This work provides a systematic statement of the theoretical position of the Chicago school on monetary economics. Milton Friedman restates the quantity theory of money and discusses the significance of its revival after a period of eclipse by the Keynesian view. Four empirical studies by Phillip Cogan, John J. Klein, Eugene M. Lerner, and Richard T. Selden are provided in support of the theory.
The four studies...of inflation during and after the world wars and in the U.S. over the past century...show a striking regularity in economic response to monetary change. They will be of particular interest to monetary theorists, to empirical investigators in this area, and to economic historians and theorists generally.

"I cannot pretend that the present version is the finished treatise that I had in mind (or in youthful dreams) in the earlier years of teaching the course. But it is a much expanded and, I hope, improved version. I have filled in four of the six gaps that I enumerated in the preface to the initial version. The two I have not filled in are industrial organization for reasons given at the end of chapter 6 and the theory of general equilibrium, because there are such good extant expositions of the classical Walrasian general equilibrium approach and I am not competent to present a succinct yet faithful exposition of the more recent general equilibrium developments, particularly in the field of growth models. In addition, I rather suspect that these developments are as yet in a preliminary and unsatisfactory state." – Milton Friedman, from the preface to the revised edition

Free to Choose (1980) is a book and a ten-part television series broadcast on public television by economists Milton and Rose D. Friedman that advocates free market principles.
Free to Choose: A Personal Statement maintains that the free market works best for all members of a society, provides examples of how the free market engenders prosperity, and maintains that it can solve problems where other approaches have failed. Published in January 1980, the 297 page book contains 10 chapters.
Milton Friedman won the Nobel Memorial Prize in Economics in 1976. Contrary to normal practice the book was written after the TV series was produced, although the line "Basis for the acclaimed public television triumph" is written on the front cover, using the program transcripts as reference. The book was on the United States best sellers list for 5 weeks.
PBS telecast the series, beginning in January 1980; the general format was that of Dr. Friedman visiting and narrating a number of success and failure stories in history, which Dr. Friedman attributes to capitalism or the lack thereof (e.g. Hong Kong is commended for its free markets, while India is excoriated for relying on centralized planning especially for its protection of its traditional textile industry). Following the primary show, Dr. Friedman would engage in discussion with a number of selected persons, such as Donald Rumsfeld (then of G.D. Searle & Company).
The series was rebroadcast in 1990 with Linda Chavez moderating the episodes. Arnold Schwarzenegger, Ronald Reagan, Steve Allen and others give personal introductions for each episode in the series. This time, after the documentary part, Friedman sits down with a single opponent to debate the issues raised in the episode.
