§ 1. The causes which occasion a commodity to be brought from a distance, instead of being produced, as convenience would seem to dictate, as near as possible to the market where it is to be sold for consumption, are usually conceived in a rather superficial manner. Some things it is physically impossible to produce, except in particular circumstances of heat, soil, water, or atmosphere. But there are many things which, though they could be produced at home without difficulty, and in any quantity, are yet imported from a distance. The explanation which would be popularly given of this would be, that it is cheaper to importlhan to produce theni: .and this is the true reason. But this reason itself requires that a reason be given for it. Of two things produced in the same place, if one is cheaper than the other, the reason is that it can be produced with less labour and capital, or, in a word, at less cost. Is this also the reason as between things produced in different places? Are things never imported but from places where they can be produced with less labour (or less of the other element of cost, time) than in the place to which they are brought? Does the law, that permanent value is proportioned to cost of production, hold good between commodities produced in distant places, as it does between those produced in adjacent places?

We shall find that it does not. A thing may sometimes be sold cheapest, by being produced in some other place than that at which it can be produced with the smallest amount of labour and abstinence. England might import corn from Poland and pay for it in cloth, even though England had a decided advantage over Poland in the production of both the one and the other. England might send cottons to Portugal in exchange for wine, although Portugal might be able to produce cottons with a less amount of labour and capital than England could.

This could not happen between adjacent places. If the north bank of the Thames possessed an advantage over the south bank in the production of shoes, no shoes would be produced on the south side; the shoemakers would remove themselves and their capitals to the north bank, or would have established themselves there originally; for being competitors in the same market with those on the north side, they could not compensate themselves for their disadvantage at the expense of the consumer: the amount of it would fall entirely on their profits; and they would not long content themselves with a smaller profit, when, by simply crossing a river, they could increase it. But between distant places, and especially between different countries, profits may continue different; because persons do not usually remove themselves or their capitals to a distant place without a very strong motive. If capital removed to remote parts of the world as readily, and for as small an inducement, as it moves to another quarter of the same town; if people would transport their manufactories to America or China whenever they could save a small percentage in their expenses by it; profits would be alike (or equivalent) all over the world, and all things would be produced in the places where the same labour and capital would produce them in greatest quantity and of best quality. A tendency

Yt even now, be observed towards such a state of things; capital is becoming more and more cosmopolitan; there is so much greater of manners and institutions than formerly, and so much less alienation of feeling, among the more civilized countries, that population and capital now move from one of those countries to another on much less temptation than heretofore. But there are still extraordinary differences, both of wages and of profits, between different parts of the world. It needs but a small motive to transplant capital, or even persons, from Warwickshire to Yorkshire; but a much greater to make them remove to India, the colonies, or Ireland. To France, Germany, or Switzerland, capital moves perhaps almost as readily as to the colonies; the differences of language and government being scarcely so great a hindrance as climate and distance. To countries still barbarous, or, like Russia or Turkey, only beginning to bs civilized, capital will not migrate, unless under the inducement of a very great extra profit.

Between all distant places therefore in some degree, but especially between different countries (whether under the same supreme government or not), there may exist great inequalities in the return to labour and capital, without causing them to move from one place to the other in such quantity as to level those inequalities. The capital belonging to a country will, to a great extent, remain in the country, even if there be no mode of employing it in which it would not be more productive elsewhere. Yet even a country thus circumstanced might, and probably would, carry on trade with other countries. It would export articles of some sort, even to places which could make them with less labour than itself; because those countries, supposing them to have an advantage over it in all productions, would have a greater advantage in some things than in others, and would find it their interest to import the articles in which their advantage was smallest, that they might employ more of their labour and capital on those in which it was greatest.


§ 2. As I have said elsewhere* after Ricardo (the thinker who has done most towards clearing up this subject)! "it is not a difference in the absolute cost of production, which determines the interchange, but a difference in the comparative cost. It may be to our advantage to procure iron from Sweden in exchange for cottons, even although the mines of England as well as her manufactories should be more productive than those of Sweden; for if we have an advantage of one-half in cottons, and only an advantage of a quarter in iron, andj couIcTsell our cottons to Sweden at the price which Sweden must pay for them if she produced them herself, we should obtain our iron with an advantage of one-half as well as our cottons. We may often, by trading with foreigners, obtain their commodities at a smaller expense of labour and capital than they cost to the foreigners themselves. The bargain is still advantageous to the foreigner, because the commodity which he receives in exchange, though it has cost us less, would have cost him more."

To illustrate the cases in which interchange of commodities will not, and those in which it will, take place between two countries, Mr. [James] Mill, in his Elements of Political Economy^ makes the supposition that Poland has an advantage over England in the production both of cloth and of corn. He first supposecL,t3«i-lSflvaiita.ge

•{• [18(52 \ I at one time believed Mr. Ricardo to have been the sole authorof the doctrine now universally received by political economists, on the nature and measure of the benefit which a country derives from foreign trade. But Colonel Torrens, by the republication of one of his early writings, The Economixh lie.futed, has established at least a joint claim with Mr. Ricardo to the origination of the doctrine, and an exclusive one to its earliest publication.

to be of equal amount in both commodities; the cloth and the corn, each of which required 100 days' labour in Poland, requiring each 150 days' labour in England. "It would follow, that the cloth of 150 days' labour in England, if sent to Poland, would be equal to the cloth of 100 days' labour in Poland; if exchanged for corn, therefore, it would exchange for the corn of only 100 days' labour. But the corn of 100 days' labour in Poland was supposed to be the same quantity with that of 150 days' labour in England. With 150 days' labour in cloth, therefore, England would only get as much corn in Poland, as she could raise with 150 days' labour at home; and she would, in importing it, have the cost of carriage besides. In these circumstances no exchange would take place." In this case the comparative cost of the two articles in England and in Poland were supposed to be the same, though the absolute costs were different; on which supposition we see that there would be no labour saved to either country by confining its industry to one of the two productions and importing the other.

It is otherwise when the comparative, and not merely the absolute costs of the two articles are different in the two countries. "If," continues the same author, "while the cloth produced with 100 days' labour in Poland was produced with 150 days' labour in England, the corn which was produced in Poland with 100 days' labour could not be produced in England with less than 200 days' labour; an adequate motive to exchange would immediately arise. With a quantity of cloth which England produced with 150 days' labour, she would be able to purchase as much corn in Poland as was there produced with 100 days' labour; but the quantity which was there produced with 100 days' labour, would be as great as the quantity produced in England with 200 days' labour." By importing corn, therefore, from Poland, and paying for it with cloth, England would obtain for 150 days' labour what would otherwise cost her 200; being a saving of 50 days' labour on each repetition of the transaction: and not merely a saving to England, but a saving absolutely; for it is not obtained at the expense of Poland, who, with corn that costs her 100 days' labour, has purchased cloth which, if produced at home, would have cost her the same. Poland, therefore, on this supposition, loses nothing; but also she derives no advantage from the trade, the imported cloth costing her as much as if it were made at home. To enable Poland to gain anything by the interchange, something must be abated from the gain of England: the corn produced in Poland by 100 days' labour must be able to purchase from England more cloth than Poland could produce by that amount of labour; more therefore than England could produce by 150 days' labour, England thus obtaining the corn which would have cost her 200 days, at a cost exceeding 150, though short of 200. England therefore no longer gains the whole of the labour which is saved to the two jointly by trading with one another.

§ 3. From this exposition we perceive in what consists the benefit of international exchange, or, in other words, foreign commerce. Setting aside its enabling countries to obtain commodities which they could not themselves produce at all; its advantage consists in a more efficient employment of the productive forces of the world.^ If two countries which trade together attempted, as far as was physically possible, to produce for themselves what they now import from one another, the labour and capital of the two countries would not be so productive, the two together would not obtain from their industry so great a quantity of commodities, as when each employs itself in producing, both for itself and for the other, the things in which its labour is relatively most efficient. ^CThe addition thus made to the produce of the two combined, constitutes the advantage of the trade. It is possible that one of the two countries may be altogether inferior to the other in productive capacities, and that its labour and capital could be employed to greatest advantage by being removed bodily to the other. The labour and capital which have been sunk in rendering Holland habitable, would have produced a much greater return if transported to America or Ireland. The produce of the whole world would be greater, or the labour less, than it is, if everything were produced where there is the greatest absolute facility for its production. But nations do not, at least in modern times, emigrate en masse; and while the labour and capital of a country remain in the country, they are most beneficially employed in producing, for foreign markets as well as for its own, the things in which it lies under the least disadvantage, if there be none in which it possesses an advantage.

§ 4. Before proceeding further, let us contrast this view of the benefits of international commerce with other theories which have prevailed, and which to a certain extent still prevail, on the same subject.

According to the doctrine now stated, the only direct advantage of foreign commerce consists in the imports. A country obtains
