THE
FOUR BIG MACROECONOMIC
ISSUES AND THEIR
INTER-RELATIONSHIPS
To
study any major issue or
problem in macroeconomics, it is
important to address at least
three
questions
about
it:
i.
Why is it important (i.e.
what are its
costs);
ii.
What are its causes or
the possible diagnoses of
the problem; and
iii.
What is the policy
prescription associated with
each different
diagnosis.
We
will look at four
major problems here:
i.
Unemployment,
ii.
Inflation,
iii.
Balance of payments problem
and
iv.
The lack of growth.
Because
this is a course in introductory
economics, some of these
problems will have to
be
introduced
in the context of the
economic history of
HICs.
We'll
begin with unemployment,
which, as you know, peaked
during the Great
Depression
leading
to the great rift between
Keynes and the Classicists,
and the subsequent birth of
modern
macroeconomics.
We shall then move to
inflation which became a
major problem in the 1970s
in
the
context of the two oils
price shocks. We'll then
turn to balance of payments
disequilibria
which
have especially afflicted
the LICs since the
early 1980s. Finally we'll
look at the
challenges
involved
in achieving sustainable and
sustained economic
growth.
One
thing you should remember at
all times is that
macroeconomic problems tend to be
related
to
each other, and it is
difficult (and often
misleading) to analyze them in
isolation. It would be
important,
therefore, to see how these
four problems might be
interrelated.
UNEMPLOYMENT
The
History of Unemployment:
The
history of unemployment, which is
relevant to macroeconomics, started
way back in the
Great
Depression (1929-33), when
unemployment rates reached
levels of 25% in the US
and
western
Europe. During the second
world war, the problem
subsided due to
higher
government
defense spending and
war-related recruitment. Post-war,
unemployment rates
continued
to fall as rebuilding efforts
gathered pace all over
the world, esp. in
war-ravaged
Europe
and East Asia. Many colonies
gained independence during
this time as well
(late
1940s
till early 1960s) and
undertook massive infrastructure
and industrial initiatives
which
absorbed
a large part of the
workforce. The problem did
not raise its head
again until the
1970s,
when two oil price
shocks (1973, 1979), and
the associated episodes of
cost-push
inflation
and balance of payments
deficits in many countries
led to a global recession
that was
compounded
in the early 1980s by rising
interest rates (induced by
tight US monetary
policy).
The
world recovered from
recession in the mid-1980s,
and following a brief
recession (that
lasted
till the early 1990s),
saw the rise of the
new economy (i.e., the
age of information
technology)
and a rapid growth in jobs
related thereto. By the turn
of the millennium,
however,
the
new economy bubble had
burst, causing decline in
growth rates in many HICs.
This
decline
was compounded by the events
of September the 11th in the New York
and the
subsequent
"war on terror" started by
the U.S. and its
allies. It is worth noting
that Japan, the
world's
2nd largest economy, has
remained in recession virtually
all through the
1990s.
Interestingly,
there has been a general
rise in the rate of
unemployment in many LICs
(except
East
Asia) over the last
2-3 decades a rise
that has not been
strictly correlated with
global
boom-recession
cycles. The unemployment
problem in these LICs was
seen to assume a
more
permanent nature due to
their high population growth
rates rates that far
outstripped
the
rate of new job-creation in
these economies. Also there
was a loss of jobs in many
of these
107

countries
due to adoption of capital-intensive as
opposed to labour-intensive technologies
in
industrial
production.
Definition
of unemployment:
While
unemployment can be defined in
terms of absolute numbers, in
most cases, it is the
rate
of
unemployment which is quoted
and which enables
cross-country comparisons.
The
unemployment
rate is defined as the ratio
of the no. of unemployed
people divided by the
sum
of
the employed and unemployed
people. A rate of 3-4% is
usually considered low,
10-15%
considered
high, and over 20%
considered extremely high. It is
worth mentioning that
unemployment
figures, because they are
such a sensitive political
issue, are often
under-
stated
by government and over-stated by
opposition groups. In most
LICs, "official"
unemployment
rates are seriously
misleading, and you can
find the government quoting
a
figure
of 5% for unemployment, when
the actual rate is around
20-25%, if not
higher.
The
Concept of Labor Force (
LF):
A
fundamental concept in relation to
the above definition of
unemployment is that of the
labour
force
(LF). The labour force is
essentially the denominator in
the formula for
unemployment
rate.
The labour force includes
all people eligible and
able to work, so excludes
children,
elderly
people, parent(s) busy
raising children, the
handicapped and terminally
ill etc.
Note,
however that there is a
difference between a person
who is able to work and a
person
who
is also willing to accept a
particular job. So, for
instance, a chartered accountant
who is
looking
for a job may be offered
the job of a bus driver,
but he will not accept
that job because
it
is not worthy of his
qualifications, and/or offers a
wage below his reservation
wage. Thus, in
order
to be employed you need to
fulfill two conditions: you
have to be a member of the
labour
force
(LF) and you have to be
willing to accept a particular
job ("AJ"). This distinction
will be
developed
further shortly.
Definitional
Problems with Unemployment
Rate:
Keeping
the AJ and LF distinction
aside for a while, there
can be some other
definitional
problems
with the unemployment rate
that need to be addressed. In
particular, we might
wish
to
see why the unemployment
rate may be reported
as:
a.
Lower than it actually is
(i.e. the severity of the
problem of there being very
few jobs
compared
to workers is under-stated).
There are two
common reasons:
underemployment
and disguised unemployment.
Underemployment refers to
the
situation
when a person is reported as
employed but is actually
only doing a
part-time
job.
Disguised unemployment is a situation
where a person gets a salary
but does not
really
have a job to do, as is
often the case for
excess workers in
government
departments.
b.
Higher than it actually is
(i.e. the severity of the
problem of there being very
few jobs
compared
to workers is over-stated). The
possible reasons here could
be:
i.
The existence of child
labour, i.e. children taking
the jobs that would
otherwise
have
been available to
adults.
ii.
Incompatibility between skills
and jobs, i.e. there
might be a demand for
workers
possessing a certain skill,
but the people who
are seeking jobs do
not
have
that skill and therefore
remain unemployed.
iii.
People doing more that
one job. If a doctor works
in a hospital in the
morning
and
runs his/her clinic at home
in the evening, s/he is
actually doing two
jobs.
Were
s/he to concentrate on his/her
home practice only, the
hospital job would
become
available to some other
doctor.
iv.
Unemployment benefit given by
the state to the unemployed.
This is usually the
case
for the welfare states
(most HICs) where people
can live off rather
well on
unemployment
benefit and therefore choose
to not work. In LICs, where
the
state
does not quite pay
unemployment benefits, the
analogy would be
108

VU
beggary.
Some people would rather
beg on the streets than
work honorably
and
earn their living.
An
important concept related to
unemployment is that of its
duration.
The duration of any
particular
unemployment spell depends on
when the benefits of
accepting a certain job
exceed
the
costs of continuing to searching
for a better job (see
also the section on search
or frictional
unemployment
below). In an aggregate sense,
however, the duration of an
unemployment
episode
in a country depends on the
rate at which people enter
the pool of the
unemployed
(i.e.
become unemployed) and the
rate at which they exit
the pool of the unemployed
(i.e. find
an
acceptable job).
People
entering the unemployed pool
include those
made redundant, sacked,
resigning or
temporarily
laid off. They could
also include those formerly
outside the labour force,
for e.g.:
college
leavers, women returning to
the labour force after
raising children.
People
leaving the unemployed pool
include those
taking new jobs, returning
to old jobs (if
they
had been temporarily
suspended or laid off) They
could also include people
who have
become
disheartened and give up
looking for a job, those
who have reached retirement
age,
or
who temporarily withdraw
from the labour force
(e.g. to raise a family),
those who emigrate
or
die.
Costs
of unemployment:
If
unemployment is voluntary, i.e.
people do not work because
they feel they are
better off
being
unemployed, the costs are
borne essentially by society,
not the individual per
se. The
costs
are:
a.
Output and hence national
income is lower than
potential.
b.
Government loses tax
revenues because of a.
c.
Firms lose revenues as they
could have employed more
workers and produce and
sell
more.
d.
Other workers lose
additional wages that they
might have otherwise been
able to earn
with
higher national
output.
e.
There is a general tendency
for crime and violence to
rise in society as
unemployment
levels
increase.
If
unemployment is involuntary, then
all the above broader
social costs are borne,
but private
individual
costs for the unemployed
individual must also now be
added. These would
include
loss
of personal income, mental
stress due to loss in
self-esteem, worsening of
relationship
with
family or friends.
Causes
of unemployment:
There
are essentially three
schools of thought regarding
the causes of unemployment:
the
Classicist,
Keynesian and Monetarist
schools. However,
before we delve into the
specific
arguments
presented thereby, we must
develop an understanding of how
labour market
equilibrium
is generally struck in an
economy.
Labor
Market Equilibrium:
There
is first the supply side of
labour. As mentioned earlier,
however, a distinction needs
to
be
made between LF and AJ. LF
stands for the size of
the labour force, and is
drawn as an
upward
sloping fairly inelastic
line in wage no. of
workers space. It is drawn as
fairly inelastic
because
the size of labour force
would be expected to be fairly
unresponsive to the wage
rate.
A
badly handicapped or terminally
ill person will not
suddenly decide to join the
labour force
just
because wages went up.
Some people (like parents
looking after kids) however
might still
be
inclined to become members of
the labour force if wages go
up; the reason why
the LF
curve
is not perfectly inelastic
(i.e. vertical).
109
Introduction

The
AJ curve represents those
members of the labour force
which are willing to
accept
suitable
jobs. The AJ curve is
flatter than the LF curve
because job seekers would be
more
willing
to accept jobs in response to a
rise in wages compared to
people who are not
even
members
of the labour force. The AJ
curve is to the left of the
LF curve because there
will
always
be some people in LF who
cannot accept jobs (like
the terminally ill).
However, given a
flatter
AJ and a steeper LF, it is clear
why the horizontal gap
between AJ and LF would
narrow
at
higher wage rates.
The
demand for labour is
generated by firms, government-owned or
private, which need
to
hire
workers to produce goods and
services. The lower the
wage rate, the more
will firms be
willing
to hire workers. Therefore,
the demand curve for
labour, LD, is downward
sloping in
wage
no. of workers
space.
The
intersection of LD and AJ determines
labour market equilibrium,
i.e. the no. of
potential
workers
who will be employed
(N1),
and the wage rate
that they will earn
(w*). The
intersection
of
LD and LF delivers N*, the
maximum possible no. of
workers that can be employed
at a
particular
wage rate. The horizontal
distance between N* and
N1 is
referred to as the
natural
level
of unemployment. When the
horizontal axis measure the
employment rate, the
same
measures
the natural rate of
unemployment. To keep things
simple, we will not
differentiate
between
the two terms and
will use them
interchangeably.
Classical
Views about
unemployment:
The
Classicists viewed unemployment as an
essentially voluntary phenomenon
caused by
wages
that were higher than
the free market level. If
wages were allowed to fall
to the market-
clearing
level, firms' demand for
labour would increase,
removing the initial
unemployment.
Their
main policy prescription was
therefore to remove any
factors (labour unions,
minimum
wage
legislation, unemployment benefit)
that prevented wages from
falling to market-clearing
levels.
The theoretical problems
with this view of
unemployment aside, there
were serious
difficulties
that could be expected in
implementing the above
policy prescription. Unions
were
politically
strong bodies and could
not simply be wished away;
removing the minimum
wage
threshold
would hurt the poorest
workers, whose wages would
now fall below the
threshold.
Similarly,
removing unemployment benefit
was likely to be seen as an
attack on the safety
net
for
the poorest sections of
society.
Keynesian
Views about
Unemployment:
Keynes
located the origins of
unemployment in deficient aggregate
demand. According to him,
if
aggregate
demand could be boosted by
pumping government expenditure,
this would cause
the
demand
for labour to increase as
part of a multiplier effect.
The increased demand would
absorb
the
excess supply of labourers,
thus alleviating the
unemployment problem.
