The paper presents the cost of sequential and parallel research strategies in multiproject R&D characterized by spillovers between the projects. Larger spillovers associated with a sequential strategy prove to be insufficient to guarantee a cost advantage for this option. This provides a rationale for a parallel research strategy with some duplication of effort, as observed in some real-world R&D environments. 相似文献

In a newly liberalized credit market, foreign banks with cost advantages are likely to be less informed than domestic banks that hold information on credit risks. These relative advantages may generate incentives for a foreign bank to negotiate acquisition of a domestic bank in order to capture information endowments. However, if it is difficult to assess the value of information held by banks, the foreign bank will face important choices about the optimal mode of entry and what acquisition price to pay. These choices have implications for the survival of domestic banks and how capital is allocated after liberalization. 相似文献

Technological diversification at the firm level (i.e., the expansion of a firm's technology base into a wide range of technology fields) is found to be a prevailing phenomenon in all three major industrialized regions,—the United States, Europe, and Japan—prompting the term multitechnology corporation. Whereas previous studies have provided insights into the composition of technology portfolios of multitechnology firms, little is known about the relationship between technological diversification and firms' technological performance. Against a backdrop of the technology and innovation management literature, the present article investigates the relationship between technological diversification and technological performance, taking into account the moderating role of technological coherence in firms' technology portfolios. Hereby, technological coherence is defined as the degree to which technologies in a technology portfolio are technologically related. To measure the technological coherence of portfolios, a measure of technological relatedness of technology fields is constructed based on patent citation patterns found in 450,000 European Patent Office (EPO) patent grants. Two hypotheses are presented here: (1) Technological diversification has an inverted U‐shaped relationship with technological performance; and (2) technological coherence moderates the relationship between technological diversification and technological performance positively. These hypotheses are tested empirically using a panel data set (1995–2003) on patent portfolios pertaining to 184 U.S., European, and Japanese firms. The firms selected are the largest research and development (R&D) actors in five industries: pharmaceuticals and biotechnology; chemicals; engineering and general machinery; information technology (IT) hardware (i.e., computers and communication equipment); and electronics and electrical machinery. Empirical results, obtained by fixed‐effects negative binomial regressions, support both hypotheses in the present article. Technological diversification has an inverted U‐shaped relationship with technological performance. Technological diversification offers opportunities for cross‐fertilization and technology fusion, but high levels of diversification may yield few marginal benefits as firms risk lacking sufficient levels of scale to benefit from wide‐ranging technological diversification, and firms may encounter high levels of coordination and integration costs. Further, the results show that the net benefits of technological diversification are higher in technologically coherent technology portfolios. If firms build up a technologically coherent diversified portfolio, the presence of sufficient levels of scale is ensured and coordination costs are limited. At the same time, technologically coherent diversification puts firms in a better position to benefit form cross‐fertilization between technologies. The present article clearly identifies the important role of technological coherence in technology diversification strategies of firms. 相似文献

Electronic markets are virtual meeting places where buyers and sellers interact to trade products or services. The main motivation for both buyers and sellers to participate in an electronic market is the desire to maximize their private utility (Bakos 1998). Electronic markets therefore usually provide some form of communication, decision or negotiation aid for buyers and sellers to support their utility maximizing goals. This paper presents a comparative analysis of two electronic job market case studies conducted at a university in Europe (Brussels, Belgium) and in the United States (Newark, New Jersey). At the occasion of the universities’ career fairs, students (n = 392) and local companies (n = 57) were invited to participate in an electronic job market to identify the best job offers (n = 137) and students, respectively. Participants were able to create personalized software agents to aid their search and decision making activities in the market. Every software agent was embedded with a multi-criteria decision support tool to produce a rank ordered list of students or job offers. Preference data gathered from market participants’ use of the multi-criteria decision model allow us to construct relational preference structures using a technique based on the mathematical theory of fuzzy relations (Bandler and Kohout 1980). These preference structures express relationships among the criteria that students and companies have used to identify job offers and companies, respectively. The purpose of the paper is to present the communicative and cultural implications of these relational preference structures. The theories of Hofstede (1983), Hall (1977) and Trompenaars (1993) on cultural dimensions allow us to discuss cultural differences on the choice of prototypical criteria. The paper concludes with implications for the use of electronic markets in the staffing industry and the role of software agents in such job markets. 相似文献

The European Corporate Sustainability Framework (ECSF) is, among other concepts, based on a phase-wise development approach as described by Clare Graves' Levels of Existence Theory. As much as corporate sustainability has a sequence of adequate interpretations, aligned with each development level, also the notion of business excellence can be defined at multiple levels, as this paper demonstrates. Furthermore, the authors analyze the current EFQM Excellence Model for particular biases towards various development levels and suggest a new and innovative two-step approach to assessing organizational performance with respect to organizational excellence (OE) and corporate sustainability. According to the organization's ambition, the assessment is either limited to a shareholder approach, mainly focusing at optimal usage of resources, or it also includes an additional assessment format based on the stakeholder approach, with specific reference to the organization's performance on the financial, social and ecological bottom line. This paper demonstrates the need and feasibility of an EFQM-Based assessment tool with a combined focus on corporate sustainability and OE. 相似文献

The present study describes age differences in the occurrence of career activities among profit sector and non‐profit sector employees in the Netherlands. Three different types of variables have been studied, i.e. individual, job‐related and organizational variables. Hypotheses have been tested with original survey data from 423 profit sector employees and 136 non‐profit sector employees. The employees are all working in higher‐level jobs in large organizations. Overall, we may conclude from this study that the differences between profit sector and non‐profit sector workers are not consistent at all. For some factors the situation is more advantageous for profit sector employees, whereas for other factors the outcomes point in the opposite direction. Regarding age effects, we have found that, in general, for profit sector employees the differences between starters (20–34 years) and middle‐aged workers (35–49 years) are not univocal, whereas the differences between middle‐aged workers and seniors (over‐fifties) imply that the amount of individual initiatives and organizational activities is less for the latter group of employees. When the three age groups are compared for the non‐profit sector employees, most factors do not vary significantly. For the factors where the F‐test is found to be significant, by and large, the situation regarding the possibilities for a further career development is worst for the seniors. 相似文献

Organizational Identification during a Merger: The Role of Self‐Enhancement and Uncertainty Reduction Motives during a Major Organizational Change 下载免费PDF全文

Past research focuses predominantly on self‐enhancement as a motive underlying organizational identification even though there have been several calls for examining multiple motives of identification. Our research explores the interplay of the self‐enhancement and the uncertainty reduction motives in shaping identification during a major organizational change: a merger of a business unit with its parent corporation. Based on analysis of survey responses collected from 751 employees of the merging business unit, we find that the self‐enhancement motive, measured via attractiveness of perceived organizational identity and perceived external prestige, continues to influence identification during this merger. However, its effects are diminished when considering the effect of the uncertainty reduction motive. In particular, in addition to affecting identification directly, this latter motive, measured via agreement with projected identity of the business unit and identification with a distal target (i.e., the parent corporation), decreases the effect of perceived external prestige on business unit identification. Our research answers longstanding calls for understanding organizational identification motives beyond self‐enhancement, and shows how multiple identification motives work during a major organizational change: a time when identification is strongly needed, yet hard to garner. 相似文献
