Abstract
In this paper we compare two univariate time series models, i.e. one w ith and one without an imposed unit root, in a forecasting experiment for the fourteen annually observed US data analyzed by Nelson and Plos ser (1982, Journal of Monetary Economics 10, 138-162). Our main result is that the unit root mode! is regularly preferred. This result holds for a variety of sample sizes and forecast horizons as well as for on e-step and multi-step ahead forecasts.
