This study examines the link between information spread by social media bots and stock trading. Based on a large sample of tweets mentioning 55 companies in the FTSE 100 composites, we find significant relations between bot tweets and stock returns, volatility, and trading volume at both daily and intraday levels. These results are also confirmed by an event study of stock response following abnormal increases in the volume of tweets. The findings are robust to various specifications, including controlling for traditional news channel, alternative measures of volatility, information flows in pretrading hours, and different measures of sentiment. 相似文献

Politicians frequently intervene in the regulation of financial accounting. Evidence from the accounting literature shows that regulatory capture by special interests helps explain these interventions. However, many accounting rules have broad economic or social consequences, such as their effects on income distribution or private sector subsidies. The perception of these consequences varies with a politician's ideology. Therefore, if accounting rules produce those consequences, ideology plausibly spills over and explains a politician's stance on the technical accounting issue, beyond special interest pressure. We use two prominent U.S. political debates about fair value accounting and the expensing of employee stock options to disentangle the role of ideology from special interest pressure. In both debates, ideology explains politicians’ involvement at exactly those points when the debate focuses on the economic consequences of accounting regulation (i.e., bank bailouts and top management compensation). Once the debates focus on more technical issues, connections to special interests remain the dominant force. 相似文献

Resource Dependence and Network Relations: A Test of Venture Capital Investment Termination in China 下载免费PDF全文
This study examines how venture capital (VC) firms terminate investments in an emerging economy context. We contend that due to the weak institutional environment, it is appropriate to draw on insights from power and social relation perspectives for a better understanding of the phenomenon. Specifically, we argue that a termination decision hinges on not only the dependence relationship between a VC firm and its portfolio companies, but also the social relationships among VC firms. Event history analyses of approximately 12,000 VC deals made in China between 2001 and 2012 reveal that when a VC firm has a greater number of investments in an industry, it is more likely to terminate investments on a portfolio company in that industry. Moreover, such effect on termination is moderated by the focal VC's embeddedness with its syndicate partners and collaboration opportunities with other VC firms outside the immediate access of the syndicate partners. Our study sheds light on research on VC decision making in emerging markets by integrating insights from resource dependence relationships and interorganizational network characteristics. 相似文献

AbstractDrawing insights from the group engagement model and self-determination theory, our research explored the role of perceived empowerment human resource (HR) practices in the hybrid organizational form of social enterprise in China. Based on two studies, this paper developed and examined a moderated mediation model, linking perceived empowerment HR practices, identification motivation, work engagement, and authority work value. Specifically, in Study 1 we found perceived empowerment HR practices increased employees’ work engagement through enhancing employees’ identification motivation. In Study 2, we adopted a two-wave design to duplicate and extend this mediation model. A moderator, employees’ authority work value, was found to weaken both the mediation relationship, and the positive relationship between perceived empowerment HR practices and identification motivation. This study broadens the understanding of what social enterprises look like in alternative contexts, while providing an opportunity to explore how a HRM mechanism and its boundary condition function in large social enterprises in China. 相似文献

An online survey of 1,201 U.S. residents was conducted in April 2015 to better understand individuals’ perceptions of prominent areas of corporate social responsibility (CSR) in the food supply chain. Demographic and household consumption information, including supermarket patronage, was collected. Each respondent completed best–worst tasks for CSR areas designed to elicit their relative importance of CSR areas. Overall, health and safety were perceived as the most important CSR area, and environment was prioritized second. Indicating gender as female and/or reporting age over 65 was positively correlated with the relative importance placed on health and safety, but negatively correlated with the size of preference share for nearly all other CSR areas investigated. Membership in the younger age categories was positively correlated with the size of the preference shares devoted to procurement, labor, fair trade, and biotechnology. 相似文献

Netnography is constantly evolving as technologies and access to online data develop. Our paper outlines how large data sets of social media can be analysed through bridging the divide between the small, rich and contextually nuanced data that is the hallmark of netnography and the scope and scale of data made possible through social media listening conventions. We define this approach as netnographic sensibility and with the use of a short case study discuss the process through which social media data could be gathered, triangulated and analysed. We orientate the paper around two interrelated questions: investigating how netnographic insights can be extended using social media monitoring tools, and asking how this can be used to add richness and depth to understanding mass consumer realities. Our contribution complements the widely established methodological approach of netnography as we argue that netnography has the capacity and capability to embrace technological advances within the domain of social listening to add value for academic researchers. 相似文献

Research Summary: While prior studies have predominantly shown that CEO narcissism and hubris exhibit similar effects on various strategic decisions and outcomes, this study aims to explore the mechanisms underlying how narcissistic versus hubristic CEOs affect their firms differently. Specifically, we investigate how peer influence moderates the CEO narcissism/hubris—corporate social responsibility (CSR). With a sample of S&P 1500 firms for 2003–2010, we find that the positive relationship between CEO narcissism and CSR is strengthened (weakened) when board‐interlocked peer firms invest less (more) intensively in CSR than a CEO's own firm; the negative relationship between CEO hubris and CSR is strengthened when peer firms are engaged in less CSR than a CEO's own firm. Managerial Summary: Some CEOs are more narcissistic while others may be more hubristic, but these two groups of CEOs hold different attitudes toward the extent to which their firms should engage in corporate social responsibility (CSR). Our findings with a large sample of U.S. publically listed firms suggest that narcissistic CEOs care more about CSR, but hubristic CEOs care less. Interestingly, when narcissistic CEOs observe their peer firms engaging in more or less CSR than their own firms, they tend to respond in an opposite manner; in contrast, hubristic CEOs will only engage in even less CSR when their peers also do not emphasize CSR. Our findings point to a fundamental difference between CEO narcissism and hubris in terms of how they affect firms' CSR decisions based on their social comparison with peer firms. 相似文献

通过对贵州、广东和福建3个省80家企业1148名员工进行调研,基于员工对企业社会责任、领导行为感知对人力资源管理效能带来积极影响为研究问题构建了一个中介模型。企业社会责任在组织微观层面的内涵越来越得到企业的重视,实现了员工的企业社会责任由产出需求转向投资视角,成为企业满足员工工作需要和工作资源的参照标准体系,有利于提升企业人力资源管理效能。本文研究发现:企业社会责任分别从企业经济责任、法律责任、伦理责任和自行裁量责任影响人力资源管理效能;变革型领导和交易型领导对企业社会责任和人力资源管理效能具有协同中介作用。研究结论对于企业社会责任、领导行为和人力资源管理三者匹配具有重要的理论和现实意义。 相似文献

ABSTRACT While most consumers today feel concerned by environmental issues, the consumption of hot beverage in disposable cups remains very important. In this study, we use influence strategies related to social norms to reduce these behaviors and get consumers to consume their hot beverage in reusable cups. 14373 orders were analyzed and demonstrate that normative messages can be effective to change consumer behavior toward a more responsible choices. 相似文献
