The Phillips curve argues that unemployment and inflation are inversely related: as levels of unemployment decrease, inflation increases. The relationship. But how robust is the relationship between unemployment and inflation in the data? In a recent analysis, economist Olivier Blanchard estimated a Phillips curve . inflation and unemployment; that is, as unemployment decreases, inflation increases. Phillips in his origi- nal article, "The Relationship between Unemployment.
So long as there is discrepancy between the expected rate and the actual rate of inflation, the downward sloping Phillips curve will be found. But when this discrepancy is removed over the long run, the Phillips curve becomes vertical. In order to explain this, Friedman introduces the concept of the natural rate of unemployment. In represents the rate of unemployment at which the economy normally settles because of its structural imperfections.
It is the unemployment rate below which the inflation rate increases, and above which the inflation rate decreases. At this rate, there is neither a tendency for the inflation rate to increase or decrease. Thus the natural rate of unemployment is defined as the rate of unemployment at which the actual rate of inflation equals the expected rate of inflation. It is thus an equilibrium rate of unemployment toward which the economy moves in the long run.
In the long run, the Phillips curve is a vertical line at the natural rate of unemployment. This natural or equilibrium unemployment rate is not fixed for all times.
Rather, it is determined by a number of structural characteristics of the labour and commodity markets within the economy. These may be minimum wage laws, inadequate employment information, deficiencies in manpower training, costs of labour mobility, and other market imperfections.
But what causes the Phillips curve to shift over time is the expected rate of inflation. This refers to the extent the labour correctly forecasts inflation and can adjust wages to the forecast. Suppose the economy is experiencing a mild rate of inflation of 2 per cent and a natural rate of unemployment N of 3 per cent. At point A on the short-run.
Now assume that the government adopts a monetary-fiscal programme to raise aggregate demand in order to lower unemployment from 3 to 2 per cent. The increase in aggregate demand will raise the rate of inflation to 4 per cent consistent with the unemployment rate of 2 per cent.
The Phillips Curve: Relation between Unemployment and Inflation
When the actual inflation rate 4 per cent is greater than the expected inflation rate 2 per centthe economy moves from point A to B along the SPC1 curve and the unemployment rate temporarily falls to 2 per cent. This is achieved because the labour has been deceived. It expected the inflation rate of 2 per cent and based their wage demands on this rate.
But the workers eventually begin to realise that the actual rate of inflation is 4 per cent which now becomes their expected rate of inflation. Now workers demand increase in money wages to meet the higher expected rate of inflation of 4 per cent.
They demand higher wages because they consider the present money wages to be inadequate in real terms. In other words, they want to keep up with higher prices and to eliminate fall in real wages. If the government is determined to maintain the level of unemployment at 2 per cent, it can do so only at the cost of higher rates of inflation.
From point C, unemployment once again can be reduced to 2 per cent via increase in aggregate demand along the SPC2 curve until we arrive at point D. With 2 per cent unemployment and 6 per cent inflation at point D, the expected rate of inflation for workers is 4 per cent.
As soon as they adjust their expectations to the new situation of 6 per cent inflation, the short-run Phillips curve shifts up again to SPC3, and the unemployment will rise back to its natural level of 3 per cent at point E. On this curve, there is no trade-off between unemployment and inflation. Rather, any one of several rates of inflation at points A, C and E is compatible with the natural unemployment rate of 3 per cent. Any reduction in unemployment rate below its natural rate will be associated with an accelerating and ultimately explosive inflation.
But this is only possible temporarily so long as workers overestimate or underestimate the inflation rate. In the long-run, the economy is bound to establish at the natural unemployment rate. There is, therefore, no trade-off between unemployment and inflation except in the short run. This is because inflationary expectations are revised according to what has happened to inflation in the past.
So when the actual rate of inflation, say, rises to 4 per cent in Figure 11, workers continue to expect 2 per cent inflation for a while and only in the long run they revise their expectations upward to 4 per cent. Since they adapt themselves to the expectations, it is called the adaptive exceptions hypothesis. According to this hypothesis, the expected rate of inflation always lags behind the actual rate. But if the actual rate remains constant, the expected rate would ultimately become equal to it.
This leads to the conclusion that a short-run trade off exists between unemployment and inflation, but there is no long run trade-off between the two unless a continuously rising inflation rate is tolerated. The accelerationist hypothesis of Friedman has been criticised on the following grounds: The vertical long-run Phillips curve relates to steady rate of inflation. But this is not a correct view because the economy is always passing through a series of disequilibrium positions with little tendency to approach a steady state.
In such a situation, expectations may be disappointed year after year. Friedman does not give a new theory of how expectations are formed that would be free from theoretical and statistical bias. This makes his position unclear. The vertical long-run Phillips curve implies that all expectations are satisfied and that people correctly anticipate the future inflation rates. Critics point out that people do not anticipate inflation rates correctly, particularly when some prices are almost certain to rise faster than others.
There are bound to be disequilibria between supply and demand caused by uncertainty about the future and that is bound to increase the rate of unemployment. Far from curing unemployment, a dose of inflation is likely to make it worse. In one of his writings Friedman himself accepts the possibility that the long-run Phillips curve might not just be vertical, but could be positively sloped with increasing doses of inflation leading to increasing unemployment.
Some economists have argued that wage rates have not increased at a high rate of unemployment. It is believed that workers have a money illusion. They are more concerned with the increase in their money wage rates than real wage rates. Some economists regard the natural rate of unemployment as a mere abstraction because Friedman has not tried to define it in concrete terms. Saul Hyman has estimated that the long-run Phillips curve is not vertical but is negatively sloped.
According to Hyman, the unemployment rate can be permanently reduced if we are prepared to accept an increase in inflation rate. Without his sincere guidance, this term paper would not have been possible. To understand the relationship of inflation rate and unemployment in India. The main objective of this study is to examine the factors that are responsible for the positive relationship between the unemployment and inflation in India. There is an inverse trade between the rate of unemployment and inflation.
As one increases, the other has to decrease. The idea of Philips curve was proposed by an economist Mr A. He had found that there was a negative relationship between wages and unemployment. Later, inthe economists Paul Samuelson and Robert Solow extended his work by establishing a relationship between unemployment and inflation rates as the largest components of wages are prices.
The past studies have found mixed evidence about the shape of the Phillips curve from being horizontal to vertical. InMilton Friedman asserted that the Phillips Curve was only applicable in the short-run and that in the long-run, inflationary policies will not decrease unemployment. He claimed that Phillips had made three mistakes i he failed to distinguish between nominal wages and real wages ii he ignored temporary and, permanent trade-offs between wage inflation and unemployment rate and iii he did not assign a role to expected inflation.
According to Friedman, there is only one long run, i. Friedman then correctly predicted that, in the upcoming years afterboth inflation and unemployment would increase. Phillips curve involves a disagreement among the investigators about whether unemployment causes inflation or inflation causes unemployment. Fiscal and monetary policies can be used to attain full employment at the cost of high inflation or lower inflation at the cost of high unemployment respectively.
Recently the Federal Reserve has kept the interest rates unchanged citing the low inflation in the US. But shockingly, this relationship has failed in the context of India. Recently, there was news that 23 lakh candidates have applied for the post of peons in Uttar Pradesh. The candidates not only included graduates but also 2.

The study is based on unbalance panel data. The result shows that there is negative relationship between inflation and unemployment rate in SAARC countries. Dholakia, IIM Ahmadabad Julythe study attempts to answer the question whether a tradeoff exists between inflation and unemployment in India. He empirically estimate the Phillips curve for India, subsequently incorporate the extended part of the Phillips curve, and find that a tradeoff does exist in the choice between inflation and unemployment in the short-run in the economy.
The findings show that the conventional Phillips remains absent even on account of controlling for supply shocks, but clearly emerges as he incorporate the extended part into the basic Phillips curve framework.
The results of the extended Phillips curve show that the speed of recovery as captured by the extended part is an important factor in explaining inflation and the strategy for dis-inflation and recovery from adverse supply shocks. Vashist, the study brings out the fact that the past studies have found mixed evidence about the shape of the Phillips curve from being horizontal to vertical.
This shows that any policy aimed at rapid economy growth or recovery will not result in the rise of inflation. Rather it should reduce the involuntary unemployment. While, on the other hand, a slow recovery or lower growth rate may aggravate inflationary tendency in the economy. In sum, it can be said that India can reduce involuntary unemployment through faster and inclusive economic growth without facing the problem of inflation. Muhammad Auwal Abubakar et at. To analyse the objective the research study used ordinary least square method, Augument dickey fuller techniques and Granger causality test.
The study found that the unemployment is positively and significantly effects the wage rate where as inflation rate is affecting the wage rate positively but not significantly.
The result of Unit root revealed that both the variables are stationary. The results of Granger causality test suggests that unemployment Granger causes wage rates but not inflation. Kirandeep Kaur, the study analyse the relationship between unemployment, exchange rate, Growth rate and inflation rate from period with the use of simple linear regression analysis. The study found that there is negative and significant impact of inflation rate and exchange rate on unemployment where as the GDP growth rate effect negatively to unemployment but it is not significant.
The study found that there is trade off between unemployment and inflation but more research work is needed for further analysis of these variables. It has adverse impact on income distribution. A price rise tends to benefit some and harm others. While for some income earners, income rises more rapidly than prices during inflation, for many others just the opposite is true. Those who have fixed incomes are seriously affected as the real income decline during periods of inflation.
Inflation also has an effect on lending and savings. Inflation benefits the borrowers at the expense of the lenders and savers. It has also adverse effects on foreign trade.
What’s the relationship between inflation and unemployment? | Dollars & Sense
The competitiveness of a country may be seriously affected. Factors affecting the inflation 1. Increase in Money Supply: Inflation is caused by an increase in the supply of money which leads to increase in aggregate demand. The higher the growth rate of the nominal money supply, the higher is the rate of inflation. Increase in Disposable Income: When the disposable income of the people increases, it raises their demand for goods and services.
Disposable income may increase with the rise in national income or reduction in taxes or reduction in the saving of the people. Increase in Public Expenditure: Government activities have been expanding much with the result that government expenditure has also been increasing at a phenomenal rate, thereby raising aggregate demand for goods and services 4. Increase in Consumer Spending: The demand for goods and services increases when consumer expenditure increases.
Consumers may spend more due to conspicuous consumption or demonstration effect. Cheap monetary policy or the policy of credit expansion also leads to increase in the money supply which raises the demand for goods and services in the economy 6.
In order to meet its mounting expenses, the government resorts to deficit financing by borrowing from the public and even by printing more notes. Repayment of Public Debt: Whenever the government repays its past internal debt to the public, it leads to increase in the money supply with the public. The existence of black money in all countries due to corruption, tax evasion etc. Shortage of Factors of Production: One of the important causes affecting the supplies of goods is the shortage of such factors as labour, raw materials, power supply, capital, etc.
When the country produces more goods for export than for domestic consumption, this creates shortages of goods in the domestic market.
