The Theory of Money and Credit - Ludwig von Mises [4]
The example of Great Britain was followed by other countries, notably by the United States. President Roosevelt reduced the gold content of the dollar because he wished to prevent a fall in wages and to restore the price level of the prosperous period between 1926 and 1929.
In central Europe, the first country to follow Great Britain's example was the Republic of Czechoslovakia. In the years immediately after the war, Czechoslovakia, for reasons of prestige, had heedlessly followed a policy which aimed at raising the value of the krone, and she did not come to a halt until she was forced to recognize that increasing the value of her currency meant hindering the exportation of her products, facilitating the importation of foreign products, and seriously imperiling the solvency of all those enterprises that had procured a more or less considerable portion of their working capital by way of bank credit. During the first few weeks of the present year, however, the gold parity of the krone was reduced in order to lighten the burden of the debtor enterprises, and in order to prevent a fall of wages and prices and so to encourage exportation and restrict importation. Today, in every country in the world, no question is so eagerly debated as that of whether the purchasing power of the monetary unit shall be maintained or reduced.
It is true that the universal assertion is that all that is wanted is the reduction of purchasing power to its previous level, or even the prevention of a rise above its present level. But if this is all that is wanted, it is very difficult to see why the 1926-29 level should always be aimed at, and not, say, that of 1913.
If it should be thought that index numbers offer us an instrument for providing currency policy with a solid foundation and making it independent of the changing economic programs of governments and political parties, perhaps I may be permitted to refer to what I have said in the present work on the impossibility of singling out any particular method of calculating index numbers as the sole scientifically correct one and calling all the others scientifically wrong. There are many ways of calculating purchasing power by means of index numbers, and every single one of them is right, from certain tenable points of view; but every single one of them is also wrong, from just as many equally tenable points of view. Since each method of calculation will yield results that are different from those of every other method, and since each result, if it is made the basis of practical measures, will further certain interests and injure others, it is obvious that each group of persons will declare for those methods that will best serve its own interests. At the very moment when the manipulation of purchasing power is declared to be a legitimate concern of currency policy, the question of the level at which this purchasing power is to be fixed will attain the highest political significance. Under the gold standard, the determination of the value of money is dependent upon
