The NAIRU in Theory and Practice

Laurence Ball and N. Gregory Mankiw

Journal of Economic Perspectives, 2002, vol. 16, issue 4, 115-136

Abstract: This paper discusses the NAIRU--the non-accelerating inflation rate of unemployment. It first considers the role of the NAIRU concept in business cycle theory, arguing that this concept is implicit in any model in which monetary policy influences both inflation and unemployment. The exact value of the NAIRU is hard to measure, however, in part because it changes over time. The paper then discusses why the NAIRU changes and, in particular, why it fell in the United States during the 1990s. The most promising hypothesis is that the decline in the NAIRU is attributable to the acceleration in productivity growth.
