To address challenges constraining prior research on evaluation of entrepreneurial projects, we develop the concept of Venture Idea Assessment (VIA) and validate an instrument to capture it. VIA concerns the assessment of Venture Ideas (VI) unbundled from assessment of any agents with whom they may be associated. The assessment can be performed by anybody at any stage of the venture development process, not just by potential founders at its outset. We develop and validate a parsimonious VIA measure across six empirical studies using a broad set of assessors and VIs using interviews, experiments and surveys following real-world start-up processes and decisions. In a research agenda we outline how the VIA platform—the concept and its operationalization—can be employed in novel research across various streams of entrepreneurship research.  相似文献

What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents, therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discriminating patents by technology field, it is demonstrated that patents that receive citations across technology fields survive longer than other patents. Patents that receive citations within the same technology field lapse earlier.  相似文献

We compare two different models for assets and liabilities for an insurance company that can be considered in the standard approach to solvency assessment and in particular, in determining the required target capital. The first model is suggested by a joint working party by members in CEA, Comité Européen des Assurances, and is based on the duration concept and the second one is an application of ideas by Samuelson and Vasicek.  相似文献

Documentation and analysis of prevention goals and interventions employed by community-based injury prevention programmes is vital to advance the knowledge and understanding of synergistic multi-strategy injury prevention programmes. This study examined the goals and interventions of 25 Scandinavian community-based injury prevention programmes in WHO-designated Safe Communities. Collection and analysis of quantitative data from survey questionnaires to the programme coordinators was followed by collection and analysis of qualitative data from structured interviews with programme coordinators from eight of the programmes. The results demonstrated that the programmes under study predominantly relied on "intuitive" and subjective methods for selecting interventions. The programmes largely failed to transform injury surveillance data into information and knowledge that could prioritize community safety strategies and measures, due to insufficient time and personnel resources. The results demonstrated the importance of combining passive approaches with active interventions. Educational efforts were considered essential to the programmes. The programmes preferred to rely on broadly stated goals rather than specific objectives.  相似文献
