While there is a short-run tradeoff between unemployment and inflation, it has not been observed in the long run. [5] In 1967 and 1968, Friedman and Phelps asserted that the Phillips curve was only applicable in the short run and that, in the long run, inflationary policies would not decrease unemployment.
Okun's law is an empirical relationship. In Okun's original statement of his law, a 2% increase in output corresponds to a 1% decline in the rate of cyclical unemployment; a 0.5% increase in labor force participation; a 0.5% increase in hours worked per employee; and a 1% increase in output per hours worked (labor productivity).
The best study of the inflation-unemployment trade-off finds that an increase in unemployment would reduce inflation by about one-third of 1%. ... or constant 2% inflation per year over the past ...
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]
In 1970, a cup of coffee cost around 25 cents. Today, that 25-cent cup of joe would actually cost around $1.70. The coffee didn't get any better. The price was driven up by the relentless pressure ...
He, together with Edmund Phelps, contended that the trade-off between inflation and unemployment implied by the Phillips curve was only temporary, but not permanent. If politicians tried to exploit it, it would eventually disappear because higher inflation would over time be built into the economic expectations of households and firms.

The non-accelerating inflation rate of unemployment (NAIRU) [1] is a theoretical level of unemployment below which inflation would be expected to rise. [2] It was first introduced as the NIRU (non-inflationary rate of unemployment) by Franco Modigliani and Lucas Papademos in 1975, as an improvement over the "natural rate of unemployment" concept, [3] [4] [5] which was proposed earlier by ...
