This study represents an empirical analysis of the extent to which China's currency deviates from its long run equilibrium path. The research is based on a cointegrated econometric model of the exchange rate between the Chinese RMB and the American dollar. Using the econometric model, a series of long run equilibrium values for the RMB/USA rate is computed, which is then compared to its historical values in order to derive a time path for extent of disequilibrium.
