a commercial endeavor. Smith bifurcates stock into capital and revenue, and asserts that societies should maintain more of their stock to be invested in productive endeavors rather than spent on unproductive ones. He also differentiates between home trade (domestic commerce) and foreign trade of consumption (the carrying trade). Because money can move through domestic commerce more frequently, there is greater wealth created than in the carrying trade because goods are exchanged less frequently.

Smith’s book has three parts. The first part is about the history of economic systems, and Smith concludes that a natural economic system (in which agriculture is predominant) should be preferred over other models.

Adam Smith argues against mercantilism in Book 4. Mercantilism is an economic system that seeks to grow a nation’s wealth and power by encouraging exports while restricting imports. The objective was to bring as much gold and silver into the country as possible, which would increase employment at home. However, Smith concludes that this system costs more than it brings back in revenue, so he suggests abandoning the system of mercantilism for domestic trade because it produces more wealth.

In Book 5, Smith argues that certain costs of governance are necessary and unavoidable. However, he also suggests that Britain’s national debt at the time was spiraling out of control. He proposes either a commodity tax or abandoning Britain’s American colonies because they were constantly draining resources from the treasury.

Book 1, Chapter 1: “Of the Division of Labour”

Smith argues that division of labor is the key to economic efficiency. The basic idea behind it is that people who do one thing well can be more productive than those who do everything poorly. This concept applies to trades, and Smith illustrates his point by talking about how pin production could increase if there were specialized workers doing just one task over and over again (such as making the head or the body). He then extends this theory to include divisions of labor between trades, which would make a country’s economy much more efficient.

The division of labor has three major effects. First, it makes workers more efficient by giving them repetitive tasks to do so they can become experts at their jobs. Second, the division of labor saves time because workers don’t have to move around as much and can get right to work on their task. Third, specialized machines are created when there is a need for them in order to make manufacturing more efficient.
