We suggest that the distortion of the positive risk–return relation in the ICAPM is a consequence of trading by informed investors to exploit mispricing. We hypothesize and demonstrate that a non-positive (strongly positive) risk–return relation following positive (negative) market returns is attributed to short-selling (purchasing) of overpriced (underpriced) stocks along with optimistic (pessimistic) expectations conditional on good (bad) market news. We verify this asymmetry in the risk–return relation through the indirect risk–return relation conditional on good (bad) market news. We also find that the attenuation (reinforcement) of the positive risk–return relation is more profound in high- (low-) sentiment periods.  相似文献

This paper examines the impact of bank-specific factors and variations in the context of stringency of government policy responses on bank stock returns because of the COVID-19 pandemic. A sample of 1,927 publicly listed banks from 110 countries is used for the period of the first major wave of COVID-19, that is, January to May 2020. Our findings indicate that stock returns of banks with higher capitalization and deposits, more diversification, lower non-performing loans, and larger size are more resilient to the pandemic. While banks’ environment and governance scores do not have a significant impact, higher social and corporate social responsibility strategy scores intensify the negative stock price reaction to COVID-19. We further observe that the pandemic-induced reduction in bank stock prices is mitigated as the strictness of government policy responses increases, mainly through economic responses such as income support, debt and contract relief, and fiscal measures from governments.  相似文献

We commemorate the 50th anniversary of Ball and Brown [1968] by chronicling its impact on capital market research in accounting. We trace the evolution of various research paths that post–Ball and Brown [1968] researchers took as they sought to build on the foundation laid by Ball and Brown [1968] to create a body of research on the usefulness, timeliness, and other properties of accounting numbers. We discuss how those paths often link back to the groundwork laid and questions originally posed in Ball and Brown [1968].  相似文献

Nonprofit arts and cultural organizations use marketing to sustain viability. This study uses data from the Cultural Data Project to examine the effects of marketing on revenue in arts and cultural organizations. The current analysis demonstrates that total marketing expense is positively related to total revenue. Marketing expense used for fund‐raising positively influences donation income, as intended, whereas commercial income is not affected. Alternatively, marketing expense for programs positively influences both commercial income, as intended, and donation income. The novel finding from this study is that marketing expense mainly targeting non‐donor ticket buyers not only increases commercial income but also augments donation income in arts and cultural organizations.  相似文献

针对传统的频谱分析和自相关函数反演周期时常出现虚假周期的问题,提出了多重交叉残差法处理空间旋转目标雷达散射截面(Radar Cross Section,RCS)的时间序列。以空间跟踪和监视系统(Space Tracking and Surveillance System,STSS)卫星为例,仿真了空间目标失稳旋转状态,对比了频谱分析、自相关函数和多重交叉残差3种方法的处理结果,发现当目标存在进动运动时多重交叉残差法抗干扰能力更强。在此基础上,进一步研究了不同章动角时多重交叉残差法对旋转周期的反演效果,结果表明章动角大小会影响旋转周期的反演准确度,且章动角达到一定数值后,卫星进动幅度过大导致RCS序列周期性模糊,无法用多重交叉残差法反演出旋转周期。  相似文献

Payments for ecosystem services (PES) are environmental management tools that enable corporations to simultaneously enhance their environmental performance and fund sustainable development in rural areas. PES is primarily promoted as part of a sustainable production strategy for conserving natural resources, offsetting carbon emissions, and green supply chain management. Nevertheless, PES uptake by the private sector remains low, and few studies have analysed whether corporate‐financed PES schemes conform to this rationale. This study evaluates three of the first PES schemes in Thailand, financed by large corporations in the water utilities, aquaculture, and beverage sectors. Interviews with 39 business managers and project stakeholders suggest that PES may be viewed as a tool for philanthropy, public relations, and gaining license to operate—akin to many corporate social responsibility initiatives. Explanations and ramifications are discussed in the context of ecological uncertainty, risk management, financial performance, organisational learning, and the corporate‐engagement strategies of non‐governmental organisations.  相似文献

资本回报率下降对人力资本投资、收入不平等程度有较大影响。本文将可变资本回报率加入Galor-Zeira模型,理论推导发现:收入不平等陷阱并非不可逾越的障碍。当技能劳动力工资高于受教育固定成本时,随着资本回报率下降,接受教育的遗赠临界水平将降低,更多家庭将发现投资人力资本是有利的,稳态的技能劳动力比例将提高。在当前资本回报率下降的大背景下,提高技能劳动力工资、降低受教育成本、对教育贷款实施财政减免优惠、为农村中等教育支出减负和提升农村教育质量、倡导节俭和重视遗赠的文化氛围在长期都有助于提高技能劳动力比重以及缓和收入不平等。  相似文献

Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.  相似文献
