The question as to how long a time is required, in Fisher's view, for a transition to occur, and for his normal tendencies to dominate, is nowhere made clear. The quantity theory, in the hands of some writers, is a very long run theory, for others, it is a short run theory. Thus, Taussig would make the "run" exceedingly long.[190] Mill makes it a short run theory. "It is not, however, with ultimate or average, but with immediate and temporary prices, that we are now concerned. These, as we have seen, may deviate widely from the standard of cost of production. Among other causes of fluctuation, one we have found to be, the quantity of money in circulation. Other things being the same, an increase of the money in circulation raises prices, a diminution lowers them. If more money is thrown into circulation than the quantity which can circulate at a value conformable to its cost of production, the value of money, so long as the excess lasts, will remain below the standard of cost of production, and general prices will be sustained above the natural rate."[191] I pause to note that it is really strange that a single name should describe theories so different, resting on such essentially different logic. Long run or short run theories, all are "quantity theories," whether "money" be defined as gold, or as all manner of media of exchange, or as only those media of exchange which pass from hand to hand without endorsement. Fisher would doubtless call his theory a long run theory. From the standpoint of the notion that "prices ... lag behind their full adjustment and have to be pushed up, so to speak, by increased purchases,"[192] however, we get a short run quantity theory doctrine. The logic of these two is very different. The short run doctrine seeks to explain the actual process of price-making in the market. 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.
Finding it impossible to limit Fisher to any single statement of the quantitative importance of his normal theory as compared with the other tendencies at work, but concluding that, on the whole, he considers it of high importance, I shall now proceed to an analysis of the reasoning by which he seeks to justify it as a qualitative tendency. I shall maintain that, however long or short the period required, however strong or weak the tendency he defends, the reasoning by which he seeks to justify it is unsound, and that even as a qualitative tendency, the quantity theory is invalid. At a later part of the book, as in an earlier part,[194] I shall undertake to find the modicum of truth which the quantity theory contains, and shall show that no quantity theory is needed to exhibit this modicum of truth.
CHAPTER XI
BARTER
In the statement of the quantity theory, the proviso is commonly made that all exchanges must be made by means of money, or of money and bank-credit. Barter is excluded by hypothesis. If resort to barter were possible, then people might avert the fall in prices due to scarcity of money, or increase in trade, by dispensing with money in part of their transactions, and the proportional decrease in prices which the quantity theory calls for would be lacking. Is this assumption true? Is barter banished from the modern world, or does it remain reasonably possible, and, to a considerable degree, actual?
Fisher maintains the thesis—the failure of which he admits would spoil the quantity theory[195]—that barter is practically impossible, and negligible in modern business life. "Practically, however, in the world to-day, even such temporary resort to barter is trifling. The convenience of exchange by money is so much greater than the convenience of barter, that the price adjustment would be made almost at once. If barter needs to be seriously considered as a relief from money stringency, we shall be doing it full justice if we picture it as a safety valve, working against a resistance so great as almost never to come into operation, and then only for brief transition intervals. For all practical purposes and all normal cases, we may assume that money and checks are necessities for modern trade."[196]
This contention seems to me untenable. I think it can easily be shown that barter remains an important factor in modern business life, especially if one extends the term barter, a little, to cover various flexible substitutes for the use of money and checks in effecting exchanges. Clearly from the standpoint of the present issue, such an extension of the meaning of barter is legitimate, as any such substitutes would equally spoil the proportionality in the supposed relation between prices and money, or prices and trade.
Where does one find barter? Well, not to be ignored would be the advertisements which fill many columns of such a paper as the New York Telegram in the course of a week; "Wanted: to trade a well-trained parrot for a violin"—a trade that might, or might not, be a wise one! There is a good deal of such simple barter among the people. Then, perhaps more important, is the regular practice of sewing machine, piano, automobile, and other similar companies of taking part of the payment for a new machine, piano,[197] or automobile in the similar thing which the owner is discarding. The old machine, piano, etc., are then repaired, repainted, and sold again. This is a very extensive practice. Again, there are companies which combine the business of wrecking old houses and building new ones, who regularly take the old materials as part of their pay. This is a highly important feature of the organized building trade in great cities, and is frequently done in small towns. The building trade is no negligible matter. The "horse-trade" still thrives in rural regions, and barter of various kinds, of live stock, of grain and hay, of fresh and cured meat, and of labor, is an important feature in rural life in many sections. Much of agricultural rent in the South is still paid in kind, under the "share system." Much labor, especially farm and domestic labor, is still paid for partly in kind. Where payments for labor are made in orders on company stores, we have again what is virtually barter, from the standpoint of the point at issue. Real estate transactions make large use of barter. Farms are exchanged for one another, with some cash (or more usually, a promissory note) "to boot." The writer has repeatedly heard real estate men say to customers: "I can't sell it for you very easily, but I can trade it off, and maybe you can sell what you trade it for." This is perhaps more frequent in rural real estate transactions, and in the smaller cities, than in large cities, but it is very extensive in New York City.[198]
