ItemA Multi-Study Investigation of Service Orchestration in Digital Service Platforms: An Application to P2P Lending Platforms( 2021)Digital service platforms are increasingly important in the economy, given that almost any economic activity can occur online. However, the role and impact of service orchestration, that is, the coordination and facilitation of effective and efficient value cocreating interactions between interdependent economic actors, on digital service platforms is poorly understood. This is problematic because it reveals a limited understanding of effective orchestration mechanisms for facilitating value cocreation; thus, hindering the future development of digital service platforms. This thesis aims to address this gap in knowledge through a multi-study research design. Studies 1 and 2 reconceptualize digital service platforms as complex adaptive systems; therefore, introducing and explaining their currently uninvestigated systemic elements and properties (Chapters 2 and 3). Study 3 introduces agent-based modelling (ABM) as a research method to study digital service platforms as complex adaptive systems (Chapter 4). In particular, this study delineates guidelines for crafting ABM simulations of digital service platforms and demonstrates their application for the peer-to-peer (P2P) lending context. Lastly, Study 4 empirically examines the role and impact of service orchestration on digital service platforms. It defines a typology of orchestration mechanisms displayed by P2P lending platforms and provides insights on the impact of these orchestration mechanisms on actors and on platform performance (Chapter 5). Overall, this thesis offers a broadened theoretical understanding of digital service platforms by providing clearer meaning and scope to a concept that has been theoretically fragmented; therefore, enabling a more comprehensive exploration of their systemic properties and dynamics. This thesis also contributes methodologically by introducing ABMs and demonstrating their applicability for the study of value cocreation in digital service platforms. Lastly, this thesis offers conceptual and empirical insights on the role and impact of service orchestration in P2P lending platforms, which has implications relevant for digital service platforms more broadly.
