“…Using time series econometric methods, the paper finds that the real exchange rate bears long-run cointegrating relation with productivity differential and a demographic variable, namely, the relative size of young dependents cohort. The findings of this paper accord closely with those of previous studies (such as Corbae and Ouliaris, 1991;Lee et al, 2002;Henry and Olekalns, 2002;Darné and Hoarau, 2008) that find that Australia's real exchange rate does not show mean-reversion and economic fundamentals have permanent impact on it. The contribution of this paper is that in addition to productivity bias, it unveils another influence, namely population cohort that has a long-run permanent influence on the real exchange rate.…”
