摘要：Topic models are becoming a frequently employed tool in the empirical methods repertoire of information systems and management scholars. Given textual corpora, such as consumer reviews and online discussion forums, researchers and business practitioners often use topic modeling to either explore data in an unsupervised fashion or generate variables of interest for subsequent econometric analysis. However, one important concern stems from the fact that topic models can be notorious for their in...

摘要：Software platform ecosystems are emerging as a dominant model for IT-based services. To accelerate third-party development, platform owners often waive restrictions on app user interfaces to provide app developers with more autonomy in interface design. The literature has indicated, however, that standardized interface design across products is a strategic necessity for firms to introduce and manage their product lines, suggesting that platform owners should not waive restrictions on app user ...

摘要：We contribute to the emerging literature on quality certification by digital platforms by studying the launch of the Airbnb Plus service, wherein the platform inspects properties and provides a badge that presumably signals the quality of the property and the reliability of the host. Our identification strategy relies on the fact that the Airbnb Plus service was launched in different cities at different times, and listings within the cities received the certification at different times. Using ...

摘要：While monetary rewards have been widely used by online platforms to motivate user-generated content (UGC) contributions, users may not always demonstrate the expected behaviors. Unintended consequences of reward policies, exemplified by unchanged or reduced UGC contributions, may occur. Through two natural experiments, this study investigates the implications of providing users with an incentive structure that rewards users' continued contribution according to the volume of UGC. Using a unique...

摘要：This study adopts a signaling theory perspective to examine whether and how crowdfunding (relative to angel financing) influences subsequent venture capital (VC) investments in startups. We used a bivariate probit model with propensity score matching to address the potential endogeneity of the initial funding choice. Subsequently, we found that crowdfunded startups have a lower chance of receiving VC funding than angel-financed startups and that the effect is more negative for startups located...
