The primary purpose of this study was to examine factors that influence the effectiveness of benefit appeal types (i.e., help-other vs. help-self) in Corporate Social Responsibility advertising. To that end, we designed and administered a between-subjects experiment where participants viewed one of the two CSR advertisements crafted with help-self and help-other benefit appeals. Results provided evidence supporting the moderating effects of status-consumption motives and age on purchasing intentions. Additional analysis suggested consumers younger than 48 years old were more likely to be persuaded by a help-other ad appeal when they didn't have strong desires for status consumption. Results were discussed in light of the self-concept theory and value-expressive framework in CSR advertising.  相似文献

公司治理结构的理论基础是委托—代理和企业的不完全契约。从实践看 ,目前在发达国家主要存在两类形式的公司治理机制 ,即英美模式和日德模式。两者在股权结构、组织结构、市场环境、法律制度、激励方式上均存在差异。英美模式侧重于依赖市场机制 ,而日德模式更倾向于公司内部的治理。  相似文献

基于VaR-GARCH模型对证券投资基金风险的实证研究   总被引:5,自引:0,他引:5

根据证券投资基金收益率序列的尖峰厚尾特征,建立估计基金风险的VaR—GARCH模型。在正态分布、t分布及GED分布三种不同的分布假设下,对基金的VaR值进行估计,并应用Kupiec失败频率检验方法对VaR模型的准确性进行了返回检验。研究结果表明,相比之下,基于GED分布的GARCH模型计算的VaR值最能真实地反映基金风险。  相似文献

基于城市户外广告媒体监管机制的文献梳理和现实回顾,分析了城市户外广告的监管主体和监管机制,阐述了城市户外广告媒体监管的不确定性风险,即政府俘获造成寻租风险,资源开发造成产权风险,特许经营造成市场风险,并结合监管过程中的治理冲突,尝试构建城市户外广告监管的协作性公共管理系统。该系统以政府、行业与公众三方互动为输入,通过协作性管理的转换机制输出良好的广告秩序和经济效益,实现治理模式从单一垄断向多元互动模式的转变。  相似文献

As the focus of environmental policy and management shifts from cleaner production at the process level towards greener products as a whole, stakeholders ask for transparency throughout the entire value chain. This article assesses the comprehensiveness and the value of currently reported quantitative environmental disclosures of 97 listed companies from the automotive, banking, pharmaceutical and electronic hardware sectors. Findings indicate that quantitative environmental disclosures have many limitations, including incompleteness and inconsistency regarding corporate activities and sites, and limited internal data coherence. For many sectors, corporate disclosures only cover a very small share of the total environmental burden of products. A stepwise procedure is proposed to verify and improve the quality and completeness of reporting using life cycle approaches. We present simple data quality tests, and we introduce the concept of the environmental influence matrix, which provides a solid basis for the identification and prioritization of key performance indicators and areas of action.

This paper explores the theoretical underpinnings of collaboration and ecosystem management in order to identify the relationships and processes involved in implementing ecosystem management programs through cross‐sector collaboration. Ecosystem management requires a highly adaptive and resilient social–ecological governance approach, which addresses spatiality and temporality issues. In order to explore possible implementation issues with ecosystem management, propositions are developed dealing with adaptive governance, institutional isomorphism and collective action. The paper concludes with a discussion of the theoretic underpinnings involved in implementing ecosystem management through cross‐sector collaborations.

Cities are key drivers of global climate change, with the majority of greenhouse gas (GHG) emissions being tied to urban life. Local actions to mitigate and adapt to climate change are essential for stabilization of the global climate and can also help to address other urban ecological problems such as pollution, decreasing biodiversity, etc. Companies are important urban actors in the development of low‐carbon cities because they provide a multitude of goods and services to city populations and directly influence urban carbon dioxide (CO2) emissions. This is a new area of research. While studies on corporate sustainability are numerous, there is little, if any, existing research that examines the role of companies in climate change adaptation and mitigation within specific urban areas. Urban ecologists also have not examined how corporate activity affects urban systems. Taking a multi‐disciplinary systems approach, we present a conceptual model of the role of companies in managing urban interactions with the climate system. We also present empirical findings illustrating how one company ‘partners’ with the city of Rotterdam to test electric vehicles as a pilot project for urban climate adaptation and mitigation.
