Milton Friedman

Milton Friedman was the most consequential economist of the second half of the twentieth century — not because his academic contributions were necessarily greater than those of his contemporaries, but because he combined rigorous scholarship with an extraordinary gift for public persuasion that gave his ideas an influence far beyond the academy. His intellectual project was consistent throughout his career: to demonstrate that free markets allocate resources more efficiently and protect individual liberty more reliably than government intervention, and to show that the money supply — not fiscal policy — is the primary determinant of economic activity. These ideas, once considered eccentric, eventually became orthodoxy, reshaping the economic policies of governments from the United States and Britain to Chile and China.

Education and Early Career

Friedman was born in 1912 in Brooklyn, New York, to Jewish immigrants from what is now Ukraine. He grew up in Rahway, New Jersey, and won a scholarship to Rutgers University, where he studied mathematics before discovering economics. Graduate work at the University of Chicago and Columbia University followed, and he spent the war years working on statistical analysis for the National Resources Committee and the Division of War Research at Columbia.

He joined the University of Chicago’s economics department in 1946 and remained there until his retirement in 1977, building Chicago into the global centre of free-market economics. The “Chicago School” became synonymous with monetarism, deregulation, and scepticism toward government intervention, and Friedman was its most prominent and articulate spokesman.

A Monetary History of the United States

Friedman’s most important scholarly work was A Monetary History of the United States, 1867–1960 (1963), co-authored with Anna Jacobson Schwartz. This massive study traced the relationship between the money supply and economic activity over nearly a century, and its central argument — that the Great Depression was caused not by inherent instabilities in capitalism but by catastrophic errors in monetary policy by the Federal Reserve — overturned the prevailing Keynesian consensus and laid the intellectual foundation for monetarism.

The book’s thesis was straightforward but revolutionary: the Fed’s decision to contract the money supply during 1929–1933, when it should have expanded it, turned a recession into a catastrophe. This was not merely an academic argument; it had profound policy implications, suggesting that economic stability depended on steady, predictable growth in the money supply rather than on the fine-tuning of fiscal policy that Keynesians advocated.

Ben Bernanke, speaking at a conference honouring Friedman’s ninetieth birthday in 2002, famously acknowledged the argument’s power: “Regarding the Great Depression: You’re right. We did it. We’re very sorry. But thanks to you, we won’t do it again.” When the 2008 financial crisis struck, the Federal Reserve’s aggressive monetary expansion was directly influenced by Friedman and Schwartz’s analysis.

Capitalism and Freedom

While A Monetary History was Friedman’s most important academic work, Capitalism and Freedom (1962) was his most influential book. Based on lectures delivered at Wabash College in 1956, the book made a systematic case for free-market policies across a wide range of issues: floating exchange rates, a volunteer military, school vouchers, a negative income tax, the abolition of occupational licensing, and the elimination of various forms of government regulation.

The book’s central thesis — that economic freedom is both a necessary condition for political freedom and a value in its own right — was stated with a clarity and force that made it accessible to general readers while remaining intellectually serious. Many of the policies Friedman advocated in 1962, which seemed radical at the time, have since been partially or fully implemented: the United States ended the draft in 1973, adopted floating exchange rates in 1971, and has experimented with various forms of school choice and earned income tax credits.

Free to Choose

Free to Choose (1980), co-authored with his wife Rose Friedman, extended the arguments of Capitalism and Freedom for a broader audience. Based on a ten-part PBS television series of the same name, the book became an international bestseller and was translated into more than a dozen languages. It appeared at exactly the right historical moment: Margaret Thatcher had just become Prime Minister of Britain, Ronald Reagan was about to be elected president, and the stagflation of the 1970s had discredited the Keynesian consensus. Free to Choose provided the intellectual framework for the market-oriented policy revolution that followed.

Controversies and Criticisms

Friedman’s influence was not without controversy. His relationship with Chile’s Pinochet regime — he visited Chile in 1975 and delivered lectures advocating free-market reforms, and several of his former students (the “Chicago Boys”) implemented economic policies under the dictatorship — became a lightning rod for criticism. Friedman defended himself by arguing that he had advocated the same policies to governments of all political complexions, including communist China, and that economic liberalisation would ultimately promote political liberalisation. His critics regarded this as naive at best and complicit at worst.

His monetarist prescriptions have also come under sustained criticism. The Federal Reserve’s attempt to target the money supply directly during the early 1980s, following Friedman’s recommendations, proved difficult in practice because of the instability of the relationship between monetary aggregates and economic activity. Most central banks have since moved to inflation-targeting frameworks that owe more to Keynesian synthesis than to pure monetarism.

More broadly, the era of deregulation and market liberalisation that Friedman championed has been blamed by critics — including economists like Joseph Stiglitz and Paul Krugman — for rising inequality, financial instability, and the erosion of public services. The 2008 financial crisis, in particular, prompted a reconsideration of the free-market consensus that Friedman had done so much to establish.

Is Friedman still relevant in the twenty-first century?

Friedman’s influence remains pervasive, though contested. His monetary economics have been incorporated into mainstream macroeconomics, even as pure monetarism has been superseded. His advocacy for school vouchers continues to shape education policy debates. His argument that corporate social responsibility is a distraction from the proper purpose of business — maximising shareholder value — has been enormously influential in corporate governance, though it is now being challenged by advocates of stakeholder capitalism. His public-intellectual style — combining rigorous analysis with accessible prose and a gift for the devastating example — set the template for economist-commentators who followed.

Collecting Friedman

First editions of Capitalism and Freedom (University of Chicago Press, 1962) are the primary collecting target, with fine copies in dust jacket commanding substantial prices. The book was modestly produced and dust jackets were easily damaged, making near-fine copies scarce. Free to Choose (Harcourt Brace Jovanovich, 1980) was printed in large quantities and is readily available, but signed copies are sought after. A Monetary History of the United States (Princeton University Press/NBER, 1963) is collected more by academic economists than general collectors but is an important title in the history of economic thought.
