    Mechanisms to foster Self-Determination on Engagement Platforms - An Online Experiment
    ( 2022-01-04) Lohrenz, Lisa ; Michalke, Simon ; Robra-Bissantz, Susanne ; Lattemann, Christoph
    Engagement platforms (EPs) are an essential technology to enable the sharing and exchanging of services and resources. As an increasing number of industries has been disrupted by EPs, both scholars and practitioners seek understanding on how to design and govern successful EPs. While the initial focus of platform operators was mainly on profit maximization, the interest in securing or increasing user well-being is constantly growing. Design mechanisms that positively influence the three constructs of Self-Determination Theory, autonomy, competence, and relatedness, and thus well-being, have already been identified. In this study we instantiate these mechanisms in a prototype and conduct a scenario-based online experiment with a between-group design to test four hypotheses (n=111). Our results show that autonomy as well as the intention to use increase significantly through mechanisms that foster Self-Determination.

    Leveraging Emergent Social Interactions for Value Co-Creation on Transaction Platforms
    ( 2022-01-04) Schmidt, Rainer ; Kirchner, Kathrin ; Razmerita, Liana
    Transaction platforms supporting the exchange of services and products between actor groups are the foundation of many new business models. Attracting enough actors by propositioning value is crucial for the success of transaction platforms. Therefore, the proper design of value creation mechanisms is a pre-condition to be successful. Initially, the focus of value creation was on network effects, but now the interactions between the actors are being examined more closely. Emergent social interactions (ESI) – are initiated by users on their initiative and are not subject to top-down planning. However, their impact on value creation on transaction platforms has not been researched in depth. Therefore, our paper investigates how emergent social interactions contribute to value co-creation mechanisms on transaction platforms. We apply a Service-Dominant Logic (S-D logic) theoretical lens and create a framework that describes the impact of emergent social interactions on value co-creation. Our framework integrates the moderation of ESI-based value-co-creation by market properties. Based on the framework, platform designers and entrepreneurs can better decide on the design of trans-action platforms in general and the employment of emergent social interactions. Our theoretical contribution paves the way to developing methods for designing transactional platforms using emergent social interactions respecting the context set by market properties.
