Incidentally, our ship may also bring in more gold. The bankers, finding their deposits expanding, may feel it well to cable orders for more gold to increase their reserves, especially as they have been subject to somewhat unusual calls for cash for hand to hand circulation--though this last need they might well have been meeting by expanding their note issue.
Is there anything else to be said? Is not the new equilibrium stable? And is not the causal sequence precisely the reverse of that assigned by the quantity theory? _First_. a rise in prices; _second_, an expansion of credit, book-credit, notes and deposits; _third_, money comes in. If anyone is particularly anxious about the equation of exchange in this process, he may add to my expansion of credit an increase in velocities to keep it straight!
I may add that I see nothing in the "transition" I have described to cause trade to be reduced. Rather, I should expect the rising prices to make trade more active--or better, I should expect the rising _values_ of goods, etc., of which rising prices are the symptom, to make trade more active, particularly as there would be an increase in speculation to bring about readjustments, and to "discount" the prosperity. Nor can I find any reason why trade should be reduced below the old level in the new normal equilibrium. It would make no difference, however, if trade were reduced either transitionally or normally, since the point at issue is the possibility of a rise in prices originating from causes outside the equation of exchange, and compelling a readjustment of a permanent character in the other factors of the equation. The quantity theorist is at liberty to make this readjustment in any way he pleases. My point is made if he has to make the readjustment, and if the price-level stays up!
I have put my illustration in an extreme form to throw the whole thing in relief, and to make the demonstration free from a host of complexities. But is not the causal process essentially the same if we substitute, say, the Southern States for our island, and cotton for our staple? So long as the telegraph bringing news of the ruin of cotton production in India and Egypt, with the higher price of cotton, can come in ahead of the money that the quantity theorist might imagine rushing in a race with it on the train to be offered for the cotton, my point is made. In point of fact, there would be a general rise in prices and wages in the South, which, leading to an expansion of credit, would only gradually and in no definite ratio lead to an increase in money drawn from outside. Buyers outside would pay, not with money, but with checks drawn on New York, and Southern bankers would use their discretion as to how much actual cash they would bring in. With the elastic note issue of our Federal Reserve system, I see no reason to anticipate that money would be drawn to the South in an amount proportionate to the increase in prices. Even if it were, the causation would not run from money to prices, and that is the point at issue. If _rising_ prices can cause increasing money, the whole quantity theory is upset, whatever the proportions involved.
