Money in a Free Society
10. Stabilize the Price Level?
Some theorists charge that a free monetary system would be unwise, because it would not "stabilize the price level," i.e., the price of the money-unit. Money, they say, is supposed to be a fixed yardstick that never changes. Therefore, its value, or purchasing power, should be stabilized. Since the price of money would admittedly fluctuate on the free market, freedom must be overruled by government management to insure stability.  Stability would provide justice, for example, to debtors and creditors, who will be sure of paying back dollars, or gold ounces, of the same purchasing power as they lent out.
Yet, if creditors and debtors want to hedge against future changes in purchasing power, they can do so easily on the free market. When they make their contracts, they can agree that repayment will be made in a sum of money adjusted by some agreed-upon index number of changes in the value of money. The stabilizers have long advocated such measures, but strangely enough, the very lenders and borrowers who are supposed to benefit most from stability, have rarely availed themselves of the opportunity. Must the government then force certain "benefits" on people who have already freely rejected them? Apparently, businessmen would rather take their chances, in this world of irremediable uncertainty, on their ability to anticipate the conditions of the market. After all, the price of money is no different from any other free prices on the market. They can change in response to changes in demand of individuals; why not the monetary price?
Artificial stabilization would, in fact, seriously distort and hamper the workings of the market. As we have indicated, people would be unavoidably frustrated in their desires to alter their real proportion of cash balances; there would be no opportunity to change cash balances in proportion to prices. Furthermore, improved standards of living come to the public from the fruits of capital investment. Increased productivity tends to lower prices (and costs) and thereby distribute the fruits of 383 free enterprise to all the public, raising the standard of living of all consumers. Forcible propping up of the price level prevents this spread of higher living standards.
Money, in short, is not a "fixed yardstick." It is a commodity serving as a medium for exchanges. Flexibility in its value in response to consumer demands is just as important and just as beneficial as any other free pricing on the market.
How the government would go about this is unimportant at this point. Basically, it would involve governmentally-managed changes in the money supply.
