We examine the relationship between inflation and unemployment in the Most of this focus has been directed at establishing whether or not a negative relationship .. To start, we briefly explain a few basic spectral concepts needed for the.
Two other sources of variation in the rate of inflation are inflation expectations and unexpected changes in the supply of goods and services. Inflation expectations play a significant role in the actual level of inflation, because individuals incorporate their inflation expectations when making price-setting decisions or when bargaining for wages. A change in the availability of goods and services used as inputs in the production process e.
The natural rate of unemployment is not immutable and fluctuates alongside changes within the economy. For example, the natural rate of unemployment is affected by changes in the demographics, educational attainment, and work experience of the labor force; institutions e.
Following the recession, the actual unemployment rate remained significantly elevated compared with estimates of the natural rate of unemployment for multiple years. However, the average inflation rate decreased by less than one percentage point during this period despite predictions of negative inflation rates based on the natural rate model.
Likewise, inflation has recently shown no sign of accelerating as unemployment has approached the natural rate. Some economists have used this as evidence to abandon the concept of a natural rate of unemployment in favor of other alternative indicators to explain fluctuations in inflation.
Some researchers have largely upheld the natural rate model while looking at broader changes in the economy and the specific consequences of the recession to explain the modest decrease in inflation after the recession. One potential explanation involves the limited supply of financing available to businesses after the breakdown of the financial sector.
Another explanation cites changes in how inflation expectations are formed following changes in how the Federal Reserve responds to economic shocks and the establishment of an unofficial inflation target.
Others researchers have cited the unprecedented increase in long-term unemployment that followed the recession, which significantly decreased bargaining power among workers.
A falling unemployment rate is gene rally a cause for celebration as more individuals are able to find jobs; however, the current low unemployment rate has been increasingly cited as a reason to begin rolling back expansionary monetary and fiscal policy. After citing "considerable improvement in labor market conditions," in December for the first time in seven years, the Federal Reserve increased its federal funds target rate, reducing the expansionary power of its monetary policy.
So why is the Federal Reserve reducing the amount of stimulus entering the economy when so many people are still looking for work? The answer involves the relationship between the two parts of the Federal Reserve's dual mandate—maximum employment and stable prices.
In general, economists have observed an inverse relationship between the unemployment rate and the inflation rate, i. This trade-off between unemployment and inflation become particularly pronounced i. In response to the financial crisis and subsequent recession, the Federal Reserve began employing expansionary monetary policy to spur economic growth and improve labor market conditions.
Recently, the unemployment rate has fallen to a level consistent with many estimates of the natural rate of unemployment, between 4. This report discusses the relationship between unemployment and inflation, the general economic theory surrounding this topic, the relationship since the financial crisis, and its use in policymaking.
The Phillips Curve A relationship between the unemployment rate and prices was first prominently established in the late s. This early research focused on the relationship between the unemployment rate and the rate of wage inflation. Phillips found that between andthere was a negative relationship between the unemployment rate and the rate of change in wages in the United Kingdom, showing wages tended to grow faster when the unemployment rate was lower, and vice versa.
As the unemployment rate decreases, the supply of unemployed workers decreases, thus employers must offer higher wages to attract additional employees from other firms. This body of research was expanded, shifting the focus from wage growth to changes in the price level more generally.
Inflation is a general increase in the price of goods and services across the economy, or a general decrease in the value of money. Conversely, deflation is a general decrease in the price of goods and services across the economy, or a general increase in the value of money.Employment and Unemployment - Unemployment and Inflation (1/3) - Principles of Macroeconomics
The inflation rate is determined by observing the price of a consistent set of goods and services over time. In general, the two alternative measures of inflation are headline inflation and core inflation. Headline inflation measures the change in prices across a very broad set of goods and services, and core inflation excludes food and energy from the set of goods and services measured.
Core inflation is often used in place of headline inflation due to the volatile nature of the price of food and energy, which are particularly susceptible to supply shocks.
Many interpreted the early research around the Phillips curve to mean that a stable relationship existed between unemployment and inflation. This suggested that policymakers could choose among a schedule of unemployment and inflation rates; in other words, policymakers could achieve and maintain a lower unemployment rate if they were willing to accept a higher inflation rate and vice versa.
This rationale was prominent in the s, and both the Kennedy and Johnson Administrations considered this framework when designing economic policy. These critics claimed that the static relationship between the unemployment rate and inflation could only persist if individuals never adjusted their expectations around inflation, which would be at odds with the fundamental economic principle that individuals act rationally.
But, if individuals adjusted their expectations around inflation, any effort to maintain an unemployment rate below the natural rate of unemployment would result in continually rising inflation, rather than a one-time increase in the inflation rate. This rebuttal to the original Phillips curve model is now commonly known as the natural rate model. The natural rate of unemployment is often referred to as the non-accelerating inflation rate of unemployment NAIRU. When the unemployment rate falls below the natural rate of unemployment, referred to as a negative unemployment gap, the inflation rate is expected to accelerate.
When the unemployment rate exceeds the natural rate of unemployment, referred to as a positive unemployment gap, inflation is expected to decelerate. The natural rate model gained support as s' events showed that the stable tradeoff between unemployment and inflation as suggested by the Phillips curve appeared to break down.
Unemploymentby [author name scrubbed]. The CBO estimates the NAIRU based on the characteristics of jobs and workers in the economy, and the efficiency of the labor market's matching process. The economy is most stable when actual output equals potential output; the economy is said to be in equilibrium because the demand for goods and services is matched by the economy's ability to supply those goods and services. In other words, certain characteristics and features of the economy capital, labor, and technology determine how much the economy can sustainably produce at a given time, but demand for goods and services is what actually determines how much is produced in the economy.
As actual output diverges from potential output, inflation will tend to become less stable. All else equal, when actual output exceeds the economy's potential output, a positive output gap is created, and inflation will tend to accelerate. When actual output is below potential output, a negative output gap is generated, and inflation will tend to decelerate.
Within the natural rate model, the natural rate of unemployment is the level of unemployment consistent with actual output equaling potential output, and therefore stable inflation.
How the Output Gap Impacts the Rate of Inflation During an economic expansion, total demand for goods and services within the economy can grow to exceed the economy's potential output, and a positive output gap is created.
As demand grows, firms rush to increase their output to meet this new demand. In the short term though, firms have limited options to increase their output. It often takes too long to build a new factory, or order and install additional machinery, so instead firms hire additional employees.
As the number of available workers decreases, workers can bargain for higher wages, and firms are willing to pay higher wages to capitalize on the increased demand for their goods and services. However, as wages increase, upward pressure is placed on the price of all goods and services because labor costs make up a large portion of the total cost of goods and services.
Over time, the average price of goods and services rises to reflect the increased cost of wages. The opposite tends to occur when actual output within the economy is lower than the economy's potential output, and a negative output gap is created. During an economic downturn, total demand within the economy shrinks.

In response to decreased demand, firms reduce hiring, or lay off employees, and the unemployment rate rises. As the unemployment rate rises, workers have less bargaining power when seeking higher wages because they become easier to replace.
Thus, we have a higher price level with a higher unemployment rate. This explains the rise in the price level with the rise in the unemployment rate, the phenomenon which was witnessed during the seventies and early eighties in the developed capitalist countries such as the U.
Note that this has been interpreted by some economists as a shift in the Phillips curve and some as demise or collapse of the Phillips curve. Natural Rate Hypothesis and Adaptive Expectations: A second explanation of occurrence of a higher rate of inflation simultaneously with a higher rate of unemployment was provided by Friedman. He challenged the concept of a stable downward- sloping Phillips curve. According to him, though there is a trade-off between rate of inflation and unemployment in the short run, that is, there exists a short-run downward sloping Phillips curve, but it is not stable and it often shifts both leftward and rightward.
He argued that there is no long-run stable trade-off between rates of inflation and unemployment. His view is that the economy is stable in the long run at the natural rate of unemployment and therefore the long-run Phillips curve is a vertical straight line.
He argues that misguided Keynesian expansionary fiscal and monetary policies based on the wrong assumption that a stable Phillips curve exists only result in increasing rate of inflation.
Natural Rate of Unemployment: It is necessary to explain the concept of natural rate of unemployment on which the concept of long-run Phillips curve is based. The natural rate of unemployment is the rate at which in the labour market the current number of unemployed is equal to the number of jobs available. These unemployed workers are unemployed for the frictional and structural reasons, though the equivalent number of jobs is available for them.
For instance, the fresh entrants may spend a good deal of time in searching for the jobs before they are able to find work.
Further, some industries may be registering a decline in their production rendering some workers unemployed, while others may be growing creating new jobs for workers. But the unemployed workers may have to be provided new training and skills before they are deployed in the newly created jobs in the growing industries.
Since the equivalent number of jobs is available for them, full employment is said to prevail even in the presence of this natural rate of unemployment. It is presently believed that 4 to 5 per cent rate of unemployment represents a natural rate of unemployment in the developed countries. Friedman put forward a theory of adaptive expectations according to which people from their expectations on the basis of previous and present rate of inflation, and change or adapt their expectations only when the actual inflation turns out to be different from their expected rate.
The view of Friedman and his follower monetarists is illustrated in Figure To begin with SPC1 is the short-run Phillips curve and the economy is at point A0, on it corresponding to the natural rate of unemployment equal to 5 per cent of labour force.
The location of this point A0 on the short-run Phillips curve depends on the level of aggregate demand. The other assumption we make is that nominal wages have been set on the expectations that 5 per cent rate of inflation will continue in the future.
Now, suppose for some reasons the government adopts expansionary fiscal and monetary policies to raise aggregate demand. The consequent increase in aggregate demand will cause the rate of inflation to rise, say to seven per cent.
Trade off between unemployment and inflation
Given the level of money wage rate which was fixed on the basis that the 5 per cent rate of inflation would continue to occur, the higher price level than expected would raise the profits of the firms which will induce the firms to increase their output and employ more labour.
As a result of the increase in aggregate demand resulting in a higher rate of inflation and more output and employment, the economy will move to point A1 on the short- run Phillips curve SPC1 in Figure It may be noted from Figure Thus, this is in conformity with the concept of Phillips curve explained earlier. However, the advocates of natural rate theory interpret it in a slightly different way.
They think that lower rate of unemployment achieved is only a temporary phenomenon. They think when the actual rate of inflation exceeds the one that is expected, unemployment rate will fall below the natural rate only in the short run. In the long run, the natural rate of unemployment will be restored. This brings us to the concept of long-run Phillips curve, which Friedman and other natural rate theorists have put forward.
According to them, the economy will not remain in a stable equilibrium position at A1. This is because the workers will realize that due to the higher rate of inflation than the expected one, their real wages and incomes have fallen.
The workers will therefore demand higher nominal wages to restore their real income. But as nominal wages rise to compensate for the higher rate of inflation than expected, profits of business firms will fall to their earlier levels.
This reduction in their profit implies that the original motivation that prompted them to expand output and increase employment resulting in lower unemployment rate will no longer be there. That is, with the increase is nominal wages in Figure Further, at point B0, and with the actual present rate of inflation equal to 7 per cent, the workers will now expect this 7 per cent inflation rate to continue in future.
It therefore follows, according to Friedman and other natural rate theorists, that the movement along a Phillips curve SPC is only a temporary or short-run phenomenon. In the long when nominal wages are fully adjusted to the changes in the inflation rate and consequently unemployment rate comes back to its natural level, a new short-run Phillips curve is formed at the higher expected rate of inflation.
However, the above process of reduction in unemployment rate and then its returning to the natural level may continue further. The Government may misjudge the situation and think that 7 per cent rate of inflation is too high and adopt expansionary fiscal and monetary policies to increase aggregate demand and thereby to expand the level of employment. With the new increase in aggregate demand, the price level will rise further with nominal wages lagging behind in the short-run.
As a result, profits of business firms will increase and they will expand output and employment causing the reduction in rate of unemployment and rise in the inflation rate.
After some time, the workers will recognize the fall in their real wages and press for higher normal wages to compensate for the higher rate of inflation than expected. That is, in Figure The process may be repeated again with the result that while in the short run, the unemployment rate falls below the natural rate, in the long run it returns to its natural rate.
But throughout this process the inflation rate continuously goes on rising. On joining points such as A0, B0, C0 corresponding to the given natural rate of unemployment we get a vertical long-run Phillips curve LPC in Figure It is important to remember that adaptive expectations theory has also been applied to explain the reverse process of disinflation, that is, fall in the rate of inflation as well as inflation itself.
Suppose in Figure Now, if a decline in aggregate demand occurs, say as a result of contraction of money supply by the Central Bank of a country, this will reduce inflation rate below the 9 per cent expected rate.
As a result, profits of business firms will decline because the prices will be falling more rapidly than wages. The decline in profits will cause the firms to reduce employment and consequently unemployment rate will rise. Eventually, firms and workers will adjust their expectations and the unemployment rate will return to the natural rate. The process will be repeated and the economy in the long run will slide down along the vertical long-run Phillips curve showing falling rate of inflation at the given natural rate of unemployment.
It follows from above that according to adaptive expectations theory any rate of inflation can occur in the long run with the natural rate of unemployment.
In the end we explain the viewpoint about inflation and unemployment put forward by Rational Expectations Theory which is the cornerstone of recently developed macroeconomic theory, popularly called new classical macroeconomics. This lag in the adjustment of nominal wages to the price level brings about rise in business profits which induces the firms to expand output and employment in the short run and leads to the reduction in unemployment rate below the natural rate.
According to the rational expectations theory, which is another version of natural unemployment rate theory, there is no lag in the adjustment of nominal wages consequent to the rise in price level.
The advocates of this theory further argue that nominal wages are quickly adjusted to any expected changes in the price level so that there does not exist Phillips curve showing trade-off between rates of inflation and unemployment.
According to them, as a result of increase in aggregate demand, there is no reduction in unemployment rate. The rate of inflation resulting from increase in aggregate demand is fully and correctly anticipated by workers and business firms and get completely and quickly incorporated into the wage agreements resulting in higher prices of products.
Thus, it is the price level that rises, the level of real output and employment remaining unchanged at the natural level. Hence, aggregate supply curve according to the rational expectations theory is a vertical straight line at the full-employment level.
Rational expectations theory rests on two basic elements. The second premise of rational expectations theory is that, like the classical economists, it assumes that all product and factor markets are highly competitive.
As a result, wages and product prices are highly flexible and therefore can quickly change upward and downward.

Indeed, the rational expectations theory considers that new information is quickly assimilated i. In this OQ is the level of real national output corresponding to the full employment of labour with a given natural rate of unemployment.
AS is aggregate supply curve at OQ level of real national output. To begin with, AD1 is the aggregate demand curve which intersects the aggregate supply curve AS at point A and determines price level equal to P1. Suppose Government adopts an expansionary monetary policy to increase output and employment.
As a consequence, aggregate demand curve shifts upward to the new position AD2. According to rational expectations theory, people i. Accordingly, workers would press for higher wages and get it granted, businessmen would raise the prices of their products, lenders would hike their rates of interest. All these increases would take place immediately.
It is thus clear that the increase in aggregate demand i.
