University spin‐out (USO) companies play an increasingly important role in generating value from radical, generic technologies, but this translation requires significant resources from other players to reach the market. Seven case studies illuminate how relationships with each type of partner can be leveraged to help the firm create value. We find that most firms in the sample are aware of the importance of corporate partners and actively seek to cultivate these relationships, but may not be taking full advantage of the resources available through nonparent academic institutions and other USOs with similar or complementary technologies.  相似文献

Current guidance in the UK and elsewhere indicate upper and target risk limits for the operation of nuclear plant in terms of individual risk per annum. ‘As low as reasonably practicable’ (ALARP) arguments are used to justify the acceptance or rejection of policies that lead to risk changes between these limits. The suitability of cost‐benefit analysis (CBA) and multiattribute utility theory (MAUT) are assessed for performing ALARP (‘as low as reasonably possible’) assessments, in particular within the nuclear industry. Four problems stand out in current CBA applications to ALARP, concerning the determination of prices of safety gains or detriments, the valuation of group and individual risk, calculations using ‘disproportionality’, and the use of discounting to trade‐off risks through time. This last point has received less attention in the past but is important because of the growing interest in risk‐informed regulation in which policies extend over several timeframes and distribute the risk unevenly over these, or in policies that lead to a nonuniform risk within a single timeframe (such as maintenance policies). The problems associated with giving quantitative support to such decisions are discussed. It is argued that multiattribute utility methods (MAUT) provide an alternative methodology to CBA which enable the four problems described above to be addressed in a more satisfactory way. Through sensitivity analysis MAUT can address the perceptions of all stakeholder groups, facilitating constructive discussion and elucidating the key points of disagreement. It is also argued that by being explicitly subjective it provides an open, auditable and clear analysis in contrast to the illusory objectivity of CBA. CBA seeks to justify a decision by using a common basis for weights (prices), while MAUT recognizes that different parties may want to give different valuations. It then allows the analyst to explore the ways in which different parties might (or might not) come to the same conclusion even when weighting items differently.  相似文献

This paper studies the valuation of a class of default swaps with the embedded option to switch to a different premium and notional principal anytime prior to a credit event. These are early exercisable contracts that give the protection buyer or seller the right to step-up, step-down, or cancel the swap position. The pricing problem is formulated under a structural credit risk model based on Lévy processes. This leads to the analytic and numerical studies of several optimal stopping problems subject to early termination due to default. In a general spectrally negative Lévy model, we rigorously derive the optimal exercise strategy. This allows for instant computation of the credit spread under various specifications. Numerical examples are provided to examine the impacts of default risk and contractual features on the credit spread and exercise strategy.  相似文献

Abstract

Die grossen Influenzaepidemien von 1918 und den folgenden Jahren haben aus natürlichen Gründen das Interesse der Lebensversicherungsstatistiker der ganzen Welt auf sich gelenkt. Statistische Ergebnisse über den Einfluss dieser Epidemien auf die Sterblichkeit von Lebensversicherten findet man so z. B. in folgenden Abhandlungen: Dr. A. WINTER, De sterfte in de laatste jaren. Het Verzekerings-Archief, Jaargang II, No. 2; JAMES D. CRAIG and LOUIS I. DUBLIN, The influenza Epidemic of 1918. Transactions of the Actuarial Society of America, vol. 20, No. 61; R. J. BACKLUND, Dödligheten i spanska sjukan i Kaleva 1918–1920. Nordisk Försäkringstidskrift, Årg. I, n:r 4.  相似文献

The severity of the sanction for a given offense is often determined by the offense history of the offender. We establish that this policy can be welfare-maximizing if individuals are imperfectly informed about the magnitude of the sanction. Imperfect information distorts individuals’ perception of the expected sanction of the first offense. Once detected, individuals learn about the sanction applicable to their act, making this argument less relevant for consecutive offenses.   相似文献

Most innovation studies focus on the activities or characteristics of individuals (agency) or on organizational attributes such as size and formalization (structure). In attempting to reconcile this agency-structure dichotomy we draw on structuration theory to examine the innovation process in detail. Structural properties (signification, domination and legitimation) are constantly reproduced from social interaction (communication, power and sanctions) by means of the modalities (interpretative schemes, facilities and norms) drawn on by knowledgeable, reflexive actors. This framework is utilized to examine the case of a mature manufacturing company in which managers and engineers were attempting to access new technologies. The data were acquired by means of a 6-year, on-going study which began in 1992 and which we suggest is essential for a thorough understanding of the innovation process.  相似文献

Dimensions of the ethical work climate, as conceptualized by Victor and Cullen (1988), are potentially important influences on individual ethical decision-making in the organizational context. The present study examined the direct and indirect effects of individuals' perceptions of work climate on their ethical judgments and behavioral intentions regarding an ethical dilemma. A national sample of marketers was surveyed in a scenario-based research study. The results indicated that, although perceived climate dimensions did not have a direct effect on behavioral intentions, there were significant moderating effects. Climates perceived as emphasizing social responsibility and rules/codes moderated the individual ethical judgment-behavioral intentions relationship such that individuals were less likely to say that they would engage in a questionable selling practice even when they themselves did not believe the practice to be unethical. Respondents were somewhat more likely to form intentions consistent with their judgment that the questionable practice was morally acceptable when the ethical climate was characterized by an emphasis on team/friendship.  相似文献

Environmental social movements in developing countries are often portrayed as democratizing but may contain important social divisions. This paper presents a new methodology to analyze the social composition and underlying political messages of movements. Nearly 5 000 newspaper reports during 1968–2000 in Thailand are analyzed to indicate the participation of middle and lower classes, and their association with “green” (conservationist) and “red-green” (livelihoods-oriented) environmental values. Results show middle-class “green” activism has dominated forests activism, but lower-class “red-green” activism has grown for forests and pollution. Newspapers, however, portray all environmentalism as “democratization,” suggesting that the possible exclusiveness of some environmental norms is unacknowledged.  相似文献

This paper presents a framework that helps researchers to design and validate both formative and reflective measurement models. The framework draws from the existing literature and includes both theoretical and empirical considerations. Two important examples, one from international business and one from marketing, illustrate the use of the framework. Both examples concern constructs that are fundamental to theory-building in these disciplines, and constructs that most scholars measure reflectively. In contrast, applying the framework suggests that a formative measurement model may be more appropriate. These results reinforce the need for all researchers to justify, both theoretically and empirically, their choice of measurement model. Use of an incorrect measurement model undermines the content validity of constructs, misrepresents the structural relationships between them, and ultimately lowers the usefulness of management theories for business researchers and practitioners. The main contribution of this paper is to question the unthinking assumption of reflective measurement seen in much of the business literature.  相似文献
