Macroeconomics began as the study of large-scale economic pathologies such as prolonged depression, mass unemployment, and persistent inflation. In the early 1980s, rational expectations and new classical economics dominated macroeconomic theory, with the result that such pathologies can hardly be discussed within the vocabulary of the theory. This essay evolved from the authors' profound disagreement with that trend.
On the basis of theoretical considerations and on the evidence of real-world economies, Frank Hahn demonstrates in unequivocal terms that Monetarism offers an implausible solution to the most pervasive economic problems. He confronts the central issue of current economic theory by making the case that the growth of the money supply is not a necessary cause of inflation, as the Monetarists have assumed.
