A line of research is emerging investigating the private sector impacts and dependencies on critical biodiversity and ecosystem services, and related business risks and opportunities. While the ecosystem services narrative is being forwarded globally as a key paradigm for promoting business sustainability, there is scarce knowledge of how these issues are considered at managerial level. This study thus investigates managerial views of corporate sustainability after the ecosystem services concept. We analyse interviews conducted with 20 managers from domestic and international forestry companies operating with a plantation-based business model in China. Content analysis was employed to analyse the data, with a focus on four key areas: (1) interviewee familiarity with the ecosystem services concept; (2) their views of corporate dependencies and impacts on ecosystem services; (3) related business risks and opportunities; and (4) viability of existing instruments and practices that can be employed in detecting and addressing business impacts and dependencies on ecosystem services. Through an inductive approach to the empirical findings, we refined a framework that holds operational value for developing company response strategies to ecosystem services impact/dependence assessment, ensuring that all issues are addressed comprehensively, and that related risks and opportunities are properly acknowledged.  相似文献

This paper examines the impact of Newsweek's ‘The Greenest Big Companies in America’ on stock values for large companies. Newsweek ranks the biggest Companies in America from one to 500. An event window of ten days following the rankings release to the public was examined to analyze the impact of relative rankings on stock values. Dummy variables were constructed denoting firms ranked in the highest and lowest quartiles. Control variables included return to the Dow Jones Industrial Average, the firm's beta coefficient and total revenue. The main finding of the study is that inclusion in the top quartile of the rankings has a positive and statistically significant impact on firms' stock values, while the coefficient for the lowest quartile was not statistically different from zero. The results provide evidence of a positive impact on stock values from favorable environmental recognition but no effect for low ranked firms.

Previous studies suggest that entrepreneurs play a key role in the success of their ventures. But relatively little is currently known about how they produce such effects. The present research provides data suggesting that two modes of entrepeneurs’ self‐regulation—locomotion and assessment—enhance a firm's success through their effects on the components of alertness. This mediational model was tested and supported with data from 120 entrepreneurs. Locomotion was positively related to the scanning and search component, while assessment was positively related to the association and evaluation components. These findings are discussed in terms of the role of founders’ self‐regulation in the performance of their companies.  相似文献

The Effects of Firm Size and Industry on Corporate Giving   总被引:1,自引:0,他引:1  
Recent downward trends in corporate giving have renewed interest in the factors that shape corporate philanthropy. This paper examines the relationships between charitable contributions, firm size and industry. Improvements over previous studies include an IRS data base that covers a much broader range of firm sizes and industries as compared to previous studies and estimation using an instrumental variable technique that explicitly addresses potential simultaneity between charitable contributions and profitability. Important findings provide evidence of a cubic relationship between charitable giving and firm size and evidence of strong industry effects. The plus-minus-plus regression coefficient sign pattern for the cubic firm size model suggests that small and large firms give more relative to total receipts with lower giving ratios among medium size firms. One interpretation for this finding is that small firms are close to the communities they serve while high visibility creates a need for large firm philanthropy. Strong industry effects provide evidence of inter-industry differences in giving culture and/or different public relations requirements across industries. Christie H.

In an attempt to better understand the main motives behind organic food consumption, this study explores the consumer discourses of organic food. In all, 35 in-depth interviews were conducted, from which three major discourses were identified. These discourses were named primitivist, retro, and racialist. The data suggest that these Romantic discourses play on images of a supposedly glorious and innocent past. Consequently, consumers using these three discourses were more likely to prefer organic food, as they had a tendency to construct this type of food as more natural, authentic, and real. In this sense, Romantic discourses seem to offer more resonant themes for consumers than contemporary modern science can ever provide.  相似文献

Short-Term Load Forecasting (STLF) is a fundamental instrument in the efficient operational management and planning of electric utilities. Emerging smart grid technologies pose new challenges and opportunities. Although load forecasting at the aggregate level has been extensively studied, electrical load forecasting at fine-grained geographical scales of households is more challenging. Among existing approaches, semi-parametric generalized additive models (GAM) have been increasingly popular due to their accuracy, flexibility, and interpretability. Their applicability is justified when forecasting is addressed at higher levels of aggregation, since the aggregated load pattern contains relatively smooth additive components. High resolution data are highly volatile, forecasting the average load using GAM models with smooth components does not provide meaningful information about the future demand. Instead, we need to incorporate irregular and volatile effects to enhance the forecast accuracy. We focus on the analysis of such hybrid additive models applied on smart meters data and show that it leads to improvement of the forecasting performances of classical additive models at low aggregation levels.  相似文献

Background: Evidence of the cost-efficacy of ixekizumab for the treatment of moderate-to-severe plaque psoriasis (PsO) in the US is limited.

Objective: To estimate the number needed to treat (NNT) and monthly cost of achieving one additional Psoriasis Area and Severity Index (PASI) 75, 90, and 100 responder for ixekizumab and other Food and Drug Administration (FDA)-approved biologics in PsO.

Methods: A network meta-analysis estimated the probability of achieving PASI 75, 90, or 100 response during induction for each biologic. NNTs were calculated using response difference of each respective biologic vs placebo at the end of induction. Monthly costs per additional PASI responder were based on FDA-approved doses, wholesale acquisition costs, and induction NNTs.

Results: Induction NNTs for ixekizumab 80?mg once every 2 weeks (Q2W) relative to placebo were consistently lower across all levels of clearance compared with the other biologics. Monthly cost per additional responder was lowest for ustekinumab 45?mg at PASI 75 and for secukinumab 300?mg and ixekizumab 80?mg Q2W at PASI 90. Ixekizumab 80?mg Q2W had the lowest cost for PASI 100.

Conclusion: In this analysis, ixekizumab is the most cost-efficient biologic in the US when targeting complete resolution, as measured by PASI 100 in PsO.  相似文献

This paper compares the inferences gained when alternatively specifying Census-based price-cost margin and IRS-based accounting rate of return as the dependent variable in conventional structure-performance models. We find important differences between the structure-performance inferences of the alternative specifications of the profit measure. Further, the alternative profit measures are not highly correlated.The authors acknowledge the constructive comments of an anonymous referee.  相似文献

This article investigates the effects of firm size, profitability, industry affiliation, and the business cycle on retailer philanthropy. The importance of industry and firm effects on giving was analyzed with regression models using industry-fixed effects as well as firm strategy variables. The analysis included instrumental variables methodology to account for simultaneity in the charitable giving–profits relationship. Data were gathered from the IRS Corporate Statistics of Income Sourcebook, data that provide firm size class measures covering the entire firm size distribution ranging from small retailers up to large multi-national retail firms. Retailer philanthropy was measured as the ratio of charitable contributions to total receipts. Important findings include a cubic relationship between retailer philanthropy and firm size; industry effects stronger than those observed for retail profit; and the absence of business cycle effects. The empirical research relating retail charitable giving to firm attributes including firm size and advertising, industry and business cycle factors are unique in the business ethics literature. Prior studies regarding the importance of industry on charitable giving utilized data across broad sectors of the economy. Firms from different sectors could be expected to differ in philanthropic approach due to differences in public contact as well as differences in public relations exposure. The strong industry effects reported for this sample of exclusively retail firms, with similar public contact, provide strong evidence for the importance of industry in determining firms’ charitable strategies.  相似文献
