Furthermore, by using one of the newly developed time dependent nonlinear unit root tests, we find evidence of the fast adjustment to the equilibrium of China's relevant data.

Besides, the current account sustainability of India and Russia can be provided by using state dependent nonlinearity and time and state dependent nonlinearity simultaneously, respectively. The study empirically shows that the current account sustainability for BRICS cannot be provided without taking into consideration the time dependent nonlinearity (i.e.

For this purpose, a linear and a variety of nonlinear unit root tests have been applied to the current account to GDP ratios of the aforementioned countries. This study investigates the current account sustainability hypothesis for Brazil, Russia, India, China and South Africa (BRICS).
