In this paper we investigate the effect of the outliers on the decomposition of Nelson-Plosser macroeconomic data set into permanent and transitory components from structural time series models. We show that the outliers can disturb the unobserved-components decomposition, especially the variance of trend and cycle innovations, sometimes dramatically.
