Goods whose cost of reproduction,[641] that is, the highest necessary cost of reproduction is the same, have uniformly the same value in exchange. Every deviation from this level immediately sets forces in motion which endeavor to restore the level, just as the water of the sea seeks its level, notwithstanding the mountains and abysses which the winds bring forth from its bosom.[642][643]
Section CVIII.
Effect Of A Rise Of Price Much Above Cost.
If the market price rises high above the cost of production, producers make a profit greater than the average profit made in the country. This induces them, by the appropriation of new land and the employment of new labor and capital, to increase their business. Other parties also engage in this profitable department of trade. This competition not only makes the means of production dearer, but must eventually, by increasing the demand, reduce the price of the product to the ordinary level of profit, that is to an equilibrium with other commodities.[644] Hence, in the beginning, every diminution of [pg 321] the cost of production[645] turns to the advantage of the producer; but afterwards and permanently to that of the consumers: an economic law exceedingly beneficent in its operations, and not unlike the action of positive legislation in the matter of patents. There is no greater stimulus to the making of improvements than the certainty of reward to the person who first introduces one. The moment, however, that the improvement is imitated by all producers, the advantage gained by it becomes the common good of the whole nation.[646] These are, as J. B. Say says, conquests made over the gratuitous productive force of nature. As a consequence, the value in use of a people's resources increases; generally, also, their value in exchange, in so far as the production of the now cheaper goods increases in a degree greater than their cost of production has diminished.[647]
As to the alternative so frequently discussed, whether it is preferable to make a large percentage of profit on the sale of a small quantity of goods, or a small percentage on a large quantity, we find that, in the lower stages of civilization, the [pg 322] former is preferred, and the latter in the higher.[648] And, indeed, the latter is not only more humane, but, in the long run, it is more profitable to the person who adopts it as his rule in business. In the case of commodities, he now runs but little risk from a change of fashion, because the fashions of the masses change much less rapidly than those of the upper circles of society. In the case of indispensable goods, on the other hand, he may now calculate with more certainty on the increase of population, and, therefore, on a future market for his wares. Competition, which in former times, devoted all its efforts to bringing about the exclusion, by law, of all rivals, is now engaged, principally, in devising means of surpassing them by superiority of workmanship, and in thus increasing the power of the real sources of a nation's wealth.
Section CIX.
Effect Of A Decline Of Price Below Cost.
If the market price sinks below the cost of production, the producer naturally suffers a loss, and diminishes his stock as soon as possible. That whole establishments engaged in industry should forsake a branch of it which is suffering from depression and enter a flourishing one, must ever remain a rare exception.[649] But the discouraged manufacturer may delay renewing his stock on hand,[650] replacing his machinery by new machinery; he may dismiss some of his workmen and diminish the number of days during which the others shall work. Moreover, most industries are operated by means of borrowed capital, capital which must therefore, be returned to the lender. Under certain circumstances, however, the industry may be continued for some time, even at a real loss,[651] so long as the loss of interest etc., which would follow the entire suspension of the work, exceeds the loss produced by the lowering [pg 324] of price, but hardly any longer. If the supply of the commodity the price of which has fallen has been diminished, the subsequent result depends on the causes which, in the first place, brought about the fall in price. If the diminution in price was caused solely by a too great supply, when this superabundant supply is gotten rid of, the price will rise again.[652] If it were produced by a decrease in the value in use of the commodity, the diminution of the supply can restore the former state of things only in so far as at least a part of the purchasers ascribe to the commodity the same value in use as before.[653] Lastly, if the lowering of the price came from a decrease in the number of buyers, or from a decrease in their ability to purchase, the former price will be restored when production has been adapted to a correspondingly smaller circle of consumers.[654] This last is true especially when the price, without having suffered any absolute change, has become relatively too low, on account of an increase in the cost of production.[655]
