First-differenced inference for panel factor series

Ipatova, E. & Trapani, L. (2013). First-differenced inference for panel factor series. Economics Letters, 118(2), pp. 364-366. doi: 10.1016/j.econlet.2012.11.026


We complement existing inferential theory for panel factor models by deriving the asymptotics for the first differences of the estimated factors and common components obtained from a non-stationary panel factor model. As an application, we propose an estimator for the long run variance of the common components.
