This dissertation abstract and the reflection commentary present the work done by Dr. Lea Stadtler. Comprising four articles, the dissertation explores the challenge of designing successful public–private partnerships (PPPs) for development and contributes to the discourse on partnerships and business engagement in society. Article I adopts the company perspective and develops a conceptual framework for interest alignment in PPPs for development. Based on a theoretical analysis, Article II examines the role that different structures play in handling common design challenges. Articles III and IV are empirical: The former analyzes how partners cope with tensions occurring on the PPP's boundaries, while Article IV explores the roles of broker organizations, which increasingly facilitate the partnering process of PPPs for development. This extended dissertation abstract introduces the dissertation's research focus and summarizes each article's research question, methods, and main findings. The reflection commentary in the appendix discusses the author's views of her dissertation journey as a junior scholar and the research process.
