摘要：With the rapid growth of online social network sites (SNSs), it has become imperative for platform owners and online marketers to quantify what factors drive content production on these platforms. Previous research identified challenges in modeling these factors statistically using observational data, where the key difficulty is the inability of conventional methods to disentangle the effects of network formation and network influence on content generation from the subsequent feedback effect o...

摘要：Access to finance is arguably one of the most critical challenges in starting a new business. In this study, we examine how the difficulty of obtaining bank loans based on housing collateral, which is a form of traditional finance, relates to crowdfunding use by entrepreneurs. We obtained data on housing prices related closely to the cost of accessing such bank loans and matched these data to a 2009-2013 novel data set from a leading crowdfunding market. We adopted the first-difference estimat...

摘要：When algorithms use data generated by human beings, they inherit the errors stemming from human biases, which likely diminishes their performance. We examine the design and value of a bias-aware linear classification algorithm that accounts for bias in input data, using breast cancer diagnosis as our specific setting. In this context, a referring physician makes a follow-up recommendation to a patient based on two inputs: the patient's clinical-risk information and the radiologist's mammogram ...

摘要：Senior executives seek investments in information technology (IT) initiatives that enhance the performance of their firms. They frequently must decide whether to emphasize the adoption of new IT (ENIT) or the maintenance and refinement of current IT (ECIT). This research examines how the combination of ENIT and ECIT with the firm's business strategy affects firm performance at varying levels of organizational commitment to IT (OCIT). Using the resource-based view, we argue that a firm can bene...

摘要：Increasingly abundant trace data provide an opportunity for information systems researchers to generate new theory. In this research commentary, we draw on the largely manual tradition of the grounded theory methodology and the highly automated process of computational theory discovery in the sciences to develop a general approach to computationally intensive theory development from trace data. This approach involves the iterative application of four general processes: sampling, synchronic ana...

摘要：In this research, we build a prediction model of movie box office revenue by empirically exploring its intricate relationships with user-generated content (UGC) as well as marketer-generated content (MGC) on a microblogging platform and UGC on a third-party platform. Our analyses are based on a panel vector autoregression (PVAR) model that is calibrated with a combination of data from Weibo (microblogging platform) and Douban! Movies (third party). Our empirical results show that microblogging...

摘要：Managerial responses to online customer reviews not only affect customers who receive the responses but may also influence subsequent customers who observe the responses. This externality arises because of the public nature of online interactions. However, prior studies were mainly in offline settings where such externality rarely exists. In this study, we assess the magnitude of such externality. Using a difference-in-difference-in-differences framework and matched hotels across two large tra...

摘要：Free product sampling has increasingly become a popular promotional strategy and served as a new mechanism of product review generation in e-commerce. We empirically analyze how a product's engagement in free product sampling affects the product's review rating, and we also examine important contingent factors of product pricing and product popularity. Using a rich data set from Taobao. com and multiple identification strategies and estimation methods, we find that engaging in free product sam...

摘要：We investigate the long-term impact of competing against superstars in crowdsourcing contests. Using a unique 50-month longitudinal panel data set on 1677 software design crowdsourcing contests, we illustrate a learning effect where participants are able to improve their skills (learn) more when competing against a superstar than otherwise. We show that an individual's probability of winning in subsequent contests increases significantly more after she has participated in a contest with a supe...

摘要：The 2009 Health Information Technology for Economic and Clinical Health (HITECH) Act is landmark legislation that places electronic health record (EHR) technologies at the center of health system reform in the United States. However, despite their promises, studies in the EHR evaluation literature have found mixed evidence of EHRs' quality benefits. In contrast to existing research that has focused on EHR investments or adoption, we propose that its actual use should be the focus in evaluating...
