In applying genetic algorithms for optimal performance, this approach, in the forecasting of the RMB/USD real exchange rate from 1994 to 2000, obviously outperforms typical BP Neural Networks and exhibits a higher capacity in regard to nonlinear, time-variablility, and illegibility of the exchange rate.展开更多

Whether China＇s rapid economic growth brought about real exchange rate appreciation between 1975 and 2002 is empirically examined, based on a supply-side model, the Balassa-Semuelson Hypothesis （BSH）. The same test is conducted on Japan, Hong Kong, Korea, Malaysia, Singapore, Thailand, the Philippines, Indonesia and India. Our result indicates that the BSH only exists where the industrial structure has been upgraded and the economy has been successfully transformed from an agricultural economy to a manufacturing economy. Interestingly, China, among those where the BSH does not present, appears to be upgrading its industrial and trade structure. We then try to answer the question of why past rapid growth has no significant relationship with the RMB real exchange rate and what factors are underlying the trend of the RMB real exchange rate. We expect an appreciating trend of RMB real exchange rate in the foreseeable future, presuming that China＇s industrial upgrading process continues and the factors pertaining to the BSH＇s prediction, such as rise of wage rates in both tradables and nontradables, become more significant.展开更多
