Note 569 — Chapter XXIV
Reading edition
Kemmerer, in general, is less concerned, apparently, with defending a causal quantity theory than with defending the "equation of exchange." To the extent that this is true, I have little quarrel with his doctrines. To "prove" the "equation of exchange," however, is, first, a work of supererogation, and, second, in no sense a proof of the quantity theory. Vide the chapters, supra, on the equation of exchange and on statistics of the quantity theory.
