On The Principles of Political Economy, and Taxation

by David Ricardo

The second cause of rent mentioned by Mr. Malthus, namely, "that quality peculiar to the necessaries of life, of being able to create their own demand, or to raise up a number of demanders in proportion to the quantity of necessaries produced," does not appear to me to be any way essential to it. It is not the abundance of necessaries which raises up demanders, but the abundance of demanders which raises up necessaries.

We are under no necessity of producing permanently any greater quantity of a commodity than that which is demanded. If by accident any greater quantity were produced, it would fall below its natural price, and therefore would not pay the cost of production, together with the usual and ordinary profits of stock: thus the supply would be checked till it conformed to the demand, and the market price rose to the natural price.

Mr. Malthus appears to me to be too much inclined to think that population is only increased by the previous provision of food,—"that it is food that creates its own demand,"—that it is by first providing food that encouragement is given to marriage, instead of considering that the general progress of population is affected by the increase of capital, the consequent demand for labour, and the rise of wages; and that the production of food is but the effect of that demand.

It is by giving the workman more money, or any other commodity in which wages are paid, and which has not fallen in value, that his situation is improved. The increase of population, and the increase of food will generally be the effect, but not the necessary effect of high wages. The amended condition of the labourer, in consequence of the increased value which is paid him, does not necessarily oblige him to marry and take upon himself the charge of a family—he may, if it please him, exchange his increased wages for any commodities that may contribute to his enjoyments—for chairs, tables, and hardware; or for better clothes, sugar, and tobacco. His increased wages then will be attended with no other effect than an increased demand for some of those commodities; and as the race of labourers will not be materially increased, his wages will continue permanently high. But although this might be the consequence of high wages, yet so great are the delights of domestic society, that in practice it is invariably found that an increase of population follows the amended condition of the labourer; and it is only because it does so, that a new and increased demand arises for food. This demand then is the effect of an increase of population, but not the cause—it is only because the expenditure of the people takes this direction, that the market price of necessaries exceeds the natural price, and that the quantity of food required is produced; and it is because the number of people is increased, that wages again fall.

What motive can a farmer have to produce more corn than is actually demanded, when the consequence would be a depression of its market price below its natural price, and consequently a privation to him of a portion of his profits, by reducing them below the general rate? "If," says Mr. Malthus, "the necessaries of life, the most important products of land, had not the property of creating an increase of demand proportioned to their increased quantity, such increased quantity would occasion a fall in their exchangeable value.[52] However abundant might be the produce of a country, its population might remain stationary. And this abundance without a proportionate demand, and with a very high corn price of labour, which would naturally take place under these circumstances, might reduce the price of raw produce, like the price of manufactures, to the cost of production."

"Might reduce the price of raw produce to the cost of production?" Is it ever for any length of time either above or below this price? Does not Mr. Malthus himself, state it never to be so? "I hope," he says, "to be excused for dwelling a little, and presenting to the reader in various forms the doctrine, that corn, in reference to the quantity actually produced, is sold at its necessary price like manufactures, because I consider it as a truth of the highest importance, which has been overlooked by the economists, by Adam Smith, and all those writers, who have represented raw produce as selling always at a monopoly price."

"Every extensive country may thus be considered as possessing a gradation of machines for the production of corn and raw materials, including in this gradation not only all the various qualities of poor land, of which every territory has generally an abundance, but the inferior machinery which may be said to be employed when good land is further and further forced for additional produce. As the price of raw produce continues to rise, these inferior machines are successively called into action; and as the price of raw produce continues to fall, they are successively thrown out of action. The illustration here used serves to shew at once the necessity of the actual price of corn to the actual produce, and the different effect which would attend a great reduction in the price of any particular manufacture, and a great reduction in the price of raw produce."[53]

How are these passages to be reconciled to that which affirms, that if the necessaries of life had not the property of creating an increase of demand proportioned to their increased quantity, the abundant quantity produced would then, and then only, reduce the price of raw produce to the cost of production? If corn is never under its natural price, it is never more abundant than the actual population require it to be for their own consumption; no store can be laid up for the consumption of others; it can never then by its cheapness and abundance be a stimulus to population. In proportion as corn can be produced cheaply, the increased wages of the labourers will have more power to maintain families. In America, population increases rapidly, because food can be produced at a cheap price, and not because an abundant supply has been previously provided. In Europe population increases comparatively slowly, because food cannot be produced at a cheap value. In the usual and ordinary course of things, the demand for all commodities precedes their supply. By saying, that corn would, like manufactures, sink to its price of production, if it could not raise up demanders, Mr. Malthus cannot mean that all rent would be absorbed; for he has himself justly remarked, that if all rent were given up by the landlords, corn would not fall in price; rent being the effect, and not the cause of high price, and there being always one quality of land in cultivation which pays no rent whatever, the corn from which replaces by its price, only wages and profits.

In the following passage, Mr. Malthus has given an able exposition of the causes of the rise in the price of raw produce in rich and progressive countries, in every word of which I concur; but it appears to me to be at variance with some of the propositions maintained by him in some parts of his Essay on Rent. "I have no hesitation in stating, that, independently of the irregularities in the currency of a country, and other temporary and accidental circumstances, the cause of the high comparative money price of corn is its high comparative real price, or the greater quantity of capital and labour which must be employed to produce it; and that the reasons why the real price of corn is higher, and continually rising in countries which are already rich, and still advancing in prosperity and population, is to be found in the necessity of resorting constantly to poorer land, to machines which require a greater expenditure to work them, and which consequently occasion each fresh addition to the raw produce of the country to be purchased at a greater cost; in short, it is to be found in the important truth, that corn in a progressive country, is sold at the price necessary to yield the actual supply; and that, as this supply becomes more and more difficult, the price rises in proportion."
