The personal computer (PC) marketplace in the US presents a dizzying array of component suppliers and products. No single firm dominates the industry with a complete package of hardware and software components. Although one company's operating systems and general-purpose applications are installed on most PCs in the US, the other system components—processors, memory, storage devices, display adapters, monitors, specialized applications, and so on—come from any number of sources. David T. Methe, Ryoko Toyama, and Junichiro Miyabe point out that the PC industry in Japan also exhibits this decentralized nature. However, they also note that despite the decentralized network structure of the Japanese PC industry, one company—NEC—was able to achieve a dominant market share. To provide insight into the key issues involved in the management of complex technology, they contrast NEC's strategic approach to product development and organizational learning with the approaches taken by Fujitsu—the firm that placed a distant second in this market. Despite matching NEC in terms of technological capabilities, financial resources, and managerial talent, Fujitsu never managed to threaten NEC's dominance of the PC market in Japan. Fujitsu continually emphasized technological leadership, even at the expense of protecting its installed base. Poor coordination of resources and product development efforts resulted in incompatibilities among Fujitsu's various products, and the company failed to foster close relationships with suppliers of such key technologies as software and peripherals. NEC's PCs did not enjoy the advantages of first-to-market status or technological leadership. Instead, NEC achieved market dominance by finding the combination of product technologies that met the needs of the greatest number of consumers. Throughout almost 20 years of competition in the PC industry, NEC successfully maintained consistency and backward compatibility across its product lines. NEC also recognized the importance of third-party software developers, and carefully cultivated relations with these firms as a source of competitive advantage. In other words, NEC struck the right balance between three key factors: technological innovation, motivation of third-party developers of software and peripherals, and service to its installed base of customers. 相似文献

Two readings are made of Mynatt, Omundson, Schroeder and Stevens (pp. 657–683). The first reading views the paper through a largely “conventional” social science lens, while the second adopts a more critical perspective which raises three issues: abstraction in research; gender and ethnicity; and the rhetoric of research. 相似文献

In this comment we identify the key features of the Frantz and Walker (1997) game theoretic model that drive the non-disclosure equilibrium result in their paper. We argue that, although technically correct, their model fails to capture certain aspects of real-world wage bargaining that will be important in determining optimal disclosure strategies in practice. However, Frantz and Walker's paper illustrates the potential of analytical techniques to contribute to the employee disclosure debate. 相似文献

Over the past decade central governments of the UK, Sweden and Australia have been engaged in significant reforms in the way they pay their employees. These reforms have generally taken the form of the decentralization of pay bargaining and the individualization of pay. This paper details the policies that have been implemented in central government in these countries and presents some preliminary results on the effects of these. While the actual implementation has varied quite substantially across the countries and the analysis of the outcomes must be regarded as preliminary, there is some evidence that the reforms have led to an increase in earnings dispersion. 相似文献

As developing countries search for ways to promote capital formation through the establishment of organized exchanges, they will need to pay more attention to the role of risk management in the securities settlement process. The delivery-versus-payment (DVP) agents that facilitate the process of exchanging securities for funds in most world markets have both the incentive and comparative informational advantage to monitor, measure, and manage risks inherent in the securities settlement system.
Unfortunately, most DVP agents have accomplished this task to date through the cumbersome use of position and net debit limits, capital requirements, and collateral requirements. Such limits and requirements are almost everywhere based on relatively arbitrary criteria that may have no relation to the actual replacement cost, principal, or liquidity risk of the transaction, portfolio, or participant on which they are imposed.
To remedy this shortcoming in the current state of risk management at DVP agents, this article holds out the possibility of integrated, comprehensive risk management processes that emphasize and rely on forward-looking measures of risk for individual brokers and across brokers. Many risk measures could serve the settlement agent's purposes, including "value at risk" (or "VaR"), "below target risk,""below-target probability," and "downside semi-variance." The actual summary risk measure used for risk monitoring and control is not as important as the methodology used to generate that risk measure. "The goal of such a process," as the authors put it, "is to ensure that the risks to which a settlement agent and its residual claimants are exposed are those risks to which the agent's shareholders think they are and want to be exposed." 相似文献

This paper employed eleven data series which consist of stocks, bonds, bills, equity premiums, term premiums, and various default premiums to investigate whether January seasonality reported in existing literature is robust across different states of the economy as this has important trading implications. For the periods 1926–1990, small stocks, small stock premiums, low grade bonds, and default premiums (spread between high grade, low grade and government bonds) reveal January seasonality and that the seasonality is robust across different states of the economy except for low grade bond returns and default premiums. January seasonality for low grade bond returns and low grade bond default premiums are primarily driven by results found during periods of economic expansion. Overall, January seasonality is more evident during the economic expansion periods although the magnitude of default premiums is larger during periods of economic contraction. Furthermore, prior findings of strong summer equity returns are primarily driven by the results found during the periods of economic contraction. It is also found that equity returns are generally higher during periods of economic expansion. 相似文献

When assessing farming strategies, it is important to account for the opportunities provided for tactically adjusting to outcomes of risk. The hypothesis that accounting for tactical adjustment is more important than accounting for risk attitude was supported in this study with regard to identifying the optimal drainage recirculation strategy for an irrigated dairy farm. Failing to account for tactical adjustment would lead to a sub-optimal choice, costing the farmer about A$3 100 in present value terms. In contrast, failing to account for risk aversion would not affect the strategy chosen. The distribution method was found to be well suited to modelling tactical adjustment. 相似文献

The Internet furore over Intel's flawed Pentium chip provides an important case study of the ethical ambiguity of internet communications and the legitimacy of certain forms of "electronic activism". Joseph Badaracco, Jr., is John Shad Professor of Business Ethics at the Harvard Business School and his co-author is a former Research Associate at Harvard and currently on the editorial staff of Inc . magazine. 相似文献
