Categorize each of the following sets of circumstances as
frictional, structural, or cyclical unemployment.
a) Sanjit, a pulp-mill worker, is laid off because the mill’s
inventories are at an all-time high.
b) Five weeks ago, Alison left a job she did not like and is
still looking for another job.
c) Ian was a fisher on the East Coast but sold his boat after

Criticisms of the Official Rate
The reported unemployment rate may be:
• Understated because part-timers are included as
full-timers;
• Understated because it excludes discouraged
workers;
• Overstated because of false information from
some EI recipients; or
• Overstated because of false information from
those working in the underground economy

Costs of Unemployment
Okun’s Law
• for every 1 percent of cyclical unemployment an
economy’s GDP is 2.5 percent below its potential
GDP gap = 2.5  cyclical unemployment (%) 
actual GDP (real or nominal)
Example: if UE = 8%, natural rate = 6%, GDP = $1622 b
GDP gap = 2.5 x 2% x $1622 billion
= $81.1 billion
