摘要：Electronic commerce can improve market efficiency by helping buyers and sellers find and transact with each other across geographic distance. We study the effect of two distinct forms of electronic commerce on market efficiency, which we measure via the existence and exploitation of spatial arbitrage opportunities. Spatial arbitrage represents a more precise measure of market efficiency than does price dispersion, which is typically used, because it accounts for the transaction costs of tradin...

摘要：Information systems (IS) research usually investigates phenomena at one level of analysis at a time. However, complex IS phenomena may be difficult to address from such a single-level perspective. A multilevel perspective offers an alternative means to examine phenomena by simultaneously accounting for multiple levels of analysis. Although useful guidelines for theory development are widely available, they give little specific attention to developing theory that is conceptualized and analyzed ...

摘要：In this paper, we address the challenge faced by ad networks in managing the fading ads (or fads) shown to an end user during a session of a mobile application (app). A fad is an ad that disappears if the user does not interact with it for some length of time. The withdrawn ad could be replaced by another ad. The goal of the ad network is to determine the sequence of fads shown to the user in an ad space to maximize the expected revenue generated over the user's app session. Mobile in-app adve...

摘要：Firms have made extensive use of interorganizational systems (IOSs) to share knowledge and pursue superior joint performance. Contemporary firms are using IOSs to collaborate widely across the value chain and in an ever-expanding geographic landscape. Thus, institutional distance, which is the difference between the firms' respective institutional fields, has become a prominent challenge. In this study, we investigate the extent to which institutional distance affects IOS-enabled knowledge sha...

摘要：Users are increasingly sharing their product interests and experiences with others on e-commercewebsites. For example, users can tag products using their ownwords, and these product tags then serve as navigation cues for other users who want to search for products. Also, socially endorsed information contributors are sometimes highlighted on websites and serve as direct information sources. This study examines the effects of these two distinct social product search cues, product tags and socia...

摘要：Firms, and other agencies, tend to adopt widely used software to gain economic benefits of scale, which can lead to a software monoculture. This can, in turn, involve the risk of correlated computer systems failure as all systems on the network are exposed to the same software-based vulnerabilities. Software diversity has been introduced as a strategy for disrupting such a monoculture and ultimately decreasing the risk of correlated failure. Nevertheless, common vulnerabilities can be shared b...

摘要：Firm participation in open source software (OSS) development is a noteworthy phenomenon and includes two types of firm-participating OSS projects: community founded (developed from an open project) and spinout (spun out from an information technology firm's internal project). OSS project leaders implement quality controls to improve the quality of developed products. They may not be aware that their implementation of quality controls produces a side effect-quality controls signal unobservable ...

摘要：Increasingly, firms across many industries are grappling with the challenge of declining returns to research and development (R&D). In this study, we investigate if and how information technology (IT) can help firms deal with this problem. We theorize that IT systems can help firms to cope with the complexity and inefficiency in managing innovation when R&D investments scale. We explicate the mechanisms through which IT enables firms to cope with the challenges they face when scaling their R&D...
