Individuals Want More Purchasing Power, Not More Money
Individuals do not want a greater amount of money in their pockets. Rather, they want greater purchasing power. In a free market, similar to other goods, the price of money is determined by supply and demand. All other things being equal, a decline in the supply of money causes an increase in the purchasing power of money. Conversely, purchasing power falls with an increase in the supply of money. Within a free market, there is no such thing as “too little” or “too much” money. As long as the market is allowed to clear, no “shortage of money” can emerge. According to Mises:“As the operation of the market tends to determine the final state of money’s purchasing power at a height at which the supply of and the demand for money coincide, there can never be an excess or deficiency of money.
“Each individual and all individuals together always enjoy fully the advantages which they can derive from indirect exchange and the use of money, no matter whether the total quantity of money is great, or small ... the services which money renders can be neither improved nor repaired by changing the supply of money. ...
“The quantity of money available in the whole economy is always sufficient to secure for everybody all that money does and can do.”
How Paper Certificates Displaced Gold as Money
Originally, paper money was not regarded as money, but merely as a representative of gold (i.e., a money substitute). Various paper certificates were claims on gold, which was stored with the banks. Holders of paper certificates could convert them into gold whenever they deemed necessary. Because people found it more convenient to use paper certificates to exchange for goods and services, these certificates came to be regarded as money.While convenient, paper certificates that are accepted as the medium of exchange open the scope for fraudulent practice. Banks could be tempted to boost their profits by lending certificates that were not covered by gold. In a free-market economy, a bank that over-issues certificates would quickly find out that the exchange value of its certificates, in terms of goods and services, will decline.
To protect their purchasing power, holders of the bank’s unbacked certificates are likely to attempt to convert them back to gold. Were all of them to demand gold back at the same time, this would bankrupt the bank. In a free market, then, the threat of bankruptcy would restrain banks from issuing paper certificates unbacked by gold. This means that in a free-market economy, paper money cannot assume a “life of its own” and become independent of commodity money.
To assert its authority, the central bank introduces its fiat certificate, which replaces the certificates of various banks. The central bank certificate is fully backed by bank certificates, which have the historical link to gold (hence, the continued purchasing power after gold is removed). The central bank certificate, labeled as “money” (i.e., legal tender) also serves as a reserve asset for banks. This enables the central bank to set a limit on the credit expansion by the banking system. (The purchasing power of the central bank’s “money” is established because of the fact that various certificates, which have purchasing power, are exchanged for the central bank certificate at a fixed rate.)
It would appear that the central bank could manage and stabilize the monetary system. The truth, however, is the exact opposite. To manage the system, the central bank must constantly generate money “out of thin air” (i.e., inflation) to prevent banks from bankrupting each other during the clearance of their checks. This leads to the persistent declines in the money’s purchasing power, and distorts the price structure and the structure of production, which destabilizes the entire monetary system.
No matter what scheme the central bank adopts (i.e., pumping money in line with economic growth or pumping money at a constant growth). Regardless of the mode of monetary injections, the boom-bust cycles are likely to become more ferocious as time passes.
Friedman’s scheme to fix the money growth rate at a given percentage does not solve the problem. After all, a fixed percentage growth is still money growth, which leads to the exchange of nothing for something (i.e., economic impoverishment and the boom-bust cycle). It is not surprising that the central bank must always resort to large monetary injections when there is a threat to the economy from various shocks. Such monetary pumping is the key cause that depletes savings and the potential for capital investment through the exchange of nothing for something.
