Inflation Persistence, the NAIRU, and the Great Recession
研究了2007-2013年大衰退期间通胀下降幅度远小于1979-1985年类似失业率上升时期的原因，发现通胀持续性变化是关键因素，自然失业率自2007年以来上升了近1个百分点。
The rate of inflation fell far less over the period 2007-2013 than in the period 1979-1985 despite similar large increases in the unemployment rate. This paper asks why. Possible explanations include a change in the persistence of inflation, changes in NAIRU, and other shocks. A change in the persistence of inflation, with inflation more anchored in the period 2007-2013 than in the period 1979-1985, is found to be important. The level and change in the NAIRU cannot be precisely estimated, but the data suggest an increase of nearly 1 percentage point since 2007.
