NAIRU
（重定向自Accelerationist Hypothesis）
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.
