The sustainability of trade balances in Sub-Saharan Africa: panel cointegration tests with cross-section dependence
This paper investigates the sustainability of trade balances in the Sub-Saharan African regions, using both the panel unit root (IPS) test proposed by Im et al. (2003) and the cross-sectionally augmented version of the IPS (CIPS test) suggested by Pesaran (2007), where the former test is based on the assumption of cross-section independence and the latter allows for it. On the one hand, the empirical results based on the IPS test indicate that the balance of trade in Sub-Saharan African regions is sustainable. On the other hand, the empirical results of the CIPS test reveal that it is not. Since cross-section dependence was recognized using the CD test developed by Pesaran (2004), the empirical results based on the IPS test could be spurious.
