Milton Friedman, 1912: Harbinger of the Public Choice Revolution



Introduction
Throughout the first fifteen years following the end of World War Two the economics profession throughout the Western World was characterized by a touching belief in the omniscience and impartiality of government as the servant of the public good and by a cynical belief in the endemic failure of free markets to maximize social welfare as defined by the Pareto Principle supplemented by the Kaldor-Hicks-Scitovsky potential compensation test. It was also characterized by the hegemony of Keynesian economics with its support for large and fiscally interventionist governments and its contempt for monetary instruments of macro-economic intervention.

The behemoths who bestrode the economics profession throughout that period were Paul Samuelson, Kenneth Arrow, John Kenneth Galbraith, James Tobin, Robert Solow and Joan Robinson. Classical political economy was dead, buried by the Great Depression and by the writings of John Maynard Keynes (1936). Free market economics was on the ropes, with few advocates and even those forced into perpetual defense in an environment in which public choice analysis played no role. The future for economic liberty and capitalism was bleak indeed.

In a world in which free markets were systematically derided, there would be no effective role for the emergence of public choice to analyse political market failure and to even the playing field between the competing advocates of government and of free markets. First, it would be necessary for some brave soul to step forward and to clear the brush from the forest by re-formulating the case both for capitalism and for monetary policy as the fundamental basis for individual freedom. Then and only then would it be possible for the public choice revolution to begin. Such a soul was Milton Friedman, arguably the most influential economist of the twentieth century, one of that century’s greatest economic advocates of liberty, and certainly a necessary pre-condition for and harbinger of the public choice revolution.
The Early Years
Milton Friedman was born on July 31, 1912 in Brooklyn, New York City, the only son and the youngest of four children. His father, Jeno Saul Friedman (1878) and his mother, Sarah Ethel Landau (1881) were both born in the small, mostly Jewish town of Beregszasz in Carpetho-Ruthenia. Carpetho-Ruthenia was then in the Hungarian part of Austro-Hungary. After World War I, it became part of Czechoslovakia; after World War II, it became part of the USSR; after the demise of the USSR it became part of Ukraine. The town is now called Berehovo.

At the age of sixteen (1894) Friedman’s father migrated to the United States and settled in Brooklyn. His mother migrated to the United States when she was fourteen (1895). Shortly after her arrival, Friedman’s mother went to work as a seamstress in a sweatshop, a welcome opportunity for her to earn a living while she learned English and adjusted to the new country. Shortly after his arrival, Friedman’s father went into business on his own, first as a sweatshop owner, later as the owner of a retail dry goods store and an ice-cream parlor. He remained self-employed for the remainder of his life (Friedman and Friedman 1998, 20).

In these respects, both of Friedman’s parents benefited from late nineteenth century capitalism as it was practiced in the United States. Their family income was always small and uncertain and they sometimes resorted to post-dated checks. For the most part, however, the family struggled to balance its budget while investing to the best of its ability in the education of its young (Friedman and Friedman 1998, 21).

In 1913, little more than a year after Milton Friedman’s birth, the Friedman family moved from Brooklyn to Rahway, a small town in New Jersey that served mostly as a bedroom city for commuters to New York and Newark. For most of Friedman’s youth, his mother ran the store while his father commuted to New York where he worked as a jobber or petty trader. The common language within the household was English, since this was deemed to be essential for the family to function economically in the New World. Milton Friedman never became proficient in Hungarian, but he picked up enough Yiddish to understand the conversation of adults (Friedman and Friedman 1988, 21).

Until shortly before his bar mitzvah at the age of thirteen, Milton Friedman was fanatically religious, attending Hebrew School at the local synagogue and conforming in every detail to the complex dietary and other requirements of Orthodox Judaism. By the age of twelve, however, he decided that there was no valid basis for his religious beliefs and he shifted to complete agnosticism, becoming fanatically anti-religious, although he did go through the bar mitzvah ceremony for the sake of his parents.

Friedman’s father suffered for many years from angina and died from a heart attack at the age of forty-nine when his son was only fifteen years of age and was preparing to enter his senior year in high school. Milton Friedman inherited this genetic defect and would have died himself in his sixties had he not benefited from the perfection of by-pass surgery techniques. Friedman’s mother and sisters worked to support the family while Milton, as the male sibling, was encouraged to complete his education.

From 1924 to 1928, Friedman attended Rahway High School, graduating with a good grounding in languages, mathematics and history. He ascribes his enduring love of mathematics to a civics teacher who put the classic proof of the Pythagorean theorem on the blackboard while quoting from the poet Keats’ Ode on a Grecian Urn: “Beauty is truth, truth beauty - that is all ye know on earth, and all ye need to know” (Friedman and Friedman 1998, 24). Although the Friedman household could afford few books, the young Friedman became a voracious reader, almost exhausting the contents of the small local public library.

Encouraged by two of his high school teachers who were recent graduates of Rutgers University and by his success in competing for a partial scholarship at this then small New Brunswick college, Friedman entered Rutgers University in 1928 as a residential scholar. He worked his way through college as a part-time clerk in the men’s department of a local department store, and he earned his lunch by waiting tables at a restaurant across the street from his dormitory (no doubt this embedded in the young Friedman, through an experience that was not available to his more pampered peers, an understanding that there is indeed no such thing as a free lunch).

Together with a fellow Jewish student, Friedman also engaged in a profitable entrepreneurial venture, buying and selling second-hand undergraduate books within the campus community, in so doing, bringing upon himself the wrath of the university bookstore, whose margins he undercut. During the summer vacations, Friedman covered his living expenses by selling fireworks for the Fourth of July Celebration, and by setting up a summer school for failing high school students, teaching classes in a number of subjects at fifty cents per hour. From an early age, Friedman showed an interest in buying and selling for profit and a predilection for entrepreneurial activity, having learned from his parents to embrace the capitalist market economy.

Friedman’s original intention when entering Rutgers University was to major in mathematics with the objective of becoming an actuary. Although his actuarial results were extraordinarily good for an undergraduate, Friedman soon discovered that actuarial work was not the only paying occupation that used mathematics. Fortunately, he discovered economics and ended his degree program with the equivalent of a double major in economics and mathematics.

This decision changed his life, primarily because of his exposure to two remarkable men, Arthur F. Burns, who later would become Chairman of the Federal Reserve System and Homer Jones who later would become Vice-President of Research at the St. Louis Federal Reserve Bank. Burns inspired in Friedman a passion for scientific integrity, for scrupulous accuracy in the checking of sources and for openness to criticism. Jones provided Friedman with a sound grounding in insurance and statistics, while first introducing him to the Chicago School’s pre-occupation with individual freedom.

In 1932, at the age of nineteen, Friedman graduated from Rutgers University with a degree in mathematics and economics. With the United States in the depths of economic depression and job opportunities very few, he applied for scholarships to a number of universities and received two offers of tuition scholarships, one from Brown University in applied mathematics and the other from the University of Chicago in economics. Had Homer Jones not taught at Rutgers University thus exposing Friedman to the excitement of Chicago economics, Friedman would never have applied to Chicago, or even if he had applied there he would not have received the scholarship that made it possible for him to attend. As it was, he left Rahway for Chicago in the fall of 1932, journeying west of the Delaware River for the very first time.

Studying economics at the University of Chicago was an eye-opening experience for the young Friedman. In 1932, as for the rest of the twentieth century, the Economics Department had the deserved reputation of being one of the best in the United States. Jacob Viner and Frank Knight were the acknowledged stars of the faculty. Henry Schultz, Paul Douglas, Henry Simons (who would move to the law school in 1939), Lloyd Mints, Harry A. Millis and John Nef constituted a talented supporting cast. Debate over economic issues was fierce, the intellectual atmosphere was open and the search for truth dominated scholarly discourse. Friedman was exposed for the first time in his life to a brilliant group of graduate students drawn to this vibrant intellectual atmosphere from all over the world. (Friedman and Friedman 1998, 35).

In his first quarter at Chicago, Friedman took the course on price and distribution theory taught that year by Jacob Viner. This course revealed to Friedman the logical and coherent nature of economic theory as a set of tools to be judged primarily by its usefulness in understanding and interpreting important economic events. Because the students in that class were seated alphabetically, Friedman was also introduced to Rose Director, his future wife and future co-author of two important books on classical liberalism.

During his year at Chicago, Friedman also took Frank Knight’s class on the history of economic thought. He was greatly impressed by Knight’s unrelenting commitment to the pursuit of truth and by his unfailing suspicion of government intervention, attributes that he himself would unfailingly observe in his own career. He was also exposed to Chicago monetary theory in courses taught by Lloyd Mints that focused on the fundamentals and not on the institutional arrangements. He strengthened his technical expertise with courses drawn from the department of mathematics and with a course in econometrics taught by Henry Schultz. Friedman became acquainted during his years at Chicago with fellow graduate students George J. Stigler and Allen Wallis both of whom would later make important contributions to economics. He received his master’s degree at Chicago in 1933.

At the urging of Henry Schultz, Friedman moved to Columbia University for the second year of his graduate work so that he could study with Harold Hotelling. Hotelling would provide him with the same kind of feeling for mathematical statistics that Viner had imbued in him for economic theory. Wesley C. Mitchell introduced him to the empirical analysis of business cycles and John Maurice Clark introduced him to institutional economics. Fritz Machlup, a fellow student, introduced him to Austrian economics.

If Chicago had provided Friedman with the powerful tools of neoclassical price theory, Columbia gave him the institutional framework and the facts relevant for testing those tools (Breit and Ransom 1998, 227). Having satisfied the course requirements for a Ph.D., Friedman returned to Chicago for the academic year 1934-35 as research assistant to Henry Schultz working with him on his path-breaking magnum opus on demand analysis. By the year’s end, Friedman had also satisfied the course requirements for a Ph.D. at Chicago.

There were few academic jobs available in the United States at this stage of the Great Depression and Friedman’s prospects were further lowered by the existence of anti-Semitism within the U.S. academy. Therefore, Friedman left Chicago in the fall of 1935 to take up a well-paid New Deal position in Washington with the National Resources Committee, where he spent two years designing and working on an extensive empirical study of consumer budgets. The experience that he acquired there working with practical statistics would prove to be invaluable throughout his scientific career. The final report on the results of this study was published in two volumes in 1938 and 1939.

Drawing from his work at the Committee, Friedman published an article on a new statistical technique - the use of ranks to avoid the assumption of normality implicit in the analysis of variance - in the December 1937 issue of the Journal of the American Statistical Association. The work he performed at the Committee also formed the basis of a book published in 1957 as The Theory of the Consumption Function. Friedman claims that this is his most important scientific work (Friedman and Friedman 1998, 66).

In the fall of 1937, Friedman moved to New York to begin what would prove to be a long association with the National Bureau of Economic Research and with his former mentor at Rutgers University, Arthur Burns. Friedman worked at the NBER under the supervision of Simon Kuznets to fill in a major lacuna on data on income and wealth, namely the distribution of income and wealth by size. He edited the first three conference volumes on Studies in Income and Wealth for the NBER.

He also revised and completed a preliminary manuscript that Kuznets had drafted on the incomes of professional practitioners. The final product was a book, Incomes from Independent Practice completed in 1940 but published only in 1945 because of a hostile reception to the authors’ conclusions by the then-powerful American Medical Association. (Friedman and Friedman 1998, 74-76). Friedman and Kuznets determined that approximately one half of the observed excess earnings of physicians over dentists was explained by the success of the American Medical Association in limiting entry into medicine.

In addition to working at the NBER from 1937 to 1940, Friedman was able to secure a part-time teaching appointment at Columbia Extension. This was Friedman’s first experience of formal teaching. In 1938, Friedman married Rose Director, six years after first meeting her in Chicago. They would have a daughter, Janet, born in 1943 and now an attorney, and a son, David, born in 1945 and now a well-known professor of law and economics. Rose would be an active partner in her husband’s professional life, co-authoring with him two extremely influential books on political economy.

Harold Groves, who had become acquainted with Friedman at the Income Conference offered Friedman a visiting professorship at the University of Wisconsin for the year 1940-41. Despite efforts by Groves to make this position permanent, and despite an excellent teaching performance in statistics and economics, Friedman would be denied such a position in part at least because of overt anti-Semitism within the Department of Economics (Breit and Ransom 1998, 227, Friedman and Friedman 1998, 91-104).

From 1941 to 1943, Friedman joined Carl Shoup at the U.S. Treasury as a Principal Economist in the Tax Research Division. During this period, Friedman according to his wife, Rose, made the worst intellectual mistake of his career (Friedman and Friedman 1998, 123). In order to raise taxes for the war effort, he helped to devise a scheme for withholding income tax at the source of the income. This innovation (for which Friedman was not solely responsible) arguably is the most important single cause of the growth of government in the United States during the second half of the twentieth century.

Tax withholding tends to obscure the full burden of federal and state tax liabilities on individual taxpayers and thus provides an illusionary reduction in the cost of government. By developing the idea and advocating its implementation as a policy tool, Friedman showed no instinct for the likely public choice implications and no concern for the adverse impact of such a policy for individual liberty (Rowley 1999, 416).

Friedman soon tired of his work on tax reform and moved to New York in 1943 to join a close friend, Allen Wallis as Associate Director of the Statistical Research Group at Columbia University. There he joined a group of distinguished statisticians, including Abraham Wald, Jacob Wolfowitz and Harold Hotelling in work directly relevant to the war effort. Together with Wallis and Wald, he would develop a method of sequential sampling designed to help the U.S. Navy in its sampling inspection of wartime production of munitions. Sequential analysis became the standard method of quality control inspection.

At the same time, Friedman at last turned to his doctoral dissertation drawing upon his NBER study. He completed the dissertation in 1945 and received his doctorate from Columbia University in 1946, more than ten years after completing his course-work for the degree. Of course, the war was a special circumstance. However, it would now be virtually impossible for an American student to drag out his degree program over such a lengthy period and still be allowed to graduate. It is fortunate for economics that Columbia University was flexible. Without a doctorate, Friedman would have found it all but impossible to enter the postwar American academy.

Although Friedman’s early career appears to have been a patchwork of short-term appointments, it formed the basis for all of his subsequent work. Well-versed in mathematics and statistics, formidably well-trained in economic theory and well-experienced in economic policy-making, he would be uniquely equipped to confront a postwar economics profession obsessed with Keynesian macroeconomics, seduced by socialist dogma and aggressively hostile to classical liberal political economy.

The Allied victory over Japan in August 1945 coincided with the end of the ‘Wilderness Years’ for Milton Friedman, years that had been immensely enjoyable and productive despite the absence of any permanent academic position. With the help of George Stigler, Friedman secured a one-year appointment for the academic year 1945-46 at the University of Minnesota, where he taught courses in statistics and economics. Long before the academic year was over, he would accept a tenured position at Minnesota with the rank of associate professor.

During his year at Minnesota, Friedman co-authored with George Stigler a pamphlet attacking rent control, with the catchy title of Roofs or Ceilings. The National Association of Real Estate Boards circulated 500,000 copies of this pamphlet as part of its campaign against rent controls. Friedman’s first foray into classical liberalism marked him as a rising star among the small group of classical liberal scholars in the United States. It also marked the early signs of a willingness to stand firmly against mainstream economic thinking when such thinking could be shown to run counter to sound economic theory (Friedman and Friedman 1998, 150).

In the spring of 1946, Stigler received an offer from the Department of Economics at the University of Chicago, contingent upon approval by the central administration after a personal interview. President Ernest Colwell vetoed the appointment on the grounds that his work was excessively empirical. Ironically, Friedman was offered the position initially offered to Stigler and the New Chicago School was born with an unrelenting emphasis on empirical analysis that has continued throughout the remainder of the twentieth century.

Friedman returned to the University of Chicago in the fall of 1946 as associate professor of economics, succeeding his mentor Jacob Viner in the teaching of microeconomic theory. In 1948, he was promoted to full professor. In 1951, he became the third recipient of the prestigious John Bates Clark medal. In 1963, he was appointed Paul Snowden Russell Distinguished Service Professor. In 1967, he was elected president of the American Economic Association. In 1976, he was awarded the Nobel Prize in Economic Science. Friedman retired from the University of Chicago in 1977, moving to the Hoover Institution at Stanford University as a senior research fellow.
