From previous studies, we include three methodologies namely the GARCH model, the Generalized Method of Moments （GMM） to estimate systems of equations and the Granger causality test to investigate the relationship more thoroughly. In addition, we introduce the lagged volume as a new explanatory variable in the GARCH model. Overall, the results show the significant contemporaneous and dynamic relationships between trading volume and returns volatility which support the sequential information arrival hypothesis and imply some degree of market inefficiency. The results from this study also show that past information of trading volume can be used to improve the prediction of price volatility. Therefore, regulators and traders could include past information of trading volume of SET50 index futures in tracking and monitoring the market volatility level and the investment risk in order to make a timely decision.展开更多

It discusses the case study method and its role and focusing on research questions like healthcare branding, research design, and methodic. Also presents the case study research theory for a research case study. The methods used in this paper are based on hypothesis of a generic hospital branding strategy for the Romanian Private Hospital and also may apply to the Romanian strategy of development of public healthcare entities and partnerships between public and private healthcare entities. An empirical test of the relationships among branding loyalty and awareness, customer satisfaction, trust and relationship commitment suggests that Romanian hospitals can be successful in creating an image and positive brand equity if they can manage their customer relationships well. This can be done through a coordinated strategy of management and marketing development of healthcare entities. The results highlight the dominance of case-study research in qualitative marketing healthcare and highlight the importance of customer relationships in the branding practice of healthcare marketing. It also shows that marketing managers can succeed in creating positive brand equity and image if they can manage relationships with their customers well.展开更多
