In the real world, full employment is just not possible. All economies experience some unemployment accompanied by low standards of living, hardships, psychological distress and mental agony. Side by side with unemployment, most countries are also plagued with inflation and its related consequences. This chapter deals with inflation and also the relationship between the rate of unemployment and the rate of inflation.
A person is unemployed if he is out of work and (1) has been actively looking for work during the previous four weeks, or (2) is waiting to be called back to a job after having been laid off.
A person is unemployed if he is out of work and (1) has been actively looking for work during the previous four weeks, or (2) is waiting to be called back to a job after having been laid off.
A person is employed if during the reference week (1) he did any work (at least one hour) as a paid employee, worked in his own business, profession, or on his own farm, or worked 15 hours or more as an unpaid worker in an enterprise operated by a member of a family, or (2) was not working but had a job or business from which he was temporarily absent, whether or not he was paid for the time off or was seeking another job.
Labour force consists of those people who are unemployed as well as those who are employed.

Labour force consists of those people who are unemployed as well as those who are employed.
Unemployment can be defined more specifically as
Unemployment = Labour Force – Number of people employed
We have, | E = | Total number of employed persons |
U = | Total number of unemployed persons | |
L = | Total labour force |
Using the above notations, we get: L = E = U
Therefore, rate of unemployment
The unemployment pool consists of the number of unemployed persons at any point of time. As more and more people enter the pool, unemployment increases.
Unemployment pool consists of the number of unemployed persons at any point of time.
There are many reasons why a person may become unemployed. Some of them are as follows:
The duration of unemployment is defined as the average length of time for which a person remains unemployed. It indicates whether unemployment is short-term or long-term.
Neither Employed Nor Unemployed: As per the International Labour Organization (ILO) definition, it is quite possible to be neither employed nor unemployed, i.e., to be outside of the “labour force.” The people who belong to this category are those who do not have a job and are not looking for one. Many of these people may be going to college or may be retired. Some may be constrained due to family responsibilities where as others may have a physical or mental disability, which does not allow them to participate in the labour force activities.
The frequency of unemployment is defined as the average number of times, per period, that the workers become unemployed. It depends on two factors:
Frequency of unemployment is defined as the average number of times, per period, that the workers become unemployed.
Natural rate of unemployment is the average rate of unemployment around which any economy fluctuates in the long run. Often it is known as NAIRU (Non-accelerating Inflation Rate of Unemployment). It is calculated as:
Natural rate of unemployment for any year |
= |
Average of unemployment rate for 10 years earlier to ten years later |
Natural rate of unemployment is the average rate of unemployment around which any economy fluctuates in the long run.
The government must formulate policies to reduce the natural rate of unemployment. Some policies in this direction are as follows:
Certainly a Unique Way of Solving Unemployment: Under the ancient system of slave labour, the slave-owners would see to it that their property (the slaves) was never unemployed for long. If anything occurred, they would sell the unemployed labourer rather than keep it unemployed. In the planned economies of the old Soviet Union typically, occupation was provided for everyone, even by overstaffing if it was so required.
Frictional unemployment is the unemployment, which arises due to the time gap it takes for the workers to search for a job that best suits their individual skills and tastes, when the economy is at full-employment. As neither are the workers identical nor are all the jobs identical, it becomes difficult to match the worker’s skills, preferences and their abilities with the job profile. Hence, every economy will have to make do with some extent of frictional unemployment. If frictional unemployment is reduced, then natural rate of unemployment will also fall.
Unemployment in excess of frictional unemployment is what is called cyclical unemployment.
Frictional unemployment is the unemployment, which arises due to the time gap it takes for the workers to search for a job that best suits their individual skills and tastes, when the economy is at full employment.
Wait unemployment is the unemployment, which is caused by wage rigidity above the equilibrium level which in turn results in job rationing.
Wait unemployment is the unemployment, which is caused by wage rigidity above the equilibrium level which, in turn, results in job rationing.
Job rationing occurs when, at the going wage rate, the supply of labour is greater than the demand for labour. The workers are waiting for jobs to be made available to them. The extent of wait unemployment is shown in Figure 21.1.
Figure 21.1 Wait Unemployment
where, | x-axis = Quantity of Labour |
y-axis = Real Wage |
OL = Number of labourers who are willing to take up work
SSL = The supply curve of labour. It is perfectly inelastic at OL units of labour.
DDL = The demand curve for labour. It is downward sloping.
E* = Equilibrium takes place at point E*, where DDL = SSL
OW* = The equilibrium wage rate.
OW1= Let real wage level be rigid at OW1. Here the demand for labour is OL1 and supply of labour is OL. The supply of labour exceeds the demand for labour by L1L. This excess supply of labour leads to wait unemployment. It is called so as L1L units of labour are in the market searching and waiting for jobs.
The Minimum Wage Law, however, may add to the already existing level of unemployment. At the high wages, some workers are laid off due to lack of demand. Thus, there is an increase in the unemployment gap.
An alternative way to increase the income of the poor working class would be, as believed by many economists and policy makers, tax credit. In this scheme, the government makes payment or gives credit to low income families which is more than the tax that they owe to the government.
Minimum Wage Act was passed in India in 1948 and since then has been revised many times. The Act provides for fixation of minimum wages for notified scheduled employment. As per Government of India, for all the States, the minimum wages have been fixed at about Rs. 40 to 60 per day per person, average about Rs. 50 per day for 25 days per month. It has been successful in raising the level of wages for unskilled and some types of semi-skilled workers, thus improving their productive efficiency.
Often, the union aims at maximizing both employment and wage rate. However, given the downward sloping demand curve of labour, a higher wage rate is possible only with a lower level of employment. Hence, this results in a decrease in employment and an increase in wait unemployment.
The costs of unemployment are as follows:
It is very obvious that the unemployed do not produce. Thus, there is a lost output which involves a high cost. Arthur Okun has put forward an empirical relationship between unemployment and output. According to Okun’s law, there is a negative relationship between unemployment and the real GDP.
According to this law, 1 extra point of unemployment costs 2 per cent of the GDP.
Okun’s law is depicted in Figure 21.2 as a downward sloping curve showing an inverse relationship between unemployment and the real GDP.
Figure 21.2 Okun’s Law
The Miseries of the Unemployed: Those who are unemployed are unable to earn money to meet their financial obligations. Thus, they are not in a position to pay mortgage payments or to pay the rent. This may lead them to eviction and without a home. Unemployment also makes one susceptible to malnutrition, mental stress, illness, and loss of self esteem and may even lead to depression. Even the optimistic may find it difficult to remain so in the face of unemployment.
High unemployment can even create a fear of foreigners stealing jobs. Thus, efforts to preserve the existing jobs for the domestic and native workers may lead to barriers against “outsiders” who want jobs, and obstacles to immigration.

y-axis = Real GDP growth rate.
The costs of recession are borne more by those individuals who have lost their jobs. In the less developed countries, the cost of unemployment is the human misery and poverty which the unemployed have to suffer. In the developed countries, people often have a high standard of living. Recession and the consequential unemployment resulting there from have led to high rates of suicides. Left with no work and thus no sources of income, people are increasingly turning towards crimes.
The Phillips’ curve is named after the British economist A. W. Phillips who, in the year 1958, presented a study which was based on the behaviour of wages and their relationship to unemployment, in the United Kingdom for the time period 1861 to 1957.
The Phillips’ curve shows that there exists an inverse relationship or trade-off between the rate of unemployment and the rate of increase in money wages or wage inflation. The higher the rate of unemployment, the lower is the rate of wage inflation.
The rate of wage inflation, gw, can be written as:
where, | gw = the rate of wage inflation |
W = the wage in the current period | |
W–1 = the wage in the preceding period |
Phillips’ curve shows that there exists an inverse relationship or trade-off between the rate of unemployment and the rate of increase in money wages or wage inflation.
Figure 21.3 Phillips’ Curve for the United Kingdom
The natural rate of unemployment is the amount of frictional unemployment that exists at the level of full employment. We denote it by U*. The Phillips curve can be presented as:
gw = –e(U – U*)
where,
e | = | It measures the responsiveness of wages to unemployment |
U | = | the unemployment rate |
U* | = | the natural rate of unemployment |
U – U* | = | the unemployment gap |
From the above equation, the following results emerge:
In Figure 21.3, the original Phillips’ curve has been depicted (for the United Kingdom) as a downward sloping and flat curve showing an inverse relationship between the rate of unemployment and wage inflation.
where, | x-axis = unemployment rate |
y-axis = rate of change in money wage rate |
The original Phillips’ curve shows a negative relationship between the rate of increase in wages and the unemployment rate. Later it came to be described as negative relationship between the rate of increase in prices and the rate of unemployment.
An organized labour market can cause autonomous wage increases, which are in excess of the increases in the productivity of labour. This leads to an increase in the prices of goods, resulting in wage-push inflation.
The extent to which the labour market can push through these increases in wages will vary inversely with the unemployment rate in the labour markets:
Figure 21.4 (a) Labour Market
Figure 21.4 (a) depicts the equilibrium in the labour market.
where, | x-axis = | quantity of labour |
y-axis = | wage rate | |
SSL = | the supply curve of labour | |
DDL = | the demand curve for labour | |
OW* = | Equilibrium wage rate where the demand for labour is equal to the supply of labour. | |
OW1 = | Wage rate at which there is an excess demand for labour equal to EF. | |
OW2 = | Wage rate at which there is an excess demand for labour equal to GH. |
It is quite obvious that when the wage rate is OW1, and the excess demand for labour is EF, the increase in wages will be much greater than with the wage rate OW2 and an excess demand for labour of GH. Thus, the rate of wage increase is inversely related to the amount of excess demand for labour.
This approach can also be expressed in terms of another argument put forward in terms of the Phillips’ curve in Figure 21.4 (b). The amount of unemployment is inversely related to the amount of excess demand for labour.
Figure 21.4 (b) The Phillips’ Curve
Figure 21.4(b) shows
x-axis = unemployment rate
y-axis = rate of change in money wages
OU1 = Unemployment rate at the equilibrium wage rate OW* where the demand for labour is equal to the supply of labour. At this level of unemployment, as there is neither excess demand nor excess supply of labour, the rate of wage increase will be zero. At a wage rate lower than OW*, there will be an excess demand for labour, or in other words, a lower rate of unemployment, and thus a greater increase in the wage rate. This will imply a movement up the Phillips’ curve.
The original Phillips’ curve was unable to explain the behaviour of unemployment and inflation in the United Kingdom and in the United States after the 1960s. Something was missing from it—the concept of expected inflation. The modern Phillips’ curve or the expectations-augmented Phillips’ curve incorporates the concept of expected inflation.
Milton Friedman and Edmund Phelps have argued that the original Phillips’ curve does not take into consideration the effect of expected inflation in the fixation of the wages. Workers are concerned with their real wages and want that their nominal wages should fully take into consideration the inflation they expect. Thus, workers want to be compensated for expected inflation. Firms, on the other hand, are willing to give higher wages because the goods will be sold in the market at higher prices. Thus, when they are fixing wages and prices, firms and workers take into consideration the expected increase in the price level.
Figure 21.5 depicts the modern Phillips’ curve.
where, | x-axis = unemployment rate inflation rate |
y-axis = inflation rate | |
U* = natural rate of unemployment |
Figure 21.5 Modern Phillips’ Curve: Short-run
PC1 and PC2 = These are the short-run modern Phillips’ curves. They are downward sloping and, thus, show a negative relationship between inflation and unemployment in the short-run. The two curves have the same slope showing the same short-run trade-off. However, their height differs because it depends upon the level of expected inflation. The higher the curve higher is the expected inflation for any level of unemployment.
Pont S = It is a point of stagflation. Stagflation is a situation where there is high unemployment and high expected inflation.
Stagflation is a situation where there is high unemployment and high expected inflation.
Economists are of the view that the downward sloping Phillips’ curve implying a trade-off between unemployment and inflation is only a short-run phenomenon. The relationship holds only as long as there is a discrepancy between anticipated and actual inflation rate. Once this discrepancy gets removed, the downward sloping Phillips’ curve and the trade-off thereon no longer exist. Thus, in the long run the Phillips’ curve is vertical, implying that the rate of unemployment is independent of the rate of inflation.
Figure 21.6 depicts the vertical or non trade-off Phillips’ curve.
where,
x-axis = unemployment rate
y-axis = inflation rate
PC1 = initial Phillips’ curve
Point A = Initial point where the rate of unemployment rate is 6 per cent whereas the rate of inflation is 6 per cent.
The government pursues expansionary monetary and fiscal policies, which lead to an increase in aggregate demand. This creates an upward pressure on the rate of inflation, which increases to 8 per cent. The real wage rates experience a decline. This provides an incentive to producers to expand output. This, in turn, leads to an expansion in employment. Over a period of time, the unemployment rate falls and there is a movement upwards along PC1 to point B.
Point B = The point at which there is an unemployment rate of 4 per cent and inflation rate of 8 per cent. It is reached due to the expansionary monetary and fiscal policies and thus leads to the conventional conclusion of a trade-off between the unemployment rate and inflation rate.
Figure 21.6 Modern Phillips’ Curve: Long Run
However, this trade-off is just a temporary phenomenon. Workers do not take long to realize that inflation has caused a reduction in their real wages. Hence, they demand higher money wages. Once the employers accede to their demands, the real wage rate soon returns to its original level. Due to these adjustments, the Phillips’ curve will shift upward and the unemployment rate will increase and come to its original level of 6 per cent.
PC2 = The Phillips’ curve after the impact of the monetary and fiscal policies.
Point C = The point at which there is an unemployment rate of 6 per cent and inflation rate of 8 per cent. It is thus showing that the unemployment rate has returned to its original position. Hence, there is now a situation of higher rate of inflation and higher rate of increase in the money wages and an unemployment rate which has not changed from its original 6 per cent rate.
Further expansionary monetary and fiscal policies will lead to movements from C to D, which is quite similar to the movement from A to B. But ultimately the unemployment rate will once again be at 6 per cent while the rate of inflation will rise further.
Thus, the conventional conclusion of a trade-off between the unemployment rate and inflation rate does not hold in the long run. The actual unemployment rate has a tendency to ultimately gravitate towards the equilibrium rate of unemployment, which Friedman calls the natural rate of unemployment, at which the demand for labour is equal to the supply of labour. The long-run Phillips’ curve becomes vertical at 6 per cent, the natural unemployment rate.
Of the many goals that every economic policy aims at achieving, two goals—low inflation and low unemployment—seem to be conflicting. Hence, there is a trade-off between the two goals of low inflation and low unemployment.
According to the Phillips’ curve, policy makers could make a choice between different combinations of the rate of inflation and the rate of unemployment. They could have low inflation but at the cost of high unemployment, or they could maintain low unemployment but only at the cost of a high inflation.
But it has been found that empirical evidence for most of the countries goes against the findings shown by the Phillips’ curve. It seems that even if there is a trade-off, it exists only in the short-run. There is no permanent inflation–unemployment tradeoff, and the policy makers can make a choice between different combinations of unemployment and inflation.
The sacrifice ratio is the percentage of output, which is lost for a one point decrease in the inflation rate. This ratio also depends on the time, place and methods which are used to reduce the inflation. Available estimates show a sacrifice ratio ranging from 1 to 10. Thus in the short-run, the government can reduce inflation but only at the cost of increasing the unemployment and reducing the level of output. Hence, the cost in terms of output of reducing inflation is very high.
Sacrifice ratio is the percentage of output, which is lost for a 1 point decrease in the inflation rate.
A Short-term Solution But Long-run Problem: A structural solution to unemployment could be in the form of a graduated retail tax, or “jobs levy”, on the firms in which labour is more expensive than capital. This will shift the burden of the tax to capital intensive firms and away from the labour intensive firms. Theoretically, this will make the firms shift their operations to a more desired balance between capital intensive and labour intensive production. The tax revenue from the jobs levy could be used to finance the labour intensive public projects. However, the other side of the coin is that this would certainly discourage capital investment and thus economic growth. With less economic growth, long-run employment would be adversely affected. Hence, this would be just a very short-term solution to the problem.
As already mentioned, the Okun’s law shows that there is a negative relationship between unemployment and the real GDP.
To be more specific, 1 extra point of unemployment costs 2 per cent of GDP.
In the real world, full employment is just not possible. Side by side with unemployment, most countries are also plagued with inflation.
Knowledge of the following terms is necessary:
The costs of unemployment are: a loss in production as depicted by Okun’s law and an undesirable effect on the distribution of income.
The modern Phillips’ curve or the expectations augmented Phillips’ curve incorporates the concept of expected inflation.
The sacrifice ratio is the percentage of output, which is lost for a one point decrease in the inflation rate.
