Outline of Final Research Achievements

The main purpose of this research is to investigate the behavior of dynamic conditional correlations of stock returns of Chinese food related companies in occurrence of offenses against food safety. Two groups of companies are focused: one includes the companies directly related to affairs and the other contains the firms not committing any scandals.
The results show that the degrees of changes in dynamic conditional correlations are smaller compared to the outcomes in Japanese cases found in previous researches.
In addition, an add-on package for the open-source statistical environment R has been developed and published on the Internet for researchers who are interested in conducting similar research topics.
