1.nlike those with which they are famiiiar. Commerce is now, what war once was, the principal source of this contact. Commercial adventurers from more advanced countries have generally been the first civilizers of barbarians. And commerce is the purpose of the far greater part of the communication which takes place between civilized nations. Such communication has always been, and is peculiarly in the present age, one of the primary sources of progress. To human beings, who, as hitherto educated, can scarcely cultivate even a good quality without running it into a fault, it is indispensable to be perpetually comparing their own notions and customs with the experience and example of persons in dif. ferent circumstances from themselves: and there is no nation which does not need to borrow from others, not merely particular arts or practices, but essen

tial points of character in which its own type is inferior. Finally, commerce first taught nations to see with good-will the wealth and prosperity of one another. Before, the patriot, unless sufficiently advanced in culture to feel the world his country, wished all countries weak, poor, and ill-governed, but his own: he now sees in their wealth and progress a direct source of wealth and progress to his own country. It is commerce which is rapidly rendering war obsolete, by strengthening and multiplying the personal interests which are in natural opposition to it. And it may be said without exaggeration, that the great extent and rapid increase of international trade, in being the principal guarantee of the peace of the world, is the great permanent security for the uninterrupted progress of the ideas, the institutions, and the cha. racter of the human race.



§ 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.

Since all trade is in reality barter, money being a mere instrument for exchanging things against one another, we will, for simplicity, begin by, supposing the international trade to be in

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 produc. tion 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 England twenty days labour, the wine, when brought to England, will exchange for the produce of twenty days English labour, plus the cost of car. riage; including the usual profit on the

in, porter'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 2 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 suppl 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 esta

blished between the two countries, the

two commodities will exchange for F.E.

each other at the same rate of inter. change 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, estimated in each other, would come to a level in both countries. “Suppose that 10 yards cf 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 advisable, 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, German 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 i. and the linen of Germany will exchange for

each other, A A

“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 .# 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, them, 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 o 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,

in the ratio of 17 yards of linen for 10 yards of cloth. “But our suppositions, might have been different. Suppose that, at the assumed rate of interchange, England had been disposed to consume no 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 ards 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 interchango 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 tonsumed as much cloth as she wanted

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 equi. valent 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. Fo as is indispensable in such abstract and hypothetical cases, supposed the circum. stances 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 circum

under any circumstances, and, if she

stances cannot alter the theory of the subject. Trade among any number of countries, and in any number of commodities, must take place on the same essential principles as trade between two countries and in two commodities. Introducing a greater number of agents recisely similar, cannot change the }. of their action, no more than putting additional weights into the two scales of a balance alters the law of gravitation. It alters nothing but the numerical results. For more complete satisfaction, however, we will enter into the complex cases with the same particularity with which we have stated the simpler one.

§ 3. First, let us introduce the element of cost of carriage. The chief difference will then be, that the cloth and the linen will no longer exchange for each other at precisely the sanie rate in both countries. Linen, having to be carried to England, will be dearer there by its cost of carriage; and cloth will be dearer in Germany by the cost of carrying it from England. Linen, estimated in cloth, will be dearer in England than in Germany, by the cost of carriage of both articles. and so will cloth in Germany, estimated in linen. Suppose that the cost of carriage of each is equivalent to one yard of linen; and suppose that, if they could have been carried without cost, the terms of interchange would have been 10 yards of cloth for 17 of linen. It may seem at first that each country will pay its own cost of carriage; that is, the carriage of the article it imports; that in Germany 10 yards of cloth will exchange for 18 of linen, namely, the original 17, and 1 to cover the cost of garriage of the cloth; while in England, 10 yards of cloth will only purchase 16 of linen, 1 yard being deducted for the cost of carriage of the linen. This, however, cannot be af. firmed with certainty; it will only be true, if the linen which the English consumers would take at the price of 10 for 16, exactly pays for the cloth which the German consumers would take at 10 for 18. The values, whatever they are, must establish this equilibrium. No absolute rule, therefore,

can be laid down for the division of the cost, no more than for the division of the advantage: and it does not follow that in whatever ratio the one is divided, the other will be divided in the same. It is impossible to say, if the cost of carriage could be annihilated, whether the producing or the importing country would be most benefited. This would depend on the play of international demand. Cost of carriage has one effect more. But for it, every commodity would (if trade be supposed free) be either regularly imported or regularly exported. A country would make nothing for itself which it did not also make for other countries. But in consequence of cost of carriage there are man things, especially bulky articles, j. every, or almost every country produces within itself. After exporting the things in which it can employ itself most advantageously, and importing those in which it is under the greatest disadvantage, there are many lying between, of which the relative cost of production in that and in other countries differs so little, that the cost of carriage would absorb more than the whole saving in cost of production which would be obtained by importing one and exporting another. This is the case with numerous commodities of common consumption; including the coarser qualities of many articles of food and manufacture, of which the finer kinds are the subject of extensive international traffic.

§ 4. Let us now introduce a greater number of commodities than the two we have hitherto supposed. Let cloth and linen, however, be still the articles of which the comparative cost of production in England and in Germany differs the most; so that if they were confined to two commodities, these would be the two which it would be most their interest to exchange. We will now again omit cost of carriage, which, having been shown not to affect the essentials of the question, does but embarrass unnecessarily the statement of it. Let us suppose, then, that the demand of England for linen is either
