2. The Instruments of Monetary Policy

The principal instrument of monetary policy at the disposal of the state is the exploitation of its influence on the choice of the kind of money. It has been shown above that the position of the state as controller of the mint and as issuer of money substitutes has allowed it in modern times to exert a decisive influence over individuals in their choice of the common medium of exchange. If the state uses this power systematically in order to force the community to accept a particular sort of money whose employment it desires for reasons of monetary policy then it is actually carrying through a measure of monetary policy. The states which completed the transition to a gold standard a generation ago, did so from motives of monetary policy. They gave up the silver standard or the credit-money standard because they recognized that the behavior of the value of silver or of credit money was unsuited to the economic policy they were following. They adopted the gold standard because they regarded the behavior of the value of gold as relatively the most suitable for carrying out their monetary policies.

If a country has a metallic standard, then the only measure of currency policy that it can carry out by itself is to go over to another kind of money. It is otherwise with credit money and fiat money. Here the state is able to influence the movement of the objective exchange value of money by increasing or decreasing its quantity. It is true that the means is extremely crude, and that the extent of its consequences can never be foreseen. But it is easy to apply and popular on account of its drastic effects.
