This study examines the problem of forecasting an aggregate of cointegrated disaggregates. It first establishes conditions under which forecasts of an aggregate variable obtained from a disaggregate VECM will be equal to those from an aggregate, univariate time series model, and develops a...

This paper reexamines whether producer prices help predict consumer prices, focusing on model stability and the forecasting performance of time-varying parameter models. In bivariate models, producer price inflation consistently Granger-causes consumer price inflation in-sample but fails to...

This paper uses Monte Carlo experiments to examine the small-sample properties of some commonly used tests of equal forecast accuracy. The study pays particular attention to test power, evaluated using both asymptotic and empirical critical values. In addition to evaluating different tests, this...

The level and volatility of survey-based measures of long-term inflation expectations have come down dramatically over the past several decades. To capture these changes in inflation dynamics, we embed both short- and long-term expectations into a medium-scale VAR with stochastic volatility. The...

This study examines the small sample properties of GMM and ML estimators of non-linear models of covariance structure. The study focuses on the properties of parameter estimates and the Hansen (1982) and Newey (1985) model specification test. It use Monte Carlo simulations to consider the...

This paper examines the responses of prices at different stages of production to an explicitly identified demand shock: a monetary policy shock. The frameworks of Christiano, Eichenbaum, and Evans (1994, 1996) and Sims and Zha (1995b) are used to identify the policy shock as the innovation to...

The concept of trend inflation is important in making accurate inflation forecasts. However, there is little consensus on how the trend in inflation should be modeled. While some studies suggest a survey-based measure of long-run inflation expectations as a good empirical proxy for trend...
