Over the past decade there have been increasing calls for alternative ways of tackling poverty problems in developing economies. Rather than aid or charity approaches that have traditionally dominated this area, an alternative line of discussion around base-of-the-pyramid approaches has emerged which emphasizes the role of innovation and pro-poor entrepreneurship. These developments are consequently reshaping our current views on organizational sectors, vulnerable communities, and sources of value creation. First, I would like to express my sincere gratitude and appreciation to my advisor Prof. Dr. Heiko Gebauer for his continuous support and encouragement throughout my Ph.D. journey. His introduction to engaged research will clearly not go unnoticed throughout this thesis. I am also very much indebted to Prof. Dr. Lars Witell, Prof. Dr. Thomas Frandsen, and Dr. Aku Valtakoski for serving on my dissertation committee with their constructive insights that have shaped many views and outcomes embedded in this dissertation. Moreover, much data was collected for this research and many people supported these efforts. My special gratitude thus goes out to the Swiss Agency for Development, the International Water and Sanitation Centre (IRC), and the World Health Organization who have enabled the access to organizations that successfully strive to address sustainable development goals with market-based approaches through a joint and collaborative research program. Aside from other local research assistants, I would especially like to thank Andrea van der Kerk from IRC who accompanied me on multiple field trips. Her international aid research experiences that collided with my Industrial Engineering background were incredibly useful in retrieving and reflecting on field data. In this context, I should probably also thank Dr. med. Thomas Fellmann who advised me to operate a foot injury prior to a lengthy field trip to South East Asia. The crutches were a complete nuisance; yet enabled many delightful and insightful discussions with empathizing case informants. I must also express my deepest gratitude to my mentioned co-authors for their research support, and the interesting related studies they invited me to work on, beyond the scope of this thesis. In this vein, many thanks also go to Prof. Dr. Fisk and his colleagues at the Marketing Faculty of Texas State University, where I gained valuable comments on my research and insights into the importance of social value creation in a variety of other market contexts today. Moreover, I want to express my deep gratitude to my former colleagues at the Environmental Social Sciences division at the Swiss Federal Institute of Aquatic Science and Technology of the ETH who provided a highly intellectually stimulating environment, enriched my epistemological horizons and were a constant cornucopia of invaluable feedback. Furthermore, I must acknowledge the funding sources that made this Ph.D. work possible. Many thanks are due to the Swiss National Science Foundation (SNSF) as well as the...
