A Multigeneration Diffusion Model for IT-Intensive Game Consoles

The video game industry has attracted more and more attention not only from technology giants such as Microsoft but also from software developers and private investors. Information technology dictates how game console producers compete in the marketplace. Intensive IT competition in each console generation has shifted the market balance. Competitors jockey to position themselves as the first-mover within a generation or to wait and enter the market with cheaper and more advanced technologies. To capture the characteristics of IT-intensive products, we propose a multigeneration diffusion model that captures both cannibalization and competition effects. We apply the model to analyze game console diffusion with real shipment data for three game consoles from two companies: Sony and Microsoft. We analyze two scenarios: one with only Sony¡¯s products, and one with both companies¡¯ products. We find that the cannibalization between Sony¡¯s products is minimal, and Microsoft maintains a strong competitive edge that has challenged Sony¡¯s market position. The results also explain how Sony has maintained its position as the market leader over the last two generations. This research sheds light on the nature of an IT-intensive game console competition between companies and generations

What habbo goers do in practice? decomposing attitudinal beliefs

We investigate the impact of Information Technology (IT) outsourcing on firm performance from several dimensions, including changes in labor productivity, improvements in financial and operational performance variables, and stock market valuation of IT outsourcing initiatives as measured by Tobin’s q. While our main objective is to better understand the economics of IT outsourcing, we also aim to contribute to the literature on the business value of IT in general. Our research contributes to the relevant literature from the following perspectives: (i) the change in the performance levels of firms due to IT outsourcing is measured against that of firms not outsourcing at all, (ii) panel data regression model is utilized in order to capture both cross-sectional and time-series differences among firms, (iii) the diversity of IT outsourcing initiatives is explicitly considered in the model, and (iv) a comprehensive data set covering the period between 1984 and 2007 is used.

Software Vulnerabilities: Open Source versus Proprietary Software Security

This study seeks to empirically investigate specific security characteristics of both open source software and proprietary software. Operating system software vulnerability data spanning several years are collected and analyzed to determine if significant differences exist in terms of inter-arrival times of published vulnerabilities and patch releases. Open source software is only marginally quicker in releasing patches for reported vulnerabilities. The arguments favoring the inherent security of open source software do not appear to hold up to scrutiny. These findings provide evidence to security managers to focus more on holistic software security management, irrespective of the proprietary-nature of the underlying software

Information Systems and Health Care XII: Toward a Consumer-to-Healthcare Provider (C2H) Electronic Marketplace

Recent technological advances and the heightened expectations of e-health consumers are about to transform the U.S. health care industry. As consumers demand more online services, physicians respond by adopting information technology into their daily routines. In this paper, we first present recent developments within the telemedicine and e-health fields that necessitate the establishment of a consumer-to-healthcare provider (C2H) electronic marketplace. Next, we discuss the services this marketplace should offer to both consumers and physicians for it to thrive in this extensively regulated industry. Finally, we compare these services with those provided by what we call a first-generation C2H marketplace, a comparison that clearly outlines practical implications for the C2H marketplaces of the future

Competition among Experts via Face-to-Face and Online Channels

Online experts increasingly compete against traditional, face-to-face experts by offering many consulting and customer services. In turn, some traditional high-quality experts consider offering online services to defend their markets. In this research, we investigate how a traditional high-quality expert should modify its business model to respond to the new competition arising due to the Internet. We find that the Internet impacts the high-quality traditional expert more adversely than the low-quality traditional expert due to losses in the second opinion market. If the online transaction costs are low, the online expert with an intermediate quality charges a lower price and obtains a higher profit compared to the traditional highquality expert
