The Essential Milton Friedman
by Steven E. Landsburg

When economists are called “influential,” it usually means they’ve changed the way other economists think. By that standard, Milton Friedman was one of the most influential economists of all time. He revolutionized the way economists think about consumption, about money, about stabilization policy, and about unemployment.

When economists are called “influential,” it usually means they’ve changed the way other economists think. By that standard, Milton Friedman was one of the most influential economists of all time. He revolutionized the way economists think about consumption, about money, about stabilization policy, and about unemployment. He demonstrated the power of committing oneself to a few simple assumptions about human behaviour and then relentlessly pursuing their logical implications. He developed and taught new ways of interpreting data, testing his theories by their ability to explain multiple disparate phenomena. His successes were spectacular and his techniques were widely emulated.

In several cases, Friedman’s methods inspired the creation of entire new subfields including the economic analysis of law, the quantitative approach to economic history, the economics of crime and punishment, the economics of family relationships, and the economic approach to finance—leading to multiple Nobel prizes for Friedman’s acolytes.

But Friedman’s influence extended beyond economists. To the public at large, he was the world’s foremost advocate for economic and personal freedom. Through his writings and his media appearances, he educated millions about how markets work and how governments often fail. He restored the respectability of classical liberal notions that had fallen into disfavour, and he did so not by artful propaganda but by conveying a deep and lasting understanding of the ideas themselves.

And he influenced policymakers. In the United States, he helped to end the military draft, to broaden educational choice, and to change the regulatory climate. Worldwide, almost all central banks now follow policies that are grounded in Friedman’s insights and recommendations (updated, of course, for the changed world we now live in), and have thereby made the world a richer and more stable place, largely delivered from the sort of disastrous policy errors that were once routine. When the Soviet Union collapsed, Friedman’s writings inspired the design of new institutions in several former Communist countries, and those that adopted this course were rewarded with prosperity and freedom.

After an early flirtation with statistics (where he developed the “Friedman Test” to interpret disagreements among judges in, say, a skating competition), Friedman moved on to study economics, writing a 1946 doctoral dissertation on, among other things, the effects of occupational licensing, a subject to which he frequently returned. The next year, he accepted a job at the University of Chicago, where he did most of his groundbreaking academic work on consumption behaviour, monetary theory, and monetary history, and served as the undisputed intellectual leader of the economics department for 30 years. In 1976, he was awarded the Nobel Prize.

The public became acquainted with Friedman through his 1962 bestseller Capitalism and Freedom and his subsequent series of approximately 300 columns in Newsweek Magazine, along with his increasing presence as an advisor to policymakers. After his retirement in 1977, Friedman moved to the Hoover Institution at Stanford University and, in collaboration with his wife Rose and the television producer Robert Chitester, created the television series Free to Choose and an accompanying book by the same title. Both the TV series and the book drew huge audiences and cemented Friedman’s worldwide celebrity. Several Eastern European leaders specifically cited Free to Choose as a major inspiration for their new economic policies after the fall of the Soviet Union.

It would take several large volumes to do justice to Friedman’s extraordinary contributions to economic theory, economic practice, economic policy, and economic literacy. The few brief chapters that follow will give an overview of what those volumes might contain.

  • The Permanent Income Hypothesis
    Chapter 1

    The Permanent Income Hypothesis

    Suppose you believe your economy is in the doldrums because people are somehow not spending enough. How do you get them to open up their pocketbooks?

    Start by perusing some data. You’ll quickly discover that spending is highly correlated with income. It’s well documented that if, in any given year, Alice out-earns Bob by a dollar, then on average she’ll outspend him by at least 90 cents.

  • Money, Prices, and Inflation
    Chapter 2

    Money, Prices, and Inflation

    The Nobel Prize-winning economist Robert Solow once observed that “Everything reminds Milton of the money supply.” It’s certainly true that Milton Friedman had a lifelong fascination with the money supply, leading to insights that profoundly changed both academic thought and practical policymaking.

    Actually, Friedman’s analysis begins on the other side of the market—the demand for money—as opposed to the supply. To the casual reader, the idea of studying the “demand for money” might sound absurd. Don’t we all want as much money as we can possibly get? Isn’t that all there is to say on the matter?

  • Monetary Policy
    Chapter 3

    Monetary Policy

    Now that we’ve talked about how the price level is determined, let’s double back and ask why we should care about the price level in the first place. If the money supply doubles, and all prices (including wages) double in response, has anything important really changed?

    Probably not. Instead of costing $5, a hamburger now costs $10. Alice has to work just as many hours to earn that $10 hamburger today as she worked to earn a $5 hamburger yesterday. Instead of carrying $25 in her pocket (enough to buy five hamburgers), she’ll carry $50—still enough to buy five hamburgers. Instead of keeping $1,000 in her chequing account, she’ll keep $2,000—the same fraction of her income that she’s always kept.

  • Monetary History
    Chapter 4

    Monetary History

    The quantity theory of money—that is, the circle of ideas surrounding the notion that prices tend to move in tandem with the money supply—has a long history going back to the astronomer Nicolaus Copernicus in the fifteenth century. After the onset of the Great Depression in the early 1930s, the new generation of “Keynesian” economists largely rejected the quantity theory, arguing that often, people don’t have strong stable preferences about how much money they hold. Therefore, said the Keynesians, when the authorities inject new money into the system, people might simply hold it, without bidding up prices.

  • Unemployment
    Chapter 5

    Unemployment

    In 1958, the economist William Phillips noticed a striking correlation: Times of high inflation are times of low unemployment, and vice versa. Over the next decade, the correlation held strong.

    The lesson most economists drew was that policymakers face a trade-off: You can have less unemployment, provided you’re willing to tolerate (and even engineer) a bit more inflation.

    Milton Friedman, almost a lone voice in the wilderness, begged to differ. Not for the first time in his career, it fell to Friedman to remind the world that correlation is not the same as causation.

  • Chicago Price Theory
    Chapter 6

    Chicago Price Theory

    From his arrival at the University of Chicago in 1946 until his retirement in 1977, Milton Friedman did more than anyone to set the intellectual agenda of the Chicago economics department. Though Friedman was primarily known as a monetary economist, the subject he chose to teach was price theory, or microeconomics. Microeconomics was a required first-year graduate-level course and it shaped the thinking of generations of students, giving them an extraordinarily rich set of tools for analyzing problems in all areas of economics.

  • Capitalism and Freedom
    Chapter 7

    Capitalism and Freedom

    In 1962, Milton Friedman burst forth from the academy into the public square with Capitalism and Freedom, subsequently ranked number 16 on Time Magazine’s list of the most influential books written in English in the years 1923–2011.25 More than half a century later, it remains in print in over a dozen languages and ranks near the very top of Amazon’s list of bestsellers in economic theory.

  • Policy Analysis
    Chapter 8

    Policy Analysis

    Having drawn the connection between free markets and free people, Friedman moved on to specifics. The later chapters of Capitalism and Freedom make the case for limiting the role of government in education, labour markets, corporate governance, housing, old age insurance, the alleviation of poverty, and more.

  • Activism
    Chapter 9

    Activism

    After the success of Capitalism and Freedom, Milton Friedman became the world’s most widely recognized advocate for economic freedom. His op-ed columns in Newsweek, appearing every three weeks for 18 years, reached a direct audience of about three million subscribers and were widely quoted in other media. Soon his face and his voice were familiar to many millions more, through his frequent congressional testimony, public speeches, and media appearances.

  • Civil Discourse
    Chapter 10

    Civil Discourse

    In 1980, Milton and Rose Friedman collaborated with the visionary television producer Bob Chitester to create a television series called Free to Choose. The series aired originally on the Public Broadcasting System in the United States, where, with about three million viewers per episode, it was one of the most popular programs in PBS history. A companion volume with the same title, written by the Friedmans, was near the top of the year’s bestseller lists.
