There are two crucial conditions for cross-sectional aggregation of AR(1) parameters to produce long memory: 1) heterogeneity and 2) proximity to the unit root. We analyze role of moments, namely the mean and variance, of the distribution of the AR(1) coefficients in generating long memory. The...

Extending recent theoretical contributions on sources of inflation inertia, we argue that monetary uncertainty accounts for sluggish expectations adjustment to nominal disturbances. Estimating a model in which rational individuals learn over time about shifts in U.S. monetary policy and the...

This paper examines the determinants of inflation forecast uncertainty using a panel of density forecasts from the Survey of Professional Forecasters (SPF). We show that previous studies based on aggregate data are biased due to heterogeneity of individual forecasts. Instead, we estimate a...

Forecasting inflation remains an intriguing research topic among academics and practitioners alike. Recent studies by Stock and Watson (1999 JME, 2003 JEL) have documented the limited usefulness of Phillip curve type models using unemployment or other macroeconomic and financial variables for...
