Principles of Political Economy with some of their Applications to Social Philosophy

As formerly observed,
*10 there are two kinds of agricultural improvements. Some consist in a mere saving of labour, and enable a given quantity of food to be produced at less cost, but not on a smaller surface of land than before. Others enable a given extent of land to yield not only the same produce with less labour, but a greater produce; so that, if no greater produce is required, a part of the land already under culture may be dispensed with. As the part rejected will be the least productive portion, the market will thenceforth be regulated by a better description of land than what was previously the worst under cultivation.

To place the effect of the improvement in a clear light, we must suppose it to take place suddenly, so as to leave no time, during its introduction, for any increase of capital or of population. Its first effect will be a fall of the value and price of agricultural produce. This is a necessary consequence of either kind of improvement, but especially of the last.

An improvement of the first kind, not increasing the produce, does not dispense with any portion of the land; the margin of cultivation (as Dr. Chalmers terms it) remains where it was; agriculture does not recede, either in extent of cultivated land, or in elaborateness of method: and the price continues to be regulated by the same land, and by the same capital, as before. But since that land or capital, and all other land or capital which produces food, now yields its produce at smaller cost, the price of food will fall proportionally. If one-tenth of the expense of production has been saved, the price of produce will fall one-tenth.

But suppose the improvement to be of the second kind; enabling the land to produce, not only the same corn with one-tenth less labour, but a tenth more corn with the same labour. Here the effect is still more decided. Cultivation can now be contracted, and the market supplied from a smaller quantity of land. Even if this smaller surface of land were of the same average quality as the larger surface, the price would fall one-tenth, because the same produce would be obtained with a tenth less labour. But since the portion of land abandoned will be the least fertile portion, the price of produce will thenceforth be regulated by a better quality of land than before. In addition, therefore, to the original diminution of one-tenth in the cost of production, there will be a further diminution, corresponding with the recession of the “margin” of agriculture to land of greater fertility. There will thus be a twofold fall of price.

Let us now examine the effect of the improvements, thus suddenly made, on the division of the produce; and in the first place, on rent. By the former of the two kinds of improvement, rent would be diminished. By the second, it would be diminished still more.

Suppose that the demand for food requires the cultivation of three qualities of land, yielding, on an equal surface, and at an equal expense, 100, 80, and 60 bushels of wheat. The price of wheat will, on the average, be just sufficient to enable the third quality to be cultivated with the ordinary profit. The first quality therefore will yield forty and the second twenty bushels of extra profit, constituting the rent of the landlord. And first, let an improvement be made, which, without enabling more corn to be grown, enables the same corn to be grown with one-fourth less labour. The price of wheat will fall one-fourth, and 80 bushels will be sold for the price for which 60 were sold before. But the produce of the land which produces 60 bushels is still required, and the expenses being as much reduced as the price, that land can still be cultivated with the ordinary profit. The first and second qualities will therefore continue to yield a surplus of 40 and 20 bushels, and corn rent will remain the same as before. But corn having fallen in price one-fourth, the same corn rent is equivalent to a fourth less of money and of all other commodities. So far, therefore, as the landlord expends his income in manufactured or foreign products, he is one-fourth worse off than before. His income as landlord is reduced to three-quarters of its amount: it is only as a consumer of corn that he is as well off.

If the improvement is of the other kind, rent will fall in a still greater ratio. Suppose that the amount of produce which the market requires, can be grown not only with a fourth less labour, but on a fourth less land. If all the land already in cultivation continued to be cultivated, it would yield a produce much larger than necessary. Land, equivalent to a fourth of the produce, must now be abandoned; and as the third quality yielded exactly one-fourth, (being 60 out of 240,) that quality will go out of cultivation. The 240 bushels can now be grown on land of the first and second qualities only; being, on the first, 100 bushels plus one-third, or 133 1/3 bushels; on the second, 80 bushels plus one-third, or 106 2/3 bushels; together 240. The second quality of land, instead of the third, is now the lowest, and regulates the price. Instead of 60, it is sufficient if 106 2/3 bushels repay the capital with the ordinary profit. The price of wheat will consequently fall, not in the ratio of 60 to 80, as in the other case, but in the ratio of 60 to 106 2/3. Even this gives an insufficient idea of the degree in which rent will be affected. The whole produce of the second quality of land will now be required to repay the expenses of production. That land, being the worst in cultivation, will pay no rent. And the first quality will only yield the difference between 133 1/3 bushels and 106 2/3, being 26 2/3 bushels instead of 40. The landlords collectively will have lost 33 1/3 out of 60 bushels in corn rent alone, while the value and price of what is left will have been diminished in the ratio of 60 to 106 2/3.

It thus appears, that the interest of the landlord is decidedly hostile to the sudden and general introduction of agricultural improvements. This assertion has been called a paradox, and made a ground for accusing its first promulgator, Ricardo, of great intellectual perverseness, to say nothing worse. I cannot discern in what the paradox consists; and the obliquity of vision seems to me to be on the side of his assailants. The opinion is only made to appear absurd by stating it unfairly. If the assertion were that a landlord is injured by the improvement of his estate, it would certainly be indefensible; but what is asserted is, that he is injured by the improvement of the estates of other people, although his own is included. Nobody doubts that he would gain greatly by the improvement if he could keep it to himself, and unite the two benefits, an increased produce from his land, and a price as high as before. But if the increase of produce took place simultaneously on all lands, the price would not be as high as before; and there is nothing unreasonable in supposing that the landlords would be, not benefited, but injured. It is admitted that whatever permanently reduces the price of produce diminishes rent: and it is quite in accordance with common notions to suppose that if, by the increased productiveness of land, less land were required for cultivation, its value, like that of other articles for which the demand had diminished, would fall.

I am quite willing to admit that rents have not really been lowered by the progress of agricultural improvement; but why? Because improvement has never in reality been sudden, but always slow; at no time much outstripping, and often falling far short of, the growth of capital and population, which tends as much to raise rent, as the other to lower it, and which is enabled, as we shall presently see, to raise it much higher, by means of the additional margin afforded by improvements in agriculture. First, however, we must examine in what manner the sudden cheapening of agricultural produce would affect profits and wages.

In the beginning, money wages would probably remain the same as before, and the labourers would have the full benefit of the cheapness. They would be enabled to increase their consumption either of food or of other articles, and would receive the same cost, and a greater quantity. So far, profits would be unaffected. But the permanent remuneration of the labourers essentially depends on what we have called their habitual standard; the extent of the requirements which, as a class, they insist on satisfying before they choose to have children. If their tastes and requirements receive a durable impress from the sudden improvement in their condition, the benefit to the class will be permanent. But the same cause which enables them to purchase greater comforts and indulgences with the same wages, would enable them to purchase the same amount of comforts and indulgences with lower wages; and a greater population may now exist, without reducing the labourers below the condition to which they are accustomed. Hitherto this and no other has been the use which the labourers have commonly made of any increase of their means of living; they have treated it simply as convertible into food for a greater number of children. It is probable, therefore, that population would be stimulated, and that after the lapse of a generation the real wages of labour would be no higher than before the improvement: the reduction being partly brought about by a fall of money wages, and partly through the price of food, the cost of which, from the demand occasioned by the increase of population, would be increased. To the extent to which money wages fell, profits would rise; the capitalist obtaining a greater quantity of equally efficient labour by the same outlay of capital. We thus see that a diminution of the cost of living, whether arising from agricultural improvements or from the importation of foreign produce, if the habits and requirements of the labourers are not raised, usually lowers money wages and rent, and raises the general rate of profit.

What is true of improvements which cheapen the production of food, is true also of the substitution of a cheaper for a more costly variety of it. The same land yields to the same labour a much greater quantity of human nutriment in the form of maize or potatoes, than in the form of wheat. If the labourers were to give up bread, and feed only on those cheaper products, taking as their compensation, not a greater quantity of other consumable commodities, but earlier marriages and larger families, the cost of labour would be much diminished, and if labour continued equally efficient, profits would rise; while rent would be much lowered, since food for the whole population could be raised on half or a third part of the land now sown with corn. At the same time, it being evident that land too barren to be cultivated for wheat might be made in case of necessity to yield potatoes sufficient to support the little labour necessary for producing them, cultivation might ultimately descend lower, and rent eventually rise higher, on a potato or maize system, than on a corn system; because the land would be capable of feeding a much larger population before reaching the limit of its powers.

If the improvement, which we suppose to take place, is not in the production of food, but of some manufactured article consumed by the labouring class, the effect on wages and profits will at first be the same; but the effect on rent very different. It will not be lowered; it will even, if the ultimate effect of the improvement is an increase of population, be raised: in which last case profits will be lowered. The reasons are too evident to require statement.

§5. We have considered, on the one hand, the manner in which the distribution of the produce into rent, profits, and wages, is affected by the ordinary increase of population and capital, and on the other, how it is affected by improvements in production, and more especially in agriculture. We have found that the former cause lowers profits; and raises rent and the cost of labour: while the tendency of agricultural improvements is to diminish rent; and all improvements which cheapen any article of the labourer’s consumption, tend to diminish the cost of labour and to raise profits. The tendency of each cause in its separate state being thus ascertained, it is easy to determine the tendency of the actual course of things, in which the two movements are going on simultaneously, capital and population increasing with tolerable steadiness, while improvements in agriculture are made from time to time, and the knowledge and practice of improved methods become diffused gradually through the community.

The habits and requirements of the labouring classes being given (which determine their real wages), rents, profits, and money wages at any given time, are the result of the composition of these rival forces. If during any period agricultural improvement advances faster than population, rent and money wages during that period will tend downward, and profits upward. If population advances more rapidly than agricultural improvement, either the labourers will submit to a reduction in the quantity or quality of their food, or if not, rent and money wages will progressively rise, and profits will fall.

Agricultural skill and knowledge are of slow growth, and still slower diffusion. Inventions and discoveries, too, occur only occasionally, while the increase of population and capital are continuous agencies. It therefore seldom happens that improvement, even during a short time, has so much the start of population and capital as actually to lower rent, or raise the rate of profits. There are many countries in which the growth of population and capital is not rapid, but in these agricultural improvement is less active still. Population almost everywhere treads close on the heels of agricultural improvement, and effaces its effects as fast as they are produced.

The reason why agricultural improvement seldom lowers rent, is that it seldom cheapens food, but only prevents it from growing dearer; and seldom, if ever, throws land out of cultivation, but only enables worse and worse land to be taken in for the supply of an increasing demand. What is sometimes called the natural state of a country which is but half cultivated, namely, that the land is highly productive, and food obtained in great abundance by little labour, is only true of unoccupied countries colonized by a civilized people. In the United States the worst land in cultivation is of a high quality (except sometimes in the immediate vicinity of markets or means of conveyance, where a bad quality is compensated by a good situation);
*11 and even if no further improvements were made in agriculture or locomotion, cultivation would have many steps yet to descend, before the increase of population and capital would be brought to a stand; but in Europe five hundred years ago, though so thinly peopled in comparison to the present population, it is probable that the worst land under the plough was, from the rude state of agriculture, quite as unproductive as the worst land now cultivated; and that cultivation had approached as near to the ultimate limit of profitable tillage, in those times as in the present. What the agricultural improvements since made have really done is, by increasing the capacity of production of land in general, to enable tillage to extend downwards to a much worse natural quality of land than the worst which at that time would have admitted of cultivation by a capitalist for profit; thus rendering a much greater increase of capital and population possible, and removing always a little and a little further off the barrier which restrains them; population meanwhile always pressing so hard against the barrier, that there is never any visible margin left for it to seize, every inch of ground made vacant for it by improvement being at once filled up by its advancing columns. Agricultural improvement may thus be considered to be not so much a counterforce conflicting with increase of population, as a partial relaxation of the bonds which confine that increase.

The effects produced on the division of the produce by an increase of production, under the joint influence of increase of population and capital and improvements of agriculture, are very different from those deduced from the hypothetical cases previously discussed. In particular, the effect on rent is most materially different. We remarked that—while a great agricultural improvement made suddenly and universally would in the first instance inevitably lower rent—such improvements enable rent, in the progress of society, to rise gradually to a much higher limit than it could otherwise attain, since they enable a much lower quality of land to be ultimately cultivated. But in the case we are now supposing, which nearly corresponds to the usual course of things, this ultimate effect becomes the immediate effect. Suppose cultivation to have reached, or almost reached, the utmost limit permitted by the state of the industrial arts, and rent, therefore, to have attained nearly the highest point to which it can be carried by the progress of population and capital, with the existing amount of skill and knowledge. If a great agricultural improvement were suddenly introduced, it might throw back rent for a considerable space, leaving it to regain its lost ground by the progress of population and capital, and afterwards to go on further. But, taking place, as such improvement always does, very gradually, it causes no retrograde movement of either rent or cultivation; it merely enables the one to go on rising, and the other extending, long after they must otherwise have stopped. It would do this even without the necessity of resorting to a worse quality of land; simply by enabling the lands already in cultivation to yield a greater produce, with no increase of the proportional cost. If, by improvements of agriculture, all the lands in cultivation could be made, even with double labour and capital, to yield a double produce, (supposing that in the meantime population increased so as to require this double quantity) all rents would be doubled.

To illustrate the point, let us revert to the numerical example in a former page. Three qualities of land yield respectively 100, 80, and 60 bushels to the same outlay on the same extent of surface. If No. 1 could be made to yield 200, No. 2, 160, and No. 3, 120 bushels, at only double the expense, and therefore without any increase of the cost of production, and if the population, having doubled, required all this increased quantity, the rent of No. 1 would be 80 bushels instead of 40, and of No. 2, 40 instead of 20, while the price and value per bushel would be the same as before: so that corn rent and money rent would both be doubled. I need not point out the difference between this result, and what we have shown would take place if there were an improvement in production without the accompaniment of an increased demand for food.

Agricultural improvement, then, is always ultimately, and in the manner in which it generally takes place also immediately, beneficial to the landlord. We may add, that when it takes place in that manner, it is beneficial to no one else. When the demand for produce fully keeps pace with the increased capacity of production, food is not cheapened; the labourers are not, even temporarily, benefited; the cost of labour is not diminished, nor profits raised. There is a greater aggregate production, a greater produce divided among the labourers, and a larger gross profit; but the wages being shared among a larger population, and the profits spread over a larger capital, no labourer is better off, nor does any capitalist derive from the same amount of capital a larger income.

The result of this long investigation may be summed up as follows. The economical progress of a society constituted of landlords, capitalists, and labourers, tends to the progressive enrichment of the landlord class;
*12 while the cost of the labourer’s subsistence tends on the whole to increase,
*13 and profits to fall. Agricultural improvements are a counteracting force to the two last effects; but the first, though a case is conceivable in which it would be temporarily checked, is ultimately in a high degree promoted by those improvements; and the increase of population tends to transfer all the benefits derived from agricultural improvement to the landlords alone. What other consequences, in addition to these, or in modification of them, arise from the industrial progress of a society thus constituted, I shall endeavour to show in the succeeding chapter.
