linen in Germany, (and consequently in England). Germany, therefore, by the annihilation of cost of carriage, would save in price more than the cost of carriage of the cloth; England would save less in price than the cost of carriage of the linen. But if by the miraculous annihilation of cost of carriage, England would not save the whole of the carriage of her imports, it follows that England did not previously pay the whole of that cost of carriage.
Thus, the division of the cost of trade, and the division of the advantage of trade, are governed by precisely the same principles; and the only general proposition which can be affirmed respecting the cost is, that it is pro tanto a deduction from the advantage. It cannot even be maintained that the cost is shared in the same proportion as the advantage is; because the increase of the demand for a commodity as its price falls, is not governed by any fixed law. Suppose, for instance, that the advantage happened to be divided equally: this must be because the greater cheapness arising from the establishment of the trade, either did not affect the demand at all, or affected it in an equal proportion on both sides. Now, because such is the effect of the degree of increased cheapness resulting from importation burthened with cost of carriage, it would not follow that the still greater degree of cheapness, produced by the additional saving of the cost of carriage itself, would also affect the demand of both countries in precisely an equal degree. But we cannot be said to bear an expense, which, if saved, would be saved to somebody else, and not to us. Two countries may have equal shares of the clear benefit of the trade, while, if the cost of carriage were saved, they would divide that saving unequally. If so, they divide the gross gain in one unequal ratio, the cost in another unequal ratio, though their shares of the cost being deducted from their shares of the gain leave equal remainders.
4. The question naturally suggests itself, whether any country, by its own legislative policy, can engross to itself a larger share of the benefits of foreign commerce, than would fall to it in the natural or spontaneous course of trade.
The answer is, it can. By taxing exports, for instance, we may, under certain circumstances, produce a division of the advantage of the trade more favourable to ourselves. In some cases, we may draw into our coffers, at the expense of foreigners, not only the whole tax, but more than the tax: in other cases, we should gain exactly the tax, – in others, less than the tax. In this last case, a part of the tax is borne by ourselves: possibly the whole, possibly even, as we shall show, more than the whole.
Suppose that England taxes her export of cloth: the tax not being supposed high enough to induce Germany to produce cloth for herself. The price at which cloth can be sold in Germany is augmented by the tax. This will probably diminish the quantity consumed. It may diminish it so much, that even at the increased price, there will not be required so great a money value as before. It may diminish it in such a ratio, that the money value of the quantity consumed will be exactly the same as before. Or it may not diminish it at all, or so little, that, in consequence of the higher price, a greater money value will be purchased than before. In this last case, England will gain, at the expense of Germany, not only the whole amount of the duty, but more. For the money value of her exports to Germany being increased, while her imports remain the same, money will flow into England from Germany. The price of cloth will rise in England, and consequently in Germany; but the price of linen will fall in Germany, and consequently in England, We shall export less cloth, and import more linen, till the equilibrium is restored. It thus appears, what is at first sight somewhat remarkable, that, by taxing her exports, England would, under some conceivable circumstances, not only gain from her foreign customers the whole amount of the tax, but would also get her imports cheaper. She would get them cheaper in two ways, – for she would obtain them for less money, and would have more money to purchase them with. Germany, on the other hand, would suffer doubly: she would have to pay for her cloth a price increased not only by the duty, but by the influx of money into England, while the same change in the distribution of the circulating medium would leave her less money to purchase it with.
This, however, is only one of three possible cases. If, after the imposition of the duty, Germany requires so diminished a quantity of cloth, that its total money value is exactly the same as before, the balance of trade will be undisturbed; England will gain the duty, Germany will lose it, and nothing more. If, again, the imposition of the duty occasions such a falling off in the demand, that Germany requires a less pecuniary value than before, our exports will no longer pay for our imports, money must pass from England into Germany, and Germany's share of the advantage of the trade will be increased. By the change in the distribution of money, cloth will fall in England; and therefore it will, of course, fall in Germany. Thus Germany will not pay the whole of the tax. From the same cause, linen will rise in Germany, and consequently in England. When this alteration of prices has so adjusted the demand, that the cloth and the linen again pay for one another, the result is, that Germany has paid only a part of the tax, and the remainder of what has been received into our treasury has come indirectly out of the pockets of our own consumers of linen, who pay a higher price for that imported commodity, in consequence of the tax on our exports, which at the same time they, in consequence of the efflux of money and consequent fall of prices, have smaller money incomes wherewith to pay for the linen at that advanced price.
It is not an impossible supposition that, by taxing our exports, we might not only gain nothing from the foreigner, the tax being paid out of our own pockets, but might even compel our own people to pay a second tax to the foreigner. Suppose, as before, that the demand of Germany for cloth falls off so much on the imposition of the duty, that she requires a smaller money value than before, but that the case is so different with linen in England, that when the price rises the demand either does not fall off at all, or so little that the money value required is greater than before. The first effect of laying on the duty is, as before, that the cloth exported will no longer pay for the linen imported. Money will, therefore, flow out of England into Germany. One effect is to raise the price of linen in Germany, and, consequently, in England. But this, by the supposition, instead of stopping the efflux of money, only makes it greater, because the higher the price, the greater the money value of the linen consumed. The balance, therefore, can only be restored by the other effect, which is going on at the same time, namely, the fall of cloth in the English, and, consequently, in the German market. Even when cloth has fallen so low that its price with the duty is only equal to what its price without the duty was at first, it is not a necessary consequence that the fall will stop; for the same amount of exportation as before will not now suffice to pay the increased money value of the imports; and although the German consumers have now not only cloth at the old price, but likewise increased money incomes, it is not certain that they will be inclined to employ the increase of their incomes in increasing their purchases of cloth. The price of cloth, therefore, must perhaps fall, to restore the equilibrium, more than the whole amount of the duty; Germany may be enabled to import cloth at a lower price when it is taxed, than when it was untaxed: and this gain she will acquire at the expense of the English consumers of linen, who, in addition, will be the real payers of the whole of what is received at their own custom-house under the name of duties on the export of cloth.
Such are the extremely various effects which may result to ourselves, and to our customers, from the imposition of taxes on our exports 3: and the determining circumstances are of a nature so imperfectly ascertainable, that it must be almost impossible to decide with any certainty, even after the tax has been imposed, whether we have been gainers by it or losers. It is certain, however, that whatever we gain, is lost by somebody else, and there is the expense of the collection besides: if international morality, therefore, were rightly understood and acted upon, such taxes, as being contrary to the universal weal, would not exist. Moreover, the imposition of such a tax frequently will, and always may, expose a country to lose this branch of its trade altogether, or to carry it on with diminished advantage, in consequence of the competition of untaxed exporters from other countries, or of the domestic producers in the country to which it exports. Even on the most selfish principles, therefore, the benefit of such a tax is always extremely precarious.
5. We have had an example of a tax on exports, that is, on foreigners, falling in part on ourselves. We shall, therefore, not be surprised if we find a
We have not deemed it necessary to enter minutely into all the circumstances which might modify the results mentioned in the text. For example, let us revert to the first case, that in which the demand for cloth in Germany is so little affected by the rise of price in consequence of the tax, that the quantity bought exceeds in pecuniary value what it was before. As the German consumers lay out more money in cloth, they have less to lay out in other things; other money prices will fall; among the rest that of linen; and this may so increase the demand for linen in England as to restore the equilibrium of exports and imports without any passage of money. But England's treasury will still gain from Germany the whole of the tax, and the English people will buy their linen cheaper besides. Again, in the opposite case, where the tax so diminishes the demand, that a smaller pecuniary value is required than before. The German consumers have, therefore, more to expend in other things; these, and among the rest linen, will rise; and this may so diminish the demand for linen in England, as to restore the equilibrium without the transmission of money. But the effect, as respects the division of the advantage, is still as stated in the text.
