主题：Platform Gatekeeping Policy and Knowledge Sharing among Complementors
摘要： Platform owners often emphasize the importance of growing complementor base, yet recent studies have shown that doing so could incur considerable costs. This paper examines how an exogenous deficiency of a gatekeeping policy and the resulted unmanaged growth of complementor base would affect complementor’s off-platform knowledge sharing behaviors, and proposes a gatekeeping policy as an instrument to manage the growth of complementor base. We draw on the literature about platform complementor, the research about platform governance, and the literature on virtual community knowledge sharing to predict that a deficient gatekeeping policy may lead to a drop in complementors’ knowledge sharing efforts, both quantitatively and qualitatively. Using the jailbreak of iOS 7 as an exogenous shock, we find causal evidence that is consistent with our predictions.
