140 article, but which they may likewise expend in other articles, and among others, in cloth or other imported commodities. This would be an additional element in the international demand, and would modify more or less the terms of interchange.

Of the three possible varieties in the influence of cheapness on demand, which is the more probable—that the demand would be increased more than the cheapness, as much as the cheapness, or less than the cheapness? This depends on the nature of the particular commodity, and on the tastes of purchasers. When the commodity is one in general request, and the fall of its price brings it within reach of a much larger class of incomes than before, the demand is often increased in a greater ratio than the fall of price, and a larger sum of money is on the whole expended in the article. Such was the case with coffee, when its price was lowered by successive reductions of taxation; and such would probably be the case with sugar, wine, and a large class of commodities which, though not necessaries, are largely consumed, and in which many consumers indulge when the articles are cheap and economize when they are dear. But it more frequently happens that when a commodity falls in price, less money is spent in it than before: a greater quantity is consumed, but not so great a value. The consumer who saves money by the cheapness of the article, will be likely to expend part of the saving in increasing his consumption of other things: and unless the low price attracts a large class of new purchasers who were either not consumers of the article at all, or only in small quantity and occasionally, a less aggregate sum will be expended on it. Speaking generally, therefore, the third of our three cases is the most probable: and an improvement in an exportable article is likely to be as beneficial (if not more beneficial) to foreign countries, as to the country where the article is produced.
