replaced, with the ordinary profit, from the returns, as it was when employed in producing for the foreign market. The only losers (after the temporary inconvenience of the change) would be the consumers of the heretofore imported articles; who would be obliged either to do without them, consuming in lieu of them something which they did not like as well, or to pay a higher price for them than before. There is much misconception in the common notion of what commerce does for a country. When commerce is spoken of as a source of national wealth, the imagination fixes itself upon the large fortunes acquired by merchants, rather than upon the saving of price to consumers. But the gains of merchants, when they enjoy no exclusive privilege, are no greater than the profits obtained by the employment of capital in the country itself. If it be said that the capital now employed | in foreign trade could not find employment in supplying the home market, I might reply, that this is the fallacy of general over-production, discussed in a former chapter: but the thing is in this particular case too evident, to require an appeal to any general theory. We not only see that the capital of the merchant would find employment, but we see what employment. There would be employment created, equal to that which would be taken away. Exportation ceasing, importation to an equal value would cease also, and all that part of the income of the country which had been expended in imported commodities, would be ready to expend itself on the same things produced at home, or on others instead of them. Commerce is virtually a mode of cheapening production; and in all such cases the consumer is the person ultimately benefited; the dealer, in the end, is sure to get his profit, whether the buyer obtains much or little for his money. This is said without prejudice to the effect (already touched upon, and to be hereafter fully discussed) which the cheapening of commodities may have in raising profits; in the case when the commodity cheapened, being one of those consumed by labourers, enters into the cost of labour, by which the rate of profits is determined. § 5. Such, then, is the direct economical advantage of foreign trade. But there are, besides, indirect effects, which must be counted as benefits of a high order. One is, the tendency of every extension of the market to improve the processes of production. A country which produces for a larger market than its own, can introduce a more extended division of labour, can make greater use of machinery, and is more likely to make inventions and improvements in the processes of production. Whatever causes a greater quantity of anything to be produced in the same place, tends to the general increase of the productive powers of the world.* There is another consideration, principally applicable to an early stage of industrial advancement. A people may be in a quiescent, indolent, uncultivated state, with all their tastes either fully satisfied or entirely undeveloped, and they may fail to put forth the whole of their productive energies for want of any sufficient object of desire. The opening of a foreign trade, by making them acquainted with new objects, or tempting them by the easier acquisition of things which they had not previously thought attainable, sometimes works a sort of industrial revolution in a country whose resources were previously undeveloped for want of energy and ambition in the people: inducing those who were satisfied with scanty comforts and little work, to work harder for the gratification of their new tastes, and even to save, and accumulate capital, for the still more complete satisfaction of those tastes at a future time. But the economical advantages of commerce are surpassed in importance by those of its effects, which are intellectual and moral. It is hardly possible to overrate the value, in the present low state of human improvement, of placing human beings in contact with persons dissimilar to themselves, and with modes of thought and action * Vide supra, book i, ch, ix, § 1. unlike those with which they are fami- | tial points of character in which its own type is inferior.

CHAPTER XVIII. OF INTERNATIONAL VALUES. § 1. THE values of commodities produced at the same place, or in places sufficiently adjacent for capital to move freely between them-let us say, for simplicity, of commodities produced in the same country-depend (temporary fluctuations apart) upon their cost of production. But the value of a commodity brought from a distant place, especially from a foreign country, does not depend on its cost of production in the place from whence it comes. On what, then, does it depend? The value of a thing in any place, depends on the cost of its acquisition in that place; which in the case of an imported article, means the cost of production of the thing which is exported to pay for it. form, what it always is in reality, an actual trucking of one commodity against another. As far as we have hitherto proceeded, we have found all the laws of interchange to be essentially the same, whether money is used or not; money never governing, but always obeying, those general laws. If, then, England imports wine from Spain, giving for every pipe of wine a bale of cloth, the exchange value of a pipe of wine in England will not depend upon what the production of the wine may have cost in Spain, but upon what the production of the cloth has cost in England. Though the wine may have cost in Spain the equivalent of only ten days labour, yet, if the cloth costs in Since all trade is in reality barter, England twenty days labour, the wine, money being a mere instrument for when brought to England, will exexchanging things against one another, change for the produce of twenty days we will, for simplicity, begin by sup- English labour, plus the cost of carposing the international trade to be inriage; including the usual profit on the importer's capital during the time it is locked up, and withheld from other employment. The value, then, in any country, of a foreign commodity, depends on the quantity of home produce which must be given to the foreign country in exchange for it. In other words, the values of foreign commodities depend on the terms of international exchange. What, then, do these depend upon? What is it, which, in the case supposed, causes a pipe of wine from Spain to be exchanged with England for exactly that quantity of cloth? We have seen that it is not their cost of production. If the cloth and the wine were both made in Spain, they would exchange at their cost of production in Spain; if they were both made in England, they would exchange at their cost of production in England: but all the cloth being made in England, and all the wine in Spain, they are in circumstances to which we have already determined that the law of cost of production is not applicable. We must accordingly, as we have done before in a similar embarrassment, fall back upon an antecedent law, that of supply and demand: and in this we shall again find the solution of our difficulty. I have discussed this question in a separate Essay, already once referred to; and a quotation of part of the exposition then given, will be the best introduction to my present view of the subject. I must give notice that we are now in the region of the most complicated questions which political economy affords; that the subject is one which cannot possibly be made elementary; and that a more continuous effort of attention than has yet been required, will be necessary to follow the series of deductions. The thread, however, which we are about to take in hand, is in itself very simple and manageable; the only difficulty is in following it through the windings and entanglements of complex international transactions. § 2. "When the trade is established between the two countries, the two commodities will exchange for P.E. each other at the same rate of interchange in both countries-bating the cost of carriage, of which, for the present, it will be more convenient to omit the consideration. Supposing, therefore, for the sake of argument, that the carriage of the commodities from one country to the other could be effected without labour and without cost, no sooner would the trade be opened than the value of the two commodities, cstimated in each other, would come to a level in both countries. Suppose that 10 yards of broadcloth cost in England as much labour, as 15 yards of linen, and in Germany as much as 20." In common with most of my predecessors, I find it ad visable, in these intricate investigations, to give distinctness and fixity to the conception by numerical examples. These examples must sometimes, as in the present case, be purely supposititious. I should have preferred real ones; but all that is essential is, that the numbers should be such as admit of being easily followed through the subsequent combinations into which they enter. This supposition then being made, it would be the interest of England to import linen from Germany, and of Germany to import cloth from England. "When each country produced both commodities for itself, 10 yards of cloth exchanged for 15 yards of linen in England, and for 20 in Germany. They will now exchange for the same number of yards of linen in both. For what number? If for 15 yards, England will be just as she was, and Germany will gain all. If for 20 yards, Germany will be as before, and England will derive the whole of the benefit. If for any number intermediate between 15 and 20, the advantage will be shared between the two countries. If, for example, 10 yards of cloth exchange for 18 of linen, England will gain an advantage of 3 yards on every 15, Germany will save 2 out of every 20. The problem is, what are the causes which determine the proportion in which the cloth of England and the linen of Germany will exchange for each other. A A in the ratio of 17 yards of linen for 10 yards of cloth. "As exchange value, in this case as in every other, is proverbially fluctuating, it does not matter what we suppose it to be when we begin: we shall soon see whether there be any fixed point about which it oscillates, which it has a tendency always to approach to, and to remain at. Let us suppose, then, that by the effect of what Adam Smith calls the higgling of the market, 10 yards of cloth, in both countries, exchange for 17 yards of linen. "The demand for a commodity, that is, the quantity of it which can find a purchaser, varies, as we have before remarked, according to the price. In Germany the price of 10 yards of cloth is now 17 yards of linen, or whatever quantity of money is equivalent in Germany to 17 yards of linen. Now, that being the price, there is some particular number of yards of cloth, which will be in demand, or will find purchasers, at that price. There is some given quantity of cloth, more than which could not be disposed of at that price; less than which, at that price, would not fully satisfy the demand. Let us suppose this quantity to be 1000 times 10 yards. "Let us now turn our attention to England. There, the price of 17 yards of linen is 10 yards of cloth, or whatever quantity of money is equivalent in England to 10 yards of cloth. There is some particular number of yards of linen which, at that price, will exactly satisfy the demand, and no more. Let us suppose that this number is 1000 times 17 yards. "As 17 yards of linen are to 10 yards of cloth, so are 1000 times 17 yards to 1000 times 10 yards. At the existing exchange value, the linen which England requires will exactly pay for the quantity of cloth which, on the same terms of interchange, Germany requires. The demand on each side is precisely sufficient to carry off the supply on the other. The conditions required by the principle of demand and supply are fulfilled, and the two commodities will continue to be interchanged, as we supposed them to be, no "But our suppositions might have been different. Suppose that, at the assumed rate of interchange, England had been disposed to consume greater quantity of linen than 800 times 17 yards: it is evident that, at the rate supposed, this would not have sufficed to pay for the 1000 times 10 yards of cloth which we have supposed Germany to require at the assumed value. Germany would be able to procure no more than 800 times 10 yards at that price. To procure the remaining 200, which she would have no means of doing but by bidding higher for them, she would offer more than 17 yards of linen in exchange for 10 yards of cloth: let us suppose her to offer 18. At this price, perhaps, England would be inclined to purchase a greater quantity of linen. She would consume, possibly, at that price, 900 times 18 yards. On the other hand, cloth having risen in price, the demand of Germany for it would probably have diminished. If, instead of 1000 times 10 yards, she is now contented with 900 times 10 yards, these will exactly pay for the 900 times 18 yards of linen which England is willing to take at the altered price: the demand on each side will again exactly suffice to take off the corresponding supply; and 10 yards for 18 will be the rate at which, in both countries, cloth will exchange for linen. "The converse of all this would have happened, if, instead of 800 times 17 yards, we had supposed that England, at the rate of 10 for 17, would have taken 1200 times 17 yards of linen. In this case, it is England whose demand is not fully supplied; it is England who, by bidding for more linen, will alter the rate of interchange to her own disadvantage; and 10 yards of cloth will fall, in both countries, below the value of 17 yards of linen. By this fall of cloth, or what is the same thing, this rise of linen, the demand of Germany for cloth will increase, and the demand of England for linen will diminish, till the rate of interchange has so adjusted itself that the cloth and the linen will exactly pay for one another; and when once this point is attained, values will remain without further alteration. "It may be considered, therefore, as established, that when two countries trade together in two commodities, the exchange value of these commodities relatively to each other will adjust itself to the inclinations and circumstances of the consumers on both sides, in such manner that the quantities required by each country, of the articles which it imports from its neighbour, shall be exactly sufficient to pay for one another. As the inclinations and circumstances of consumers cannot be reduced to any rule, so neither can the proportions in which the two commodities will be interchanged. We know that the limits within which the variation is confined, are the ratio between their costs of production in the one country, and the ratio between their costs of production in the other. Ten yards of cloth cannot exchange for more than 20 yards of linen, nor for less than 15. But they may exchange for any intermediate number. The ratios, therefore, in which the advantage of the trade may be divided between the two nations, are various. The circumstances on which the proportionate share of each country more remotely depends, admit only of a very general indication. "It is even possible to conceive an extreme case, in which the whole of the advantage resulting from the interchange would be reaped by one party, the other country gaining nothing at all. There is no absurdity in the hypothesis that, of some given commodity, a certain quantity is all that is wanted at any price; and that, when that quantity is obtained, no fall in the exchange value would induce other consumers to come forward, or those who are already supplied, to take more. Let us suppose that this is the case in Germany with cloth. Before her trade with England commenced, when 10 yards of cloth cost her as much labour as 20 yards of linen, she nevertheless consumed as much cloth as she wanted under any circumstances, and, if she could obtain it at the rate of 10 yards of cloth for 15 of linen, she would not consume more. Let this fixed quantity be 1000 times 10 yards. At the rate, however, of 10 for 20, England would want more linen than would be equivalent to this quantity of cloth. She would, consequently, offer a higher value for linen; or, what is the same thing, she would offer her cloth at a cheaper rate. But, as by no lowering of the value could she prevail on Germany to take a greater quantity of cloth, there would be no limit to the rise of linen or fall of cloth, until the demand of England for linen was reduced by the rise of its value, to the quantity which 1000 times 10 yards of cloth would purchase. It might be, that to produce this diminution of the demand a less fall would not suffice than that which would make 10 yards of cloth exchange for 15 of linen. Germany would then gain the whole of the advantage, and England would be exactly as she was before the trade commenced. It would be for the interest, however, of Germany herself to keep her linen a little below the value at which it could be produced in England, in order to keep herself from being supplanted by the home producer. England, therefore, would always benefit in some degree by the existence of the trade, though it might be a very trifling one." In this statement, I conceive, is contained the first elementary principle of International Values. I have, as is indispensable in such abstract and hypothetical cases, supposed the circumstances to be much less complex than they really are: in the first place by suppressing the cost of carriage: next, by supposing that there are only two countries trading together; and lastly, that they trade only in two commodities. To render the exposition of the principle complete, it is necessary to restore the various circumstances, thus temporarily left out to simplify the argument. Those who are accustomed to any kind of scientific investigation will probably see, without formal proof, that the introduction of these circumstances cannot alter the theory of the |
