I find it amazing now that my first economics class, taught by Alan Sweezy, used John Maynard Keynes’s General Theory of Income and Employment as the textbook. Although this book is one of the most influential works of the twentieth century, it makes a really lousy textbook. Moreover, since I now regard Keynes’s analysis as seriously flawed, it is surprising that I enjoyed the course so much. As a student, I appreciated the simple way that the Keynesian model explained the workings and failings of the overall economy. Especially appealing were the clever policy remedies, such as increased government spending and tax cuts, that Keynes recommended to combat unemployment. Too bad that I discovered later that the model was theoretically and empirically deficient!
