Climate change's impact on investor behavior is a scantly investigated area in finance. This paper examines the performance of socially responsible exchange trade funds (ETFs) concerning conventional ETFs, in response to climate change events. We proxy climate change signals with a list of natural disaster events that NASA scientists relate to climate change. We contribute to existing literature, by using a very extensive information set of ETF strategies, not influenced by rating agencies' subjective evaluation policies, and covering almost 90% of the universe of worldwide sustainability thematic-oriented ETFs. This sample allows us to identify the socially responsible investment behavior in response to unpredictable climate change shocks. Our identification strategy accounts for endogeneity concerns and relies on two-stage least square (2SLS) approach finding that responsible investors react to climate change events by purchasing socially responsible investments. The relationship between climate change signals and return of investment in themes linked to the development of sustainability is positive. Interestingly enough, the sign of this relationship is different, when we disentangle the empirical results according to the asset type, confirming that investors shift their investments from equity funds to bond funds when market sentiment worsens. Our results indicate that policymakers should increase the support of firms adopting environmentally conscious business practices, while managers should boost a sustainable business strategy.  相似文献

After two decades of research on Emerging Market Multinational Enterprises (EMNE), the debate still concerns the antecedents and strategies of their foreign expansion. However, much less has been said on the effects of international participation on their productivity. Building on insights from the Resource-Based View of the firm and agency theory, we develop hypotheses on the presence of complementarities among export, import and R&D and their impact on productivity. Our empirical analyses on a panel of 23,000 time-year observations of Ukrainian MNEs over the period 2000–2006, confirm that: (i) EMNEs benefit from complementarities stemming from the assimilation and integration of knowledge from international external sources (import and export) with internal knowledge (own R&D investment); (ii) the effect is more pronounced for private-owned enterprises (POEs) rather than state-owned enterprises (SOEs), and (iii) especially when they trade with partners in/from advanced markets.  相似文献

上市公司可持续增长率偏差的实证分析   总被引:1,自引:0,他引:1  
按照可持续增长率进行发展,要求企业全面权衡各方面的契约关系,以稳定的契约结构获取企业的长期增长。但是在现实中由于各种原因,企业不可能完全按照可持续增长率进行增长,出现了可持续增长率偏差。本文通过对我国A股市场的上市公司在1997-2005年的可持续增长情况进行分析,研究了我国上市公司可持续增长率偏差的主要影响因素及其对未来经营业绩的影响。研究结果表明:影响可持续增长率偏差的主要因素包括资产运作效率变动、资本结构的调整、外部权益融资和销售净利率的变化,鼓励政策对企业的可持续增长率偏差并没有显著作用。另外本文还验证了较高的可持续增长率偏差对后期(5年)的业绩提高具有消极作用。  相似文献

成本计量模式与企业成本控制机制研究   总被引:3,自引:0,他引:3  
成本计量模式存在着制造环节、价值链与商业模式三个视角的划分,它们反映了不同成本效益对称情形,三者间具有层次演进性。从成本与利润的关系看,企业内部就是成本计量,利润则是市场角度的成本补偿计量,企业机制就可以视为在有意义的领域做出独特或某种与众不同的贡献而进行的成本流程安排。企业健康成本结构应该是一个开放的以接纳先进价值观的信息综合体。企业要获得可持续竞争力就必须树立科学的成本控制观念。  相似文献

Airport capacity continues to be one of the air transport issues that creates the most concern. The major environmental constraint for airports is the noise generated by aircraft. Annoyed communities living around airports have become a limiting factor for airport capacity and operability. This paper brings together the existing literature in the fields of airport environmental capacity, non-acoustic factors of noise annoyance, NIMBYism and environmental conflicts. We also analyze the socio-environmental conflict between Barcelona airport and the community of Gavà Mar. This case shows that the lack of trust between parties, the impossibility of predicting noise exposure, the absence of opportunities for civil society to speak and the difficulty of accessing relevant information foster annoyance and mobilization in the communities that live around the airport. In addition, it is shown that, in such a situation, communities’ reactions can evolve to a post-NIMBY stage in which proactive attitudes replace reactive ones.  相似文献

Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in recent years, digital platforms have turned into the most important actors in the global sharing economy, turning global corporations, such as AirBnB, Booking, or TripAdvisor into intermediaries controlling and profiting from most transactions. Focused on accommodation, this paper conceptualizes the sharing economy in comparison to the wider collaborative economy, and discusses its social, economic, environmental, and political impacts in comparison to the sustainable development goals. It concludes that the sharing economy has great potential to make very significant contributions to sustainability, though the model is increasingly being replaced by the collaborative economy, which performs as an extension and acceleration of neoliberal economic practices.  相似文献
