摘要：Live chat tools have emerged as a channel for fostering synchronous communication between sellers and buyers. The role of live chat in the e-commerce environment, however, is largely underexplored. Using granular data from Alibaba, we examine the effect of live chat on consumers' purchase decisions. After controlling for the selection process that customers with high purchase intention are more likely to initiate live chat in the first place, we find that live chat can increase purchase probab...

摘要：Prior works offer compelling evidence that, on the demand side of the market, user-generated online product reviews play a very important role in informing consumers' purchase decisions. On the supply side, however, the interplay between online product reviews and firm strategies is less understood. We build an analytical model that differentiates products based on consumers' preference for tastes (horizontal differentiation) or quality (vertical differentiation) and show that a firm is able t...

摘要：A cloud service agreement entails the provisioning of a required set of virtual infrastructure resources at a specified level of availability to a client. The agreement also lays out the price charged to the client and a penalty to the provider when the assured availability is not met. The availability assurance involves backup resource provisioning, and the provider needs to allocate backups cost-effectively by balancing the resource-provisioning costs with the potential penalty costs. We dev...

摘要：Protecting organizational information is a top priority for most firms. This reality, coupled with the fact that organizational insiders control much of their organizations' valuable information, has led both researchers and practitioners to acknowledge the importance of insiders' behavior for information security. Until recently, researchers have employed only a few theories to understand these influences, and this has generated calls for a broadened theoretical repertoire. Given this opportu...

摘要：Capacity is the maximum short-run output with capital in place under normal operations, and capital investment increases capacity. Excess capacity can be used as an economic strategy for entry deterrence by lowering average costs over a greater range of output, and as an operations strategy by providing value through flexibility to manage demand fluctuations and production disturbances. Our primary focus is to study the way that information technology (IT) can contribute to a strategy of holdi...

摘要：Abundant empirical evidence supports the overall efficacy of social norms as a strategy to induce behavior change. However, very few studies examine how the effect of social norms is differentially manifest across individuals, especially in the contemporary socially connected digital world. We conjecture that the effects of social norms are conditional on an individual's digital social ties and provide new empirical evidence from a randomized field experiment that included more than 7,000 indi...

摘要：Online reviews offer consumers the indirect experience of products through others' consumption evaluations, whereas previews afford them direct experience through product trials. Although conceptual and empirical studies on the business ramifications of online reviews abound, little is known about how online previews moderate the effects of online reviews on sales. To cast light on this issue, the current research investigated the interactive effects of exposure to online previews and reviews ...

摘要：Digital infrastructures are a result of individual yet interdependent systems evolving in relation to each other. In this paper, we identify three processes by which individual systems become embedded into digital infrastructures. First, there are parallel processes, in which systems become embedded independently of each other. Second, there are competitive processes, in which the embeddedness of one system increases at the expense of another. Finally, there are spanning processes, in which br...

摘要：Given the cost of electronic health records (EHRs) to society and hospitals and the heightened concern about breaches of patient information, it is imperative to understand the risks that EHRs and the pursuit of a meaningful use (MU) initiative, apart from actual attestation of MU, may pose to the privacy of patient information. In this study, we examine how the adoption of EHRs and an MU initiative affect the occurrence of breaches of patient information. We also study whether and how EHRs an...

摘要：WeChat, an instant messaging app, is considered a mega app because of its dominance in terms of use among Chinese smartphone users. Little is known, however, about its externality in the broader app market. This work estimates the spillover effects of WeChat on the other top 50 most frequently used apps in China, using users' weekly app usage data. Given the challenge of determining causal inference from observational data, we apply a graphical model and an econometric method to estimate the s...
