In this article, we propose a cointegration-based Permanent-Transitory decomposition for nonstationary Dynamic Factor … Models. Our methodology exploits the cointegration relations among the observable variables and assumes they are driven by a …-term stationary one. A Monte Carlo experiment shows that taking into account the cointegration structure in the DFM leads to a much …

theoretical variations and different appropriate estimation procedures, it is found that only for few pollutants can the typical …
