FEER for the CFA franc
Abstract:We investigate the behaviour of the real effective exchange rates (REER) of the two CFA franc zone monetary unions - CEMAC and WAEMU - vis-a-vis their long-run equilibrium paths. A reduced form of the Edwards' (1989) fundamentals equilibrium exchange rate (FEER) model is estimated using the Johansen's (1995) cointegration methodology, and equilibrium paths and associated misalignments are derived for the period 1970 to 2005. Our results suggest that, for both CEMAC and WAEMU, the fundamentals account for most of the exchange rates' fluctuation: increases in the terms-of-trade, government consumption and productivity tend to appreciate the exchange rate, while increases in investment and openness tend to depreciate it. At end of 2005, we find no evidence that either the CEMAC or WAEMU REERs were significantly over-valued, which suggests that no exchange rate action is currently needed. Our analysis also reveals significant differences in the fundamentals' marginal impact, and speed of reversion to equilibrium following a shock, which may raise questions about the desirability of maintaining the same parity for both monetary unions.
