ABSTRACTThis paper extends the ‘remarkable property’ of Breusch (Journal of Econometrics 1987; <b>36</b>: 383–389) and Baltagi and Li (Journal of Econometrics 1992; <b>53</b>: 45–51) to the three‐way random components framework. Indeed, like its one‐way and two‐way counterparts, the three‐way random...

An extension of the Holly and Gardiol (2000) and Baltagi et al. (2009) papers to the two way context, with heteroskedastic and spatially correlated disturbances is considered. One then derives a joint LM test for homoskedasticity and no spatial correlation. In addition, two conditional LM tests...

We re-examine the causality between the twin deficits by testing for Granger non-causality between BD and CAD based on extended causality tests initially developed by Toda and Yamamoto (1995). Using international data from a sample of twenty developed and developing countries, we find evidence...
