demand for cloth to the limit of a million, or else tempt England to part with some of the cloth she previously consumed at home.
Let us next suppose that the proportionality of demand to cheapness, instead of holding good in one country but not in the other, does not hold good in either country, and that the deviation is of the same kind in both; that, for instance, neither of the two increases its demand in a degree equivalent to the increase of cheapness. On this supposition, at the rate of one million cloth for 1,600,000 linen, England will not want so much as 1,000,000 linen, nor Germany so much as a million cloth: and if they fall short of that amount in exactly the same degree: if England only wants linen to the amount of nine-tenths of 1,600,000 (1,440,000), and Germany only nine hundred thousand of cloth, the interchange will continue to take place at the same rate. And so if England wants a tenth more than 1,600,000, and Germany a tenth more than a million. This coincidence (which, it is to be observed, supposes demand to extend cheapness in a corresponding, but not in an equal degree[1]) evidently could not exist unless by mere accident: and in any other case, the equation of international demand would require a different adjustment of international values.
The only general law, then, which can be laid down, is this. The values at which a country exchanges its produce with foreign countries depend on two things: first, on the amount and extensibility of their demand for its commodities, compared with its demand for theirs; and secondly, on the capital which it has to spare, from the production of domestic commodities for its own consumption. The more the foreign demand for its commodities exceeds its demand for foreign
- ↑ The increase of demand from 800,000 to 900,000, and that from a million to 1,440,000, are neither equal in themselves, nor bear an equal proportion to the increase of cheapness. Germany's demand for cloth has increased one-eighth, while the cheapness is increased one-fourth. England's demand for linen is increased 44 per cent, while the cheapness is increased 60 per cent.
