摘要：We examine the effects of human resource management (HRM) practices (e.g., career development, social support, compensation, and security) on information technology (IT) professionals' job search behavior. Job search is a relatively novel dependent variable in studies of voluntary withdrawal behavior in general and for IT professionals in particular. From a universalistic perspective, FIRM practices individually and in combination exhibit independently additive effects on job search behavior. ...

摘要：In this paper we explore the underlying consumer heterogeneity in competitive markets for subscription-based information technology services that exhibit network effects. Insights into consumer heterogeneity with respect to a given service are paramount in forecasting future subscriptions, understanding the impact of price and information dissemination on market penetration growth, and predicting the adoption path for complementary products that target the same customers as the original servic...

摘要：prior work on software release policy implicitly assumes that testing stops at the time of software release. In this research, we propose an alternative release policy for custom-built enterprise-level software projects that allows testing to continue for an additional period after the software product is released. Our analytical results show that the software release policy with postrelease testing has several important advantages over the policy without postrelease testing. First, the total ...

摘要：The existence and persistence of price dispersion for identical products in online markets have been well-documented in the literature. Possible explanations of this price dispersion, derived mainly using hedonic price models, have seen only modest success. In this paper, we propose a competitive model based on online retailers' differentiation mainly in service provided and recognition enjoyed to explain price dispersion. Our exploratory empirical analyses, using cross-sectional data, demonst...

摘要：Organizations are increasingly choosing to implement service-oriented architectures to integrate distributed, loosely coupled applications. These architectures are implemented as services, which typically use XML-based messaging to communicate between service consumers and service providers across enterprise networks. We propose a scheme for caching fragments of service response messages to improve performance and service quality in service-oriented architectures. In our fragment caching schem...

摘要：In this study, we examine how consumers respond to firms' use of two types of information for personalization: product preferences and name. We collect a unique data set of over 10 million e-mail advertisements sent by a website to over 600,000 customers who could buy the advertised products from the online merchant. We estimate a two-stage hierarchical model using Bayesian analysis to account for observable and unobservable consumer heterogeneity. Our analysis suggests several interesting res...

摘要：This paper empirically analyzes the joint effect of switching costs and network effects in determining the level of competition in the European mobile communications industry. Theoretical reasoning argues that switching costs and network effects may confer some market power that firms can strategically exploit to reduce competition and thus increase profits. Theoretical predictions are completely confirmed by the empirical evidence and important asymmetries between the market structures in the...

摘要：Online social media such as blogs are transforming how consumers make consumption decisions, and the music industry is at the forefront of this revolution. Based on data from a leading music blog aggregator, we analyze the relationship between music blogging and full-track sampling, drawing on theories of online social interaction. Our results suggest that intensity of music sampling is positively associated with the popularity of a blog among previous consumers and that this association is st...

摘要：Firms are investing millions to deploy Web-based self-services at their call centers. The rationale for such investment is that the firm's cost of interacting with its customers through the Web-based channel is an order of magnitude cheaper than the assisted channels such as telephony. We conduct a field study at the call center of a prominent U.S. health insurance firm to examine this cost-saving rationale of the Web-based self-service channel. On the one hand, the Web channel may substitute ...

摘要：The Internet has brought consumers increased access to information to make purchase decisions. One of the expected consequences is an increase in the price elasticity of demand, or the percent change in demand caused by a percent change in price, because consumers are better able to compare offerings from multiple suppliers. In this paper, we analyze the impact of the Internet on demand, by comparing the demand functions in the Internet and traditional air travel channels. We use a data set th...
