Using state-space modeling, we extract information from surveys of long-term inflation expectations and multiple … quarterly inflation series to undertake a real-time decomposition of quarterly headline PCE and GDP-deflator inflation rates … approaches to real-time forecasting of headline PCE inflation. We find that performance is enhanced if forecasting equations are …
