Notes: Data on counts of news arrivals in Taiwan and U. Similarly, the estimated ARCH effect of Model 4 is weaker than that in Model 1, indicating that the simultaneous consideration of intraday seasonality, public announcements effects, and unexpected volume innovations mitigates the exaggerated ARCH effects of an intraday GARCH model. Since the time span of seasonality is regular in the data studied in this paper, a well-specified GARCH model with exogenous dummy variables allows us to Y. Bollerslev and Ghysels , Gau and Hua and Gau use the periodic GARCH model to capture the repetitive seasonal variations in the volatility by allowing state-dependent ARCH coefficients in the equation of conditional variance. This suggests another possible factors other than macroeconomic news announcements, uncommon-knowledge information and inventory control reflected in the unexpected volume of trading. Taylor, S.
