Chapter 6: Unemployment
Topical Outline and Key
Points
1. Unemployment and the “misery index”
a.
Is there a trade-off?
b.
What
is the natural rate of unemployment?
2. Job loss, Job finding, and the natural rate
of unemployment.
L = E + U (L is labor force, E is employed, U is unemployed)
fU = sE (f is rate of job finding, s
is rate of job separation)
U/L = s / (s + f ) (solve for natural rate of unemployment)
3.
Policies
must either reduce the separation rate or increase the finding rate to lower
the natural rate of unemployment.
4. Job search and frictional unemployment
a.
role of imperfect information
b.
sectoral (industry and region) shifts
c.
role of unemployment insurance
effect on separation rate and
finding rate
“just in time” personnel
management
proposals for reform (100 %
experience rated)
case study 5-1: empirical
evidence
5. Real-wage rigidity and wait unemployment (failure to “clear the labor market”
a.
minimum wage laws
traditional view
revisionist view (depends on “unrealized”
market power)
b.
unions and collective bargaining
insiders versus outsiders
(outsiders pay part of cost of high wages to insiders)
Canadian versus US experience
c.
efficiency
wages (high wages make workers more
productive)
6. Patterns of Unemployment
a.
duration (mostly short-term)
Long-term due to wait unemployment
b.
upward drift versus recent downward drift
composition of labor force
two income households
sectoral shifts due to oil
7. Transitions into and out of the labor force
a.
LIFO effect
b.
discouraged worker effect
c.
Eurosclerosis (Welfare state)
d.
Relative income (US) vs relative employment (Europe)
Key
Points in Chapter 6:
1. When the real wage adjusts to equate labor
supply and labor demand, we say that the market clears. When the market
clears, everyone who wants to work (labor supply) has a job (labor demand) at
the prevailing real wage, so we say that the economy has full employment of
labor.
2. The unemployment rate is not zero even if
the labor market is clearing. The natural rate of unemployment is the rate
of unemployment that occurs when the labor market clears. One purpose of this chapter is to explain
why the natural rate of unemployment is positive.
3. The natural rate of unemployment is given by
s/(s + f), where s = rate of job separation and f = rate of job finding. Any policy aimed at reducing the natural
rate of unemployment must either decrease s, increase f, or both. Existing public policy has ambiguous effects
in this area.
a.
Government employment placement agencies increase f
b.
Unemployment insurance decreases f
c.
Government job training programs try to decrease s by making workers
more productive and helping workers
develop good work habits.
4. The actual unemployment rate can exceed the
natural rate of unemployment because of a real wage rate that is “sticky” above
the market clearing real wage rate.
Unemployment created is called wait
unemployment. Causes of wage rigidity
include:
a.
Minimum wage laws
b.
Unions and collective bargaining
c.
Efficiency wages
5.
The
facts about unemployment
a.
Most
spells of unemployment are short, but most weeks of unemployment are
experienced by those who are unemployed over the long-term.
b.
Younger
persons have higher unemployment rates than older persons, primarily because of
higher separation rates. (Finding rates
are similar.)
c.
Non-white
persons have higher unemployment rates than whites because of both higher
separation rates and lower finding rates.
6.
Although
most of the analysis of this chapter assumes a constant labor force, in fact
transitions into and out of the labor force are very important.
a.
One-third
of the unemployed have only recently entered the labor force (LIFO effect)
b.
One-half
of all spells of unemployment end in withdrawal from the labor force
(discouraged worker effect.)
c.
The
presence of discouraged workers causes the unemployment rate to understate the
actual labor market impact of the business cycle.
