We face one of the deepest crises in history. A
prognosis for the economic future requires a deepening of the concepts of
inflation and deflation. Without understanding their dynamic relationship and their implications is
difficult to predict how things might unfold. The economic future depends on
the interplay of both these forces. From the point of view of their final
effects, inflation and deflation are, respectively, the devaluation and
revaluation of the currency unit. The quantity theory of money developed in
1912 by the American economist Irving Fisher asserts that an increase in the
money supply, all other things been equal, results in a proportional increase
in the price level [1]. If the circulation of money signifies the aggregate
amount of its transfers against goods, its increase must result in a price
increase of all the goods. The theory must be viewed through the lens of the
law of supply and demand: if money is abundant and goods are scarce, their
prices increase and currency depreciates. Inflation rises when the monetary
aggregate expands faster than goods. Conversely, if money is scarce, prices
fall and the opposite, deflation, occurs. In this case the monetary aggregate
shrinks faster than goods and as prices decrease money appreciates.
Inflation is a political phenomenon because monetary
aggregates are not determined by market forces but are planned by central banks
in agreement with governments. It is in fact connected with the monetary expansion to fund their
deficits. Inflation raises the demand for goods and decreases the demand for
money; it increases aggregate spending and money velocity as the ratio between
GDP and the amount of money in circulation which expresses the rapidity with
which the monetary unit is spent and respent until it remains in existence.
There is no such things as demand-pull inflation or
cost-push inflation. Provided
that the quantity of money does not increase, if cost or demand for some goods
changes, demand for other goods must necessarily adjust, leaving unchanged the
amount of spending and the money aggregate in the economic system. If some
people spend more, others have to spend less, thus leaving the purchasing power
unaltered. The cause of inflation is nothing but money manipulation.
