This study extends the GARCH with autoregressive conditional jump intensity in Generalized Error Distribution (GARJI-GED) model to identify the fundamental characteristics of Nikkei 225 index and futures. Furthermore, this study applied the Granger causality test to investigate whether an...

This article uses parametric and nonparametric Variance Ratio (VR) tests of Lo and Mackinlay (1988) and Wright (2000) to re-examine the weak-form Efficient Market Hypothesis (EMH) for the large- and small-capitalization stock indices of TOPIX (Tokyo Stock Price Index) and FTSE (Financial Times...

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...

This study examines whether nonlinear adjustment of short-term deviations impacts US real estate market returns by applying an exponential smooth transition threshold error-correction model with Generalized Auto Regressive Conditional Heteroscedasticity (GARCH) (ESTECM-GARCH). Empirical results...

This study investigates how foreign investors impact the Taiwanese stock market using the AutoRegressive Jump Intensity (ARJI) model proposed by Chan and Maheu (2002), in which stock volatility in Taiwan is classified as either normal or abnormal and the net purchases of foreign investors,...

Abstract This study investigates the joint phenomena of permanent and transitory components in conditional variance and jump intensity along with verification of structural breaks for crude oil prices. We adopt a Component-ARJI model with structural break analysis, utilizing daily data on West...

This paper uses the traditional variance ratio test of Lo and MacKinlay (1988, 1989), the non-parametric-based variance ratio test of Wright (2000) and the multiple-variance ratio test of Chow and Denning (1993), to re-examine the validity of the weak form efficient market hypothesis for foreign...

This study investigates the impact of the expected and unexpected trading behavior of foreign investors on return volatilities during structural change periods. And the jump intensity model pinpoints crucial events that have influenced the stock market. The empirical results find that there has...

This study utilizes a Smooth Transition Vector Error Correction Model (STVECM) with Glosten-Jagannathan-Runkle-Generalized Autoregressive Conditional Heteroscedasticity (GJR-GARCH) and spillover volatility to investigate the changes in short-run return dynamics when a deviation from the...

This study begins by using a MTAR model to explore the asymmetric effects of error corrections between oil prices in the U.S.A and S&P 500 prices under different regimes. After confirming the lead/lag relationship between the S&P 500 and oil prices, we employ a STECM to analyze the short-run...
