sary for the elucidation of principles. I now therefore proceed to the only part of the general theory of exchange which has not yet been touched upon,
that of International Exchanges, or to speak more generally, exchanges between distant places.
O* INTERNATIONAL TKADB.
§ 1. The causes which occasion a tommodity 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 import than to produce them: and tins 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, tho 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 tho 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 tho 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; tho shoemakers would remove themselves and their capitals to the north bank, or would have established themselves thero 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 may, even now, be observed towards such a state of things; capital is becoming more and more cosmopolitan; there is so much greater similarity of manners and institutions than formerly, and so much less alienation of feeling, among the more civilized countries, that both population and capital now tuove 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 Prance, Germany, or Switzerland, capital moves perhaps almost as readily as to the colonies; the differences of language and government being scarcely Bo great a hindrance as climate and distance. To countries still barbarous, or, like Russia or Turkey, only beginning to be 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 ono 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 tome things than in others, and would find it their interest to import the articles in which their advantage was
smallest, that thty might employ more of their labour and capital on those in which it was greatest.
§ 2. As I have said elsewhere* after Bicardo (the thinker who has done most towards clearingup 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 wo have an advantage of one-half in cottons, and only an advantage of a quarter in iron, and could sell 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. 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. lie first supposes the advantage to be of equal amount in both commodities: the cloth and the corn, each of which required 100 days labour in Poland, requiring
* Essay* on tome Unsettled Question* of Political Economy, Essay 1.
t I at one time believed Mr. Rlcardo to have been the sole author of 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 Economists Befitted, has established at least a joint claim with Mr. Ricardo to the origination of the doctrine, and an exclusive ona to its earliest publication.

eftch 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 carnage besides. In these circumstances no exchange would take place." In this case the comparative costs of the two articles in England and in Poland were supposed to be the same, though the absolute costs were differ, ent; on which supposition we see that there would be no labour saved to cither 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 tiuthor, " 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 hava 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 tho interchange, something must be abated from the gain of England: tho 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 tho 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 o* international exchange, or in other words, foreign commerce. Setting aside its enabling countries to obtain commodities which they could not themselves produco at all; its advantage consists in a more efficient employment of the productive forces ot 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. The 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 cr Ireland. The produce of the whole world would he 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 things which it either could not have produced at all, or which it must have produced at a greater expense of capital and labour than the cost of the things which it exports to pay for them. It thus obtains a more ample supply of the commodities it wants, for the same labour and capital; or the same supply, for less labour and capital, leaving the surplus disposable to produce other things. The vulgar theory disregards this benefit, and deems the advantage of commerce to reside in the exports: as if not what a country obtains, but what it parts with, by its foreign trade, was supposed to constitute the gain to it. An extended market for its produce—an abundant consumption for its goods—a vent for its surplus—are the phrases by which it has been customary to designate the uses and recommendations of commerce with foreign countries. This notion is intelligible, when we consider that the authors and leaders of opinion on mercantile questions have always hitherto been the selling class. It is in truth a surviving relic of the Mercantile Theory, according to which, money being the only wealth, selling, or in
other words, exchanging goods for money, was (to countries without mines of their own) the only way of growing rich — and importation of goods, that is to say, parting with money, was so much subtracted from the benefit.
The notion that money alone is wealth, has been long defunct, but i/ has left many of its progeny oehind it; and even its destroyer, Adam Smith, retained some opinions which it is impossible to trace to any other origin. Adam Smith's theory of the benefit of foreign trade, was thatit afforded an outlet for tho surplus produce of a country, and enabled a portion of the capital of tho country to replace itself with a profit. These expressions suggest ideas inconsistent with a clear conception of the phenomena. The expression, surplus produce, seems to imply that a country is under some kind of necessity of producing the corn or cloth which it exports; so that the portion which it docs not itself consume, if not wanted and consumed elsewhere, would either be produced in sheer waste, or if it were not produced, tho corresponding portion of capital would remain idle, and the mass of productions in the country would he diminished by so much. Either of these suppositions would be entirely erroneous. The country produces an exportable article in excess of its own wants, from no inherent necessity, but as the cheapest mode of supplying itself with other things. If prevented from exporting this surplus, it would cease to produce it, and would no longer import anything, being unable to give an equivalent; but the labour and capital which had been employed in producing with a view to exportation, would find employment in producing those desirable objects which were previously brought from abroad: or, if some of them could not be produced, in producing substitutes for them. These articles would of course be produced at a greater cost than that of the things with which they had previously been purchased from foreign countries. But the value and price of the articles would rise in proportion; and the capital would just as much b*
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 he the consumers of the heretofore imported articles; who would he ohligcd 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 beforo.
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 he 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 ohtains 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 caso when tho commodity cheapened, being one of those consumed by labourers, enters
into the cost of labour, by which thg rate of profits h 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 tho 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 mako inventions and improvements in the processes of production. Whatever causes a greater quantity of anything to he 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 tho 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 whoso resources were previously undeveloped for want of energy and ambition in the people: inducing those who were satisfied with scanty comforts and littlo work, to work harder for tho gratification of their new tastes, and even to save, and accumulate capital, for tho 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 aaiiaQ
