Stockholm 1991 ~o Josefin ana.9Lmefie FOREWORD Two and a half years have passed and it is time to put down the pen or rather to save and quit. In the course of this inquiry into the nature of technological and social change, I have been through three technologies of writing: an ordinary ballpoint pen, an electric type-writer and finally I entered the micro-electronic age and shifted to a personal computer. If these technological shifts have had any significant, positive or negative, effect upon the quality of the work I cannot tell. They have certainly increased the cost of writing and the willingness to make changes. To a large extent I have changed my way of organizing the work. I have slowly adapted to the methods of word-processing and I have moved towards more and more sophisticated technology, yet when the writing gets difficult I sometimes go back to using the ballpoint pen. The outcome of the study would probably have been slightly different had I stayed with the original technology. I did however choose to wander in the garden of writing technologies and whatever route I would have taken, would have led me to a different end and there would be no path leading back. The result of my endeavour to unravel the secrets of technological and social change has not only been affected by the technology used. A dissertation is a product ofone doctoral student's struggle, which in its tum is a result of the social settings he or she is associated with. Or to use the words of Thomas Merton, "My successes are not my own. The way to them was prepared by others. The fruit of my labours is not my own: for I am preparing the way for the achievements of another. Nor are my failures my own. They may spring from the failures of another, but they are also compensated for by another's achievement." A dissertation is not produced in a vacuum. And during the seven years of seemingly endless struggles a lot of help has been needed, which has been, generously, offered by friends and colleagues. My first thanks must naturally go to my family: my wife Gunilla without whom I would not have started the project in the first place, and my daughters Josefin and Amelie making all these years at least twice as dynamic. I am also deeply grateful to Lena Bjorklund and Staffan Hulten with whom I spent my first critical years as a doctoral student. Innumerous walks through Stockholm with Staffan have enabled ix FOREWORD me to clarify the main points of my work and our continuous discussions have made it impossible to separate my own ideas from his. My four advisors have enthusiastically guided n1e through the process, always encouraging me to proceed further. Professor Lars-Gunnar Mattsson, Stockholm School of Economics, prepared the road for me, provided good working conditions and has continuously been urging me to complete the work. Continuous discussions, debates and disputes with Docent Hakan Hakansson, Uppsala University, have taken me to a point well beyond what I thought possible. Professor Svante Lindqvist, Royal Institute for Technology, introduced me into the gardens of history of technology and he taught me the difference between being a doctoral student and writing the doctoral dissertation. Professor Bengt Stymne, Stockholm School of Economics, helped me clarify my thoughts by persistently raising the impertinent question: What, more specifically is your research question? The Department of Marketing, Distribution and Industry Dynamics and the Economic Research Institute at the Stockholm School of Economics have provided an excellent environment for research and for writing a dissertation. Numerous research seminars and continuous private discussions have left me greatly indebted to several friends and fellow doctoral students: Per Andersson, Ann-Charlotte Edgren, Torbjorn Flink, Claes-Fredrik Helgesson, Susanne Hertz, Staffan Hulten, Dimitrios Ioannidis, Bengt Molleryd, Anna Nyberg, Magnus Soderlund, Lena Wikstrom, Mats Vilgon, Susanne Ostlund and other past and present colleagues at the department. The critique provided by Docent Bo Sellstedt is greatly appreciated. His comments has been most helpful in the completion of the thesis. I have also had the pleasure of working intimately with the 1M-group affiliated to Uppsala University and various discussions with past and present associates of the group, have provided many invaluable insights. I am especially grateful to Jens Laage-Hellman and Alexandra Waluszewski with whom I have had the opportunity to work more closely, in the field of technological change in industrial networks. My dear friend Jan Ottosson at the Department of Economic History at Uppsala University introduced me to social network analysis. The comments on my work provided by him and some of his fellow economic historians at senunar in Uppsala are greatly appreciated. Parts of my work have been conducted at the Center for Economic Policy Research at Stanford University and I am deeply indebted to professor Nathan Rosenberg and professor Paul A. David for conveying the economic historian's view on technological x FOREWORD change. The stay at Stanford University was made possible thanks to generous financial support from the Swedish National Board for Technical Development, L. Frrenkels Stipendiefond and E. Hellstroms Stipendiefond. This thesis would not have been possible had it not been for all the scientists, researchers, public policy makers, and managers in Swedish image processing network generously supplying me with a wealth of information. Financial support from the Swedish National Board for Technical Development and the Swedish Council for Research in the Humanities and Social Sciences, have kept me alive and my study going for all these years. Finally, I am greatly indebted to Rune Castenas, the Director of the Economic Research Institute at Stockholm School of Economics for his incredible ability to identify and solve all kinds of problems and to Lennart Elg, the Swedish National Board for Technical Development, for always believing in me. Bill Harris of Professional Communications Skills at the Stockholm School of Economics helped me with my English. A very special last word of appreciation goes to Lena Wikstrom and Claes-Fredrik Helgesson for proof reading the final manuscript and helping me with some of the figures and tables. The technology used and the social context in which I have worked have led me down a specific path and in writing this thesis, this has made all the difference.
