I have previously written about (here, for example) what I call economism, or excessive belief in the little bit that you remember from Economics 101. The problem is twofold. First, Economics 101 usually paints a highly stylized, unrealistic view of the world in which free markets always produce optimal outcomes. Second, most people in the world who have taken any economics have only taken first-year economics, and so they never learned that, from a practical perspective, just about everything in Economics 101 is wrong. (Complete information? Rational actors? Perfectly competitive markets?) This produces a nation of people like Paul Ryan, who repeats reflexively that free market solutions are always good, journalists who repeat what Paul Ryan says, and ordinary people who nod their heads in agreement.
The problem is not the economics profession per se. These days, to make your mark as an economist, it helps to be arguing (or, better yet, proving) that the free market caricature of Economics 101 is wrong. The problem is the way it is taught to first-year students, which pretty much assumes that Joseph Stiglitz, Daniel Kahnemann, Elinor Ostrom, and many others had never existed.
What we need, I have often thought, is a companion book for students in Economics 101, one that points out the problems with the standard material that is covered in the textbook. For a while I was thinking of writing such a book, but I decided against it for a number of reasons, one of them being that I am not actually an economist. Fortunately, John Komlos, who really is an economist, has written a book along these lines, titled What Every Economics Student Needs to Know and Doesn’t Get in the Usual Principles Text.
