Return threshold model analysis of two stock markets： Evidence study of Italy and Germany＇s stock returns

This paper discusses the model construction and the association between the Italy and the Germany＇s stock markets. The period of study data is from January 3, 2000 to June 30, 2008. This paper also utilizes Student＇s t distribution to analyze the proposed model. The empirical results show that the two stock markets are mutually affected each other, and the dynamic conditional correlation （DCC） and the bivariate asymmetric-GARCH （1, 2） model is appropriate in evaluating the relation between them. The empirical result also indicates that Italy and Germany＇s stock markets show a positive relationship. The average value of correlation coefficient equals to 0.8424, which implies that the two stock markets return volatility have a synchronized influence on each other. In addition, the empirical result also shows that there is an asymmetrical effect between Italy and the Germany＇s stock markets, and demonstrates that the good news and bad news of the stock returns＇ volatility will produce the different variation risks for Italy and the Germany＇s stock price markets.     

An asymmetric and DCC analysis of two stock markets returns＇ volatility： An evidence study on the Hong Kong and Japan＇s stock markets

This paper discusses the model construction and the association between the Hong Kong and the Japanese stock markets. The data period is from January 4, 1999 to December 30, 2005. This paper also utilizes student＇s t distribution to analyze the proposed model. The empirical results show that the bivariate asymmetric-GARCH （1, 2） model with a dynamic conditional correlation （DCC） seemed to be appropriate in evaluating the relationship between them. The empirical result also indicates a positive relation between the Hong Kong and the Japanese stock markets returns. The average estimation value of DCC coefficient equals to 0.5196, which implies that these two stock markets＇ return volatility had synchronized influence on each other. In addition, the empirical results also show that the Hong Kong and the Japanese stock markets have an asymmetrical effect. Based on the idea of the good and bad news, the explanatory ability of proposed model is better than the model of the bivariate GARCH with a DCC.
