Nanotechnology is the first major worldwide research initiative of the 21st century. Nanotechnologies are applied to cross industrial problems and are a general purpose technology that acts as both a basis for technology solutions or at the convergence of other enabling technologies, like biotechnologies, computational sciences, physical sciences, communication technologies, cognitive sciences, social psychology and other social sciences. Nanotechnologies are pervasive solution vectors in our economic environment. It is necessary to develop new methods to assess nanotechnologies development to better understand nanotechnology based innovation. As general purpose and enabling technologies, nanotechnologies reveal commercialization processes, from start-ups to large firms in collaboration with public sector research, and which lead to changing patterns of industrial organization which influence public policy initiatives to foster their development. 相似文献

This article describes the application of decision rules from financial portfolio theory to the evaluation of product lines. The focus is on the risk/return implications of an “add” decision to the total portfolio versus the individual product. Multiple criteria approaches that aid product line evaluations are also presented. 相似文献

Interconnection in Network Industries 总被引:4,自引:0,他引:4
Recent deregulation of telecommunications in the U.S. and elsewhere has highlighted the importance of interconnection in network industries. In this paper, we analyse interconnection in a deregulated network where the participants compete in the final retail market. We consider both the case of a mature industry as well as one where a new entrant challenges the incumbent. In the later case, network externalities allow the incumbent to use the terms of interconnection to maintain its dominant position. Moreover, in either case, competition in the retail market can be undermined by collusion over access prices. We discuss the implications for some of the provisions of the new U.S. Telecommunications Act, specifically mandatory interconnection and reciprocity of tariffs, comparing these to the simple bill and keep rule. 相似文献

Organizationally Sensible vs. Legal-Centric Responses to the Eroding Employment At-Will Doctrine 总被引:1,自引:1,他引:0
Most private sector American employers have responded to the uncertainty created by the erosion of the employment at-will doctrine by adopting tactics aimed at avoiding the perceived costs associated with salient legal concerns (e.g., requiring written agreements to preserve the at-will relationship and defeat implied-contract claims). This article discusses the limitations of such a highly legal-centric approach, and provides an alternative decision framework that will promote more strategic, or organizationally sensible, employer responses. In addition to providing specific guidance for employers facing the employment at-will issue, the article's analysis and discussion illustrates a general approach that has relevance wherever organizational decision makers address employment decisions with potential legal implications. 相似文献

Venture Capitalists, Business Angels, and Performance of Entrepreneurial IPOs in the UK and France 总被引:2,自引:0,他引:2

Abstract: Using a unique sample of 444 entrepreneurial IPOs in the UK and France, this paper analyses the investment patterns and the stock-market performance effects of two types of early stage investors: venture capitalists (VCs) and business angels (BAs). Extending existing research, we identify important endogeneity and institutional effects. Our findings indicate that UK IPOs have a higher retained ownership and lower participation ratio by BAs, but a lower retained ownership and participation ratio by VCs than in France. BA and VC investments are substitutes, and they are endogenously determined by a number of firm- and founder-related factors, such as founder ownership and external board 'interlocks', and underwriter reputation. UK VCs are effective third-party certifying agents who reduce underpricing in UK IPOs, whereas in French IPOs they increase it by appearing to engage in grandstanding. This certification effect is more significant in UK IPOs involving both high VC and BA ownership. Finally, underpricing increases with VC participation ratio, where the higher exit of VCs seems to increase the risk premium required by outside investors, in particular in the UK. 相似文献

This research examines the role of imagination difficulty on the evaluation of really new products (RNPs) in comparison with incrementally new products (INPs). We extend past research on accessibility utilizing an anticipatory approach where consumers look forward and generate mental images for future product usage. We found that the role of imagination changes based on the newness of the product. Specifically, for RNPs, imagination difficulty is perceived to be diagnostic in product assessment, and thus, higher imagination difficulty leads to lower product evaluations. However, for INPs, which are shown to be less susceptible to context effects, imagination difficulty has a limited impact on product evaluations. In addition, we show that the effect of imagination difficulty on the evaluation of RNPs is moderated by the level of involvement of the consumer. Research and managerial implications are discussed. 相似文献

In this paper, we examine some popular 'choice modelling' approaches to environmental valuation, which can be considered as alternatives to more familiar valuation techniques based on stated preferences such as the contingent valuation method. A number of choice modelling methods are consistent with consumer theory, and its focus on an attribute‐based theory of value permits a superior representation of many environmental management contexts. However, choice modelling surveys can place a severe cognitive burden upon respondents and induce satisficing rather than maximising behavioural patterns. In this framework, we seek to identify the best available choice modelling alternative and investigate its potential to 'solve' some of the major biases associated with standard contingent valuation. We then discuss its use in the light of policy appraisal needs within the EU. An application to the demand for rock climbing in Scotland is provided as an illustration. 相似文献
