ÅA Lundell: Krister Why have countries in different parts of the world preferred different electoral systems? Does context matter when countries choose electoral systems? Specifically, which contextual factors Krister Lundell are decisive? In the present thesis, Krister Lundell explores these Contextual Determinants of Electoral System Choice of Electoral System Determinants Contextual questions from three theoretical perspectives: a rational, a cultural and historical, and an institutional perspective. Contextual Determinants of The results show that although some institutional choices may be influenced by other particular institutions, the overall Electoral System Choice constitutional framework does not determine the choice of electoral systems. The rational perspective also provides a rather A Macro-Comparative Study 1945–2003 weak explanatory model. However, party system transformation from authoritarian one-party rule to competitive politics often results in a replacement of majoritarian systems with proportional or mixed electoral systems.

He did not, of course, have research in mind, but this line might just as well describe the process of writing a doctoral thesis. The road is definitely long, it is filled with curves and sidetracks, and it marks the end of an era. Despite being a rather lonesome passage, it is nonetheless an interesting adventure with lots of challenges and plenty of joy. However, the journey would have been impossible to undertake without the help of many people. I have had the privilege of receiving continuous assistance from several scholars with expert knowledge. First of all, I would like to thank my supervisor throughout this project, Professor Dag Anckar, for providing valuable assistance and for being my chief source of inspiration and encouragement since the beginning of my career. I am deeply thankful to Professor Lauri Karvonen for contributing greatly to this work. Without his immense effort, the thesis would not have been written. I also want to express my gratitude to Professor Carsten Anckar for providing guidance during several phases of the project. I have benefited greatly from his advice, comments and insights. All other colleagues in political science and public administration deserve my gratitude as well. It has been a pleasure to work in such a stimulating and inspiring environment of research as Hus Lindman. The Finland-Swedish Research School has also been of appreciable help over the years. In addition, I would like to thank the pre-examiners of the thesis, Professor Mikko Mattila and Docent Yonhyok Choe. Their valuable and useful comments on the contents of the study facilitated a considerable improvement during the last phase of the project. In addition to intellectual stimulus, I have received financial support from several instances. The national graduate school VAKAVA has provided most of the financing, including a visit to the University of Essex and attendance at the NOPSA conference in Reykjavik. Part of the work has been financed by a research grant from the Research Centre at the Åbo Akademi University Foundation. Other sources of financing are the Department of Political Science at Åbo Akademi University, the Faculty of Economics and Social Sciences at Åbo Akademi University, the Waldemar von Frenckell Foundation, and SNS (Center for Business and Policy Studies) in Sweden. I am very thankful for all the financial support that I have received. There is more to life than research. I would like to thank all my friends for a great private life. I especially thank the best of my friends, Jan-Eric, for (among other things) giving me the opportunity to fulfil myself as a musician, thereby maintaining a meaningful counterbalance to research. In this connection, I also thank Jari and Mikko, the other members of Olympos Mons. I am very grateful to my parents who have always encouraged and supported me in every aspect of life. Last but not least, I would like to thank Kaisa for filling my life with pleasure outside the fascinating world of music and research. Hus Lindman, November 23, 2005 Krister Lundell CONTENTS: 1.
