My own explanation of the causal sequence whereby expanding trade brings money into a country would be radically different from that given by Fisher in the first quotation. I should expect, first, that rising _prices_ would encourage rising trade; I should then expect the rising volume of trade, with higher prices, to lead borrowers to need, and secure, larger loans from the banks, with, as loans and deposits rise in proportion to reserves, some slight increase in "money-rates," just enough to draw to the country the extra gold which bankers felt desirable to add to their reserves. I should expect the causal sequence to be the exact reverse of that which Fisher indicates. With falling prices, or waning volume of trade--which would usually come together,[320]--I should expect loans to be reduced, deposits to be reduced, money-rates to fall, and gold then to leave the country again. I should expect this sort of thing to happen normally, and not infrequently, and I should expect gold to come in and go out many times in the course of a business cycle. This would seem to be the sort of explanation which our modern theory of _elastic_ bank-credit would give in connection with this problem. I shall not here go into details with the theory of elastic bank-credit. The theory has been too well established in the debates between the "Currency School" and the "Banking School"[321] in regard to bank-notes to need elaboration and defence here, and the essential identity of deposits and elastic bank-notes from this angle is one of the commonplaces of the literature of banking. What I am here concerned with is the highly significant fact that Fisher's "normal" theory finds no place for this highly important phenomenon. The quantity theory has no explanation of elasticity to give. On the basis of the quantity theory, and for all that the quantity theory can say, the Currency School was right! Fisher offers us, virtually, a "currency theory" of deposits. "Suppose, as has actually been the case in recent years, that the ratio of M' to M increases in the United States. If the magnitudes in the equations of exchange in other countries with which the United States is connected by trade are constant, the ultimate effect on M is to make it less than what it would otherwise have been, by increasing the exports of gold from the United States or reducing the imports. In no other way can the price-level of the United States be prevented from rising above that of other nations in which we have assumed this level and the other magnitudes in the equation of exchange to be quiescent." (P. 162.) If "bank-notes" be substituted for "M'", in this quotation, we have here a perfect statement of the position of the "Currency School" in that great debate. Must this old issue be fought all over again? And yet, I defy any consistent quantity theorist to find any flaw in Fisher's argument on this point. There is no place for a theory of elastic bank-credit
