Chapter XI. Of Excess Of Supply.

§ 1. The theory of a general Over-Supply of Commodities stated.

After the elementary exposition of the theory of money contained in the

last few chapters, we shall return to a question in the general theory of

Value which could not be satisfactorily discussed until the nature and

operations of Money were in some measure understood, because the errors

against which we have to contend mainly originate in a misunderstanding of

those operations.

Because the phenomenon of over-supply and consequent inconvenience or loss

to the producer or dealer may exist in the case of any one commodity

whatever, many persons, including some distinguished political

economists,(255) have thought that it may exist with regard to all

commodities; that there may be a general over-production of wealth; a

supply of commodities in the aggregate surpassing the demand; and a

consequent depressed condition of all classes of producers.

The doctrine appears to me to involve so much inconsistency in its very

conception that I feel considerable difficulty in giving any statement of

it which shall be at once clear and satisfactory to its supporters. They

agree in maintaining that there may be, and sometimes is, an excess of

productions in general beyond the demand for them; that when this happens,

purchasers can not be found at prices which will repay the cost of

production with a profit; that there ensues a general depression of prices

or values (they are seldom accurate in discriminating between the two), so

that producers, the more they produce, find themselves the poorer instead

of richer; and Dr. Chalmers accordingly inculcates on capitalists the

practice of a moral restraint in reference to the pursuit of gain, while

Sismondi deprecates machinery and the various inventions which increase

productive power. They both maintain that accumulation of capital may

proceed too fast, not merely for the moral but for the material interest

of those who produce and accumulate; and they enjoin the rich to guard

against this evil by an ample unproductive consumption.

§ 2. The supply of commodities in general can not exceed the power of

Purchase.

When these writers speak of the supply of commodities as outrunning the

demand, it is not clear which of the two elements of demand they have in

view—the desire to possess, or the means of purchase; whether their

meaning is that there are, in such cases, more consumable products in

existence than the public desires to consume, or merely more than it is

able to pay for. In this uncertainty, it is necessary to examine both

suppositions.

It will be here noticed that Mr. Mill uses demand in the sense for

which we contended it should be used (Book III, Chap. I, § 3), and

not as “quantity demanded.” The present discussion of

over-production should also be connected by the student with the

former reference to it, Book I, Chap. IV, § 2.

First, let us suppose that the quantity of commodities produced is not

greater than the community would be glad to consume; is it, in that case,

possible that there should be a deficiency of demand for all commodities

for want of the means of payment? Those who think so can not have

considered what it is which constitutes the means of payment for

commodities. It is simply commodities. Each person’s means of paying for

the productions of other people consists of those which he himself

possesses. All sellers are inevitably and _ex vi termini_ buyers. Could we

suddenly double the productive powers of the country, we should double the

supply of commodities in every market; but we should, by the same stroke,

double the purchasing power.

Everybody would bring a double demand as well as supply; everybody would

be able to buy twice as much, because every one would have twice as much

to offer in exchange. It is probable, indeed, that there would now be a

superfluity of certain things. Although the community would willingly

double its aggregate consumption, it may already have as much as it

desires of some commodities, and it may prefer to do more than double its

consumption of others, or to exercise its increased purchasing power on

some new thing. If so, the supply will adapt itself accordingly, and the

values of things will continue to conform to their cost of production. At

any rate, it is a sheer absurdity that all things should fall in value,

and that all producers should, in consequence, be insufficiently

remunerated. If values remain the same, what becomes of prices is

immaterial, since the remuneration of producers does not depend on how

much money, but on how much of consumable articles, they obtain for their

goods. Besides, money is a commodity; and, if all commodities are supposed

to be doubled in quantity, we must suppose money to be doubled too, and

then prices would no more fall than values would.

§ 3. There can never be a lack of Demand arising from lack of Desire to

Consume.

A general over-supply, or excess of all commodities above the demand, so

far as demand consists in means of payment, is thus shown to be an

impossibility. But it may, perhaps, be supposed that it is not the ability

to purchase, but the desire to possess, that falls short, and that the

general produce of industry may be greater than the community desires to

consume—the part, at least, of the community which has an equivalent to

give.

This is much the most plausible form of the doctrine, and does not, like

that which we first examined, involve a contradiction. There may easily be

a greater quantity of any particular commodity than is desired by those

who have the ability to purchase, and it is abstractedly conceivable that

this might be the case with all commodities. The error is in not

perceiving that, though all who have an equivalent to give _might_ be

fully provided with every consumable article which they desire, the fact

that they go on adding to the production proves that this is not

_actually_ the case. Assume the most favorable hypothesis for the purpose,

that of a limited community, every member of which possesses as much of

necessaries and of all known luxuries as he desires, and, since it is not

conceivable that persons whose wants were completely satisfied would labor

and economize to obtain what they did not desire, suppose that a foreigner

arrives and produces an additional quantity of something of which there

was already enough. Here, it will be said, is over-production. True, I

reply; over-production of that particular article. The community wanted no

more of that, but it wanted something. The old inhabitants, indeed, wanted

nothing; but did not the foreigner himself want something? When he

produced the superfluous article, was he laboring without a motive? He has

produced—but the wrong thing instead of the right. He wanted, perhaps,

food, and has produced watches, with which everybody was sufficiently

supplied. The new-comer brought with him into the country a demand for

commodities equal to all that he could produce by his industry, and it was

his business to see that the supply he brought should be suitable to that

demand. If he could not produce something capable of exciting a new want

or desire in the community, for the satisfaction of which some one would

grow more food and give it to him in exchange, he had the alternative of

growing food for himself, either on fresh land, if there was any

unoccupied, or as a tenant, or partner, or servant of some former

occupier, willing to be partially relieved from labor. He has produced a

thing not wanted, instead of what was wanted, and he himself, perhaps, is

not the kind of producer who is wanted—but there is no over-production;

production is not excessive, but merely ill-assorted. We saw before that

whoever brings additional commodities to the market brings an additional

power of purchase; we now see that he brings also an additional desire to

consume, since if he had not that desire he would not have troubled

himself to produce. Neither of the elements of demand, therefore, can be

wanting when there is an additional supply, though it is perfectly

possible that the demand may be for one thing, and the supply may,

unfortunately, consist of another.

It is not sufficiently borne in mind, also, that the whole

progress of civilization results in a differentiation of new wants

and desires. To take but a single instance, with the growth of the

artistic sense the articles of common use change their entire

form; and the advances in the arts disclose new commodities which

satisfy the world’s desires, and for these new satisfactions

people are willing to work and produce in order to attain them.

With education also comes a wider horizon and a more refined

perception of taste, which creates wants for new things for which

the mind before had no desires. A little reflection, therefore,

must inevitably lead us to see that no person, no community, ever

had, or probably ever will have, all its wants satisfied. So far

as we know man, it does not seem possible that there will ever be

a falling off in demand, because of a satiety of all material

satisfactions.

§ 4. Origin and Explanation of the notion of general Over-Supply.

I have already described the state of the markets for commodities which

accompanies what is termed a commercial crisis. At such times there is

really an excess of all commodities above the money demand: in other

words, there is an under-supply of money. From the sudden annihilation of

a great mass of credit, every one dislikes to part with ready money, and

many are anxious to procure it at any sacrifice. Almost everybody,

therefore, is a seller, and there are scarcely any buyers: so that there

may really be, though only while the crisis lasts, an extreme depression

of general prices, from what may be indiscriminately called a glut of

commodities or a dearth of money. But it is a great error to suppose, with

Sismondi, that a commercial crisis is the effect of a general excess of

production. It is simply the consequence of an excess of speculative

purchases. It is not a gradual advent of low prices, but a sudden recoil

from prices extravagantly high: its immediate cause is a contraction of

credit, and the remedy is, not a diminution of supply, but the restoration

of confidence. It is also evident that this temporary derangement of

markets is an evil only because it is temporary. The fall being solely of

money prices, if prices did not rise again no dealer would lose, since the

smaller price would be worth as much to him as the larger price was

before. In no matter does this phenomenon answer to the description which

these celebrated economists have given of the evil of over-production.

That permanent decline in the circumstances of producers, for want of

markets, which those writers contemplate, is a conception to which the

nature of a commercial crisis gives no support.

The other phenomenon from which the notion of a general excess of wealth

and superfluity of accumulation seems to derive countenance is one of a

more permanent nature, namely, the fall of profits and interest which

naturally takes place with the progress of population and production. The

cause of this decline of profit is the increased cost of maintaining

labor, which results from an increase of population and of the demand for

food, outstripping the advance of agricultural improvement. This important

feature in the economical progress of nations will receive full

consideration and discussion in the succeeding book.(256) It is obviously

a totally different thing from a want of market for commodities, though

often confounded with it in the complaints of the producing and trading

classes. The true interpretation of the modern or present state of

industrial economy is, that there is hardly any amount of business which

may not be done, if people will be content to do it on small profits; and

this all active and intelligent persons in business perfectly well know:

but even those who comply with the necessities of their time grumble at

what they comply with, and wish that there were less capital,(257) or, as

they express it, less competition, in order that there might be greater

profits. Low profits, however, are a different thing from deficiency of

demand, and the production and accumulation which merely reduce profits

can not be called excess of supply or of production. What the phenomenon

really is, and its effects and necessary limits, will be seen when we

treat of that express subject.
