So many fallacies have grown up about saving in recent years that they cannot all be answered by our example of the two brothers. It is necessary to devote some further space to them. Many stem from confusions so elementary as to seem incredible, particularly when found in the works of economic writers of wide repute. The word saving, for example, is used sometimes to mean mere hoarding of money, and sometimes to mean investment, with no clear distinction, consistently maintained, between the two uses.
Mere hoarding of hand-to-hand money, if it takes place irrationally, causelessly, and on a large scale, is in most economic situations harmful. But this sort of hoarding is extremely rare. Something that looks like this, but should be carefully distinguished from it, often occurs after a downturn in business has got under way. Consumptive spending and investment are then both contracted. Consumers reduce their buying. They do this partly, indeed, because they fear they may lose their jobs, and they wish to conserve their resources: they have contracted their buying not because they wish to consume less but because they wish to make sure that their power to consume will be extended over a longer period if they do lose their jobs.
But consumers reduce their buying for another reason. Prices of goods have probably fallen, and they fear a further fall. If they defer spending, they believe they will get more for their money. They do not wish to have their resources in goods that are falling in value, but in money which they expect (relatively) to rise in value.
The same expectation prevents them from investing. They have lost their confidence in the profitability of business; or at least they believe that if they wait a few months they can buy stocks or bonds cheaper. We may think of them either as refusing to hold goods that may fall in value on their hands, or as holding money itself for a rise.
It is a misnomer to call this temporary refusal to buy “saving.” It does not spring from the same motives as normal saving. And it is a still more serious error to say that this sort of “saving” is the cause of depressions. It is, on the contrary, the consequence of depressions.
It is true that this refusal to buy may intensify and prolong a depression. At times when there is capricious government intervention in business, and when business does not know what the government is going to do next, uncertainty is created. Profits are not reinvested. Firms and individuals allow cash balances to accumulate in their banks. They keep larger reserves against contingencies. This hoarding of cash may seem like a cause of a subsequent slowdown in business activity. The real cause, however, is the uncertainty brought about by the government policies. The larger cash balances of firms and individuals are merely one link in the chain of consequences from that uncertainty. To blame “excessive saving” for the business decline would be like blaming a fall in the price of apples not on a bumper crop but on the people who refuse to pay more for apples.
But when once people have decided to deride a practice or an institution, any argument against it, no matter how illogical, is considered good enough. It is said that the various consumers goods industries are built on the expectation of a certain demand, and that if people take to saving they will disappoint this expectation and start a depression. This assertion rests primarily on the error we have already examined—that of forgetting that what is saved on consumers’ goods is spent on capital goods, and that “saving” does not necessarily mean even a dollar’s contraction in total spending. The only element of truth in the contention is that any change that is sudden may be unsettling. It would be just as unsettling if consumers suddenly switched their demand from one consumers’ good to another. It would be even more unsettling if former savers suddenly switched their demand from capital goods to consumers’ goods
Still another objection is made against saving. It is said to be just downright silly. The nineteenth century is derided for its supposed inculcation of the doctrine that mankind through saving should go on baking itself a larger and larger cake without ever eating the cake. This picture of the process is itself naive and childish. It can best be disposed of, perhaps, by putting before ourselves a somewhat more realistic picture of what actually takes place.
Let us picture to ourselves, then, a nation that collectively saves every year about 20 percent of all it produces in that year. This figure greatly overstates the amount of net saving that has occurred historically in the United States,[*] but it is a round figure that is easily handled, and it gives the benefit of every doubt to those who believe that we have been “oversaving.”
Now as a result of this annual saving and investment, the total annual production of the country will increase each year. (To isolate the problem we are ignoring for the moment booms, slumps, or other fluctuations.) Let us say that this annual increase in production is 2.5 percentage points. (Percentage points are taken instead of a compounded percentage merely to simplify the arithmetic.) The picture that we get for an eleven-year period, say, would then run something like this in terms of index numbers:
| Year | Total Production | Consumers' Goods Production | Capital Goods Production |
|---|---|---|---|
| First | 100 | 80 | 20[†] |
| Second | 102.5 | 82 | 20.5 |
| Third | 105 | 84 | 21 |
| Fourth | 107.5 | 86 | 21.5 |
| Fifth | 110 | 88 | 22 |
| Sixth | 112.5 | 90 | 22.5 |
| Seventh | 115 | 92 | 23 |
| Eighth | 117.5 94 | 94 | 23.5 |
| Ninth | 120 | 96 | 24 |
| Tenth | 122.5 | 98 | 24.5 |
| Eleventh | 125 | 100 | 25 |
The first thing to be noticed about this table is that total production increases each year because of the saving, and would not have increased without it. (It is possible no doubt to imagine that improvements and new inventions merely in replaced machinery and other capital goods of a value no greater than the old would increase the national productivity; but this increase would amount to very little and the argument in any case assumes enough prior investment to have made the existing machinery possible.) The saving has been used year after year to increase the quantity or improve the quality of existing machinery, and so to increase the nation’s output of goods. There is, it is true (if that for some strange reason is considered an objection), a larger and larger “cake” each year. Each year, it is true, not all of the currently produced cake is consumed. But there is no irrational or cumulative restraint. For each year a larger and larger cake is in fact consumed; until, at the end of eleven years (in our illustration), the annual consumers’ cake alone is equal to the combined consumers’ and producers’ cakes of the first year. Moreover, the capital equipment, the ability to produce goods, is itself 25 percent greater than in the first year.
Let us observe a few other points. The fact that 20 percent of the national income goes each year for saving does not upset the consumers’ goods industries in the least. If they sold only the 80 units they produced in the first year (and there were no rise in prices caused by unsatisfied demand) they would certainly not be foolish enough to build their production plans on the assumption that they were going to sell 100 units in the second year. The consumers’ goods industries, in other words, are already geared to the assumption that the past situation in regard to the rate of savings will continue. Only an unexpected sudden and substantial increase in savings would unsettle them and leave them with unsold goods.
But the same unsettlement, as we have already observed, would be caused in the capital goods industries by a sudden and substantial decrease in savings. If money that would previously have been used for savings were thrown into the purchase of consumers goods, it would not increase employment but merely lead to an increase in the price of consumption goods and to a decrease in the price of capital goods. Its first effect on net balance would be to force shifts in employment and temporarily to decrease employment by its effect on the capital goods industries. And its long-run effect would be to reduce production below the level that would otherwise have been achieved.
