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

This paper reports on aspects of land tenure in western Sudan, especially the nature of tenure insecurity and the functioning of the land rental market. The active land rental market accounted for about one-third of cultivated land. Patterns of land rental transactions, and tests of the importance of insecurity in renting land, where the owner may not be able to reclaim land rented out, do not support the presumption that rental markets perform poorly. The role of the sheikh as administrator of village land, and the claims of large landowners to vast tracts, are, however, important political problems that must be resolved before attempts at ‘rationalizing’ land tenure.  相似文献

Abstract: The dwindling nature of overseas development assistance in the early part of the 1990s called for the establishment of capital markets in some African countries, including Ghana, with the view to increasing foreign direct investments and achieving sustainable inflows, growth and development. One important factor which affects the determination of prices and the growth of capital markets is macroeconomic risk which is quite high in developing countries. Following works done on advanced stock markets, this study seeks to investigate the impact of six macroeconomic risk factors on asset pricing in the various industrial classification — financial, manufacturing, food and beverages, distribution and mining under the Ghana Stock Exchange (GSE) for the period January 1997 to December 2002. Using the arbitrage pricing methodology developed by Ross (1976) and Chen et al. (1986) , the study revealed that investors in Ghana considered three main macroeconomic risk factors — short‐term interest rate risk, inflation risk and the term structure of the country's interest rate in the determination of the various industrial asset prices during the period under consideration. Analysis of the risks and returns profile of the industries also shows that financial assets made the best gains on the market. Both general and specific policy recommendations aimed at improving the performance of the GSE are explored.  相似文献

This study explores the impact of environmental turbulence on relationships between personal and organizational characteristics, personal values, ethical perceptions, and behavioral intentions. A causal model is tested using data obtained from a national sample of marketing research professionals in South Africa. The findings suggest turbulent conditions lead professionals to report stronger values and ethical norms, but less ethical behavioral intentions. Implications are drawn for organizations confronting growing turbulence in their external environments. A number of suggestions are made for ongoing research. Michael H.

This study reports the results of a survey designed to assess the impact of education on the perceptions of ethical beliefs of students. The study examines the beliefs of students from selected colleges in an eastern university. The results indicate that beliefs which students perceive are required to succeed in the university differ among colleges. Business and economics students consistently perceive a greater need for unethical beliefs than students from other colleges. Michael S.

Three years after launching the team-based Quality For All program, Top Chemical Company CEO Sam Verde was searching for a team-based compensation system that would reflect his company's new philosophy. With a committee gathered to discuss the issue, Verde confronts the fact that changing pay plans is an issue few people can agree on. "Very simply," explains vice president for compensation Gilbert Porterfield, "the plan is designed to give employees working on teams real incentives for constant improvement and overall excellence. The variable aspect of the system pays employees for the performance of their group." This doesn't sit well with the others. "It's going to punish teams like mine for the failings of others instead of rewarding us for the work we do and have already done," says packaging team representative Ruth Gibson. Another committee member feels that team-based anything is a "motivational happy land that doesn't square with how people really work." While Verde likes the proposed pay plan, he has doubts over whether his employees will accept the risk. Upper management has no problem basing 60% of its pay on TopChem's performance. But getting line employees to risk part of their salaries--even as little as 4%--on the ups and downs of the chemical industry may be more trouble than it's worth. Four experts on compensation reveal where Top Chemical went wrong in its plan and how Sam Verde might bring about change successfully.  相似文献
