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

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

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).

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.
