Caleb Fuller, an economist who teaches at Grove City College, thinks that many people have a mistaken conception of economics. It is, they think, a dull and dry subject, the “dismal science,” of primary interest to specialists. Fuller disagrees. He says that “economics changed my life” (p. 11; all page references are to the Amazon Kindle edition), and in this wonderful short book, which can be read in an hour or so, he conveys his infectious enthusiasm for it.
What is the reason for his enthusiasm? Fuller says that he can provide readers with “a pair of eyeglasses that can extend our vision beyond where we’re accustomed to looking” (p. 12), and this is the “opportunity cost lens.” (One wonders how a pair of eyeglasses can be at the same time a lens, but this is a quibble.) By using this lens properly, readers will be able to unmask six common fallacies that exercise a malign influence on current thought. In carrying out his project, he follows Frédéric Bastiat and Henry Hazlitt, and he is a worthy successor of them, whom he calls “economics’ greatest communicators” (p. 12).
Before closing with a little price theory puzzle:
No Free Lunch is an ideal book for introductory economics classes and for anyone who wants to understand how the free market works. It would be a good test to see if you understand the book to explain why the lesson summarized in the book’s title is consistent with the fact that the book is, at least as of this writing, available on Amazon Kindle for free.
P.S. David, I’ll work on my grasp of “pair” and “lens.”
