(b) The prosperity of the farmers in the Central West has enabled many to have bank accounts who fifteen years ago could not carry balances. The writer's information from central Illinois is strongly in this direction.
(c) The third evidence is found in the growth of the number of small banks, especially in the country districts....
(d) The appearance of a considerable proportion of checks in the deposits of mutual savings banks is also, to some degree, significant....
On the other hand, the increase of that part of the population which consists of the wage-earning class, by whom the use of checks is small, is undoubtedly greater than that of our other classes of population. However, the wealthy classes, though fewer in number, have more to spend and their use of checks raises the proportion of credit paper in payments.
We can not expect any social movement to continue steadily in one direction for an indefinite time. Such evidence as inquiries of this character furnish seems to show that there is a certain ebb and flow in the proportion of checks used in business payments. With a given amount of money a certain proportion of it can be used for bank reserves on which to build credit transactions. For a time the volume of business will increase more rapidly than the money supplies, so that the proportion of credit business to the whole will increase, the improvement of the credit machinery in the meantime facilitating the movement. But the perfection of the facilities for utilizing to the utmost a given reserve, or a slowly increasing one, will come to a stop after a time, and it will be necessary to increase the money supply for any further expansion of credit. In the language of business, another unit of capital must be added to plant. The unit added to the social capital devoted to exchange—that is, the additional amount of money—will be larger than is necessary for most profitable immediate use, consequently the proportion of money exchanges will for a time show an increase. We may conclude, therefore, that the volume of business done on credit gradually increases as the population and total amount of business are enlarged, but at a decreasing rate and with occasional or periodic retardations.
2. Relation of credit exchanges to the volume of money and prices.—It is pertinent to inquire, now, what effect, if any, this great settlement of indebtedness by means of credit paper has upon the value of money. Evidently, it can influence this value, or the general price level, only as it changes the amount of demand for money. We have seen reason, now, to think that 80 per cent. of our business transactions are settled by means of credit paper. Credit paper cancellation enables a larger amount of business to be done with the same amount of money and has an effect in determining the value of money by increasing the demand for reserves....
... The use of credit paper in effecting credit exchanges makes possible a far larger volume of business than could otherwise be done, and that this increased volume of business must in some way influence prices seem undeniable....
... We are told by many that there is a vast amount of credit transactions embodied in banking and clearing-house statistics which may be termed "fictitious." That is to say, they are not a part of the necessary work of exchange in a community. For example, the cotton and wheat crops are sold several times over on the exchanges of the country, but not all these purchases and sales are a necessary part of the process of getting the cotton from the planter to the manufacturer. These sales, we are told, are purely speculative and born out of the credit organization, which, it is urged, merely makes the transactions possible.... However,... these exchanges actually exist. All the purchases involved constitute a part of the demand for means of settlement. Therefore they are to be regarded as a proper part of the exchange business of the country, and in some degree they must influence the need for money....
... The demand for money to effect exchanges includes, first, demand for money for direct exchanges; second, demand for reserves for credit exchanges. Some goods exchange by direct barter and still more probably by indirect barter. If these last exchanges just cancelled one another, the credit paper that grows out of them would also cancel, and no balances would remain to be settled with money. Usually, however, they do not cancel, and the balance must be settled with cash; hence a reserve is necessary.... This demand for reserve is certainly one of the influences that go to determine the value of money. In short, the demand for money includes a demand for direct payment and a demand for reserve....
3. Our monetary circulation.—Our per capita circulation, as estimated by the Comptroller of the Currency, has increased from $21.10 in 1906 to $34.72 in 1908.[42] This is larger than the per capita circulation of other great industrial and commercial countries with the exception of France. Why is it necessary and where is it? It is necessary, perhaps, for the following reasons:
