Money and The
Business Cycle
Gregory T.

Money
is critical to any market economy because money allows people to exchange
property without direct barter. Thus money facilitates and accelerates
transactions, and thus accelerates the market process in which the highest
valued use of every good, service and commodity is found. Money is also
necessary for people to do proper accounting to determine whether they are
making a profit or a loss on their current economic activity. It is this
accounting that allows firms to discern whether they are in the right industry,
making their product the right way, and selling it at the right price. Money is whatever is used for buying and
selling things. In other words, money is the medium of exchanging property
rights and keeping account of the profits and losses from those exchanges. There
are seven criteria that something must meet to be used as money. 1. It must be
widely valued so that people will be willing to trade away other valuable
things to get it. 2. It must be easy to transport so that people can get it to the
physical trading site where they can buy what they want. 3. It must be scarce
enough so that small, easy to carry and measureable amounts of it can be used
to complete most transactions. 4. It must be imperishable so that people can
save it long enough to find a use for it that they judge to be worthwhile. 5. It
must be easy to store so that people can always put it somewhere safe when they
are not using it and retrieve it immediately when there is a transaction that
they want to complete. 6. It must be easily divisible so that people can make
change in any transaction and pay the exact price of whatever they buy. 7. Every
unit of it must be interchangeable so that people can always tell how much they
are paying or receiving in any transaction. The relationship between money and
the overall economy has critical implications for public policy. Every major
school of thought identifies money as a key element in the business cycle. The
business cycle is the periodic fluctuation of the overall amount of output that
is bought and sold and the resulting fluctuation in unemployment.
Every
country imposes a monopoly on the creation of money within its own borders. In
most developed countries the government delegates its power to create money to
an agency called a central bank. Central banks create money by buying financial
assets, usually government bonds, from private banks with money that did not
exist before the purchase. Private banks then use the new money that they made
from selling the assets, called reserves, to make loans. Banks do not actually
loan out their reserves or the money of their depositors. Rather, banks create
the money that they loan out at the moment that they make the loan by simply
entering it into their ledgers. What stops banks from loaning out infinite
money and rendering the currency useless is that every country imposes a legal
limit, defined by the ratio of reserves to deposits, on the amount of money
that banks can have in outstanding loans. This method of controlling the money
supply is called fractional reserve banking. This may seem to contradict the
government having monopoly on the creation of money. However, the central bank
still controls the overall money supply by controlling the amount of available
reserves. Thus the central bank and, therefore, the government still maintains
de facto control over the amount of money in circulation at any given time. In
economics there is a fevered debate about the role of the central bank in the
business cycle. The Keynesian school of thought teaches that central banks
should use their power to create money to smooth out fluctuations in aggregate
demand, or total spending, in order to maintain full employment of labor and
other resources. Keynesianism teaches that prices do not adjust to clear the
market fast enough in response to changes in total spending. The Austrian school
maintains that Keynesianism cannot tell us why aggregate spending fluctuates at
all. Keynesians usually argue that booms and recessions are self-fulfilling
prophecies. When people believe that the economy is doing well, they assume
that they will have higher income in the future. This encourages people to spend
and invest more money, which leads to actual higher future income. Equivalently, Keynesians argue that when
people believe that the economy is getting worse, they assume that they will
have less income in the future and thus cannot afford to spend as much money in
the present, thus causing a recession. Austrians counter by arguing that
Keynesian theory provides no explanation for why people’s expectations about
the future of the economy and thus the future of their own personal finances
change at all. Thus Keynesianism cannot explain why we do not have either a
perpetual boom or a perpetual recession.
The
Austrian school teaches that prices adjust to clear all markets, including the
labor market, on their own in both the short run and the long run. Thus
equilibrium in the labor market, otherwise known as full employment, is
compatible with any amount of money in the economy according to Austrian
theory. The Austrian school teaches that the ultimate cause of the business
cycle is the government monopoly on money which it exercises through the
central bank. By manipulating the money supply, the central bank misleads
entrepreneurs about the amount of investment that the savings rate will
support. The Austrian school teaches that the business cycle will not occur and
unemployment will not fluctuate so long as the real interest rate, the interest
rate adjusted for inflation, accurately reflects the consumer’s willingness to
sacrifice future consumption for present consumption by borrowing money and
paying interest. Equivalently, the economy shall operate at full employment if
the interest rate accurately reflects loaners’ willingness to sacrifice present
consumption by saving and loaning out money for future consumption, made
possible by repayment of the loan plus interest. In other words, the economy
will operate at full employment so long as the interest rate equals the opportunity
cost of additional loans. The Austrian school teaches that the central bank
causes booms by lowering the interest rate to below optimal levels and thus
causing more money to be loaned than the consumer’s saving can finance. This
leads to entrepreneurs overestimating the consumer’s willingness to save, thus
overestimating their willingness to pay for goods in the future. This makes
entrepreneurs borrow too much money and spend too much money on new capital
goods, thus devoting capital goods to the production of consumer goods that
consumers do not want. The boom inevitably leads to a recession once
entrepreneurs realize that people do not want to buy their products and that
the interest rate does not accurately reflect people’s desire for future consumption.
So the boom lasts until entrepreneurs realize that the central bank has fooled
them and the recession lasts until the central bank discovers a new way to fool
entrepreneurs. Thus the boom inevitably transforms into a recession as
entrepreneurs realize that their investments will not pay off because people
are not willing to spend as much money as the interest rate indicates. This
raises the question of why entrepreneurs cannot tell when the central bank is
lowering the interest rate to below optimal levels and thus deduce that they
should not buy as much capital as they would buy otherwise. The answer is that
the central bank’s control over the real interest rate ensures that neither
entrepreneurs nor anyone else can ever tell what interest rate truly reflects
the consumer’s willingness to sacrifice future consumption for present
consumption by borrowing money and paying interest. Thus entrepreneurs never
know whether the interest rate is above the correct level or below the correct
level until after the fact. Governments pressure central banks into lowering
the interest rate and thus creating booms because this makes it easier for
governments to borrow money and thus finance politically important projects.
The
Austrian prescription for ending the business cycle is to eliminate the
government monopoly on currency entirely and allow private banks to issue their
own currency backed by gold or some other commodity that satisfies the seven
criteria for being good money. Austrians argue that if each bank could issue
its own currency backed by gold, then the central bank would be unable to
manipulate interest rates and the interest rate would reach the level that
accurately reflects the opportunity cost of making an additional loan on its
own. If their currencies were backed by gold, then banks would not issue too
much of their currency and thus not create lower than optimal interest. Any
bank that issued more currency than their gold reserves support would provoke
their competitors into buying their currency and redeeming it for gold that the
issuing bank does not have, thus bankrupting the issuer and running them out of
business. Thus the private banks would effectively regulate each other if they
issued their own gold-backed currencies. The normal argument for the government
monopoly on money is that having only one currency rather than many currencies
reduces transaction costs by removing the need to switch between currencies.
The problem with this argument is that it only makes sense under the assumption
that the currency market is a natural monopoly. If that were the case, then
only one currency would endure and the government would have no need to give
itself a monopoly on money to create a single currency economy. Moreover, the
market has internalized the transaction costs of switching between currencies
of different countries through the foreign exchange market. There is no obvious
reason why an equivalent domestic exchange market would not emerge if the
government ended its monopoly on currency and private currencies emerged. Once
the transaction costs of switching currencies are internalized into a
competitive market they cease to be an impediment to economic efficiency. In
summary, the Austrian theory of how money relates to the business cycle implies
that the optimal response to the business cycle is not actively manipulating
the money supply because active manipulation of the money supply causes the
business cycle. Rather, the optimal response is to eliminate the government
monopoly on money and to trust that the market will produce the optimal amount
of money on its own.
