“…Given the importance of the real exchange rate misalignment, a vast range of theoretical and empirical literature was written on the approaches used to estimate the observed real exchange rate and the equilibrium real exchange rate to capture the magnitude of misalignment (Doroodian et al, 2002;Hallett, 2004;Nabli, 2004;Etta-Nkwelle, 2007;Giannellis, 2007;IMF, 2007;Yajie et al, 2007;Quere et al, 2009). Meanwhile, other studies tried to quantify the impact of the misalignments on either trade flows or economic growth, especially for the less developed countries (Cottani et al, 1990;Razin and Collin, 1997;Bouoiyour, 2005;Toulaboe, 2006).…”
