Rothbard’s Refutation of the Quantity Theory of Money
In chapter 11 of Man, Economy, and State [1962] (2009), Rothbard sets out his theory of money and its influences on business fluctuations. Among the many insights Rothbard provides, we find a compelling and cogent refutation of Irving Fisher’s equation of exchange (in section 13)—which underlies the monetarist quantity theory of money.
