would soon appear, and if it did, the value would recede somewhat from excess of supply, until the production was reduced, and would then rise again. There are many articles for which it requires a very considerable rise of price, materially to reduce the demand; in particular, articles of necessity, such as the habitual food of the people ; in England, wheaten bread: of which there is probably almost as much consumed, at the present cost price, as there would be with the present population at a price considerably lower. Yet it is especially in such things that dearness or high price is popularly confounded with scarcity. Food may be dear from scarcity, as after a bad harvest; but the dearness (for example) which is the effect of taxation, or of corn laws, has nothing whatever to do with insufficient supply: such causes do not much diminish the quantity of food in a country: it is other things rather than food that are diminished in quantity by them, since, those who pay more for food not having so much to expend otherwise, the production of other things contracts itself to the limits of a smaller demand.

It is, therefore, strictly correct to say, that the value of things which can be increased in quantity at pleasure, does not depend (except accidentally, and during the time necessary for production to adjust itself,) upon demand and supply; on the contrary, demand and supply depend upon it. There is a demand for a certain quantity of the commodity at its natural or cost value, and to that the supply in the long run endeavours to conform. When at any time it fails of so conforming, it is either from miscalculation, or from a change in some of the elements of the problem: either in the natural value, that is, in the cost of production; or in the demand, from an alteration in public taste or in the number or wealth of the consumers. These causes of disturbance are very liable to occur, and when any one of them does occur, the market value of the article ceases to agree with the natural value. The real law of demand and supply, the equation between them, holds good in all cases: if a value different from the natural value be necessary to make the demand equal to the supply, the market value will deviate from the natural value; but only for a time; for the permanent tendency of supply is to conform itself to the demand which is found by experience to exist for the commodity when selling at its natural value. If the supply is either more or less than this, it is so accidentally, and affords either more or less than the ordinary rate of profit; which, under free and active competition, cannot long continue to be the case.

To recapitulate: demand and supply govern the value of all things which cannbTlie indefinitely increased; except that even for them, when produced by industry, there is a minimum value, determined by the cost of production. But in all things which admit of indefinite multiplication, demand and supply only determine the perturbations of value, during a period which cannot exceed the length of time necessary for altering the supply. While thus ruling the oscillations of value, they themselves obey a superior force, which makes value gravitate towards Cost of Production, and which would settle it and keep it there, if fresh disturbing influences were not continually arising to make it again deviate. To pursue the same strain of metaphor, demand and supply always rush to an equilibrium, but the condition of stable equilibrium is when things exchange for each other according to their cost of production, or, in the expression we have used, when things are at their Natural Value.



§ 1. The component elements of Cost of Production have been set forth in the First Part of this enquiry.* The principal of them, and so much the principal as to be nearly the sole, was found to be Labour. What the production of a thing costs to its producer, or its series of producers, is the labour expended in producing it. If we consider as the producer the capitalist who makes the advances, the word Labour may be replaced by the word Wages: what the produce costs to him, is the wages which he has had to pay. At the first glance indeed this seems to be only a part of his outlay, since he has not only paid wages to labourers, but has likewise provided them with tools, materials, and perhaps buildings. These tools, materials, and buildings, however, were produced by labour and capital; and their value, like that of the article to the production of which they are subservient, depends on cost of production, which again is resolvable into labour. The cost of production of broadcloth does not wholly consist in the wages of weavers; which alone are directly paid by the cloth manufacturer. It consists also of the wages of spinners and woolcombers, and it may be added, of shepherds, all of which the clothier has paid for in the price of yarn. It consists too of the wages of builders and brickmakers, which he has reimbursed in the contract price of erecting his factory. It partly consists of the wages of machine-makers, iron-found-. ers, and miners. And to these must be added the wages of the carriers who transported any of the means and appliances of the production to the place where they were to be used, and the product itself to the place where it is to be sold.

The value of commodities, therefore, depends principally (we shall presently see whether it depends solely) on the quantity of labour required for their production; including in the idea of production, that of conveyance to the market. "In estimating," says Ricardo,* "the exchangeable value of stockings, for example, we shall find that their value, comparatively with other things, depends on the total quantity of labour necessary to manufacture them and bring them to market. First, there is the labour necessary to cultivate the land on which the raw cotton is grown; secondly, the labour of conveying the cotton to the country where the stockings are to be manufactured, which includes a portion of the labour bestowed in building the ship in which it is conveyed, and which is charged in the freight of the goods; thirdly, the labour of the spinner and weaver; fourthly, a portion of the labour of the engineer, smith, and carpenter, who erected the buildings and machinery by the help of which they are made; fifthly, the labour of the retail dealer, and of many others, whom it is unnecessary further to particularize. The aggregate sum of these various kinds of labour, determines the quantity of other things for which these stockings will exchange, while the same consideration of the various quantities of labour which have been bestowed on those other things, will equally govern the portion of them which will be given for the stockings.

"To convince ourselves that this is the real foundation of exchangeable value, let us suppose any improvement to be made in the means of abridging labour in any one of the various processes through which the raw cotton must pass before the manufactured stockings come to the market to be exchanged for other things; and observe the effects which will follow. If fewer men were required to cultivate the raw cotton, or if fewer sailors were employed in navigating, or shipwrights in constructing, the ship in which it was conveyed to us; if fewer hands were employed in raising the buildings and machinery, or if these, when raised, were rendered more efficient; the stockings would inevitably fall in value, and command less of other things. They would fall, because a less quantity of labour was necessary to their production, and would therefore exchange for a smaller quantity of those things in which no such abridgment of labour had been made.

* Principles of Political Economy and Taxation, ch. i. sect. 3.

"Economy in the use of labour never fails to reduce the relative value of a commodity, whether the saving be in the labour necessary to the manufacture of the commodity itself, or in that necessary to the formation of the capital, by the aid of which it is produced. In either case the price of stockings would fall, whether there were fewer men employed as bleachers, spinners, and weavers, persons immediately necessary to their manufacture; or as sailors, carriers, engineers, and smiths, persons more indirectly concerned. In the one case, the whole saving of labour would fall on the stockings, because that portion of labour was wholly confined to the stockings; in the other, a portion only would fall on the stockings ; the remainder being applied o all those other commodities, to the production of which the buildings, machinery, and carriage, were subservient."

§ 2. It will have been observed that Ricardo expresses himself as if the quantity of labour which it costs to produce a commodity and bring it to market, were the only thing on which its value depended. But since the cost of production to the capitalist is not labour but wages, and since wages may be either greater or less, the quantity of labour being the same; it would seem that the value of the product cannot be determined solely by the quantity of labour, but by the quantity together with the remuneration; and that values must partly depend on wages.
