Reference excerpt

Price Theory: A Provisional Text is an economics book by Milton Friedman.

Background Milton Friedman had a significant impact on graduate education in economics at the University of Chicago. He played a role in shaping the Chicago tradition in price theory, which began with Frank Knight and Jacob Viner in the 1920s and 1930s. This tradition has been spread globally by numerous students and scholars, including Friedman himself, as well as other notable economists from Chicago such as George Stigler, Gary Becker, and Ronald Coase. Friedman studied mathematics and economics at Rutgers University before pursuing graduate studies at the University of Chicago and later Columbia University. He received his Ph.D. from Columbia in 1946 and held various appointments outside academia during the period from 1935 to 1946. Friedman joined the faculty at the University of Chicago in 1946, where he taught price theory classes. Despite being known for his work in macroeconomics and monetarism, Friedman's teaching helped solidify the Chicago tradition in price theory. Price theory was a significant aspect of his legacy as a teacher, and he taught the subject from 1946 to 1964 and again from 1972 to 1976. Notable economists who took Friedman's price theory course include James M. Buchanan, Gary Becker, and Robert Lucas Jr., all of whom later became Nobel laureates.

Summary Friedman's book Price Theory: A Provisional Text, originally based on lecture notes taken by David I. Fand and Warren J. Gustus in 1951–52. These notes were popular among graduate students and eventually prompted Friedman to work on their publication. The revised edition was prepared when Friedman resumed teaching price theory in the early 1970s. Friedman's approach to price theory emphasized the insights of Alfred Marshall, combining theoretical analysis with real-world applications. This approach, characterized by its simplicity compared to more mathematically complex theories, offered a powerful tool for addressing a wide range of economic problems. Economists such as Robert Lucas and Gary Becker praised Friedman's approach for its broad applicability and impact.

Worked examples

Example 1 — a first encounter with Price Theory (Milton Friedman)

Start with the simplest possible case. Write down what Price Theory (Milton Friedman) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Price Theory (Milton Friedman) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Price Theory (Milton Friedman) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Price Theory (Milton Friedman)

In research: Price Theory (Milton Friedman) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Price Theory (Milton Friedman) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Price Theory (Milton Friedman) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 non-fiction books, Economics books, Works by Milton Friedman, so understanding it makes those chapters shorter.
In everyday life: Look for Price Theory (Milton Friedman) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
