Chapter 26
Money and Inflation
• Milton Friedman stated “inflation is always
and everywhere a monetary phenomenon”
• We will perform some thought experiment
and empirical investigation.
Thought experiment
• In an economy, if money supply doubles
and real economy remains the same, will
there be inflation?
• In an economy, if money supply remains
the same and real economy shrinks by
half, will there be inflation?
Thought experiment (Continued)
• If a country is an oil consumer and the
market price of oil increases, can a
monetary policy be applied to maintain
zero inflation rate without affecting the
living standard?
Empirical evidences
• In the textbook, several historical
examples were used to support
Friedman’s view. We will reinvestigate
these examples.
– Germany
– Latin America
Germany (1921-1923)
• Keynes, in his The economic
consequences of the peace, had warned
explicitly the disastrous impact of the
reparations imposed on Germany
Germany (1921-1923)
• In the textbook, it stated,
• The invasion of the Ruhr and the printing of
currency to pay striking workers fit the
characteristics of an exogenous event.
• However, the invasion of the Ruhr by the French
can hardly be classified as an exogenous event.
It is an integral part of the enforcement of the
reparations that put great burden over German
people and the German government.
Germany (1921-1923)
• The reparations were explicitly designed to
permanently weaken German economy. It
is a little more than disingenuous to blame
the resulting economic disaster in
Germany on the victims themselves.
Latin America
• In the textbook, it states
• The explanation for the high rates of
money growth in these countries is similar
to the explanation for Germany during its
hyperinflation. The unwillingness of
Argentina, Brazil, and Peru to finance
government expenditures by raising taxes
led to large budget deficits, which were
financed by money creation.
• It is interesting to note that economists,
who usually promote low tax rates to
stimulate incentives in domestic politics,
rarely shy away from advocating high tax
burden on already impoverished people in
foreign countries. Why?
• What are government expenditures in
these countries exactly?
• They include paying heavy interest on
foreign debt. This is very similar to
Germany after WWI. All these rapid
inflations have the common property of
huge foreign debts, which greatly crippled
their domestic economy and impoversihed
local people.
from Stiglitz
• But it soon became obvious that this was not what the
IMF was all about at all … That was not their mindset.
They were interested in one thing. They looked at the
country and thought, “they need to repay the loans they
owe to Western banks. How do they get that happen?
So they would never ask, “should we give this
developing country a bankruptcy procedure so they can
have a fresh start?” They thought that bankruptcy was a
violation of the sanctity of contracts, even though every
democracy has a bankruptcy law for people who have
persistently failed. They were interested in milking
money out of the country quickly, not rebuilding it for the
long term.
• Can monetary policy alone insure good
economic performance, as claimed by many
monetarists?
• Slashing government program and raising taxes
will hurt living standard.
• Can you resolve your personal financial deficit
by borrowing alone?
• There is no painless way out of a persistent
deficit, whether at a personal level or country
level.
• From the textbook,
• To sum up, although high inflation is “always and
everyewhere a monetary phenomenon” in the
sense that it cannot occur without high rate of
monetary growth, there are reasons why this
inflationary monetary policy might come about.
The two underlying reasons are the ahdherence
of policymakers to a high employment target and
the presence of persistent government budget
deficits. (p. 654)
• If we look at today’s BC and Alberta economy, it
is difficult not to have a high employment rate
and to run government deficit. Therefore,
underlying economic condition is the most
important factor affecting inflation and other
monetary phenomena.
• Simply put, living beyond one’s mean, whether
at personal and scale bigger, is unsustainable.
Some empirical evidence
• However, the linkage between money
growth and inflation after 1980 is not at
evident in Figure 26-8. (p. 656)
• It would to better to combine the economic
output and money output to understand
inflation.

Extra homework
•
•
Inflation rate is calculated from the weighted average of price increase from the various
economic products. Since people tend to decrease spending on products whose prices
increases substantially and increase spending on products whose prices decline or increase
less, the change of weights of consumer spending often highly correlated with price changes.
This may make CPI a less reliable measure of inflation over a long period of time. We will use
a numerical example to illustrate this. Suppose there are two products in an economy. Initially,
product A is weighted 30% in economy and product B is weighted 70%. In the first period of
time, product B’s price increased by 20% and product A’s price remains the same. In period 1,
product A is weighted 70% in economy and product B is weighted 30%. Calculate the CPI of
the economy is period 1. In the second period of time, product A’s price increased by 20% and
product B’s price remains the same. In period 2, product B is weighted 70% in economy and
product A is weighted 30%. Calculate the CPI of the economy is period 2. What is the average
of inflation rate in the two time periods calculated from the average of CPI? If we calculate the
average inflation rate from the price data from the beginning to end, what will be the average
inflation rate? Which number reflect the reality more truthfully? Why?
In an economy, if money supply doubles and real economy remains the same, will there be
inflation? In an economy, if money supply remains the same and real economy shrinks by half,
will there be inflation? Milton Friedman stated that “inflation is always and everywhere a
monetary phenomenon”. Do you agree or not? Why?
