If labor markets tend to equilibrium, why is unemployment always

If labor markets tend to equilibrium, why is
unemployment always present?
Some unemployment is compatible with equilibrium
Equilibrium level of unemployment
Natural rate of unemployment
Full employment level of unemployment
Labor Market as a Game of Musical Chairs
At equilibrium unemployment
job vacancies = job seekers
=
Frictional Unemployment
Even when seekers equal vacancies, it
takes time for the market to clear
“Between Jobs”
Periods of low unemployment
Magnitude of flows in May 1993
• In one month
– 5 million leave employment
– 5 million enter employment
– ~7.8% (10mil/128.1mil) of labor force change
employment status every month
– 3.5 million leave unemployment
– 3.5 million enter unemployment
– ~5.5% of labor force change unemployment status
every month
Expected unemployment duration
• Suppose probability p of leaving
unemployment in one month
• Random draw on job
– Probability you get a job in any month = p
–
you stay unemployed = (1-p)
– Expected duration = (1/p)
FIGURE 15.1 Labor Market Stocks and Flows: May 1993
p = (2/8.9) = .224
Duration = 1/p = 4.5 mo.
p = ([2=1.5]/8.9) = .393
Duration = 1/p = 2.5 mo.
Average = 3 months (14 weeks);
Peak = 4.7 months (21 weeks)

Problem unemployment
Cyclical Unemployment—unemployment
associated with national business cycles
(recession)
Structural unemployment: localized shortfall
of demand (geographic (Appalachia);
