The aim of this study is to investigate the relationship between free cash flows and escalation behavior in the long-term stock buying decisions for the firms listed in Taiwan. The main findings include: (1) Managers tend to exhibit the escalation behavior in the long-term equity investment. (2) There is a positive association between the level of free cash flows and the magnitude of managers’ behavioral escalation. (3) The corporate governance mechanisms play a contributory role in mitigating the escalation behavior. The evidence is robust across subsamples for electronic versus non-electronic industries, growth versus value firms, and loss versus gain firms. 相似文献

This study examines the association between fair value measurements and the cost of equity capital under different fair value valuation methods, and assesses the impact of corporate governance on this relationship for US financial firms. We find that firms’ cost of equity capital is negatively associated with more verifiable fair value assets and positively related to less verifiable fair value assets. Furthermore, the positive association between less verifiable fair value assets and the cost of equity capital is mitigated under better corporate governance. The differential impact between more and less verifiable assets becomes smaller for firms with stronger governance. Our findings contribute to the ongoing debate on fair value regulation by investigating the economic consequences of adopting Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157) and the importance of audit committee financial expertise on fair value reporting. We also provide evidence on the importance of board independence, internal control strength, auditor industry specialists, and audit committee financial experts in fair value reporting. 相似文献

This study assesses distorting effect of financial constraints on the inverse relationship between internal and external finance by examining impact of an exogenous financing shock (i.e. a regulation released in China in 2008) on dividend policies in a quasi‐natural experimental setting. Our result shows that in the absence of the regulation, the inverse relationship holds. However, the relation is twisted by the 2008 regulation. Compared with unconstrained firms, financially constrained firms are more willing to pay dividends and are more restrained to reduce cash dividends after the regulation, despite the fact that their external financing capacities are further constrained. 相似文献

We develop two models of the relationships between emotional intelligence (EI), job insecurity, and psychological strain. The moderation model suggests that EI reduces psychological strain by helping individuals cope with job insecurity when it arises. The mediation model suggests that EI reduces psychological strain by enabling individuals to conserve resources, thereby reducing their experience of job insecurity. Our results, based on a sample of 232 real estate agents, show that job insecurity mediates the relationship between EI and psychological strain. Contrary to what the moderation model suggested, the positive relationship between job insecurity and psychological strain was found to be stronger when EI was higher. Overall, the results provide more nuanced insights into the role of EI in psychological strain. 相似文献

产业结构优化升级改进生态效率了吗? 总被引:9,自引:0,他引:9
建立广义动态空间面板计量模型,从本地效应和区际互动双重视角分析产业结构优化升级对省份生态效率影响的驱动机理和作用效果。研究发现,产业结构高度化既能提高本省份也能提高其他省份的生态效率,即存在本地和外部双重正面效应;而产业结构合理化对生态效率则更多体现为正外部效应。从异质性上看,经济发展水平的提高,更加有利于合理化本地正面效应以及高度化双重正面效应的发挥;合理化和高度化与环境规制的相互作用,更有利于本省份生态效率的提高。 相似文献

本文基于中国工业企业—对外直接投资匹配数据,以加成率为视角,运用倍差法对中国对外直接投资企业的盈利能力进行了考察。通过检验我们得出如下几点经验证据:对外直接投资(ODI)当期会降低企业加成率;ODI有显著正向的滞后“加成率效应”,且呈现增长趋势;技术研发和生产加工型ODI具有显著的滞后“加成率效应”;中国对非洲、“一带一路”沿线国家和金砖国家投资有显著超过平均水平的正向滞后效应。 相似文献

Telehealth services provide a means of monitoring a patient’s vital signs through the use of equipment or mobile devices and have the potential to extend clinical outreach to more patients regardless of geographical locations. However, patient acceptance is essentially important for the success of telehealth implementations. Thus, it is of interest to evaluate patients’ attitudes and perceptions toward the use of telehealth services. This study combines service quality model and importance-performance analysis to evaluate telehealth services provided by a case hospital. The results show that six items belong to major weaknesses, which should be addressed immediately in order to reduce patients’ complaints. In contrast to major weaknesses, there are seven items classified as major strengths, which should be maintained to provide telehealth service excellence in order to establish better and longer relationships with patients in the long-term perspectives. 相似文献

自2014年6月证监会重启员工持股计划以来,已有超过8%的上市公司推出员工持股计划预案。以2010—2017年A股上市公司为研究样本,基于多时点DID研究框架,用以控制可能存在的内生性问题。实证检验企业实施员工持股计划(ESOP)对企业创新活动的影响效果,以此揭示中国混合所有制改革背景下实施员工持股计划(ESOP)的真实效果。结果发现:实施ESOP的企业相较于未实施ESOP的企业具有更高的创新产出,并且在信息透明度更高的企业中这种促进作用更显著;相比于国有企业,在非国有企业实施ESOP对创新活动的促进作用更强。进一步通过中介效应对机制进行检验发现,实施ESOP后可以提高管理层创新意愿进而促进创新投入。研究揭示了ESOP对企业创新活动影响可能存在的作用机制,对广大投资者理解ESOP公司治理作用具有一定启示意义。 相似文献
