PHIL103: Moral and Political Philosophy

Early years

In 1940, Friedman accepted a position at the University of Wisconsin–Madison, but left because of differences with faculty regarding United States involvement in World War II. Friedman believed the United States should enter the war. In 1943, Friedman joined the Division of War Research at Columbia University (headed by W. Allen Wallis and Harold Hotelling), where he spent the rest of World War II working as a mathematical statistician, focusing on problems of weapons design, military tactics, and metallurgical experiments.

In 1945, Friedman submitted Incomes from Independent Professional Practice (co-authored with Kuznets and completed during 1940) to Columbia as his doctoral dissertation. The university awarded him a PhD in 1946. Friedman spent the 1945–1946 academic year teaching at the University of Minnesota (where his friend George Stigler was employed). On February 12, 1945, his son, David D. Friedman was born.

In 1946, Friedman accepted an offer to teach economic theory at the University of Chicago (a position opened by departure of his former professor Jacob Viner to Princeton University). Friedman would work for the University of Chicago for the next 30 years. There he contributed to the establishment of an intellectual community that produced a number of Nobel Prize winners, known collectively as the Chicago school of economics.

At that time, Arthur F. Burns, who was then the head of the National Bureau of Economic Research, asked Friedman to rejoin the Bureau's staff. He accepted the invitation, and assumed responsibility for the Bureau's inquiry into the role of money in the business cycle. As a result, he initiated the "Workshop in Money and Banking" (the "Chicago Workshop"), which promoted a revival of monetary studies. During the latter half of the 1940s, Friedman began a collaboration with Anna Schwartz, an economic historian at the Bureau, that would ultimately result in the 1963 publication of a book co-authored by Friedman and Schwartz, A Monetary History of the United States, 1867–1960.

Friedman spent the 1954–1955 academic year as a Fulbright Visiting Fellow at Gonville and Caius College, Cambridge. At the time, the Cambridge economics faculty was divided into a Keynesian majority (including Joan Robinson and Richard Kahn) and an anti-Keynesian minority (headed by Dennis Robertson). Friedman speculated that he was invited to the fellowship, because his views were unacceptable to both of the Cambridge factions. Later his weekly columns for Newsweek magazine (1966–84) were well read and increasingly influential among political and business people, and helped earn the magazine a Gerald Loeb Special Award in 1968. From 1968 to 1978, he and Paul Samuelson participated in the Economics Cassette Series, a biweekly subscription series where the economist would discuss the days' issues for about a half-hour at a time.

A Theory of the Consumption Function

One of Milton Friedman's most popular works, A Theory of the Consumption Function, challenged traditional Keynesian viewpoints about the household. This work was originally published in 1957 by Princeton University Press, and it reanalysed the relationship displayed "between aggregate consumption or aggregate savings and aggregate income". Keynes believed that people would modify their household consumption expenditures to relate to their existing income levels. Friedman's research introduced the term "permanent income" to the world, which was the average of a household's expected income over several years, and he also developed the permanent income hypothesis. Milton Friedman's research changed how economists interpreted the consumption function, and his work pushed the idea that current income was not the only factor that affected people's adjustment household consumption expenditures. Instead, expected income levels also affected how households would change their consumption expenditures. Friedman's contributions strongly influenced research on consumer behavior, and he further defined how to predict consumption smoothing, which contradicts Keynes' marginal propensity to consume. Although this work presented many controversial points of view that differed from existing viewpoints established by Keynes, A Theory of the Consumption Function helped Friedman gain respect in the field of economics.

Capitalism and Freedom

His Capitalism and Freedom, inspired by a series of lectures he gave at Wabash College, brought him national and international attention outside academia. It was published in 1962 by the University of Chicago Press and consists of essays that used non-mathematical economic models to explore issues of public policy. It sold over 400,000 copies in the first eighteen years and more than half a million since 1962. It has been translated into eighteen languages. Friedman talks about the need to move to a classically liberal society, that free markets would help nations and individuals in the long-run and fix the efficiency problems currently faced by the United States and other major countries of the 1950s and 1960s. He goes through the chapters specifying a specific issue in each respective chapter from the role of government and money supply to social welfare programs to a special chapter on occupational licensure. Friedman concludes Capitalism and Freedom with his "classical liberal" (more accurately, libertarian) stance, that government should stay out of matters that do not need and should only involve itself when absolutely necessary for the survival of its people and the country. He recounts how the best of a country's abilities come from its free markets while its failures come from government intervention.
