CHAPTER XVII.
OF INTERNATIONAL TRADE.
§ 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 import than to produce them: 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
