Love him or hate him, Milton Friedman was a giant of 20th century economics, and this book provides a good example of his thinking on economics when Keynesianism was in the ascendancy. This book is a collection of his early papers (some previously published articles and book reviews, some unpublished before this book) on a variety of topics. There is no common theme other than they are all written by Friedman and all were to have some influence on the economics profession (some more - much more - than others). The most famous paper/chapter in the book is the first, "The Methodology of Positive Economics". Although the book's title proclaims it to be about 'positive' (fact-based analysis) economics, many of the papers are actually about policy and are fairly explicitly normative.
