The disadvantage of the treaty to the importing country would be this: it would bind her to purchase a commodity, from England for example, at the natural price of that commodity in England, when she might perhaps have bought it at the much lower natural price of some other country. It occasions then a disadvantageous distribution of the general capital, which falls chiefly on the country bound by its treaty to buy in the least productive market; but it gives no advantage to the seller on account of any supposed monopoly, for he is prevented by the competition of his own countrymen from selling his goods above their natural price; at which he would sell them, whether he exported them to France, Spain, or the West Indies, or sold them for home consumption.
In what then does the advantage of the stipulation in the treaty consist? It consists in this: these particular goods could not have been made in England for exportation, but for the privilege which she alone had of serving this particular market; for the competition of that country, where the natural price was lower, would have deprived her of all chance of selling those commodities. This, however, would have been of little importance, if England were quite secure that she could sell to the same amount any other goods which she might fabricate, either in the French market, or with equal advantage in any other. The object which England has in view, is, for example, to buy a quantity of French wines of the value of 5000_l._--she desires then to sell goods somewhere by which she may get 5000_l._ for this purpose. If France gives her a monopoly of the cloth market, she will readily export cloth for this purpose; but if the trade is free, the competition of other countries may prevent the natural price of cloth in England from being sufficiently low to enable her to get 5000_l._ by the sale of cloth, and to obtain the usual profits by such an employment of her stock. The industry of England must be employed then on some other commodity; but there may be none of her productions which, at the existing value of money, she can afford to sell at the natural price of other countries. What is the consequence? The wine drinkers of England are still willing to give 5000_l._ for their wine, and consequently 5000_l._ in money is exported to France for that purpose. By this exportation of money its value is raised in England, and lowered in other countries; and with it the _natural price_ of all commodities produced by British industry is also lowered. The advance in the price of money is the same thing as the decline in the price of commodities. To obtain 5000_l._, British commodities may now be exported; for at their reduced natural price they may now enter into competition with the goods of other countries. More goods are sold, however, at the low prices to obtain the 5000_l._ required, which, when obtained, will not procure the same quantity of wine; because, whilst the diminution of money in England has lowered the natural price of goods there, the increase of money in France has raised the natural price of goods and wine in France. Less wine then will be imported into England, in exchange for its commodities, when the trade is perfectly free, than when she is peculiarly favoured by commercial treaties. The _rate_ of profits however will not have varied; money will have altered in relative value in the two countries, and the advantage gained by France will be the obtaining a greater quantity of English, in exchange for a given quantity of French goods, while the loss sustained by England will consist in obtaining a smaller quantity of French goods in exchange for a given quantity of those of England.
