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. [18]
This exhibits a Phillips curve relationship, as inflation is positively related with output (i.e. inflation is negatively related with unemployment). However, and this is the point, the existence of a short-run Phillips curve does not make the central bank capable of exploiting this relationship in a systematic way.
In long-run equilibrium of an industry in which perfect competition prevails, the LRMC = LRAC at the minimum LRAC and associated output. The shape of the long-run marginal and average costs curves is influenced by the type of returns to scale. The long-run is a planning and implementation stage.
The rationale behind Lucas's supply theory centers on how suppliers get information. Lucas claimed that suppliers had to respond to a "signal extraction" problem when making decisions based on prices; the firms had to determine what portion of price changes in their respective industries reflected a general change in nominal prices (inflation) and what portion reflected a change in real prices ...
Milton Friedman argued that a natural rate of inflation followed from the Phillips curve.This showed wages tend to rise when unemployment is low. Friedman argued that inflation was the same as wage rises, and built his argument upon a widely believed idea, that a stable negative relation between inflation and unemployment existed. [11]

[5]: 266 Under the premise that the price level is flexible in the long run, but sticky or even completely fixed under shorter time horizons, it is usual to distinguish between a long-run and a short-run aggregate supply curve. Whereas the long-run aggregate supply curve (LRAS) is vertical, the short-run aggregate supply curve will have a ...
