“The sums of money collected in hoards lie there idle, waiting for the moment when commerce needs them for maintaining the stability of the objective exchange-value of money; and all those sums of money, that might threaten this stability when the demand for money decreases, flow back out of circulation into these hoards to slumber quietly until they are called forth again. This tacitly assumes ll the fundamental correctness of the arguments of the Quantity Theory, but asserts that there is nevertheless a principle inherent in the economic system that always prevents the working out of the processes that the Quantity Theory describes.In the first place, it must be recognized that from the economic point of view there is no such thing as money lying idle. All money, whether in reserves or literally in circulation (i.e. in process of changing hands at the very moment under consideration), is devoted in exactly the same way to the performance of a monetary function. The stock of money of the community is the sum of the stocks of individuals; there is no such thing as errant money.”
