To my parents Hidup memerlukan pengorbananan.

Pengorbanan memerlukan perjuangan.

Perjuangan menentukan kejayaan.

Kejayaan pula akan menentukan kebahagiaan.

Jangan impikan kejayaan tanpa berusaha mencapainya.

To Az Zahrawaani, Daniel, Danish and Durrah Kejayaan ini dipenuhi dengan seribu macam kemanisan tetapi

untuk mencapainya perlu seribu macam kepahitan.

Kalau tidak kerana semalam kita telah berusaha, bersabar dan

berdoa, belum tentu hari ini kita akan berada di sini.

Acknowledgments

This dissertation is the end of my long and solitary journey to obtain a Ph.D. degree from the University of Groningen, the Netherlands. At the beginning, many colleagues and friends from my home university (Department of Economics, Universiti Putra Malaysia) asked me why I had chosen the University of Groningen for my Ph.D. study.

This may seem a somewhat uncommon destination indeed, because most of the staff members pursue their Ph.D. in economics in the United States, the United Kingdom, or Australia. My answer was simple: “I am looking for a “guru” in input-output analysis.” In addition, the University of Groningen offers a research-based Ph.D.

program which would certainly benefit my home university in its attempt to increase the quality of research and the number of publications. In that respect, I expected to learn a lot in Groningen that could be beneficial for my home university. Another question that I received was: “How is Groningen city?” I had no idea. The only information I had then was about Fandi Ahmad, a Singaporean football player, who played for FC Groningen in the 1990s. After living in Groningen for four years (2006- 2010), I can say that it is a great city to study and live in. Ik hou van Groningen.

This dissertation is a collection of self-contained papers, the drafts of which were written between December 2006 and December 2010 at the Faculty of Economics and Business of the University of Groningen. This dissertation would not have appeared in its present form without the kind assistance and support from many people. It is a true honor and pleasure to acknowledge them here.

It has been a great experience to work under the supervision of two well-known input-output experts, Erik Dietzenbacher and Bart Los. With his enthusiasm, inspiration, and great efforts in explaining things clearly and simply, Erik made input- output analyses fun for me. He has provided excellent guidance from the beginning until the completion of this dissertation. Bart is an enduring source of innovative and critical thinking. He gave me the inspiration to create the novel aspects of my research, which certainly has improved its quality. Both of them have provided extensive efforts in reading and editing drafts of the papers. Apart from the scientific writing experiences that I learned from them, I believe that Erik and Bart have succeeded in transforming me in three aspects: (i) from an unfocused to a focused worker; (ii) from a standard Malaysian researcher to an international researcher; and (iii) from publishing in “local” journals to publishing in social science citation indexed journals. Apart from research guidance, Erik also taught me “how to make life easy”

while Bart trained me “to become a good badminton player”. This additional knowledge sharing has certainly made my life colorful and enjoyable.

I would like to express my gratitude to the members of the assessment committee (beoordelingscommissie), Jan Oosterhaven, Maria Llop and David Roland- Holst for their willingness to read this dissertation. Their valuable comments and suggestions have certainly further improved the quality of this dissertation.

This study would not have been possible without the support and assistance from various government agencies in Malaysia. The financial means provided jointly by Universiti Putra Malaysia and the Ministry of Higher Education Malaysia were crucial for the completion of this study. The strong support from the Economic Planning Unit Malaysia has made this study feasible. Data supply and guidance provided by the Department of Statistics Malaysia have in many ways facilitated my research.

I owe my deepest gratitude to the members of Research School SOM, Martin Land, Rina Koning, Ellen Nienhuis, Arthur de Boer and Astrid Beerta for their legal and administrative support. The assistance of Rina and Ellen in organizing the translation of the dissertation summary in Dutch is highly appreciated.

I am indebted to many colleagues who have read my papers or commented on my presentations in Groningen. Among them are Jan Oosterhaven, Bert Steenge, Dirk Stelder, Marcel Timmer, Dirk Bezemer and Robert Inklaar. Also several colleagues outside Groningen (who I met personally at conferences or virtually via e-mail communication) have provided their valuable comments and suggestions. I have benefited in particular from Jeffery Round, Graham Pyatt, Geoffrey J.D. Hewings, Michael L. Lahr, Gülay Günlük-Şenesen, Kurt Kratena, David L. Ryan, Manuel Frondel and Henry Thompson. Furthermore, it has always been a pleasure to have communications beyond academic discourse with other Ph.D. colleagues: Umed Temurshoev, Xuemei Jiang, Maaike Bouwmeester, Jiansuo Pei, Quanrun Chen, Janneke Pieters, Abdul Azeez Erumban, Gaaitzen de Vries, Lewis Lishemoi, Kadek Dian Sutrisma Artha, Peter van Santen, and Anna Samaryna.

Finally, my heartfelt thanks to my wife, Az Zahrawaani, who has tolerated my inordinate demand for time over the past few years. I think the best way of expressing my gratitude is by dedicating this book to her.
