The Theory of Money and Credit - Ludwig von Mises [183]
In Germany there has been a controversy as to whether certain measures of the Reichsbank are dictated by regard to the circumstances of the domestic money market or to those of the international. In the form in which it is usually put, the question is meaningless. The mobility of capital goods, which nowadays is but little restricted by legislative provisions such as customs duties, or by other obstacles, has led to the formation of a homogeneous world capital market. In the loan markets of the countries that take part in international trade, the net rate of interest is no longer determined according to national, but according to international, considerations. Its level is settled, not by the natural rate of interest in the country, but by the natural rate of interest anywhere. Just as the exchange ratio between money and other economic goods is the same in all places, so also the ratio between the prices of goods of the first order and those of goods of higher orders is the same everywhere. The whole system of modern international trade would be completely changed if the mobility of capital goods were to be restricted. In Germany there are many who demand such a prohibition or at least a considerable restriction of the investment of capital abroad. It is not our task to demonstrate what a small prospect of success a policy like this would have, or to show that the time is now past for a nation to decide whether or not it will take part in international trade. So long and insofar, however, as a nation participates in international trade, its market is only a part of the world market; prices are determined not nationally but internationally. The fact that the rate of interest in Germany may rise, not because any change has occurred in its determinants within the Reich but because there have been changes, say, in the United States, should not seem any more remarkable than, say, a rise in the price of corn that is due to the state of foreign harvests.
It has not been easy to reconcile policy with the extension and combination of national markets into a world market. Stronger than the resistance encountered centuries ago by the development of the town economy into the national economy is that which the nineteenth and twentieth centuries have opposed to the further stage of development into a world economy. Nowadays there is nothing like the feeling of homogeneity which previously overcame regional interests; the pronounced emphasis upon national antagonisms which sets the keynote of modern policy would perhaps stand in the way of attempts at economic unification even if there were no interests to which these attempts might prove injurious. From the point of view of the producer, low prices seem to be the greatest of all evils, and in every state those producers who are unable to meet competition strive with all the means at their disposal to keep the cheap commodities
