And yet an increase in the price of pencils involves a series of coordinated responses to market signals spanning industries, continents, and hundreds of thousands of people—a group of which you, without realizing it, are part. None of the individuals and companies involved fully understand the process they are a part of, because it’s larger than any one person could fathom. That immense organizing property of the free market was most famously described by Scottish economist and philosopher Adam Smith, who called it an “invisible hand.”
His book The Wealth of Nations , published in 1776, an auspicious year for all things revolutionary, explored for the first time ideas of specialization and self-interest that would become foundational in the field of economics. Smith used the term “invisible hand” only once in the book’s 900-odd pages, but economists say the underlying concept is vital to his work.
“If you read [Smith’s] work … it’s all about what we would now call the invisible hand,” Eamonn Butler, director of the Adam Smith Institute, a policy think tank, told The Dispatch . “In other words, how does our individual action affect society?”
Smith used the metaphor in a section about why a rich man might choose to invest in his own community. “By preferring the support of domestic to that of foreign industry, he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention.”
The idea that self-interested behavior could contribute to the common good went against the prevailing economic wisdom of Smith’s time, particularly on the subject of trade. The prevailing economic system in the 18 th century was mercantilism, under which nations aimed to increase their wealth through a favorable balance of trade, aided by import quotas and tariffs. Thus, only the side that increased its stock of gold and silver—usually the exporter—was viewed as benefiting from a trade agreement. To build wealth, the great powers of the 18 th century waged wars of conquest and heavily restricted the economic freedom of their subjects, as Britain did in preventing the American colonies from trading with other countries.
But Smith, after traveling across Europe and noting the ways in which the Industrial Revolution had transformed every nation’s economy, came to the conclusion that trade was more than just an exchange of wealth—it actually created wealth. “Smith completely demolished the mercantilist idea that in international trade there’s a winner and a loser,” Butler said. “Adam Smith said, ‘No, that’s not true. Both sides can benefit from the exchange.’”
As such, Smith was instrumental in bringing about our modern era of free trade. But since his time, the ideas in The Wealth of Nations , and in particular the invisible hand, have become synonymous with capitalism more generally. Free market economists like Milton Friedman referred to the concept as “cooperation without coercion” and made the invisible hand a foundational piece of economic theory.
Meanwhile, critics attacked the idea that the invisible hand organized the market in the best possible way. Karl Marx facetiously compared the invisible hand to “the fate of the ancients”: an outdated, capricious system without concern for human welfare. He and many of the Marxian economists who came after him, such as Oskar Lange and Abba Lerner, argued that the government could more effectively control the market and steer it toward what was best for the people.
It was in this context of renewed distrust in the free market that economists like Ludwig von Mises and Friedrich A. Hayek mounted a new defense of Adam Smith’s theories. Most notably, in a 1945 essay called “ The Use of Knowledge in Society ,” Hayek illustrated how the invisible hand works in modern, complex, and decentralized markets.
To understand Hayek’s idea, it’s helpful to have an example. Economist Russ Roberts uses a scenario involving the market for graphite, a raw material supplied only by companies that mine it and purchased only by makers of pencils and tennis rackets. Suddenly, a new use of graphite is discovered: Graphite powder stabilizes friction and reduces heat buildup in brake pads. Now car manufacturers want graphite, and a lot of it. They enter the market, but the mining companies have only enough raw material to supply the pencil and racket manufacturers.
Socialists viewed the answer from here as simple—appoint someone, a hypothetical “graphite commissioner,” to decide which allocation of graphite best benefits everyone. But Hayek pointed out that anyone in such a position would need…
