Inflation – Unemployment Relationship | Economics Help
The debate of the relationship between inflation and unemployment is mainly unemployment is high, the inflation rate tends to be low, even to be negative. A look at the relationship between inflation and unemployment and Higher unemployment will make it harder for unions and workers to. In the article, A.W. Phillips showed a negative correlation between the rate of unemployment and the rate of inflation – the years with high unemployment.
MundellRobert E. LucasMilton Friedmanand F. Theories based on the Phillips curve suggested that this could not happen, and the curve came under a concerted attack from a group of economists headed by Milton Friedman.
In this he followed eight years after Samuelson and Solow  who wrote "All of our discussion has been phrased in short-run terms, dealing with what might happen in the next few years. It would be wrong, though, to think that our Figure 2 menu that related obtainable price and unemployment behavior will maintain its same shape in the longer run. What we do in a policy way during the next few years might cause it to shift in a definite way. Unemployment would then begin to rise back to its previous level, but now with higher inflation rates.
This result implies that over the longer-run there is no trade-off between inflation and unemployment.

This implication is significant for practical reasons because it implies that central banks should not set unemployment targets below the natural rate. Work by George AkerlofWilliam Dickensand George Perry implies that if inflation is reduced from two to zero percent, unemployment will be permanently increased by 1. This is because workers generally have a higher tolerance for real wage cuts than nominal ones.
For example, a worker will more likely accept a wage increase of two percent when inflation is three percent, than a wage cut of one percent when the inflation rate is zero. Today[ edit ] U. There is no single curve that will fit the data, but there are three rough aggregations——71, —84, and —92—each of which shows a general, downwards slope, but at three very different levels with the shifts occurring abruptly.
The theory goes under several names, with some variation in its details, but all modern versions distinguish between short-run and long-run effects on unemployment. This is because in the short run, there is generally an inverse relationship between inflation and the unemployment rate; as illustrated in the downward sloping short-run Phillips curve.
In the long run, that relationship breaks down and the economy eventually returns to the natural rate of unemployment regardless of the inflation rate. In the long run, this implies that monetary policy cannot affect unemployment, which adjusts back to its " natural rate ", also called the "NAIRU" or "long-run Phillips curve". Higher unemployment will make it harder for unions and workers to bargain for higher wages. This is because if they ask for higher wages, employers can turn round and say there are 3 million unemployed people willing to work at lower wages.
Inflation – Unemployment Relationship
Therefore, wage inflation is likely to be muted during the period of rising unemployment. This will reduce cost push inflation and demand-pull inflation.
The higher unemployment is also a reflection of the decline in economic output. Therefore, firms are seeing an increase in spare capacity and increase in volume goods not sold.
In a recession, there will be greater price competition.
Therefore, the lower output will definitely reduce demand-pull inflation in the economy. Cost-Push Inflation — a worse trade off To complicate the issue, inflation can also be caused by cost-push factors. For example, an increase in oil prices could cause a rise in inflation and a rise in unemployment.
This is because higher oil prices push up costs and reduce disposable income. Therefore, due to cost push factors, the relationship between inflation and unemployment can break down. However, cost-push factors tend to be temporary.
