tion arises, Do these various substitutes operate on prices in the same manner as money itself? Does an increase in the quantity of transferable paper tend to raise prices, in the same manner and degree as an increase in the quantity of money? There has been no small amount of discussion on this point among writers on currency, without any result so conclusive as to have yet obtained general assent.
I apprehend that bank notes, bills, or cheques, as such, do not act on prices at all. What does act on prices is Credit, in whatever shape given, and whether it gives rise to any transferable instruments capable of passing into circulation, or not.
I proceed to explain and substantiate this opinion.
§ 2.Money acts upon prices in no other way than by being tendered in exchange for commodities. The demand which influences the prices of commodities consists of the money offered for them. But the money offered, is not the same thing with the money possessed. It is sometimes less, sometimes very much more. In the long run indeed, the money which people lay out will be neither more nor less than the money which they have to lay out: but this is far from being the case at any given time. Sometimes they keep money by them for fear of an emergency, or in expectation of a more advantageous opportunity for expending it. In that case the money is said not to be in circulation: in plainer language, it is not offered, nor about to be offered, for commodities. Money not in circulation has no effect on prices. The converse, however, is a much commoner case; people make purchases with money not in their possession. An article, for instance, which is paid for by a cheque on a banker, is bought with money which not only is not in the payer's possession, but generally not even in the banker's, having been lent by him (all but the usual reserve) to other persons. We just now made the imaginary supposition that all persons dealt with a bank, and all with the same bank,
