Lanny Ebenstein’s “Milton Friedman” is a chronological view of Friedman’s life and work. Ebenstein’s treatment is balanced and comprehensive, while still remaining accessible to the general reader.
Born the son of Hungarian immigrants, Friedman went on to become a pioneer in mathematics, a contrarian, then a standard-bearer in macroeconomic theory, and finally, a major figure in the American libertarian movement. As an adviser to the Reagan administration, a widely read columnist, and a television star he played an influential role in fostering the rejuvenation of free market thought in the 1980s.
After taking degrees in mathematics and economics at Rutgers, the 20 year old Friedman studied economics at Chicago and Columbia, Hence, he was exposed to the methodological controversies affecting the discipline in depression stricken America.
After a two year stint at Treasury, Friedman joined a group of mathematicians at SRG, where he worked on defense related issues, including the Manhattan Project. At SRG, Friedman along with Wallis and Wald refined sequential analysis as a statistical technique where the sample size is not determined a priori. Data is evaluated as it is collected, and further sampling is stopped in accordance with a pre-determined stopping rule as soon as significant results are observed. Thus it is a more economical method for evaluating data, insofar as a conclusion may be reached much earlier than would be possible with classical analysis.
Following the war, Friedman returned to academia. Ebenstein writes with clarity. He integrates Friedman’s consumption function work to his work on monetary theory; both were a radical departure from the regnant Keynesianism of the period. Moreover, Ebenstein links this empirical work to Friedman’s influential statement on methodology: “The Methodology of Positive Economics.”
As the 1960s dawned, Friedman became a public intellectual and an apostle of freedom. In “Freedom and Capitalism” he demonstrated the inextricable nexus between economic and political freedom. His “Free to choose” became a worldwide phenomenon, and in 1976, he was awarded the Nobel Prize for Economic Science. Only Hayek had a comparable role in changing the zeitgeist.
Ebenstein’s book is well-researched and succinct. For the most part he avoids faculty lounge gossip, and deals with the controversies the profession faced during Friedman’s lifetime.
