According to Meese's exchange rate model in 1986, in this paper, we modified Meese's (1986) model and suppose the Interest Rate Parity is untenable, the risk premium factor and real exchange rate parameter are considered, and the Purchasing Power parity doesn't follow random walk, we derive our modified equilibrium model. Base on the State Space Model, we try to estimate bubbles and risk premium which are unobservable variables by Kalman Filter to test which one is or both are the main factors that to cause the real assets price biased from the market fundamental price.
