This thesis is due to the helpful contributions from supervisors, academic staffs and colleagues I am indebted to Associate Professor Dr Seema W.D Narayan, the senior supervisor, for her intensive supervision I, indeed, appreciate her instruction, suggestions, comments, editing, and care for every steps of this thesis The thesis started with useful research questions and appropriate motivation; however, it was in a difficult to select the best methodology to quantify these questions It was that Professor Dr Seema W.D Narayan has directed me to the relevant methodology amongst alternatives Moreover, I have drwan such important things from her supervision, in which the most important thing is her technique in doing a research I would also thank Dr George Tawadros, the co-supervisor, for his suggestions on the issue of methodology Dr George Tawadros is enthusiastic lecturer to provide feedbacks on the progress of thesis writing I would have great thanks to staffs from the School of Economics, Finance, and Marketing; and the School of Graduate Research for their supports during the whole period of this thesis The success in the milestones of this thesis has been attributed from useful assessment, comments from Dr Ashton de Silva, Associate Professor Dr Heather Mitchell In addition, I especially thank Ms Prue Lamont, Ms Kalpana Lalji, Ms Esther Ng, Ms Claudia Jorquera, and Mr Owen Shemansky for their supports and arrangements association with the administrative procedures I was also having passion in doing the research that has been encouraged from colleagues in School of Economics, Finance, and Marketing I would thank to their shares in studying ii ABBREVIATIONS ADF Augmented Dickey Fuller AFTA ASEAN Free Trade Area APEC Asian Pacific Economic Cooperation ASEAN
