This research aims to answer the question ‘What shapes the recruitment of agents for a hybrid institution between politics and administration?’. Theories are a beneficial means to try to find answers to research questions. Those questions that operate with a ‘what’, a ‘how’ or a ‘why’ are harder to answer comprehensively, compared to questions with a ‘where’, ‘when’, or ‘how much’. Theories help to illuminate some aspects of a research question or possible answers to it, but certainly not all.
