Principles Of Political Economy

§ 1. The substitution of money for barter makes no difference in exports and imports, nor in the Law of international Values.

Having now examined the mechanism by which the commercial transactions between nations are actually conducted, we have next to inquire whether this mode of conducting them makes any difference in the conclusions respecting international values, which we previously arrived at on the hypothesis of barter.

The nearest analogy would lead us to presume the negative. We did not find that the intervention of money and its substitutes made any difference in the law of value as applied to adjacent places. Things which would have been equal in value if the mode of exchange had been by barter are worth equal sums of money. The introduction of money is a mere addition of one more commodity, of which the value is regulated by the same laws as that of all other commodities. We shall not be surprised, therefore, if we find that international values also are determined by the same causes under a money and bill system as they would be under a system of barter, and that money has little to do in the matter, except to furnish a convenient mode of comparing values.

All interchange is, in substance and effect, barter; whoever sells commodities for money, and with that money buys other goods, really buys those goods with his own commodities. And so of nations: their trade is a mere exchange of exports for imports; and, whether money is employed or not, things are only in their permanent state when the exports and imports exactly pay for each other. When this is the case, equal sums of money are due from each country to the other, the debts are settled by bills, and there is no balance to be paid in the precious metals. The trade is in a state like that which is called in mechanics a condition of stable equilibrium.

But the process by which things are brought back to this state when they happen to deviate from it is, at least outwardly, not the same in a barter system and in a money system. Under the first, the country which wants more imports than its exports will pay for must offer its exports at a cheaper rate, as the sole means of creating a demand for them sufficient to re-establish the equilibrium. When money is used, the country seems to do a thing totally different. She takes the additional imports at the same price as before, and, as she exports no equivalent, the balance of payments turns against her; the exchange becomes unfavorable, and the difference has to be paid in money. This is, in appearance, a very distinct operation from the former. Let us see if it differs in its essence, or only in its mechanism.

Let the country which has the balance to pay be the United States,[276] and the country which receives it, England. By this transmission of the precious metals, the quantity of the currency is diminished in the United States, and increased in England. This I am at liberty to assume. We are now supposing that there is an excess of imports over exports, arising from the fact that the equation of international demand is not yet established: that there is at the ordinary prices a permanent demand in the United States for more English goods than the American goods required in England at the ordinary prices will pay for. When this is the case, if a change were not made in the prices, there would be a perpetually renewed balance to be paid in money. The imports require to be permanently diminished, or the exports to be increased, which can only be accomplished through prices; and hence, even if the balances are at first paid from hoards, or by the exportation of bullion, they will reach the circulation at last, for, until they do, nothing can stop the drain.

When, therefore, the state of prices is such that the equation of international demand can not establish itself, the country requiring more imports than can be paid for by the exports, it is a sign that the country has more of the precious metals, or their substitutes, in circulation, than can permanently circulate, and must necessarily part with some of them before the balance can be restored. The currency is accordingly contracted: prices fall, and, among the rest, the prices of exportable articles; for which, accordingly, there arises, in foreign countries, a greater demand: while imported commodities have possibly risen in price, from the influx of money into foreign countries, and at all events have not participated in the general fall. But, until the increased cheapness of American goods induces foreign countries to take a greater pecuniary value, or until the increased dearness (positive or comparative) of foreign goods makes the United States take a less pecuniary value, the exports of the United States will be no nearer to paying for the imports than before, and the stream of the precious metals which had begun to flow out of the United States will still flow on. This efflux will continue until the fall of prices in the United States brings within reach of the foreign market some commodity which the United States did not previously send thither; or, until the reduced price of the things which she did send has forced a demand abroad for a sufficient quantity to pay for the imports, aided perhaps by a reduction of the American demand for foreign goods, through their enhanced price, either positive or comparative.
