WebA common method for testing Granger causality is to regress yon its own lagged values and on lagged values of xand test the null hypothesis that the estimated coefﬁcients on the lagged values of xare jointly zero. Failure to reject the null hypothesis is equivalent to failing to reject the hypothesis that xdoes not Granger-cause y. WebThe model, null and alternative hypotheses presented here are as inDumitrescu and Hurlin (2012). Similarly to the case of panel unit root testing, rejection of the null hypothesis should be interpreted as evidence of the existence of a large enough number of cross-sectional units iin which the null hypothesis is violated (see e.g.Pesaran(2012)). 3.
