|摘要||We employ smooth transition autoregressive (STAR) model to investigate the nonlinear dynamic behavior of gold price, oil price, and the dollar/euro. Results indicate that these variables exist in a nonlinear relationship. We consider the change rate of the dollar/euro as the threshold value that represents the dynamic LSTAR-type process, whereas the oil price as the threshold value represents the smooth symmetric ESTAR-type process. The results present the greater threshold effect that exists between the gold price and
the change rate of the dollar/euro.
