Unlike the schools already described (classical, neoclassical, and Austrian), the Chicago School is not a heterodox school, but a hyper-empirical and free-market branch within the mainstream (mainstream here means the Neoclassical school of economics).
It was born at the University of Chicago (USA) and represents the most pro-market and anti-Keynesian wing of twentieth-century orthodox economic thought. Its implicit motto is: “empirical evidence above all” and “markets work better than the State.”
1. Origins and key thinkers
| Generation / Period | Main thinker | Key work | Fundamental contribution |
|---|---|---|---|
| Precursors (1930s–50s) | Frank Knight Jacob Viner |
Risk, Uncertainty and Profit (1921) | Emphasis on uncertainty, price as signal, and critique of socialism. |
| Golden age (1950s–80s) | Milton Friedman (1912–2006) | Capitalism and Freedom (1962) A Monetary History of the United States (1963) |
Monetarism; “inflation is always and everywhere a monetary phenomenon.” |
| Golden age | George Stigler (1911–1991) | Theory of economic regulation | “Capture theory”: regulations benefit the regulated. |
| Golden age | Gary Becker (1930–2014) | Human Capital (1964) A Treatise on the Family (1981) |
Extension of economics to all human domains (crime, discrimination, family). |
| Golden age | Ronald Coase (1910–2013) | “The Problem of Social Cost” (1960) | Coase Theorem: property rights resolve externalities without state intervention. |
| Second generation (1970s–2000s) | Robert Lucas (1937–2023) | Lucas critique (1976) | Rational expectations: economic policy is ineffective if people anticipate it. |
| Second generation | Eugene Fama (1939–) | Efficient market hypothesis | Prices reflect all available information. |
| Current | Richard Posner, Steven Levitt (Freakonomics), John Cochrane | — | Economic analysis of law and radical empirical applications. |
2. Main concepts
- Monetarism: The quantity of money is the key determinant of inflation and of the business cycle. The Federal Reserve should follow a fixed rule of monetary growth (Friedman initially proposed 3–5% per year). Total rejection of fiscal Keynesianism.
- Positive vs. normative economics (Friedman): Economic science should be descriptive and empirical, not prescriptive. Use data, regressions, and statistical tests (Popperian falsificationist method applied to economics).
- Efficient markets and rational expectations hypothesis: Prices incorporate all information; agents rationally anticipate policies. That is why state intervention is useless or counterproductive.
- Human capital theory (Becker): Education, health, and skills are rational investments by the individual. Extension of microeconomics to sociology and psychology.
- Economic analysis of law and regulation (Coase, Stigler, Posner): Market failures are better resolved with clear property rights than with state regulation. Regulations tend to be captured by private interests.
- Pragmatic laissez-faire: Less State than the Keynesian neoclassicals, but not as radical as the Austrians. They accept a central bank, a negative income tax (Friedman), and some minimal interventions.
3. Underlying philosophical vision
- The Chicago School is empiricist, positivist, and utilitarian. It believes in economic science as an almost experimental discipline (data + econometrics).
- The human being is a rational maximizing homo economicus with rational expectations.
- Economic liberty is instrumental (it generates prosperity), not an absolute moral value as in the Austrian School.
- It rejects historicism and Keynesian interventionism, but accepts the mathematical neoclassical framework and the empirical method.
4. Main critiques (Austrian approach and others)
Austrian critiques (Mises, Hayek, Rothbard, Huerta de Soto):
- Empirical positivism: Economics is not a laboratory science. Historical data are never “pure” (the ceteris paribus problem). Austrian praxeology is deductive and a priori; Chicago is inductive and falsifiable, which makes it vulnerable to “junk econometrics” (Mises called it “pseudo-science”).
- Central bank and monetarism: Friedman accepted the state monopoly of money and only asked for fixed rules. The Austrians (Hayek, Mises) demand 100% bank reserves and monetary competition (or a gold standard). Friedman’s monetary rule does not prevent bubbles (as seen in 2008).
- Rational expectations and efficient markets: They ignore dispersed and tacit knowledge (Hayek) and the role of the Kirznerian entrepreneur who discovers opportunities under real uncertainty, not in probabilistic models.
- Pragmatic utilitarianism: It defends the market by results (efficiency), not by ethical principles of private property and non-aggression (Rothbard). That is why Friedman supported the negative income tax and voucherized public education—things Austrians reject as interventionism.
- Excessive mathematical method: Though less abstract than Walras, it remains within neoclassical static equilibrium.
Austrian response: Chicago was a tactical ally against Keynesianism (Friedman and Hayek were friends and shared the 1974 Nobel), but it represents a lukewarm and statistical libertarianism. Its political success (Reagan, Thatcher) came precisely from Austrian ideas that Friedman popularized, but he diluted their radicalism.
What is Monetarism?
- Simple definition: Economic theory developed mainly by Milton Friedman and Anna Schwartz (especially in their book A Monetary History of the United States, 1963) which holds that inflation and economic fluctuations are, ultimately, monetary phenomena.
- Central ideas:
- “Inflation is always and everywhere a monetary phenomenon” (Friedman’s famous phrase).
- The quantity of money in circulation (money supply) determines the general price level in the long run.
- It proposes a fixed monetary rule: the money supply should grow at a constant and predictable rate (for example, 3–5% per year, equal to the real growth of the economy), rather than letting the central bank act discretionarily.
- It rejects Keynesian fiscal policy (public deficits to stimulate) and prioritizes control of the quantity of money.
- Historical success: In the 1970s–80s it explained stagflation (inflation + unemployment) that Keynesianism could not explain. It influenced the policies of Reagan (USA), Thatcher (United Kingdom), and the creation of independent central banks.
Austrian critique (brief and direct):
The Austrians (Mises, Hayek, Rothbard) agree that inflation is monetary, but disagree radically on the cause and the solution:
- For the Austrians the problem is not only the quantity of money, but its asymmetric injection through bank credit (artificial credit expansion), which distorts the temporal structure of production (Austrian theory of the business cycle).
- A fixed monetary rule (monetarism) is still state intervention and generates cycles; the only coherent solution is free banking (private banks issuing money backed by gold or commodities) or, in Rothbard, 100% reserves.
- Friedman and the Chicago school see the cycle as a problem of “too much or too little” money; the Austrians see it as a problem of bad relative-price signals caused by the central bank.
5. Present-day legacy
It dominated Western economic policy from 1980 until the 2008 crisis. It influenced deregulation, the Washington Consensus, and the independence of central banks. Today it remains strong in finance (efficient markets) and in conservative/libertarian think tanks, but it has lost ground to New Keynesian Economics and behavioral economics. In 2026 it remains the school most taught in “pro-market” economics departments in the USA.
