2.2: the business cycle and the level of economic activity
Overview
level of economic activity,
measured by GDP, fluctuates
creates a wave know as the business cycle
Business Cycle - wave like ups and downs in a
nations level of production or economic activity.
business cycle diagram has two key points.
1. has swings in production levels & 2.
long term trend line for national input.
Short to medium term cyclical swings in economic activity
level of economic activity is
always changing
repeated once completed
Main phases of the business cycle
4 main phases
1. Expansion or
recovery phase
starts at lower levels, than there is an
expansion in economic activity
slow at first but picks up later
employment grows, unemployment falls
and inflation increases
2. The peak
(sometimes a boom)
phase
period of expansion where
economic activity reaches its peak
unemployment is low, inflation high
peak occurs then we are at
productive capacity and a boom
may result
growth rates tail off and may
not be fast
Boom - period of
strong spending and
above average levels
of economic activity,
usually associated
with rapid demand
inflation and very low
unemployment.
3. The slowdown or
contraction phase
normally follow a
peak or boom
growth in GDP
slows. Sever
production may fall
unemployment rises
and inflation eases
4. The trough (sometimes recession) phase
lowest point on cycle
slight rise in unemployment
Enter text here
GDP falls twice we go
into a recession where
inflation is negative
Long and severe troughs
are known as depression.
Depressions- large
economic downturn in
production associated with
very high cyclical
unemployment and is
caused by significant fall in
aggregate demand
Recession- period of weak spending and
is associated with high levels of cyclical
unemployment
The 'ideal' level of economic activity
ideal at
domestic
economic
stability
Domestic Economic Activity - desirable level of
economic activity where there is low inflation, a solid
and sustainable rate of GDP and low unemployment
midway b/w extremes of peaks and troughs
point on trend line
not too rapid or too slow
Aus gov uses aggregate demand (AD)
management to steer the level of economic
activity towards the ideal situation
Special situation of 'stagflation'
Stagflation - period of slow GDP growth along
with high unemployment and rapid inflation
experiences a stagnant (no activity)
level of production or activity combined
with high costs and inflation and
structural unemployment
Long term trend line or sustainable
speed limit for economic activity
rises in economic
activity outweighs
the falls
average trend lines slopes upwards
trend lines represents a nations average
sustainable rate of economic growth that could
be achieved. Taken into account is the limited
production, the volume of resources and efficient
use of resources
steeper trend line shows that a countries
productive capacity, enabling economic
activity to rise and cause serious inflation
Productive Capacity - potential level of national
production of goods and services dictated by the
quantity and efficiency of a nations resources.
Determines the sustainable rate of economic
growth in the long term
