This paper extends a broad functional category approach for the study of technological capability progress recently developed and applied to information technology to a second key case—that of energy based technologies. The approach is applied to the same three functional operations—storage, transportation and transformation—that were used for information technology by first building a 100 plus year database for each of the three energy-based functional categories. In agreement with the results for information technology in the first paper, the energy technology results indicate that the functional approach offers a stable methodology for assessing longer time technological progress trends. Moreover, similar to what was found with information technology in the first study, the functional capability for energy technology shows continual—if not continuous—improvement that is best quantitatively described as exponential with respect to time. The absence of capability discontinuities—even with large technology displacement—and the lack of clear saturation effects are found with energy as it was with information. However, some key differences between energy and information technology are seen and these include:
?
Lower rates of progress for energy technology over the entire period: 19-37% annually for Information Technology and 3-13% for Energy Technology.
?
Substantial variability of progress rates is found within given functional categories for energy compared to relatively small variation within any one category for information technology. The strongest variation is found among capability progress among different energy types.
?
More challenging data recovery and metric definition for energy as compared to information technology.
These findings are interpreted in terms of fundamental differences between energy and information including the losses and efficiency constraints on energy. We apply Whitney's insight that these fundamental differences lead to naturally modular information technology artifacts. The higher progress rates of information-based as opposed to energy-based technologies follows since decomposable systems can progress more rapidly due to the greater ease of independent as opposed to simultaneous development. In addition, the broad implications of our findings to studies of the relationships between technical and social change are briefly discussed.  相似文献

This paper studies a differentiated-good oligopoly where the socially optimal number of firms (varieties) may be smaller or greater than under the free-entry equilibrium. We show that, under certain conditions, social welfare may be higher when entry is restricted into the industry.  相似文献

Retailers are now implementing the types of formal marketing planning programs that have long characterized consumer goods firms. The functional marketing plans that are developed tend to be a year or less in duration. The primary responsibility for developing the plans resides with the general merchandise manager. The planning efforts of the retailing executive, in spite of their short term nature, do reflect an awareness of the importance of understanding the strengths and weaknesses of competitors and of the need to spell out issues involving profit planning, sales promotion planning, merchandise addition/deletion decisions, and issues involving inventory/physical distribution. A variety of marketing plans are developed. Separate plans are developed by merchandise lines in many organizations. The authors wish to express their appreciation to The Conference Board for permission to use the questionnaire, with modifications, underlying research for The Marketing Plan, Report No. 801, The Conference Board, 1981, as the basis for formulating the questionnaire used in this research  相似文献

During the recent and ongoing economic turmoil, countless businesses have been facing financial distress and many have filed for bankruptcy. This issue is especially critical for the restaurant industry due to restaurants’ sensitivity to economic fluctuations. Therefore, the purpose of this study is to examine the financial distress issue in the U.S. restaurant industry. In particular, the study examines a moderating effect of capital intensity on the relationship between a firm's leverage and degree of financial distress. The dataset includes publicly traded U.S. restaurant firms during the period 1990–2008. The study measures the degree of financial distress by modified Z-scores, and findings suggest a positive moderating effect of capital intensity on the relationship between leverage and financial distress.  相似文献

Reviewing the literature about interactive leadership and its effects on human resource management in business organizations, this paper proposes that interactive leadership has two major components: interaction skills and team building. Both components have positive effects on employees' trust in their leaders, on employees' motivation and employees' commitment to their companies. Based on these hypotheses, the paper develops an empirical test of the effectiveness of interactive leadership in Singapore's banking industry. Seventy-seven middle-level managers participated in this study by responding to a questionnaire about their leaders, their motivation, their commitment and their trust in these leaders. The results support the hypotheses and suggest some important implications for human resource management in business organizations, especially for human resource management in Oriental societies.  相似文献

Summary. This paper investigates the optimality of intertemporal price discrimination for a durable-good monopoly in a model where infinitely-lived households face an intertemporal budget constraint, and consume both durable goods and non-durable goods. We prove that the optimal price of the durable good is not constant, and may decrease or increase over time. Some households may choose to purchase the durable good at a later date, and pay lower or higher prices, since the gain in discounted utility of consuming more of the non-durable good more than compensates for the loss in utility from delaying the consumption of the durable good.Received: 12 March 2004, Revised: 7 January 2005, JEL Classification Numbers: D40, D42, D91.I would like to thank C.D.

Although annuities are a theoretically appealing way to manage longevity risk, in the real world relatively few consumers purchase them at retirement. To counteract the possibility of retirees outliving their assets, Singapore's Central Provident Fund, a national defined contribution pension scheme, has recently mandated annuitization of workers’ retirement assets. More significantly, the government has entered the insurance market as a public‐sector provider for such annuities. This article evaluates the money's worth of life annuities and discusses the impact of the government mandate and its role as an annuity provider on the insurance market.  相似文献

Based on a survey of 237 managers in Singapore, three measures of organizational ethics (namely, top management support for ethical behavior, the organization's ethical climate, and the association between ethical behavior and career success) are found to be associated with job satisfaction. The link between organizational ethics and job satisfaction is argued from Viswesvaran et al.'s (1998) organizational justice and cognitive dissonance theories. The findings imply that organizational leaders can favorably influence organizational outcomes by engaging in, supporting and rewarding ethical behavior.  相似文献
