Abstract
This investigation adopts the Correlated Bivariate Poisson GARCH with Jump and Diffusion Volatility Spillover (CBP-GARCH-JDSV) model to determine whether the Qualified Foreign Institutional Investors (QFIIs) deregulation in Taiwanese stock markets influences normal and abnormal information transmission between stock and exchange rates. Empirical results demonstrated that the diffusion and jump process have significantly correlations and interacted with stock and exchange rates markets following the QFIIs deregulation. Finally, normal information transmission changed bi-directionally across markets and abnormal information supports the asset approach to determining exchange rates. Additionally, estimation results suggest that information transmissions are affected by removal of investment restrictions.The Qualified Foreign Institutional Investors Deregulation Jump Intensity Spillovers CBP-GARCH-JDSV Model
