This work identifies the most important determinants of next generation access (NGA) network deployment, using data from the EU27 member states for the years 2005–2011. Our results indicate that the more service-based competition is pronounced the more negative is the impact on NGA deployment, while competitive pressure from broadband cable and mobile affects NGA deployment in an inverted U-shaped manner. We further find that there are severe adjustment costs and stickiness towards the desired long-term level of NGA infrastructure. It appears that the approach of the European Commission to force service-based competition via cost-based access regulation will not elicit the huge new investment needed for a comprehensive NGA roll-out. 相似文献

We study market breakdown in a finance context under extreme adverse selection with and without competitive pricing. Adverse selection is extreme if for any price there are informed agent types with whom uninformed agents prefer not to trade. Market breakdown occurs when no trade is the only equilibrium outcome. We present a necessary and sufficient condition for market breakdown. If the condition holds, then trade is not viable. If the condition fails, then trade can occur under competitive pricing. There are environments in which the condition holds and others in which it fails. 相似文献

Organizational knowledge creation integrates context, knowledge assets, and knowledge creation processes throughout the organization. Using organizational knowledge creation theory as an organizing framework, we conduct a literature review that shows prior work has focused on the role of central, upper‐echelon, leadership in knowledge creation processes, without devoting much attention to context and knowledge assets. To remedy these weaknesses, we develop a new framework for situational leadership in organizational knowledge creation. The framework is based on a continuum that ranges from centralized to distributed leadership at three layers of activity: a core layer of local knowledge creation; a conditional layer that provides the resources and context for knowledge creation; and a structural layer that forms the overall frame and direction for knowledge creation in the organization. We discuss the implications of this framework for theory and practice. 相似文献

This study examines the relevance of financial and non-financial information for the valuation of venture capital (VC) investments. Based on a hand-collected data set on venture-backed start-ups in Germany, we investigate the internal due diligence documents of over 200 investment rounds. We document that balance sheet and income statement items capture as much economic content as verifiable non-financial information (e.g. team experience or the number of patents) while controlling for several deal characteristics (e.g. industry, investment round, or yearly VC fund inflows). In addition, we show that valuations based on accounting and non-accounting information yield a level of valuation accuracy that is comparable to that of publicly traded firms. Further analyses show that the industry-specific total asset multiples outperform the popular revenue multiples but lead to significantly less accurate results than those obtained from the more comprehensive valuation models. Overall, our findings might inform researchers and standard-setters of the usefulness of accounting information for investment companies and provide additional evidence to gauge the overall valuation accuracy in VC settings. 相似文献

Clean technology — Innovation and environmental regulation 总被引:2,自引:0,他引:2
The development and diffusion of clean technologies has an important role to play in preventing pollution. Government must address the issue of how firms can be given the necessary incentive to develop environmentally sound production techniques and products. This paper focus on how subsidies can — under certain restrictive conditions — stimulate innovation. Subsidization is usually assumed to involve unit subsidies for pollution reduction. Unit subsidies have little to do with the subsidy schemes in actual use. Our focus is on subsidy schemes specifically designed to promote the development of clean technologies through the use of grants/financial aid. Based on data from the development projects initiated through The Danish Clean Technology Programme we analyze how environmental innovations take place when the polluters, their suppliers and consultants are actively engaged in the development processes. The main merit of subsidy schemes like the Danish one is its direct focus on the innovation processes and the active incorporation of the network of firms surrounding the polluters. Our findings lead us to conclude that when it comes to subsidization, the role of government should be redefined. Government can act as a matchmaker by providing firms with informative incentives and necessary contacts for finding more efficient technological solutions to specific environmental problems. 相似文献
