Scottish philosopher (1723–1790) whose Wealth of Nations founded modern economics by explaining how markets and specialization create wealth.
See it on the Money & Finance map →How it works
Published in March 1776, the book opens in a pin factory: ten workers, each doing one step, made about 48,000 pins a day, where one alone could not make 20, perhaps not even one. Smith argued a nation's wealth is what it produces, not the gold it hoards, attacking mercantilism. Self-interest, checked by competition, serves the public: 'It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner.' He also warned that merchants conspire to raise prices.
Why it matters
He gave free markets and free trade their founding argument, and his attack on hoarding gold and shielding home industries still frames tariff debates.
Legacy
His two books, The Theory of Moral Sentiments (1759) and The Wealth of Nations, plus students' notes of his Glasgow lectures. He appeared on the Bank of England's £20 note, 2007–2022.
Debates and risks
His lone 'invisible hand' line in The Wealth of Nations is narrower than its modern use; scholars debate how pro-market his wider moral philosophy really was.
Connections (3)
▸Adam Smith and The Wealth of Nations (1776) gave the classic account of Markets, prices, supply and demandFact, law or data
The connection
Smith explained how prices coordinate strangers without a planner. When a good is scarce, its market price rises above its 'natural price', drawing in producers; in a glut, prices fall and producers leave. Pursuing their own gain, people are 'led by an invisible hand' to serve the public, he wrote, a phrase he used only once in the book.
When and why
Written mostly in Kirkcaldy, Scotland, and finished and published in London in 1776; prices are in Book I, chapter 7, the invisible hand in Book IV.
How we know
The text itself, and its heirs: from Ricardo to Alfred Marshall, who popularized the modern supply-and-demand diagram in 1890, economists built directly on it.
Debates and risks
Scholars dispute what Smith meant by the invisible hand, which in context concerned investors preferring domestic industry, not markets in general.
▸Adam Smith and The Wealth of Nations (1776) laid groundwork for Comparative advantage and free trade (Ricardo)Fact, law or data
The connection
Smith argued countries should buy what others make more cheaply, an idea now called absolute advantage. Ricardo, who read The Wealth of Nations in 1799, went further: trade pays even for a country that is better at everything, as long as relative costs differ. Smith's case against mercantilist tariffs gave Ricardo his starting point.
When and why
Smith in 1776; Ricardo, a London stockbroker turned economist, published his version in 1817, four decades later.
How we know
Ricardo named Smith as his main influence, and his Principles engages Smith's theories of value and trade from its opening pages.
Debates and risks
Who first stated comparative advantage, Ricardo, Robert Torrens (1815) or James Mill, is debated by historians of economic thought.
▸Marxian economics (Karl Marx, Das Kapital) critiqued the classical ideas of Adam Smith and The Wealth of Nations (1776)Fact, law or data
The connection
Marx took the labor theory of value from Smith and Ricardo, the 'classical' economists, and turned it into a critique: if labor creates value, profit must come from unpaid labor. Where Smith saw the division of labor and markets enriching everyone, Marx saw them alienating workers and concentrating wealth in owners' hands.
When and why
Marx studied Smith and Ricardo in Paris and London from the 1840s to the 1860s; his Theories of Surplus Value examines them at length.
How we know
Das Kapital is subtitled 'A Critique of Political Economy', and it engages Smith repeatedly, by name.
Debates and risks
Scholars argue whether Smith's own worry that repetitive factory work dulls workers anticipated Marx's idea of alienation.
