I have to say, now this thesis is finally finished, that I have to agree. Yes, this thesis is the result of many years of hard labour, sometimes on the verge of a breakdown. However, I feel it is important to stress here that I experienced this period as a very joyful one. Two important factors accounted for this. First, I experienced the writing of this thesis as an intellectual voyage of discovery. It was great to see the slow progress in the process of writing. The second reason why my PhD-ship became such a pleasant period was because of the wonderful people who I came to meet and who contributed each in their own way to its completion. Without their help and support it may even not have been finished at all. The foremost persons I am very grateful to are my supervisors. In the first place I would like to thank Mary Morgan for accepting me as her PhD student and for letting me work with her. Though the working relation was sometimes complicated due to the geographical separation (Mary gave up her position at the University of Amsterdam and returned to London, about half a year after I started my PhD), I never felt lost and always felt very privileged to work with her. From Mary I learned to look at the bigger picture and not to worry when a case study didn’t seem to fit into my thesis outline. I appreciate the enormous degree of freedom she gave me to pursue my research. In retrospect, I can honestly say that I would not have wanted it in any another way. I am also greatly indebted to Marcel Boumans, my co-supervisor. He streamlined my thought and forced me to think in terms of measurement. In addition, he went through numerous (and undoubtedly boring) earlier versions. I am grateful for the profound comments he made. Without Marcel this work would have been very different. To this sequence I definitely have to add Harro Maas. Not only was he formally my co- supervisor for the period of one year (in 2004, when Marcel Boumans was based at the Netherlands Institute for Advanced Study in the Humanities and Social Sciences in Wassenaar), in practice, he served throughout my whole PhD as my third PhD supervisor. He was always sincerely interested in my research and progress, keen on keeping me to my deadlines, and provided me with helpful advice on many occasions. iii I felt very lucky to work with these three supervisors and my gratitude to them goes beyond words. Their contributions to this thesis are immeasurable. Other members of the Research Group in the History and Methodology of Economics are (or were) Geert Reuten, Mark Blaug, John Davis, Hsiang-Ke Chao, Robert Went, Edith Kuiper, Floris Heukelom, Carla van El, Adrienne van den Bogaard, Eric Schliessler, Maarten Biermans, and Dirk Damsma. They all contributed in some way to this thesis and make me look back to my PhD period with great pleasure. I enjoyed the discussions, the open intellectual climate of the research group and the great literature we read and discussed. Geert Reuten, who inspired me in my undergraduate days, and Hsiang-Ke Chao, with whom I have worked for many years on the same topic and whom never stopped encouraging me, deserve special mentioning. While it is impossible for me, for reasons of space, to mention all staff of the Department of Economics separately here, I would like to thank in particular Robert Helmink and Wilma de Kruijf of the secretariat for their help and support, and Frank Klaassen and Dirk Veestraeten for their company and interesting and entertaining discussions during supper in the university restaurant. A special thanks goes out to my colleagues and students at the Department of European Studies of the University of Amsterdam. The Department provides a friendly academic climate and enabled me to finish the last bits of my thesis. In particular, I like to thank Michael Wintle for his support and comments on an early version of Chapter 2, and Lia Versteegh and Robbert Büthker for their encouragement and co-operation in teaching. Others who need to be thanked are Aico van Vuuren, for his helpful comments and suggestions on Chapter 5 on search models of unemployment, and Massimo Giuliodori, for his comments and discussions on VAR models in Chapter 4.
