Six Theories That Built and Broke Markets: From Colbert's Treasury to Friedman's Chicago, How Six Rival Visions of the Economy Shaped Empires, Crashes, and Daily Life
Europe, c. 1500–1750 • The Doctrine That Built Empires
For 250 years, the dominant European economic doctrine held that national wealth equaled the gold and silver in the king's vaults. Exports good, imports bad. Colonies were a captive market and supply of raw materials, while domestic industry needed protection by tariffs, subsidies, and royal monopolies. Under Jean-Baptiste Colbert in France and the East India Companies in England and the Netherlands, mercantilism built the modern colonial empires — and the modern customs office.
1619–1683 • Controller-General of Finances under Louis XIV
The son of a draper from Reims who rose to become the most systematic mercantilist of all time. From 1665 he tripled French royal revenues, founded state manufactures (Gobelins tapestries, Saint-Gobain glass), built the French navy from 18 to 270 ships, and chartered the French East India Company. "Colbertisme" became a byword for state-led industrial policy.
Director of the East India Company. England's Treasure by Forraign Trade was mercantilism's English bible, published 23 years after his death.
French playwright and political economist. Coined the phrase "économie politique" in his 1615 Treatise on Political Economy.
Director-General of the Dutch East India Company in Batavia. Engineered the Spice Islands monopoly with brutal force in 1621.
Pioneered "political arithmetic" — the use of statistics for economic policy. Bridged late mercantilism and early classical thought.
Mercantilism is the antithesis of every later school in viewing wealth as zero-sum: my surplus is your deficit. Smith demolished this; Marxists agreed wealth came from production not exchange but located it in labor. Yet today's "trade war" rhetoric and industrial policy debates show mercantilist intuitions are far from dead.
Britain, 1776–1870 • Smith, Ricardo, Mill, and the Birth of Free Markets
On March 9, 1776 — four months before the American Declaration of Independence — a Scottish moral philosopher published An Inquiry into the Nature and Causes of the Wealth of Nations. Adam Smith argued that the pursuit of self-interest, mediated by free competitive markets, generates the wealth of all. Through the work of Ricardo, Malthus, James and John Stuart Mill, classical economics dismantled mercantilism, justified free trade, and gave Victorian Britain its ideology of laissez-faire.
1723–1790 • Scottish moral philosopher, Glasgow professor
The shy, absentminded son of a Kirkcaldy customs official. Tutored a young duke on a Grand Tour, met Voltaire, Quesnay, and Turgot in France, and returned to spend a decade writing The Wealth of Nations. He never married, lived with his mother until her death, and ended his career as — ironically — Commissioner of Customs for Scotland.
Stockbroker who made a fortune speculating on Waterloo bonds, retired at 42, and rewrote economics. Discovered comparative advantage.
Anglican clergyman and Britain's first professor of political economy. Published anonymously at 32; the Essay on Population grew into six editions.
Educated by his father from age three (Greek at three, Latin at eight). Wrote on economics, logic, liberty, and women's suffrage; MP from 1865.
French popularizer of Smith. Say's Law — "supply creates its own demand" — would become Keynes's chief target a century later.
Classical economists shared with mercantilists a focus on production rather than utility, but located wealth in labor and capital, not gold. Marx took the labor theory of value to socialist conclusions Smith would have rejected. Marginalists in the 1870s discarded the labor theory altogether for subjective utility — the foundation of all subsequent micro.
Europe, 1867– • Surplus Value, Class Struggle, Inevitable Crisis
Karl Marx, exiled in London, spent 18 years in the British Museum Reading Room writing Das Kapital. Volume I appeared in 1867. Borrowing the labor theory of value from Smith and Ricardo, Marx argued capitalism systematically extracts surplus value from workers, generating both the engines of growth and the seeds of recurrent crisis. After 1917 his ideas governed a third of the world's population. Today, despite the fall of the Soviet Union, Marxist economics remains a serious analytical tradition.
1818–1883 • Philosopher, journalist, exile in London
Born to Jewish parents who converted to Lutheranism in Trier. Doctorate in philosophy at 23. Editor of Cologne's Rheinische Zeitung until censorship closed it in 1843. Exiled successively to Paris, Brussels, and London, where Engels supported him while he toiled in the British Museum. Buried in Highgate Cemetery, where his tomb still draws pilgrims.
Wealthy Manchester mill manager. Co-author of the Manifesto, financier of Marx, editor of Volumes II and III of Capital after Marx's death.
Imperialism: The Highest Stage of Capitalism (1916). Adapted Marxism for an agrarian, semi-developed Russia — against Marx's own predictions.
The Accumulation of Capital (1913). Argued capitalism requires non-capitalist peripheries. Murdered by proto-fascist Freikorps in Berlin.
Cambridge economist who edited Ricardo's works and revived Marxian value theory through Production of Commodities by Means of Commodities (1960).
Marxist economics shares the labor theory of value with Smith and Ricardo but turns it into a critique of capitalism rather than a justification. Where Keynesians fix capitalism through demand management, Marxists argue its crises are structural and unsustainable. Austrians treat both Marx and Keynes as fatal conceits about state planning.
Cambridge & Bretton Woods, 1936– • Saving Capitalism From Itself
In February 1936, with the world still mired in the Great Depression, John Maynard Keynes published The General Theory of Employment, Interest and Money. Where classical economics held that markets self-correct to full employment, Keynes argued that depressed economies could remain stuck below capacity and required active fiscal stimulus from government. The book founded macroeconomics, justified the New Deal post-hoc, and shaped Western economic policy for forty years.
1883–1946 • King's College Fellow, Treasury official, Bloomsbury figure
Son of an economist (John Neville Keynes). Eton, King's College, Cambridge. Bursar of King's, where he made the college rich speculating on commodities and currencies. Bloomsbury bisexual who married a Russian ballerina (Lydia Lopokova) in 1925. Negotiated the British post-war loan in 1945–46 and helped design the IMF and World Bank at Bretton Woods.
Cambridge economist, Keynes's Circus member. The Economics of Imperfect Competition (1933). Founded post-Keynesian economics.
Author of the bestselling textbook Economics (1948). First American Nobel in Economics (1970). Synthesized Keynes with neoclassical micro.
Nobel 1981. Tobin's q, portfolio theory, and the Tobin tax on currency speculation. Yale's leading Keynesian.
"Stability is destabilizing." His financial-instability hypothesis was rediscovered after the 2008 crisis as the "Minsky Moment."
Keynes accepted classical economics for full-employment situations but rejected Say's Law. Where Marxists saw capitalism as terminally unstable, Keynes saw it as repairable through state demand management. Austrians (Hayek) and Monetarists (Friedman) attacked Keynesian fine-tuning as inflationary and naive about state knowledge — the great post-war debate.
Vienna to Chicago, 1871– • Markets as Discovery, Not Design
Founded by Carl Menger in 1871 with the publication of Principles of Economics, the Austrian School emphasized subjective value, methodological individualism, and the indispensable role of price signals in coordinating dispersed knowledge. Through Mises, Hayek, and Schumpeter, Austrians waged the great mid-century debate against socialist planning, won the Nobel for Hayek in 1974, and inspired the libertarian-conservative resurgence of the 1980s and beyond.
1899–1992 • LSE, Chicago, Freiburg professor; Nobel 1974
Vienna-born aristocrat (Friedrich August von Hayek). Studied under Wieser; emigrated to LSE in 1931 where he debated Keynes. The Road to Serfdom (1944) made him a public figure. Founded the Mont Pelerin Society in 1947 to revive classical liberalism. Won the Nobel jointly with Gunnar Myrdal in 1974. Lived to see his ideas vindicated by the fall of the Berlin Wall.
Founder of the school. Vienna University professor. Tutored Crown Prince Rudolf in economics; the prince later died at Mayerling.
Brilliant, irascible, and uncompromising. Fled the Nazis to New York, where he taught at NYU until his eighties. Human Action (1949).
Briefly Austria's finance minister; Harvard professor 1932–50. Coined "creative destruction" in Capitalism, Socialism and Democracy (1942).
NYU emeritus. Synthesized Mises and Hayek into entrepreneurial discovery theory: the entrepreneur as alert to disequilibrium opportunities.
Austrians share with Classical economists a faith in markets but ground it in subjectivism rather than labor value. Against Marx, they argue prices, not labor, encode value. Against Keynes, they argue depressions are necessary corrections to monetary expansion, not failures of demand. Against Friedman they reject macroeconomic aggregates and statistical macroeconomics tout court.
Chicago, 1956– • Friedman, the Money Supply, and the Conservative Counter-Revolution
Milton Friedman, born to immigrant Brooklyn dressmakers, transformed mid-century economics from his perch at the University of Chicago. With Anna Schwartz he wrote the monumental Monetary History of the United States (1963), arguing that the Great Depression was caused not by capitalism's failure but by the Federal Reserve's. Friedman's conviction that "inflation is always and everywhere a monetary phenomenon" reshaped central banking from the Volcker disinflation onward.
1912–2006 • University of Chicago professor; Nobel 1976
Born in Brooklyn to Hungarian-Jewish immigrants. PhD from Columbia. Joined Chicago in 1946 with his wife Rose Director Friedman. Together they wrote Free to Choose (1980), turned into a 10-part PBS television series watched by millions. Advised Pinochet's Chile, briefly and controversially, in 1975. The dominant policy economist of the late 20th century.
NBER economist; Friedman's co-author. The empirical workhorse behind A Monetary History. Active researcher into her nineties.
Chicago School Nobel 1995. Rational expectations critique made monetarism more rigorous and undermined naive Keynesian fine-tuning.
Swiss-American economist. With Allan Meltzer founded the Shadow Open Market Committee, monetarism's policy critique of the Fed.
Tall, cigar-chomping Fed Chair (1979–87) who broke 1970s inflation. Not a monetarist by temperament but applied the doctrine ruthlessly.
Monetarism shares with Austrians a focus on money, but accepts statistical macroeconomic methods Austrians reject. Against Keynesians, Friedman argued fiscal stimulus is impotent in the long run; only monetary policy matters. The Volcker-era convergence of monetarism, rational expectations, and inflation targeting effectively ended the post-war Keynesian consensus.

Smith wrote on the eve of the Industrial Revolution; Marx during the railway booms and busts; Keynes during the Great Depression; Friedman during the 1970s stagflation. Every paradigm shift in economics follows an event the existing theory cannot explain.
The deepest disagreement is epistemic: how much can a planner know? Mercantilism and Keynesianism trust state knowledge; Austrians and Monetarists deny it. Marxists believe collective democratic planning could supply what individual capitalists cannot.
Mercantilism reigned 1500–1776; Classical liberalism 1776–1929; Keynesianism 1936–1979; Monetarism / neoliberalism 1979–2008; pluralism since. Each lasts roughly two generations before crisis discredits it.
Almost every school is anchored in one defining work: Wealth of Nations, Capital, General Theory, Road to Serfdom, Capitalism and Freedom. Theoretical economics, despite its mathematics, is more text-bound than most physical sciences.
The Sveriges Riksbank Prize (1969–) recognized Friedman, Hayek, Samuelson, Tobin, Sen, Krugman, Stiglitz, and dozens more. The Nobel reshaped the prestige economy of academic economics — and entrenched neoclassical synthesis at its core.
WTO trade flows since 1995, the 2008 crisis, COVID-era stimulus, and 2022 inflation have all tested every school. None has emerged unscathed; pluralism, behavioral economics, and complexity-economics now compete with the older schools.
