above the certainty level while for additive uncertainty the price should be lower than the certainty level. This note gives an intuitive explanation for the result after first presenting a parsimonious review
of the two models. We also discuss which, if either, of the two models is more realistic.

Improving access is a priority in the offshore wind sector, driven by the opportunity to increase revenues, reduce costs, and improve safety at operational wind farms. This paper describes a novel method for producing probabilistic forecasts of safety-critical access conditions during crew transfers. Methods of generating density forecasts of significant wave height and peak wave period are developed and evaluated. It is found that boosted semi-parametric models outperform those estimated via maximum likelihood, as well as a non-parametric approach. Scenario forecasts of sea-state variables are generated and used as inputs to a data-driven vessel motion model, based on telemetry recorded during 700 crew transfers. This enables the production of probabilistic access forecasts of vessel motion during crew transfer up to 5 days ahead. The above methodology is implemented on a case study at a wind farm off the east coast of the UK. 相似文献

This paper demonstrates how meta‐analysis can be combined with structural equation modeling (MASEM) to address new questions in strategic management research. We review this integration, describe its implementation, and compare findings from bivariate meta‐analyses, a direct‐effect structural equations model, and two mediating frameworks using data on the strategic leadership and performance relationship. Results drawn from 208 articles that collectively included data on 495,638 observations demonstrate the new insights available from MASEM while also suggesting a revision to conventional thinking on strategic leadership. Whereas some theories posit that boards of directors influence firm performance through monitoring and disciplining the top management team, MASEM provides more support for the view that boards mediate the top management teams' decisions. Implications for applying MASEM in strategic management are offered. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

This paper considers the use of value capture (VC) as a means of financing public‐private partnerships (PPPs) in the United Kingdom (UK). Although some VC techniques are used in the UK, they are employed more widely in the United States of America. After considering the traditional approach to financing UK PPPs, this paper describes the main VC finance instruments. The findings of a series of case studies are then presented and conclusions drawn. While VC financing may prove unpopular with those bearing the cost of infrastructure improvements, it is recommended that such instruments are considered by UK policy makers. 相似文献

Although much has been attributed to a CEO's personality, one particularly intriguing, and as yet unexplored, investigation is its impact on the firm's entrepreneurial orientation. Additionally, despite calls from the upper‐echelon literature, CEO personality research has been hobbled by the absence of a unifying construct that captures core dimensions of personality, and by the difficulty in obtaining such intimate assessments from executives. Building on recent advances in personality research, in particular the identification and validation of the core self‐evaluation construct that captures the core facets of an executive's sense of self‐potency, we develop and test a model of the impact of CEO core self‐evaluation on entrepreneurial orientation. Then, consistent with upper echelons and personality theory, we specify the contingent role of environmental dynamism. Using multisource data from a sample of CEOs and their top management teams from 129 firms, including a time‐lagged assessment of the firm's entrepreneurial orientation, we find evidence to suggest that CEOs whose personalities reflect higher core self‐evaluations have a stronger positive influence on their firms' entrepreneurial orientation. In addition, we find that this influence is particularly strong in firms facing dynamic environments, but negligible in stable environments. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

This paper models capacity utilisation as a cyclical variable that reflects both the value of precautionary capacity and the desire to hold strategic excess capacity. Business unit data from the Profit Impact on Marketing Strategy (PIMS) database of large, predominantly US, companies are used. Separate estimation is carried out for a number of SIC industry groups. Panel data estimation in first difference instrumental variable form is employed. Unlike many previous studies the utilisation variable is well determined. The results show significance for precautionary and strategic effects in particular industries. The paper discusses the reasons for the industry specificity of the results. Policy implications are discussed. 相似文献
