On The Principles of Political Economy, and Taxation Part 3

and while I employed these portions, the rent would remain the same, although the produce of each should have an equal augmentation. If, instead of 100, 90, 80, 70, the produce should be increased to 125, 115, 105, 95, the rent would still be 60, or the difference between

95 and 125 = 30 } { 125 95 and 115 = 20 } whilst the produce { 115 95 and 105 = 10 } would be increased { 105 -- } to 440 { 95 60 } { --- { 440

But with such an increase of produce, without an increase of demand, there could be no motive for employing so much capital on the land; one portion would be withdrawn, and consequently the last portion of capital would yield 105 instead of 95, and rent would fall to 30, or the difference between

105 and 125 = 20 } whilst the produce would be still { 125 105 and 115 = 10 } adequate to the wants of the { 115 -- } population, for it would be 345 { 105 30 } quarters, or { --- { 345

the demand being only for 340 quarters.--But there are improvements which may lower the relative value of produce without lowering the corn rent, though they will lower the money rent of land. Such improvements do not increase the productive powers of the land, but they enable us to obtain its produce with less labour. They are rather directed to the formation of the capital applied to the land, than to the cultivation of the land itself. Improvements in agricultural implements, such as the plough and the thres.h.i.+ng machine, economy in the use of horses employed in husbandry, and a better knowledge of the veterinary art, are of this nature. Less capital, which is the same thing as less labour, will be employed on the land; but to obtain the same produce, less land cannot be cultivated. Whether improvements of this kind, however, affect corn rent, must depend on the question, whether the difference between the produce obtained by the employment of different portions of capital be increased, stationary, or diminished. If four portions of capital, 50, 60, 70, 80, be employed on the land, giving each the same results, and any improvement in the formation of such capital should enable me to withdraw 5 from each, so that they should be 45, 55, 65, and 75, no alteration would take place in the corn rent; but if the improvements were such as to enable me to make the whole saving on the largest portion of capital, that portion which is least productively employed, corn rent would immediately fall, because the difference between the capital most productive and the capital least productive would be diminished; and it is this difference which const.i.tutes rent.

Without multiplying instances, I hope enough has been said to shew, that whatever diminishes the inequality in the produce obtained from successive portions of capital employed on the same or on new land, tends to lower rent; and that whatever increases that inequality, necessarily produces an opposite effect, and tends to raise it.

In speaking of the rent of the landlord, we have rather considered it as the proportion of the whole produce, without any reference to its exchangeable value; but since the same cause, the difficulty of production, raises the exchangeable value of raw produce, and raises also the proportion of raw produce paid to the landlord for rent, it is obvious that the landlord is doubly benefited by difficulty of production. First he obtains a greater share, and secondly the commodity in which he is paid is of greater value.[8]

CHAPTER III.

ON THE RENT OF MINES.

The metals, like other things, are obtained by labour. Nature, indeed, produces them; but it is the labour of man which extracts them from the bowels of the earth, and prepares them for our service.

Mines, as well as land, generally pay a rent to their owner; and this rent, as well as the rent of land, is the effect, and never the cause of the high value of their produce.

If there were abundance of equally fertile mines, which any one might appropriate, they could yield no rent; the value of their produce would depend on the quant.i.ty of labour necessary to extract the metal from the mine and bring it to market.

But there are mines of various qualities, affording very different results, with equal quant.i.ties of labour. The metal produced from the poorest mine that is worked, must at least have an exchangeable value, not only sufficient to procure all the clothes, food, and other necessaries consumed by those employed in working it, and bringing the produce to market, but also to afford the common and ordinary profits to him who advances the stock necessary to carry on the undertaking. The return for capital from the poorest mine paying no rent, would regulate the rent of all the other more productive mines. This mine is supposed to yield the usual profits of stock. All that the other mines produce more than this, will necessarily be paid to the owners for rent. Since this principle is precisely the same as that which we have already laid down respecting land, it will not be necessary further to enlarge on it.

It will be sufficient to remark, that the same general rule which regulates the value of raw produce and manufactured commodities, is applicable also to the metals; their value depending not on the rate of profits, nor on the rate of wages, nor on the rent paid for mines, but on the total quant.i.ty of labour necessary to obtain the metal, and to bring it to market.

Like every other commodity, the value of the metals is subject to variation. Improvements may be made in the implements and machinery used in mining, which may considerably abridge labour; new and more productive mines may be discovered, in which, with the same labour, more metal may be obtained; or the facilities of bringing it to market may be increased. In either of these cases the metals would fall in value, and would therefore exchange for a less quant.i.ty of other things. On the other hand, from the increasing difficulty of obtaining the metal, occasioned by the greater depth at which the mine must be worked, and the acc.u.mulation of water, or any other contingency, its value, compared with that of other things, might be considerably increased.

It has therefore been justly observed, that however honestly the coin of a country may conform to its standard, money made of gold and silver is still liable to fluctuations in value, not only to accidental and temporary, but to permanent and natural variations, in the same manner as other commodities.

By the discovery of America and the rich mines in which it abounds, a very great effect was produced on the natural price of the precious metals. This effect is by many supposed not yet to have terminated. It is probable however that all the effects on the value of the metals, resulting from the discovery of America have long ceased, and if any fall has of late years taken place in their value, it is to be attributed to improvements in the mode of working the mines.

From whatever cause it may have proceeded, the effect has been so slow and gradual, that little practical inconvenience has been felt from gold and silver being the general medium in which the value of all other things is estimated. Though undoubtedly a variable measure of value, there is probably no commodity subject to fewer variations. This and the other advantages which these metals possess, such as their hardness, their malleability, their divisibility, and many more, have justly secured the preference every where given to them, as a standard for the money of civilized countries.

Having acknowledged the imperfections to which money made of gold and silver is liable as a measure of value, from the greater or less quant.i.ty of labour which may, under varying circ.u.mstances, be necessary for the production of those metals, we may be permitted to make the supposition that all these imperfections were removed, and that equal quant.i.ties of labour could at all times obtain, from that mine which paid no rent, equal quant.i.ties of gold. Gold would then be an invariable measure of value. The quant.i.ty indeed would enlarge with the demand, but its value would be invariable, and it would be eminently well calculated to measure the varying value of all other things. I have already in a former part of this work considered gold as endowed with this uniformity, and in the following chapter I shall continue the supposition. In speaking therefore of varying price, the variation will be always considered as being in the commodity, and never in the medium in which it is estimated.

CHAPTER IV.

ON NATURAL AND MARKET PRICE.

In making labour the foundation of the value of commodities, and the comparative quant.i.ty of labour which is necessary to their production, the rule which determines the respective quant.i.ties of goods which shall be given in exchange for each other, we must not be supposed to deny the accidental and temporary deviations of the actual or market price of commodities from this, their primary and natural price.

In the ordinary course of events, there is no commodity which continues for any length of time to be supplied precisely in that decree of abundance, which the wants and wishes of mankind require, and therefore there is none which is not subject to accidental and temporary variations of price.

It is only in consequence of such variations, that capital is apportioned precisely, in the requisite abundance and no more, to the production of the different commodities which happen to be in demand.

With the rise or fall of price, profits are elevated above, or depressed below their general level, and capital is either encouraged to enter into, or is warned to depart from the particular employment in which the variation has taken place.

Whilst every man is free to employ his capital where he pleases, he will naturally seek for it that employment which is most advantageous; he will naturally be dissatisfied with a profit of 10 per cent., if by removing his capital he can obtain a profit of 15 per cent. This restless desire on the part of all the employers of stock, to quit a less profitable for a more advantageous business, has a strong tendency to equalize the rate of profits of all, or to fix them in such proportions, as may in the estimation of the parties, compensate for any advantage which one may have, or may appear to have over the other.

It is perhaps very difficult to trace the steps by which this change is effected: it is probably effected, by a manufacturer not absolutely changing his employment, but only lessening the quant.i.ty of capital he has in that employment. In all rich countries, there is a number of men forming what is called the monied cla.s.s; these men are engaged in no trade, but live on the interest of their money, which is employed in discounting bills, or in loans to the more industrious part of the community. The bankers too employ a large capital on the same objects.

The capital so employed forms a circulating capital of a large amount, and is employed, in larger or smaller proportions, by all the different trades of a country. There is perhaps no manufacturer, however rich, who limits his business to the extent that his own funds alone will allow: he has always some portion of this floating capital, increasing or diminis.h.i.+ng according to the activity of the demand for his commodities.

When the demand for silks increases, and that for cloth diminishes, the clothier does not remove with his capital to the silk trade, but he dismisses some of his workmen, he discontinues his demand for the loan from bankers and monied men; while the case of the silk manufacturer is the reverse: he wishes to employ more workmen, and thus his motive for borrowing is increased: he borrows more, and thus capital is transferred from one employment to another, without the necessity of a manufacturer discontinuing his usual occupation. When we look to the markets of a large town, and observe how regularly they are supplied both with home and foreign commodities, in the quant.i.ty in which they are required, under all the circ.u.mstances of varying demand, arising from the caprice of taste, or a change in the amount of population, without often producing either the effects of a glut from a too abundant supply, or an enormously high price from the supply being unequal to the demand, we must confess that the principle which apportions capital to each trade in the precise amount that it is required, is more active than is generally supposed.

A capitalist, in seeking profitable employment for his funds, will naturally take into consideration all the advantages which one occupation possesses over another. He may therefore be willing to forego a part of his money profit, in consideration of the security, cleanliness, ease, or any other real or fancied advantage which one employment may possess over another.

If from a consideration of these circ.u.mstances, the profits of stock should be so adjusted that in one trade they were 20, in another 25, and in another 30 per cent., they would probably continue permanently with that relative difference, and with that difference only; for if any cause should elevate the profits of one of these trades 10 per cent.

either these profits would be temporary, and would soon again fall back to their usual station, or the profits of the others would be elevated in the same proportion.

Let us suppose that all commodities are at their natural price, and consequently that the profits of capital in all employments are exactly at the same rate, or differ only so much as, in the estimation of the parties, is equivalent to any real or fancied advantage which they possess or forego. Suppose now, that a change of fas.h.i.+on should increase the demand for silks, and lessen that for woollens; their natural price, the quant.i.ty of labour necessary to their production, would continue unaltered, but the market price of silks would rise, and that of woollens would fall; and consequently the profits of the silk manufacturer would be above, whilst those of the woollen manufacturer would be below, the general and adjusted rate of profits. Not only the profits, but the wages of the workmen would be affected in these employments. This increased demand for silks would however soon be supplied, by the transference of capital and labour from the woollen to the silk manufacture; when the market prices of silks and woollens would again approach their natural prices, and then the usual profits would be obtained by the respective manufacturers of those commodities.

It is then the desire, which every capitalist has, of diverting his funds from a less to a more profitable employment, that prevents the market price of commodities from continuing for any length of time either much above, or much below their natural price. It is this compet.i.tion which so adjusts the exchangeable value of commodities, that after paying the wages for the labour necessary to their production, and all other expenses required to put the capital employed in its original state of efficiency, the remaining value or overplus will in each trade be in proportion to the value of the capital employed.

In the 7th chap. of the Wealth of Nations, all that concerns this question is most ably treated. Having fully acknowledged the temporary effects which, in particular employments of capital, may be produced on the prices of commodities, as well as on the wages of labour, and the profits of stock, by accidental causes, without influencing the general price of commodities, wages, or profits, since these effects are equally operative in all stages of society, we may be permitted to leave them entirely out of our consideration, whilst we are treating of the laws which regulate natural prices, natural wages, and natural profits, effects totally independent of these accidental causes. In speaking then of the exchangeable value of commodities, or the power of purchasing possessed by any one commodity, I mean always that power which it would possess, if not disturbed by any temporary or accidental cause, and which is its natural price.

CHAPTER V.

ON WAGES

Labour, like all other things which are purchased and sold, and which may be increased or diminished in quant.i.ty, has its natural and its market price. The natural price of labour is that price which is necessary to enable the labourers, one with another, to subsist and to perpetuate their race, without either increase or diminution.

The power of the labourer to support himself, and the family which may be necessary to keep up the number of labourers, does not depend on the quant.i.ty of money, which he may receive for wages; but on the quant.i.ty of food, necessaries, and conveniences become essential to him from habit, which that money will purchase. The natural price of labour, therefore, depends on the price of the food, necessaries, and conveniences required for the support of the labourer and his family.

With a rise in the price of food and necessaries, the natural price of labour will rise; with the fall in their price, the natural price of labour will fall.

With the progress of society, the natural price of labour has always a tendency to rise, because one of the princ.i.p.al commodities by which its natural price is regulated, has a tendency to become dearer, from the greater difficulty of producing it. As, however, the improvements in agriculture, the discovery of new markets, whence provisions may be imported, may for a time counteract the tendency to a rise in the price of necessaries, and may even occasion their natural price to fall, so will the same causes produce the correspondent effects on the natural price of labour.

The natural price of all commodities excepting raw produce and labour has a tendency to fall, in the progress of wealth and population; for though, on one hand, they are enhanced in real value, from the rise in the natural price of the raw material of which they are made, this is more than counterbalanced by the improvements in machinery, by the better division and distribution of labour, and by the increasing skill, both in science and art, of the producers.

The market price of labour is the price which is really paid for it, from the natural operation of the proportion of the supply to the demand; labour is dear when it is scarce, and cheap when it is plentiful. However much the market price of labour may deviate from its natural price, it has, like commodities, a tendency to conform to it.

It is when the market price of labour exceeds its natural price, that the condition of the labourer is flouris.h.i.+ng and happy, that he has it in his power to command a greater proportion of the necessaries and enjoyments of life, and therefore to rear a healthy and numerous family.

When however, by the encouragement which high wages give to the increase of population, the number of labourers is increased, wages again fall to their natural price, and indeed from a re-action sometimes fall below it.

When the market price of labour is below its natural price, the condition of the labourers is most wretched: then poverty deprives them of those comforts which custom renders absolute necessaries. It is only after their privations have reduced their number, or the demand for labour has increased, that the market price of labour will rise to its natural price, and that the labourer will have the moderate comforts, which the natural price of wages will afford.

Notwithstanding the tendency of wages to conform to their natural rate, their market rate may, in an improving society, for an indefinite period, be constantly above it; for no sooner may the impulse, which an increased capital gives to a new demand for labour be obeyed, than another increase of capital may produce the same effect; and thus if the increase of capital be gradual and constant, the demand for labour may give a continued stimulus to an increase of people.
