摘要：We study the impact of changes in the competitors' listings in organic search results on the performance of sponsored search advertisements. Using data from an online retailer's keyword advertising campaign, we measure the impact of organic competition on both click-through rate and conversion rate of sponsored search advertisements. We find that an increase in organic competition leads to a decrease in the click performance of sponsored advertisements. However, organic competition helps the c...

摘要：The information technology (IT) governance literature predominantly explains firms' IT governance choices, but not their strategic consequences. We develop the idea that a firm's IT governance choices induce adeptness at strategically exploiting IT only when they are discriminatingly aligned with its departments' knowledge outside their specialty. Discriminating means that governing the two undertheorized classes of IT assets-apps and infrastructure-requires peripheral knowledge in different d...

摘要：The increasing adoption of product recommendation agents (PRAs) by e-commerce merchants makes it an important area of study for information systems researchers. PRAs are a type of Web personalization technology that provides individual consumers with product recommendations based on their product-related needs and preferences expressed explicitly or implicitly. Whereas extant research mainly assumes that such recommendation technologies are designed to benefit consumers and focuses on the posi...

摘要：Pay-per-click (PPC) is a common pricing model used to pay for ads on the Web and is open to the possibility for click fraud, where clicks are not from a legitimate user. Identifying click fraud is generally done in a three-stage process: the service provider (SP) first classifies clicks as fraudulent or not, then the advertiser does the same with a different technology, and if there is a disagreement, the SP examines further and his conclusions are considered binding. The advertiser pays for c...

摘要：Conspicuous consumption affects anyone who cares about social status; it has intrigued sociologists and economists for more than 100 years. The idea that conspicuous consumption can increase social status, as a form of social capital, has been broadly accepted, yet researchers have not been able to test this effect empirically. In this work, we provide empirical evidence by analyzing the digital footprints of purchases and social interactions in different virtual worlds. We use a multimethod a...

摘要：Recently, several researchers provided overarching macromodels to explain individuals' privacy-related decision making. These macromodels-and almost all of the published privacy-related information systems (IS) studies to date-rely on a covert assumption: responses to external stimuli result in deliberate analyses, which lead to fully informed privacy-related attitudes and behaviors. The most expansive of these macromodels, labeled Antecedents- Privacy Concerns-Outcomes (APCO), reflects this a...

摘要：Consumer review systems have become an important marketing communication tool through which consumers share and learn product information. Although there is abundant evidence that consumer reviews have a significant impact on product sales, the design of consumer review systems and its impact on review outcomes and product sales have not yet been well examined. This paper analyzes firms' review system design and product pricing strategies. We formally model two review system design decisions-w...

摘要：Organizations are setting up online forums to obtain inputs and feedback from key stakeholders, such as employees, customers, and citizens. Examples of such virtual spaces are online policy deliberation forums (OPDFs) initiated by government organizations to garner citizens' views on policy issues. Incorporating the inputs from these forums can result in more inclusive policies for societal benefit. Yet, as with other such forums, a common issue facing OPDFs is the sustainability of participat...

摘要：This paper examines how information technology ( IT) can contribute to value creation in horizontal acquisitions. We propose that acquisition value can be created when an acquirer redeploys its digital resources to its newly acquired businesses and consequently improves their operations. However, not all acquirers are equally capable of redeploying their digital resources. In this study, we propose two enabling factors pertaining to an acquirer's IT resource base: IT extensiveness and IT stand...
