CHAPTER 1 THE ATTEMPT TO DISCOVER A STABLE STANDARD § 1. The nature of a monetary standard and the measure of values. In a preceding chapter we have attempted to lay down what is customarily understood by a monetary standard in current language and in the language of economists. We have seen that in defining a monetary system which in- cludes various kinds of instruments of exchange, the economists have used this phrase to describe that instru- ment which appears to be the basis of the system and from which the other monetary instruments appear to derive their own exchange value owing to convertibility. We have observed that in fact the only objective criterion which in a monetary system distinguishes the basic currency is to be found in international payments, and that it is the cur- rency which can also circulate abroad—usually after mere physical transformation—which is held to be the standard currency. Finally, we saw that although this currency, which remains legal tender abroad, is usually metal, its position as a standard currency is not essentially due to its being a commodity. For under the system of free coinage a monetary metal has a special market which enables it to be exchanged with certainty for a given number of units of account, the value of which, while originally it was connected with that of a commodity currency, has become independent of the value of the material in which it is embodied. And so, when we speak of the gold stan- dard, the expression has a different meaning, viz., that a monetary system so defined involves a stable exchange ratio—metallic par—between its monetary unit and the 183
