Inflation Cycles
In the long run, inflation occurs if the quantity of money
grows faster than potential GDP.
In the short run, many factors can start an inflation, and
real GDP and the price level interact.
To study these interactions, we distinguish two sources of
inflation:
▪ Demand-pull inflation
▪ Cost-push inflation
Demand-Pull Inflation
An inflation that starts because aggregate demand
increases is called demand-pull inflation.
Demand-pull inflation can begin with any factor that
increases aggregate demand.
Examples are a cut in the interest rate, an increase in the
quantity of money, an increase in government expenditure,
a tax cut, an increase in exports, or an increase in
investment stimulated by an increase in expected future
profits
Initial Effect of an
Increase in Aggregate
Demand
Starting from full employment, an increase in aggregate demand
shifts the AD curve rightward
The price level rises, real GDP increases, and an inflationary gap arises.
The rising price level is the first step in the demand-pull inflation
Money Wage Rate
Response
The price level rises and
real GDP decreases back
to potential GDP.
Cost-Push Inflation
An inflation that starts with an increase in costs is called
cost-push inflation.
There are two main sources of increased costs:
1. An increase in the money wage rate
2. An increase in the money price of raw materials, such
as oil
A Demand-Pull Inflation
Process
Aggregate demand keeps increasing and the process just described repeats indefinitely
Several factors can increase aggregate demand to start a demand-pull inflation, …
but only an ongoing increase in the quantity of money can sustain it.
A demand-pull inflation occurred in Canada in the early 1970s when
inflation hit double digits by 1974.
Initial Effect of a Decrease
in Aggregate Supply
If oil producers cut
production and raise the
price of oil, short-run
aggregate supply decreases
and the SAS curve shifts
leftward.
Real GDP decreases and
the price level rises.
Aggregate Demand Response
The initial increase in costs creates a one-time rise in the
price level, not inflation.
To create inflation, aggregate demand must increase.
That is, the Bank of Canada must respond to the
unemployment and increase the quantity of money
persistently.
The Bank of Canada
stimulates aggregate
demand to counter the
higher unemployment.
Real GDP increases and
the price level rises again.
A Cost-Push Inflation
Process
If the oil producers raise the oil price to try to keep its relative price higher, …
and the Bank of Canada responds by increasing the quantity of money, …
a process of cost-push inflation continues.
The combination of a rising price level and a decreasing real GDP is
called stagflation.
Cost-push inflation occurred in Canada during the 1970s when the Bank responded to the OPEC oil price rise.
Expected Inflation
Aggregate demand increases, but the increase is expected, so its effect on the price level is expected.
The money wage rate rises in line with the expected rise in the
price level.
The price level rises as expected and real GDP remains at
potential GDP. The process repeats.
Forecasting Inflation
To expect inflation, people must forecast it.
The best forecast available is one that is based on all the
relevant information and is called a rational expectation.
A rational expectation is not necessarily correct, but it is
the best available.
The Quantity Theory and Deflation
Inflation rate = Money growth rate + Rate of velocity change
– Real GDP growth rate
Deflation occurs if
Money growth rate < Real GDP growth rate – Rate of
velocity change.
Inflation and the Business Cycle
When the inflation forecast is correct, the economy
operates at full employment.
If aggregate demand grows faster than expected, real
GDP moves above potential GDP, …
the inflation rate exceeds its expected rate and the
economy behaves like it does in a demand-pull inflation.
If aggregate demand grows more slowly than expected, …
real GDP falls below potential GDP, inflation slows, and
the economy behaves like it does in a cost-push inflation.
Deflation
An economy experiences deflation when it has a
persistently falling price level.
▪ What causes deflation?
▪ What are the consequences of deflation?
▪ How can deflation be ended?
The price level falls persistently if aggregate demand
increases at a persistently slower rate than aggregate
supply.
What are the Consequences of Deflation?/How can deflation be ended?
What are the Consequences of Deflation?
Unanticipated deflation redistributes income and wealth,
lowers real GDP and employment, and diverts resources
from production.
How can deflation be ended?
By increasing the growth rate of money.
Make the money growth rate exceed the growth rate of
real GDP minus the rate of velocity change.
The Phillips Curve
A Phillips curve is a curve that shows the relationship
between the inflation rate and the unemployment rate.
There are two time frames for Phillips curves:
▪ The short-run Phillips curve
▪ The long-run Phillips curve
The Long-Run Phillips Curve
The long-run Phillips curve shows the relationship
between inflation and unemployment when the actual
inflation rate equals the expected inflation rate.
The long-run Phillips curve (LRPC) is vertical at the natural unemployment rate.
Along LRPC, a change in the inflation rate is expected, so the
unemployment rate remains at the natural unemployment rate.
The Short-Run Phillips Curve
The short-run Phillips curve shows the tradeoff between
the inflation rate and unemployment rate, holding constant
1. The expected inflation rate
2. The natural unemployment rate
With a given expected inflation rate and natural unemployment rate: If the inflation rate is exceeds the expected inflation rate, the unemployment rate decreases.
If the inflation rate is below the expected inflation rate, the
unemployment rate increases.
The Federal Budget
The federal budget is the annual statement of the federal
government’s outlays and revenues.
The federal budget has two purposes:
1. To finance the activities of the federal government
2. To achieve macroeconomic objectives
Change in the Natural
Unemployment Rate
A change in the natural unemployment rate shifts both the long-run and short-run Phillips curves.
Fiscal policy
is the use of the federal budget to achieve
macroeconomic objectives, such as full employment,
sustained economic growth, and price level stability.
Budget Making
The federal government and Parliament make fiscal policy.
After a long, draw-out process of consultations, the
Minister of Finance presents a budget plan to Parliament.
Parliament debates the plan and enacts the laws
necessary to implement it.
Budget Balance
The federal government’s budget balance equals
revenues minus outlays.
If revenues exceed outlays, the government has a
budget surplus.
If outlays exceed revenues, the government has a
budget deficit.
If revenues equal outlays, the government has a
balanced budget.
Government revenues come from four sources:
Personal income taxes – largest revenue source
Corporate income taxes – smallest source
Indirect and other taxes – second largest source
Investment income
