Principles Of Political Economy

§ 1. Different Theories as to the fall of Profits.

The tendency of profits to fall as society advances, which has been brought to notice in the preceding chapter, was early recognized by writers on industry and commerce; but, the laws which govern profits not being then understood, the phenomenon was ascribed to a wrong cause. Adam Smith considered profits to be determined by what he called the competition of capital. In Adam Smith's opinion, the manner in which the competition of capital lowers profits is by lowering prices; that being usually the mode in which an increased investment of capital in any particular trade lowers the profits of that trade. But, if this was his meaning, he overlooked the circumstance that the fall of price, which, if confined to one commodity, really does lower the profits of the producer, ceases to have that effect as soon as it extends to all commodities; because, when all things have fallen, nothing has really fallen, except nominally; and, even computed in money, the expenses of every producer have diminished as much as his returns. Unless, indeed, labor be the one commodity which has not fallen in money price, when all other things have: if so, what has really taken place is a rise of wages; and it is that, and not the fall of prices, which has lowered the profits of capital. There is another thing which escaped the notice of Adam Smith; that the supposed universal fall of prices, through increased competition of capitals, is a thing which can not take place. Prices are not determined by the competition of the sellers only, but also by that of the buyers; by demand as well as supply. The demand which affects money prices consists of all the money in the hands of the community destined to be laid out in commodities; and, as long as the proportion of this to the commodities is not diminished, there is no fall of general prices. Now, howsoever capital may increase, and give rise to an increased production of commodities, a full share of the capital will be drawn to the business of producing or importing money, and the quantity of money will be augmented in an equal ratio with the quantity of commodities. For, if this were not the case, and if money, therefore, were, as the theory supposes, perpetually acquiring increased purchasing power, those who produced or imported it would obtain constantly increasing profits; and this could not happen without attracting labor and capital to that occupation from other employments. If a general fall of prices and increased value of money were really to occur, it could only be as a consequence of increased cost of production, from the gradual exhaustion of the mines.

It is not tenable, therefore, in theory, that the increase of capital produces, or tends to produce, a general decline of money prices. Neither is it true that any general decline of prices, as capital increased, has manifested itself in fact. The only things observed to fall in price with the progress of society are those in which there have been improvements in production, greater than have taken place in the production of the precious metals; as, for example, all spun and woven fabrics. Other things, again, instead of falling, have risen in price, because their cost of production, compared with that of gold and silver, has increased. Among these are all kinds of food, comparison being made with a much earlier period of history. The doctrine, therefore, that competition of capital lowers profits by lowering prices, is incorrect in fact, as well as unsound in principle.

Mr. Wakefield, in his Commentary on Adam Smith, and his important writings on Colonization, takes a much clearer view of the subject, and arrives, through a substantially correct series of deductions, at practical conclusions which appear to me just and important. Mr. Wakefield's explanation of the fall of profits is briefly this: Production is limited not solely by the quantity of capital and of labor, but also by the extent of the “field of employment.” The field of employment for capital is twofold: the land of the country, and the capacity of foreign markets to take its manufactured commodities. On a limited extent of land, only a limited quantity of capital can find employment at a profit. As the quantity of capital approaches this limit, profit falls; when the limit is attained, profit is annihilated, and can only be restored through an extension of the field of employment, either by the acquisition of fertile land, or by opening new markets in foreign countries, from which food and materials can be purchased with the products of domestic capital.[300]
