Money is offered against goods, and the actual quantities on each side determine the momentary price-level, concretely. Or, when credit is considered, money and credit offered against goods, at a given time, or in a given short period, determine the actual price-level reached. This is the logic of the equation of exchange--actual money paid is necessarily equal to actual money received. The long run doctrine is fundamentally based on a different notion. Surrendering the actual or average of price-levels to other causes, in part, it still asserts that, given time enough, and barring new disturbing tendencies, a price-level will ultimately be reached which will bear it out. I find no recognition, on Fisher's part, of the fact that these two doctrines are different, and, in fact, I find them blended and confused in the course of his argument. He would doubtless maintain that his is a long run doctrine. But how long is the "run"? Sometimes it seems to be, as already shown, a whole business cycle. Sometimes a passing season, as the fall. When he undertakes to apply his theory to a practical proposal for regulating the value of money, he relies on the quantity theory tendency to bring about adjustments so quickly that it is worth while to make _monthly_ adjustments in anticipation of it.[193] When discussing the changes in gold premium on the Greenbacks during the exciting times of the Civil War, he relies so thoroughly on his theory that he will not allow even the rapid change of four per cent in a single day following Chickamauga to occur except in conformity with the quantity theory. This last statement is so remarkable that I must quote Fisher himself: "It would be a grave mistake to reason, because the losses at Chickamauga caused greenbacks to fall 4% in a single day, that their value had no relation to their volume. This fall indicated a slight acceleration in the velocity of circulation, and a slight retardation in the volume of trade" (263). It would be indeed remarkable if the changes in the gold market, which got war news before the newspapers got it, and where changes in gold premium occurred before the rest of the country could possibly react to the war news, should be controlled by V and T! I had not supposed that the most rigorous of short run quantity theorists would make any such demands on his theory as that. Indeed, I had not supposed that the quantity theory would feel called on to explain the gold premium, as such, except in so far as the gold premium is an index of general prices.
