The aim of this paper is to study the sustainability of current accounts in ECOWAS countries over the 1970–2015 period and test if this sustainability depends on the sub-regional blocs. The paper uses a formal theoretical framework, recent panel and intra-panel cointegration techniques to test...

Using the new unit root test by Phillips et al. (2011) we show that the Target balances of the German Bundesbank have been exploding from the beginning of 2009 to the beginning of 2013. By implementing a full-allotment policy and reducing the required minimum quality of collaterals in October...

We investigate and find evidence for the hysteresis hypothesis in UK imports from South Asian countries, using a monthly sample data that covers 1999 to 2012. This paper finds evidence of the asymmetric effect of exchange rate volatility that "large" depreciations significantly reduce UK imports...

Using a new methodology that allows for nonlinearities, we find frequent support for sustainability in the debt of a set of Latin American countries. Our findings overturn results obtained with traditional unit-root tests and provide a more realistic alternative to evaluate the external solvency...

This paper studies subsampling hypothesis tests for panel data that may be nonstationary, cross-sectionally correlated, and cross-sectionally cointegrated. The subsampling approach provides approximations to the finite sample distributions of the tests without estimating nuisance parameters. The...
