NAIRU

NAIRU is an acronym for non-accelerating inflation rate of unemployment, and refers to a level of unemployment below which inflation rises. It was first introduced as NIRU (non-inflationary rate of unemployment) by Franco Modigliani and Lucas Papademos in 1975, as an improvement over the " natural rate of unemployment" concept, which was proposed earlier by Milton Friedman.

Monetary policy conducted under the assumption of a NAIRU involves allowing just enough unemployment in the economy to prevent inflation rising above a given target figure. Prices are allowed to increase gradually and some unemployment is tolerated.
