•Agent-based simulation models:To predict complex behavior in OC systems agent-based modeling techniques are crucial. Agent-based models provide theoretical leverage where the global patterns of interest are more than the aggregation of individual attributes, but at the same time, the emergent pat-tern cannot be understood without a bottom up dynamical model of the micro-foundations at the relational level. Re-cently an agent-based model to investigate the performance of OC from a behavioral point of view has been proposed[24]. So far, however, such model has not been validated with em-pirical data and also it needs to be extended in order to cap-ture the sociotechnical and dynamic dimension of OC over time. Recently, one of the founding scholars of the field of computational organizational science has developed a toolkit CONSTRUCT to link meta-models, text mining, network analyt-ics and agent-based modeling[9]. While this toolkit provides novel means to advance to explain and predict complex dif-fusion processes in organizational system, it does not reflect the particular nature of open digital innovation in virtual envi-ronments. Open collaboration often implies non-transitive re-lationships, and is not just shaped by social relationships.
