Phillips Curve - Learn How Employment and Inflation are Related
The natural rate of unemployment is the difference between those who would get a higher rate of inflation, and the fall in unemployment will prove temporary. Category: Economics; Title: Relationship Between Inflation and If unemployment falls below its natural rate, inflation will accelerate and vise- versa . The LRPC. The relationship between inflation rates and unemployment rates is inverse. . If unemployment is below (above) its natural rate, inflation will accelerate.
Rise in self-employment and gig economy, have created new types of jobs. Increased monopsony power of employers, who have kept wage growth low, enabling firms to employ more workers. Harder to claim unemployment benefits.
This suggests the Eurozone has a higher natural rate of unemployment. Rigidity in EU labour markets e. Higher degrees of unionisation resulting in wage rigidity. Generous benefits which lessen the pain of unemployment. The cyclical recessions of the s and s had long lasting effects resulting in more unemployment. However, this does not appear to have affected the UK Growing competition from Asian countries, lead to structural unemployment from increased job competition. Duringthe higher unemployment was partly due to lower rates of economic growth — caused by austerity, and deflationary pressures of the Eurozone single currency.
This is the rate of unemployment consistent with a stable rate of inflation. If you try to reduce unemployment by increasing aggregate demand, then you will get a higher rate of inflation, and the fall in unemployment will prove temporary. NAIRU explained If there is an increase in AD, firms pay higher wages to workers in order to increase in output, this increase in nominal wages encourage workers to supply more labour and therefore unemployment falls.
However, the increase in AD also causes inflation to increase and therefore real wages do not actually increased but remain the same. Later workers realise that the increase in wages was only nominal and not a real increase. Therefore they no longer work overtime. Therefore the supply of labour falls, and unemployment returns to its original or Natural rate of unemployment. It is only possible to reduce unemployment by causing an increase in the rate of inflation.
Thus far, we have been assuming that expected inflation depends on recently observed inflation.
This adaptive expectation is too simplistic to be applicable in all circumstances. Rational expectations assume that people optimally use all the available information, including information about current policies, to forecast the future. Because monetary and fiscal policies influence inflation, expected inflation also depends on the monetary and fiscal policies.
According to rational expectations theory, a change in monetary or fiscal policy will change expectations, and an evaluation of any policy change must incorporate this effect on expectations.
This approach implies that inflation is less inertial than it first appears.
The advocates of rational expectations argue that the SRPC does not accurately represent the options available. We can imagine that a painless disinflation, reducing inflation without causing recession, has two requirements. First, the plan to reduce inflation must be announced before the firms and workers who set wages and prices have formed their expectations.
Second, the firms and workers must believe the announcement; otherwise, they will not revise their expectations of inflation. If these requirements are met, the announcement will immediately shift the short-run trade-off between inflation and unemployment downward, permitting a lower rate of inflation without higher unemployment.
Although the rational expectations theory remains controversial, there is general agreement among economists that expectations of inflation influence the short-run trade-off between inflation and unemployment. Now we discuss how expectations influence inflation. Inflation, Unemployment and the Phillips Curve: Two goals of economic policymakers are low inflation and low unemployment.
Inflation is a situation of continuously rising prices, where there must be continuous exogenous changes either in AD or AS. We first examine possible explanations of inflation within the framework of the comparative static model presented previously.
We then move on to examine a relationship between inflation and unemployment called the Phillips curve. The equilibrium price level and real income are P0 and Y0, respectively, and there are some level of unemployment associated with that real income. To achieve this goal the government carried out expansionary fiscal or monetary policy. However, given the fixed money wage and the rise in prices as a result of the government policy, there is a fall in real wage.
Now the question is: What will happen if workers wish to maintain their real wage? Thus, the efforts to maintain the real wage have resulted in a rise of the money wage and the price level, with no effect whatsoever on employment or real income. It may not take place immediately. There may be lags in the adjustment process. Let us take this analysis a little further.
Inflation and Employment
Assume that the process described above has continued for some time and people began to expect that prices will go on rising in the future. We also assume economy is at Y0, P0 and W0 in Fig. The adjustment in the money wage rate— to maintain real wage—is made on the basis of the expected price level rather than the current price level.
In terms of the current price level this adjustment over-compensates for the rise in prices, so the real wage rises and income and employment fall.
To increase income above Y0 it would require an expansionary policy than before, and the effect on money wages and prices would be greater still. But any continuous increase in AD could have similar effect.
For example, if an inflation starts in the rest of the world and our country is initially in equilibrium at P0, Y0 and W0 as in Fig. This will lead to a rise in prices, income and employment and a fall in real wage. If the money wage is raised to maintain the real wage, prices will rise even further.
Whether this process would continue depends on the rate of inflation in the rest of the world relative to the home economy. The above examples bring out some of the major themes in most current discussion of inflation; expansionary government policy to achieve certain goals, leading to a rise in prices, adjustment to the rise in prices and to the expected rise in prices: Why do wages rise even though there is unemployment?

What determines the formation of expectations? How fast do people adjust their expectation? The first step to approach these questions is to pay more attention to the labour market than we have done so far. We have seen two possibilities in the labour market. In a flexible money wage, there is an unique full-employment equilibrium; in a rigid money wage, there would be some unemployment, depending on the money wage and the price level.
In a world in which information, acquiring skills, and mobility were costless, the assumption of flexible money wages would lead to full-employment and no involuntary unemployment, i. What happens if all these costs are not zero?
Now we would find that, there is always some unemployment in a changing economy. It takes time to find the right job at the right wage; changing patterns of demand for goods in a changing technology require changing demands for particular skills, and it takes time to learn new skills.
It is also costly to move and, therefore, sometimes worthwhile to wait in the expectation that mobility may not be necessary. All the above imply that the concept of full-employment is a very ambiguous one, and not a very sensible one, if taken literally to mean that no one is unemployed. Assume we have flexible money wages.
However, this does not mean that there is no unemployment. Let us assume that, for a given structure of the labour market, unemployment is uf as in Fig. Because there is excess demand for labour, two things may happen. First, that the level of unemployment at this real wage is less than uf.
Second, that because of the excess demand the money wage will rise. With an excess demand for labour a wider range of skills would be demanded and the employer would be willing to substitute available skills for unavailable ones. It is also likely that capital would move to areas where labour is available, thus reducing the cost of labour mobility, and information may also spread more quickly. We shall thus assume that there is an indirect relationship between the excess demand for labour and unemployment.Phillips curve - Inflation - measuring the cost of living - Macroeconomics - Khan Academy
Given the excess demand for labour, money wages will rise, until the equilibrium wage rate is reached. Let us also assume that the rate at which money wages rise depends on the excess demand for labour; the greater the pressure in the labour market the faster is the rate of change of money wages.
We thus have two relationships: Combining these two we get a relationship between unemployment and inflation. This relationship is shown in Fig. The full-employment is represented by uf, where there is no tendency for money wages to change, even though there is some unemployment which is known as natural rate of unemployment.
Any level of unemployment less than uf implies that money wages will rise, because there is an excess demand for labour, and the rate at which they will rise depends on the excess demand for labour.
At any unemployment greater than uf there is an excess supply of labour and money wages are likely to fall, at a rate depending on the size of the excess supply. The relationship shown in Fig. Phillips who first discovered the empirical relationship between the change in wages and employment in the U. So far we have been discussing the relationship between the change in wages and unemployment.
To relate the above discussion to an analysis of inflation we have to postulate some relationship between a change in money wages and a change in prices. There have been various ways in which this has been done, such as, mark up theories of pricing or marginal productivity theory of wage determination. For our purpose it does not matter what is the exact relationship between the change in money wages and a change in prices.
Let us assume that there is a positive relationship between the two. We can then translate Fig. Assume that the government wishes to maintain unemployment at u, less than uf. This is a more complex development of the first theme discussed above in terms of the comparative static model but it does not incorporate the second theme—expectations and adjustment to them.
Expectations and the Phillips Curve: To discuss expectations in the analysis of the Phillips Curve, and to sketch briefly some of the recent developments in this field we start with the labour market again. The real wage depends on two factors, the money wage and the price level. When there is inflation both the money wage and the price level are changing and both are expected to change to some extent. An individual selling his labour receives a money wage offer and he has to assess what is the real wage represented by this offer.
To do this he has to think what the price level could be over the period for which he offered the money wage.
Inflation and Unemployment (With Diagram)
The actual real wage is W0 divided by whatever the price level is expected. We thus have a possibility that the actual real wage may be greater or smaller than the real wage expected by the suppliers of labour on which they base their decision about how much labour to supply.
We shall be interested in the rate of change of the variables and thus. We is the expected change of percentage in real wages. Equation 1 states that, the expected percentage change in real wages is equal to the expected percentage change in money wages minus the expected change in the price level.
