3.  The business cycle occurs when economic
activity speeds up or slows down.
 A business cycle is a swing in total national
output, income and employment, usually
lasting for a period of 2 to 10 years, marked by
widespread expansion or contraction in many
sectors of the economy.

4. Q Business cycles are the
irregular expansions and
Potential output contractions in economic
activity.
Actual output
t (in years)

5.  Economic theory define three types of
business cycle:
 Short-term (Kitchin) cycle: from 2 to 4 years,
it results from the changes in business
inventories.
 Medium-term (Jouglar) cycle: from 7 to 11
years, it refers to new business investment.
 Long-term (Kondratiev) cycle: from 30 to 50
years, it results from the technological
innovation.

6.  A business cycle can be divided into
four major phases:
 Recession – the downturn of a business cycle. This
is a period in which real GDP declines for at least 2
consecutive quarter-years.
 Trough – the lowest point of real GDP at the end of
a recession.

7.  Expansion (boom) is a period in which output
increases and approaches potential GDP or
perhaps even overshoots it.
 Peak – the point at which recession begins, the
highest point in real GDP before a recession.

8.  Business cycle generally occurs as a
result of shifts in the AD. Decline in the
AD lowers output and as a result of
downward shift in the AD curve, the gap
between actual and potential GDP
becomes greater during a recession.

9. P AS Characteristics of the recession:
QP
•Consumers purchases decline and
businesses react by holding back
AD
production. Real GDP falls.
AD1 Businesses investment also falls.
•The demand for labor falls.
•The prices of many commodities fall.
E
Wages are less likely to decline, but
P
they tend rise less rapidly.
P1 E1 •Business profit fall, because the
demand for credit falls, interest rates
