The aim of this paper is to investigate participatory cultural initiatives (PCI) and their impact on communities, cities, and regions. The notion of impact exceeds the notion of outcome insofar, as it includes subjective feelings and joint intuitions. PCIs create material and immaterial outcomes through two crucial inputs: human creativity and human intellectual activity. In particular, a participatory approach to cultural and creative initiatives entails civic engagement and strong support for creating and sharing cultural projects, highlighting the subjective relevance of individual contributions and strengthening the feeling of being socially connected among each other. Hence, we address the following research questions: Who are the stakeholders and how are they impacted by participatory cultural initiatives? Are there distinct performance measurement practices in order to assess the impact? We propose an inductive approach conducting a multiple case study method. Through a sound literature review in the field of PCIs, we explore the constructs with reference to the new institutional approach, the participatory governance debate, and stakeholder-theory. Empirically, we conducted a multiple case study of different selected international initiatives such as: Rome as a City of Film (within the UNESCO network of creative cities), the MuseumsQuartier Vienna, Matera as a European Capital of Culture, and a street art initiative in the Tor Marancia District in Rome. We collected primary data through personal semi-structured interviews with the key stakeholders of each initiative, as well as secondary data through documentary analysis. The participatory approach in culture and creative initiatives is gaining momentum in our society. Notwithstanding a prolific body of knowledge on cultural initiatives, we need more insights on how they can contribute to create value for the society as a whole and how we can account for the results. We propose a comprehensive framework that highlights their value for different stakeholders. The research fosters a deeper understanding of PCIs and their societal impact. It supports professionals, politicians, institutions and citizens who are involved in developing, funding, managing and measuring cultural and creative projects. Finally, this paper contributes to expand the literature on participatory culture.
