Abstract

This paper proposes a new forecasting method which makes use of information from a
large panel of time series. As in Forni, Hallin, Lippi and Reichlin (2000), and in Stock
and Watson (2002a,b), the method is based on a dynamic factor model. We argue that
our method improves upon a standard principal component predictor in that, first, it fully
exploits all the dynamic covariance structure of the panel and, second, it weights the variables
according to their estimated signal-to-noise ratio. We provide asymptotic results for our
optimal forecast estimator and show that in finite samples our forecast outperforms the
standard principal components predictor.
