We apply recent panel methodology to investigate the relationship between electricity consumption and real GDP for a set of 12 European Union countries using annual data for the period 1970-2004. Recently developed tests for panel unit roots, cointegration in heterogeneous panels and panel...

In the analysis of longitudinal data it is of main interest to investigate the existence of group and individual effects under correlated observations across time. In this paper, we develop a nonparametric two-step procedure that enables us to estimate group effects under a very general form of...
