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 The withdrawn ad could be replaced by another ad.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：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：We contribute to the shifting discourse in the literature on information system use, towards context-specific (rather than general) theories and effective use (rather than just use). Organizations are under great pressure to use information systems effectively but they have few theories to turn to for insights. Motivated by this need, we propose an approach for developing context-specific theories of effective use. The approach suggests that effective use can be theorized by: (1) understanding...

摘要：Should a monopolistic vendor adopt the selling model or the leasing model for information goods or services? We study this question in the context of consumer valuation depreciation. Using a two-period game-theoretic model, we consider two types of consumer valuation depreciation for information goods or services: vintage depreciation and individual depreciation. Vintage depreciation assumes that a good or service loses some of its appeal to consumers as it becomes dated, and this effect persi...

摘要：Based on an exploratory multiple-case study in two platform ecosystems, we develop a process theory that explains how and why different ways of practicing ecosystem- wide governance are more or less successful in navigating the tension between cocreated value and governance costs. Our process theory shows that how ecosystem-wide rules and values are practiced considerably varies and changes over time. Initially, governance practices follow ecosystem-wide rules; if and how practices shift towar...

摘要：We empirically examine the impact of expanded product variety on demand concentration using large data sets from the movie rental industry as our test bed. We find that product variety is likely to increase demand concentration, which goes against the long tail effect theory predicting that demand will become less concentrated on hit products because of expanded product variety. We further provide evidence that this finding is not due to introducing many low-selling niche products, as the intu...

摘要：The Internet has presumably created a level playing field that allows any service provider across the globe to compete for contracts on online outsourcing platforms for information technology (IT) services. In this paper, we empirically examine (a) how country (language, time zone, cultural) differences and the country's IT development affect buyers' selection of service providers in online outsourcing platforms; and (b) how the reputation of service providers moderates the proposed effects of...

摘要：This research studies the effect of disconfirmation-the discrepancy between the expected and experienced assessment of the same product-on the behavior of consumers leaving online product reviews. We propose a modeling framework in which an individual's prepurchase expectation is shaped by (1) the product ratings she observes and (2) the perception of the review system she has at the time of the purchase. Upon product consumption, the individual obtains the postpurchase evaluation and encounte...

摘要：We challenge two taken-for-granted assumptions about measurement in positivist research. The first assumption is that measures and measurements are relevant for quantitative, but not qualitative, research. We explain why they apply to both types of research. The second assumption we challenge is that existing measurement practices are unproblematic, even if researchers sometimes vary in how well they enact them. We explain why current norms (both espoused and enacted) are deficient in some imp...

摘要：Our objective in this paper is to explore the impact of information technology (IT) on the performance of open innovation models. We study the effect of IT on the production of patents and product innovations. Our analysis of a large panel of Spanish manufacturing firms confirms that the effect of the proportion of external research and development (R&D) investments on the production of patents and new products has an inverted U-shape. The results also reveal that investments in IT positively ...
