Note 41 — Chapter II

“Money may continually vary in value and yet be as good a measure of value as if it remained perfectly stationary. Suppose, for instance, it is reduced in value.... Before the reduction, a guinea would purchase three bushels of wheat or 6 days’ labour; subsequently it would purchase only 2 bushels of wheat, or 4 days ‘labour. In both cases, the relations of wheat and labour to money being given, their mutual relations can be inferred; in other words, we can ascertain that a bushel of wheat is worth 2 days ‘labour. This, which is all that measuring value implies, is as readily done after the reduction as before. The excellence of a thing as a measure of value is altogether independent of its own variableness in value” (p. 11, Bailey, “Money and its Vicissitudes.” London, 1837).
