ference in the practical result. It still appears, that the countries which carry on their foreign trade on the most advantageous terms, are those whose commodities are most in demand by foreign countries, and which have themselves the least demand for foreign commodities. From which, among other consequences, it follows, that the richest countries, cateris paribus, gain the least by a given amount of foreign commerce : since, having a greater demand for commodities generally, they are likely to have a greater demand for foreign commodities, and thus modify the terms of interchange to their own disadvantage. Their aggregate gains by foreign trade, doubtless, are generally greater than those of poorer countries, since they carry on a greater amount of such trade, and gain the benefit of cheapness on a larger consumption: but their gain is less on each individual article consumed.
§ 9. We now pass to another essential part of the theory of the subject. There are two senses in which a country obtains commodities cheaper by foreign trade; in the sense of Value, and in the sense of Cost. It gets them cheaper in the first sense, by their falling in value relatively to other things: the same quantity of them exchanging, in the country, for a smaller quantity than before of the other produce of the country. To revert to our original figures; in England, all consumers of linen obtained, after the trade was opened, 17 or some greater number of yards for the same quantity of all other things for which they before obtained only 15. The degree of cheapness, in this sense of the term, depends on the laws of International Demand, so copiously illustrated in the preceding sections. But in the other sense, that of Cost, a country gets a commodity cheaper, when it obtains a greater quantity of the commodity with the same expenditure of labour and capital. In this sense of the term, cheapness in a great measure depends upon a cause of a different nature: a country gets its imports cheaper, in proportion to the general productive
ness of its domestic industry; to the general efficiency of its labour. The labour of one country may be, as a whole, much more efficient than that of another: all or most of the commodities capable of being produced in both, may be produced in one at less absolute cost than in the other; which, as we have seen, will not necessarily prevent the two countries from exchanging commodities. The things which the more favoured country will import from others, are of course those in which it is least superior; but by importing them it acquires, even in those commodities, the same advantage which it possesses in the articles it gives in exchange for them. Thus the countries which obtain their own productions at least cost, also get their imports at least cost. This will be made still more obvious if we suppose two competing countries. England sends cloth to Germany, and gives 10 yards of it for 17 yards of linen, or for something else which in Germany is the equivalent of those 17 yards. Another country, as for example France, does the same. The one giving 10 yards of cloth for a certain quantity of German commodities, so must the other: if, therefore, in England, these 10 yards are produced by only half as much labour as that by which they are produced in France, the linen or other commodities of Germany will cost to England only half the amount of labour which they will cost to France. England would thus obtain her imports at less cost than France, in the ratio of the greater efficiency of her labour in the production of cloth : which might be taken, in the case supposed, as an approximate estimate of the efficiency of her labour generally; since, France, as well as England, by selecting cloth as her article of export, would have shown that with her also it was the commodity in which labour was relatively the most efficient. It follows, therefore, that every country gets its imports at less cost, in proportion to the general efficiency of its labour. This proposition was first clearly seen and expounded by Mr. Senior,” but only as applicable to the importation of the precious metals. I think it important to point out that the proposition holds equally true of all other imported commodities; and further, that it is only a portion of the truth. For, in the case supposed, the cost to England of the linen which she pays for with ten yards of cloth, does not depend solely upon the cost to herself of ten yards of cloth, but partly also upon how many yards of linen she obtains in exchange for them. What her imports cost to her is a function of two variables; the quantity of her own commodities which she gives for them, and the cost of those commodities. Of these, the last alone depends on the efficiency of her labour: the first depends on the law of international values; that is on the intensity and extensibility of the foreign demand for her commodities, compared with her demand for foreign commodities.
* Three Lectures on the Cost of Obtaining Money.
In the case just now supposed, of a competition between England and France, the state of international values affected both competitors alike, since they were supposed to trade with the same country, and to export and import the same commodities. The difference, therefore, in what their imports cost them, depended solely on the other cause, the unequal efficiency of their labour. They gave the same quantities; the difference could only be in the cost of production. But if England traded to Germany with cloth, and France with iron, the comparative demand in Germany for those two commodities would bear a share in determining the comparative cost, in labour and capital, with which England and France would obtain German products. If iron were more in demand in Germany than cloth, France would recover, through that channel, part of her disadvantage; if less, her disadvantage would be increased. The efficiency, therefore, of a country's labour, is not the only thing which determines even the cost at which that country obtains imported commodities—while it has no share whatever in determining either their exchange value, or, as we shall presently see, their price.
OF MONEY CONSIDERED AS AN IMPORTED COMMODITY.
§ 1. The degree of progress which we have now made in the theory of Foreign Trade, puts it in our power to supply what was previously deficient in our view of the theory of Money; and this, when completed, will in its turn enable us to conclude the subject of Foreign Trade. Money, or the material of which it is composed, is, in Great Britain, and in most other countries, a foreign commodity. Its value and distribution must therefore be regulated, not by the law of value which obtains in adjacent places, but by that which is applicable to imported commodities—the law of International Walues. In the discussion into which we are now about to enter, I shall use the terms Money and the Precious Metals indiscriminately. This may be done without leading to any error; it having been shown that the value of money, when it consists of the precious metals, or of a paper currency convertible into them on demand, is entirely governed by the value of the metals themselves: from which it never permanently differs, except by the expense of coinage when this is paid by the individual and not by the state. Money is brought into a country in two different ways. It is imported (chiefly in the form of bullion) like any other merchandize, as being an advantageous article of commerce. It is also imported in its other character of a medium of exchange, to pay some debt due to the country, either for goods exported or on any other account. There are other ways in which it may be introduced casually; these are the two in which it is received in the ordinary course of business, and which determine its value. The existence of these two distinct modes in which money flows into a country, while other commodities are habitually introduced only in the first of these modes, occasions somewhat more of complexity and obscurity than exists in the case of other commodities, and for this reason only is any special and minute exposition necessary.
§ 2. In so far as the precious metals are imported in the ordinary way of commerce, their value must depend on the same causes, and conform to the same laws, as the value of any other foreign production. It is in this mode chiefly that gold and silver diffuse themselves from the mining countries into all other parts of the commercial world. They are the staple commodities of those countries, or at least are among their great articles of regular export; and are shipped on speculation, in the same manner as other exportable commodities. The quantity, therefore, which a country (say England) will give of its own produce, for a certain quantity of bullion, will depend, if we suppose only two countries and two commodities, upon the demand in England for bullion, compared with the demand in the mining country (which we will call Brazil) for what England has to give. They must exchange in such proportions as will leave no unsatisfied demand on either side, to alter values by its competition. The bullion required by England must exactly pay for the cottons or other English commodities required by Brazil. If, however, we substitute for this simplicity the degree of complication which really exists, the equation of international demand must be established not between the bullion wanted in England and the cottons or broadcloth wanted in Brazil, but between the whole of the imports of England and the whole of her exports. The demand in foreign countries for English products, must be brought into equilibrium with the demand in England for the products of foreign countries; and
