报告题目：Is the US Phillips Curve Stable? Evidence from Bayesian VARs

报告人：Sune Karlsson, Örebro University Business School

报告摘要：There is a fairly widespread claim that the fall in inflation as the Great Recessionhit the US economy was surprisingly small. We investigate one possible explanation for this, namely that the US Phillips curve is unstable over time and that its slope was lower than usual around the Great Recession. Our study is conducted using Bayesian VARs which are estimated on quarterly data from1990Q1 to 2017Q3. Relying on bivariate models for PCE inflation and the unemployment rate, we assess the importance of time-varying parameters and stochastic volatility. Using new tools for model selection, we find support forboth of these features. We conclude that the Phillips curve has been unstable.Our results also indicate that it may have been somewhat flatter between 2005and 2013 than in the preceding decade. A conditional forecasting exercise suggests that inflation was not unexpectedly high around the Great Recession.
