The more knowing inflationists recognize that any substantial increase in the quantity of money will reduce the purchasing power of each individual monetary unit—in other words, that it will lead to an increase in commodity prices. But this does not disturb them. On the contrary, it is precisely why they want the inflation. Some of them argue that this result will improve the position of poor debtors as compared with rich creditors. Others think it will stimulate exports and discourage imports. Still others think it is an essential measure to cure a depression, to “start industry going again, and to achieve “full employment.”[*]
There are innumerable theories concerning the way in which increased quantities of money (including bank credit) affect prices. On the one hand, as we have just seen, are those who imagine that the quantity of money could be increased by almost any amount without affecting prices. They merely see this increased money as a means of increasing everyone’s “purchasing power,” in the sense of enabling everybody to buy more goods than before. Either they never stop to remind themselves that people collectively cannot buy twice as much goods as before unless twice as much goods are produced, or they imagine that the only thing that holds down an indefinite increase in production is not a shortage of manpower, working hours or productive capacity, but merely a shortage of monetary demand: if people want the goods, they assume, and have the money to pay for them, the goods will almost automatically be produced.
On the other hand is the group—and it has included some eminent economists—that holds a rigid mechanical theory of the effect of the supply of money on commodity prices. All the money in a nation, as these theorists picture the matter, will be offered against all the goods. Therefore the value of the total quantity of money multiplied by its “velocity of circulation” must always be equal to the value of the total quantity of goods bought. Therefore, further (assuming no change in velocity of circulation), the value of the monetary unit must vary exactly and inversely with the amount put into circulation. Double the quantity of money and bank credit and you exactly double the “price level”; triple it, and you exactly triple the price level. Multiply the quantity of money n times, in short, and you must multiply the prices of goods n times.
There is not space here to explain all the fallacies in this plausible picture.[†] Instead we shall try to see just why and how an increase in the quantity of money raises prices.
An increased quantity of money comes into existence in a specific way. Let us say that it comes into existence because the government makes larger expenditures than it can or wishes to meet out of the proceeds of taxes (or from the sale of bonds paid for by the people out of real savings). Suppose, for example, that the government prints money to pay war contractors. Then the first effect of these expenditures will be to raise the prices of supplies used in war and to put additional money into the hands of the war contractors and their employees. (As, in our chapter on price-fixing, we deferred for the sake of simplicity some complications introduced by an inflation, so, in now considering inflation, we may pass over the complications introduced by an attempt at government price-fixing. When these are considered it will be found that they do not change the essential analysis. They lead merely to a sort of backed—up or “repressed” inflation that reduces or conceals some of the earlier consequences at the expense of aggravating the later ones.)
The war contractors and their employees, then, will have higher money incomes. They will spend them for the particular goods and services they want. The sellers of these goods and services will be able to raise their prices because of this increased demand. Those who have the increased money income will be willing to pay these higher prices rather than do without the goods; for they will have more money, and a dollar will have a smaller subjective value in the eyes of each of them.
Let us call the war contractors and their employees group A, and those from whom they directly buy their added goods and services group B. Group B, as a result of higher sales and prices, will now in turn buy more goods and services from a still further group, C. Group C in turn will be able to raise its prices and will have more income to spend on group D, and so on, until the rise in prices and money incomes has covered virtually the whole nation. When the process has been completed, nearly everybody will have a higher income measured in terms of money. But (assuming that production of goods and services has not increased) prices of goods and services will have increased correspondingly. The nation will be no richer than before.
This does not mean, however, that everyone’s relative or absolute wealth and income will remain the same as before. On the contrary, the process of inflation is certain to affect the fortunes of one group differently from those of another. The first groups to receive the additional money will benefit the most. The money incomes of group A, for example, will have increased before prices have increased, so that they will be able to buy almost a proportionate increase in goods. The money incomes of group B will advance later, when prices have already increased somewhat; but group B will be better off in terms of goods. Meanwhile, however, the groups that have still had no advance whatever in their money incomes will find themselves compelled to pay higher prices for the things they buy, which means that they will be obliged to get along on a lower standard of living than before.
We may clarify the process further by a hypothetical set of figures. Suppose we divide the community arbitrarily into four main groups of producers, A, B, C and D, who get the money income benefit of the inflation in that order. Then when money incomes of group A have already increased 30 percent, the prices of the things they purchase have not yet increased at all. By the time money incomes of group B have increased 20 percent, prices have still increased an average of only 10 percent. When money incomes of group C have increased only 10 percent, however, prices have already gone up 15 percent. And when money incomes of group D have not yet increased at all, the average prices they have to pay for the things they buy have gone up 20 percent. In other words, the gains of the first groups of producers to benefit by higher prices or wages from the inflation are necessarily at the expense of the losses suffered (as consumers) by the last groups of producers that are able to raise their prices or wages.
It may be that, if the inflation is brought to a halt after a few years, the final result will be, say, an average increase of 25 percent in money incomes, and an average increase in prices of an equal amount, both of which are fairly distributed among all groups. But this will not cancel out the gains and losses of the transition period. Group D, for example, even though its own incomes and prices have at last advanced 25 percent, will be able to buy only as much goods and services as before the inflation started. It will never compensate for its losses during that period when its income and prices had not risen at all, though it had to pay up to 30 percent more for the goods and services it bought from the other producing groups in the community, A, B and C.
