David Ricardo (1817)
'A MAN is rich or poor,' says Adam Smith, 'according to the degree in which he can afford to enjoy the necessaries, conveniences, and amusements of human life.'
Value, then, essentially differs from riches, for value depends not on abundance, but on the difficulty or facility of production. The labour of a million of men in manufactures, will always produce the same value, but will not always produce the same riches. By the invention of machinery, by improvements in skill, by a better division of labour, or by the discovery of new markets, where more advantageous exchanges may be made, a million of men may produce double, or treble the amount of riches, of 'necessaries, conveniences, and amusements,' in one state of society, that they could produce in another, but they will not on that account add any thing to value; for every thing rises or falls in value, in proportion to the facility or difficulty of producing it, or, in other words, in proportion to the quantity of labour employed on its production. Suppose with a given capital, the labour of a certain number of men produced 1,000 pair of stockings, and that by inventions in machinery, the same number of men can produce 2,000 pair, or that they can continue to produce 1,000 pair, and can produce besides 500 hats; then the value of the 2,000 pair of stockings, or of the 1,000 pair of stockings, and 500 hats, will be neither more nor less than that of the 1,000 pair of stockings before the introduction of machinery; for they will be the produce of the same quantity of labour. But the value of the general mass of commodities will nevertheless be diminished; for, although the value of the increased quantity produced, in consequence of the improvement, will be the same exactly as the value would have been of the less quantity that would have been produced, had no improvement taken place, an effect is also produced on the portion of goods still unconsumed, which were manufactured previously to the improvement; the value of those goods will be reduced, inasmuch as they must fall to the level, quantity for quantity, of the goods produced under all the advantages of the improvement: and the society will, notwithstanding the increased quantity of commodities, notwithstanding its augmented riches, and its augmented means of enjoyment, have a less amount of value. By constantly increasing the facility of production, we constantly diminish the value of some of the commodities before produced, though by the same means we not only add to the national riches, but also to the power of future production. Many of the errors in political economy have arisen from errors on this subject, from considering an increase of riches, and an increase of value, as meaning the same thing, and from unfounded notions as to what constituted a standard measure of value. One man considers money as a standard of value, and a nation grows richer or poorer, according to him, in proportion as its commodities of all kinds can exchange for more or less money. Others represent money as a very convenient medium for the purpose of barter, but not as a proper measure by which to estimate the value of other things; the real measure of value according to them, is corn,(43*) and a country is rich or poor, according as its commodities will exchange for more or less corn.(44*) There are others again, who consider a country rich or poor, according to the quantity of labour that it can purchase. But why should gold, or corn, or labour, be the standard measure of value, more than coals or iron? - more than cloth, soap, candles, and the other necessaries of the labourer? - why, in short, should any commodity, or all commodities together, be the standard, when such a standard is itself subject to fluctuations in value? Corn, as well as gold, may from difficulty or facility of production, vary 10, 20, or 30 per cent, relatively to other things; why should we always say, that it is those other things which have varied, and not the corn? That commodity is alone invariable, which at all times requires the same sacrifice of toil and labour to produce it. Of such a commodity we have no knowledge, but we may hypothetically argue and speak about it, as if we had; and may improve our knowledge of the science, by shewing distinctly the absolute inapplicability of all the standards which have been hitherto adopted. But supposing either of these to be a correct standard of value, still it would not be a standard of riches, for riches do not depend on value. A man is rich or poor, according to the abundance of necessaries and luxuries which he can command; and whether the exchangeable value of these for money, for corn, or for labour, be high or low, they will equally contribute to the enjoyment of their possessor. It is through confounding the ideas of value and wealth, or riches that it has been asserted, that by diminishing the quantity of commodities, that is to say of the necessaries, conveniences, and enjoyments of human life, riches may be increased. If value were the measure of riches, this could not be denied, because by scarcity the value of commodities is raised; but if Adam Smith be correct, if riches consist in necessaries and enjoyments, then they cannot be increased by a diminution of quantity.
It is true, that the man in possession of a scarce commodity is richer, if by means of it he can command more of the necessaries and enjoyments of human life; but as the general stock out of which each man's riches are drawn, is diminished in quantity, by all that any individual takes from it, other men's shares must necessarily be reduced in proportion as this favoured individual is able to appropriate a greater quantity to himself. Let water become scarce, says Lord Lauderdale, and be exclusively possessed by an individual, and you will increase his riches, because water will then have value; and if wealth be the aggregate of individual riches, you will by the same means also increase wealth. You undoubtedly will increase the riches of this individual, but inasmuch as the farmer must sell a part of his corn, the shoemaker a part of his shoes, and all men give up a portion of their possessions for the sole purpose of supplying themselves with water, which they before had for nothing, they are poorer by the whole quantity of commodities which they are obliged to devote to this purpose, and the proprietor of water is benefited precisely by the amount of their loss. The same quantity of water, and the same quantity of commodities, are enjoyed by the whole society, but they are differently distributed. This is, however, supposing rather a monopoly of water than a scarcity of it. If it should be scarce, then the riches of the country and of individuals would be actually diminished, inasmuch as it would be deprived of a portion of one of its enjoyments. The farmer would not only have less corn to exchange for the other commodities which might be necessary or desirable to him, but he, and every other individual, would be abridged in the enjoyment of one of the most essential of their comforts. Not only would there be a different distribution of riches, but an actual loss of wealth.
It may be said, then, of two countries possessing precisely the same quantity of all the necessaries and comforts of life, that they are equally rich, but the value of their respective riches would depend on the comparative facility or difficulty with which they were produced. For if an improved piece of machinery should enable us to make two pair of stockings, instead of one, without additional labour, double the quantity would be given in exchange for a yard of cloth. If a similar improvement be made in the manufacture of cloth, stockings and cloth will exchange in the same proportions as before, but they will both have fallen in value; for in exchanging them for hats, for gold, or other commodities in general, twice the former quantity must be given. Extend the improvement to the production of gold, and every other commodity; and they will all regain their former proportions. There will be double the quantity of commodities annually produced in the country, and therefore the wealth of the country will be doubled, but this wealth will not have increased in value.
Although Adam Smith has given the correct description of riches, which I have more than once noticed, he afterwards explains them differently, and says, 'that a man must be rich or poor according to the quantity of labour which he can afford to purchase.' Now, this description differs essentially from the other, and is certainly incorrect; for, suppose the mines were to become more productive, so that gold and silver fell in value, from the greater facility of their production; or that velvets were to be manufactured with so much less labour than before, that they fell to half their former value; the riches of all those who purchased those commodities would be increased; one man might increase the quantity of his plate, another might buy double the quantity of velvet; but with the possession of this additional plate and velvet, they could employ no more labour than before; because, as the exchangeable value of velvet and of plate would be lowered, they must part with proportionally more of these species of riches to purchase a day's labour. Riches, then, cannot be estimated by the quantity of labour which they can purchase.
From what has been said, it will be seen that the wealth of a country may be increased in two ways. it may be increased by employing a greater portion of revenue in the maintenance of productive labour, - which will not only add to the quantity, but to the value of the mass of commodities; or it may be increased, without employing any additional quantity of labour, by making the same quantity more productive, - which will add to the abundance, but not to the value of commodities
In the first case, a country would not only become rich, but the value of its riches would increase. It would become rich by parsimony. by diminishing its expenditure on objects of luxury and enjoyment; and employing those savings in reproduction.
In the second case, there will not necessarily be either any diminished expenditure on luxuries and enjoyments, or any increased quantity of productive labour employed, but with the same labour more would be produced; wealth would increase, but not value. Of these two modes of increasing wealth, the last must be preferred, since it produces the same effect without the privation and diminution of enjoyments, which can never fail to accompany the first mode. Capital is that part of the wealth of a country which is employed with a view to future production, and may be increased in the same manner as wealth. An additional capital will be equally efficacious in the production of future wealth, whether it be obtained from improvements in skill and machinery, or from using more revenue reproductively; for wealth always depends on the quantity of commodities produced, without any regard to the facility with which the instruments employed in production may have been procured. A certain quantity of clothes and provisions will maintain and employ the same number of men, and will therefore procure the same quantity of work to be done, whether they be produced by the labour of 100 or 200 men; but they will be of twice the value if 200 have been employed on their production.
M. Say, notwithstanding the corrections he has made in the fourth and last edition of his work, 'Traité d'Economie Politique,' appears to me to have been singularly unfortunate in his definition of riches and value. He considers these two terms as synonymous, and that a man is rich in proportion as he increases the value of his possessions, and is enabled to command an abundance of commodities. 'The value of incomes is then increased,' he observes, 'if they can procure, it does not signify by what means, a greater quantity of products.' According to M. Say, if the difficulty of producing cloth were to double, and consequently cloth was to exchange for double the quantity of the commodities for which it exchanged before, it would be doubled in value, to which I give my fullest assent; but if there were any peculiar facility in producing the commodities, and no increased difficulty in producing cloth, and cloth should in consequence exchange as before for double the quantity of commodities, M. Say would still say that cloth had doubled in value, whereas according to my view of the subject, he should say, that cloth retained its former value, and those particular commodities had fallen to half their former value. Must not M. Say be inconsistent with himself when he says, that by facility of production, two sacks of corn may be produced by the same means that one was produced before, and that each sack will therefore fall to half its former value, and yet maintain that the clothier who exchanges his cloth for two sacks of corn, will obtain double the value he before obtained, when he could only get one sack in exchange for his cloth. If two sacks be of the value that one was of before, he evidently obtains the same value and no more, - he gets, indeed, double the quantity of riches double the quantity of utility - double the quantity of what Adam Smith calls value in use, but not double the quantity of value, and therefore M. Say cannot be right in considering value, riches, and utility to be synonymous. Indeed, there are many parts of M. Say's work to which I can confidently refer in support of the doctrine which I maintain, respecting the essential difference between value and riches, although it must be confessed that there are also various other passages in which a contrary doctrine is maintained. These passages I cannot reconcile, and I point them out by putting them in opposition to each other, that M. Say may, if he should do me the honour to notice these observations in any future edition of his work, give such explanations of his views as may remove the difficulty, which many others, as well as myself, feel in our endeavours to expound them.

4. It is utility which determines the demand for a commodity, but it is the cost of it production which limit the extent of it demand. When it utility does not elevate its value to the level of the cost of production, the thing is not worth what it cost; it is a proof that the productive services might be employed to create a commodity of a superior value. The possessors of productive funds, that is to say, those who have the disposal of labour, of capital or land, are perpetually occupied in comparing the cost of production with the value of the things produced, or which comes to the same thing, in comparing the value of different commodities with each other; because the cost of production is nothing else but the value of productive services, consumed in forming a production; and the value of a productive service is nothing else than the value of the commodity, which is the result. The value of a commodity, the value of a productive service, the value of the cost of production are all, then, similar values when every thing is left to its natural course.

If there is no real dearness but that which arises from cost of production, (see 2.) how can a commodity be said to rise in value, (see 5.) if its cost of production be not increased? and merely because it will exchange for more of a cheap commodity for more of a commodity the cost of production of which has diminished? When I give 2,000 times more cloth for a pound of gold than I give for a pound of iron, does it prove that I attach 2,000 times more utility to gold than I do to iron? certainly not; it proves only as admitted by M. Say, (see 4.) that the cost of production of gold is 2,000 times greater than the cost of production of iron. If the cost of production of the two metals were the same, I should give the same price for them; but if utility were the measure of value, it is probable I should give more for the iron. It is the competition of the producers 'who are perpetually employed in comparing the cost of production with the value of the thing produced,' (see 4.) which regulates the value of different commodities. If, then, I give one shilling for a loaf, and 21 shillings for a guinea, it is no proof that this in my estimation is the comparative measure of their utility.
In No. 4, M. Say maintains with scarcely any variation, the doctrine which I hold concerning value. In his productive services, he includes the services rendered by land, capital, and labour; in mine I include only capital and labour, and wholly exclude land. Our difference proceeds from the different view which we take of rent: I always consider it as the result of a partial monopoly, never really regulating price, but rather as the effect of it. If all rent were relinquished by landlords, I am of opinion, that the commodities produced on the land would be no cheaper, because there is always a portion of the same commodities produced on land, for which no rent is or can be paid, as the surplus produce is only sufficient to pay the profits of stock.
To conclude, although no one is more disposed than I am to estimate highly the advantage which results to all classes of consumers, from the real abundance and cheapness of commodities, I cannot agree with M. Say, in estimating the value of a commodity, by the abundance of other commodities for which it will exchange; I am of the opinion of a very distinguished writer, M. Destutt de Tracy, who says, that 'To measure any one thing is to compare it with a determinate quantity of that same thing which we take for a standard of comparison, for unity. To measure, then to ascertain a length, a weight, a value, is to find how many times they contain metres, grammes, francs, in a word, unities of the same description.' A franc is not a measure of value for any thing, but for a quantity of the same metal of which francs are made, unless francs, and the thing to be measured, can be referred to some other measure which is common to both. This, I think, they can be, for they are both the result of labour.' and, therefore, labour is a common measure, by which their real as well as their relative value may be estimated. This also, I am happy to say, appears to be M. Destutt de Tracy's opinion.(45*) He says, 'as it is certain that our physical and moral faculties are alone our original riches, the employment of those faculties, labour of some kind, is our only original treasure, and that it is always from this employment, that all those things are created which we call riches, those which are the most necessary, as well as those which are the most purely agreeable. It is certain too, that all those things only represent the labour which has created them, and if they have a value, or even two distinct values, they can only derive them from that of the labour from which they emana
M. Say, in speaking of the excellences and imperfections of the great work of Adam Smith, imputes to him, as an error, that, he attributes to the labour of man alone, the power of producing value. A more correct analysis shews us that value is owing to the action of labour, or rather the industry of man, combined with the action of those agents which nature supplies, and with that of capital. His ignorance of this principle prevented him from establishing the true theory of the influence of machinery in the production of riches.'
In contradiction to the opinion of Adam Smith, M. Say, in the fourth chapter, speaks of the value which is given to commodities by natural agents, such as the sun, the air, the pressure of the atmosphere, &c., which are sometimes substituted for the labour of man, and sometimes concur with him in producing.(46*) But these natural agents, though they add greatly to value in use, never add exchangeable value, of which M. Say is speaking, to a commodity: as soon as by the aid of machinery, or by the knowledge of natural philosophy, you oblige natural agents to do the work which was before done by man, the exchangeable value of such work falls accordingly. If ten men turned a corn mill, and it be discovered that by the assistance of wind, or of water, the labour of these ten men may be spared, the flour which is the produce partly of the work performed by the mill, would immediately fall in value, in proportion to the quantity of labour saved; and the society would be richer by the commodities which the labour of the ten men could produce, the funds destined for their maintenance being in no degree impaired. M. Say constantly overlooks the essential difference that there is between value in use, and value in exchange.
M. Say accuses Dr Smith of having overlooked the value which is given to commodities by natural agents, and by machinery, because he considered that the value of all things was derived from the labour of man; but it does not appear to me, that this charge is made out; for Adam Smith nowhere undervalues the services which these natural agents and machinery perform for us, but he very justly distinguishes the nature of the value which they add to commodities - they are serviceable to us, by increasing the abundance of productions, by making men richer, by adding to value in use; but as they perform their work gratuitously, as nothing is paid for the use of air, of heat, and of water, the assistance which they afford us, adds nothing to value in exchange.
