How the COVID-19 pandemic affected hotel Employee stress: Employee perceptions of occupational stressors and their consequences

This study sought to examine the impacts of the global coronavirus pandemic on hotel employees’ perceptions of occupational stressors and their consequences. Paired t-tests and structural equation modeling were applied to examine the responses of 758 hotel employees in the United States. The findings showed that occupational stressors after the outbreak of the pandemic consisted of three domains: traditional hotel-work stressors, unstable and more demanding hotel-work-environment stressors, and unethical hotel-labor-practices-borne stressors. The impacts of these stressors differed from the hypothesis that traditional hotel-work stressors positively affect job satisfaction and organizational commitment. The findings showed that job satisfaction and organizational commitment significantly explained job performance, subjective well-being, and prosocial behavior, but they did not significantly influence turnover intention. Hotel employees’ pre-pandemic perceptions of occupational stressors and their consequences also differed significantly from their perceptions after the pandemic had broken out.     

优化营商环境与外资企业FDI动机——市场寻求抑或效率寻求

在优化营商环境已成为当前发展中国家引资竞争新优势的背景下,针对优化营商环境影响外资企业FDI动机的考察变得尤为重要。本文在构建企业层面营商环境指数的基础上,考察了发展中国家优化营商环境影响外资企业FDI动机的机制及效应。结论表明:优化营商环境减弱(增强)了外资企业的市场(效率)寻求型FDI动机;内资企业竞争力的增强、外资企业特惠资源的取消和加工贸易型外资企业的存在,使得优化营商环境降低了外资企业的生产率,进而市场(效率)寻求型FDI动机减弱(增强)。细分样本的考察发现,上述结论仅存在于独资企业、工业和低收入国家的外资企业中,对于合资企业、服务业和高收入国家的外资企业,优化营商环境对其FDI动机无显著影响,且生产率的中介效应不存在。本研究从优化营商环境的视角为当前中国引资政策的制定提供了更为具体的政策启示。     

渠道合作情境下合同双元功能对主动和被动投机行为的影响差异研究

基于交易成本理论，在渠道合作情境下，以制造商的合同监督和企业间联合行动为工具测量合同治理的保障功能和协作功能，探讨二者对经销商主动投机行为和被动投机行为的影响差异。通过对512份问卷数据的统计分析，得到以下结论：第一，合同监督有助于抑制经销商的主动投机行为，但对其被动投机行为的影响不显著；第二，企业间联合行动有助于抑制经销商的被动投机行为，但对其主动投机行为的影响不显著；第三，经销商的主动投机行为和被动投机行为均会负向影响合作绩效；第四，经销商的主动投机行为中介合同监督对合作绩效的正向影响，被动投机行为中介企业间联合行动对合作绩效的正向影响。     

National response strategies and marketing innovations during the COVID-19 pandemic

During the COVID-19 pandemic, different nations have adopted a variety of response strategies to fight and contain the new coronavirus. Such national response strategies can be classified into three categories based on their underlying philosophy: strict control with unlimited resources, relentless contribution with limited resources, and rough rationality with limited resources. We discuss the philosophies, characteristics, and performances of the three response strategies and when they should be adopted. We also examine what marketing innovation strategies enterprises should adopt to survive and grow their businesses in both the short and long term. This study provides important strategic implications for national policymakers and enterprises on the use of response strategies as well as marketing innovation tactics and strategies to be used both during and after the pandemic.     

Exploring the links among corporate social responsibility,reputation, and performance from a multi-dimensional perspective

This study examines the links among corporate social responsibility (CSR), reputation, and performance in hotel companies from a multidimensional perspective. Data were collected from 322 hotels in China and partial least squares equation modelling (PLS-SEM) was employed for a causal-predictive analysis. Study results reveal that CSR practices influence hotel reputation as seen from both international and local perspectives. CSR and reputation influence performance dimensions (accounting-based performance, market-based performance, and non-financial performance) differently. The research findings offer specific theoretical and practical implications for hotel managers.     

Excessive managerial entrenchment,corporate governance,and firm performance

This paper investigates the differential impact of positive and negative excessive managerial entrenchment on the CEO turnover-performance sensitivity, CEO compensation, and firm performance. We measure the degree of managerial entrenchment using the E-index introduced by Bebchuk et al. (2009). Our findings suggest that an increase in excess CEO entrenchment reduces the likelihood of CEO turnover due to poor performance. We also show a positive association between excessive entrenchment and CEO compensation as managers gain more power and authority when they are entrenched. On the other hand, excess CEO entrenchment has an inverse correlation with firm performance and firm value. Overall, we propose that excessive managerial entrenchment has a converse impact on board monitoring and shareholders’ welfare.     

Deep learning for modeling the collection rate for third-party buyers

This study evaluates a wide range of machine learning techniques such as deep learning, boosting, and support vector regression to predict the collection rate of more than 65,000 defaulted consumer credits from the telecommunications sector that were bought by a German third-party company. Weighted performance measures were defined based on the value of exposure at default for comparing collection rate models. The approach proposed in this paper is useful for a third-party company in managing the risk of a portfolio of defaulted credit that it purchases. The main finding is that one of the machine learning models we investigate, the deep learning model, performs significantly better out-of-sample than all other methods that can be used by an acquirer of defaulted credits based on weighted-performance measures. By using unweighted performance measures, deep learning and boosting perform similarly. Moreover, we find that using a training set with a larger proportion of the dataset does not improve prediction accuracy significantly when deep learning is used. The general conclusion is that deep learning is a potentially performance-enhancing tool for credit risk management.     

险资股权投资的结构性改革研究*——基于险资投资的倒U型效应分析

保险资金作为重要的机构投资者能否发挥促进公司绩效提升的作用在已有研究和监管政策制定上都存在较大争议。本文以2005-2017年A股上市公司为研究样本，发现险资持股比例对上市公司绩效以及估值影响存在显著的倒U型曲线效应，相应机制研究表明险资持股通过显著影响两类代理成本的渠道发挥治理作用。在适度持股比例以下，险资增持能够降低被投资公司管理费用率和其他应收款占比，并提高资产周转率，从而降低两类代理成本；持股超过一定比例反而造成两类代理成本上升。险资持股比例变化对保险机构调研次数的影响则从公司治理参与角度印证了以上结论。对倒U型曲线效应的深入分析既有助于深化对机构投资者影响公司绩效的多重效应和机制的认识，同时为在金融机构层面落实金融供给侧结构性改革、增强险资服务实体经济能力提供参考。     

国有股权参股对家族企业创新效率影响机制与路径研究

在混合所有制改革和创新驱动发展战略实施背景下，国有资本“举牌”民营企业对企业创新体系的作用机制亟待研究。基于2008-2018年上市家族企业数据，从创新投入和创新产出两个视角探讨国有股权参股对家族企业创新效率的影响，根据股东资源理论分析可能的影响路径。通过Heckman两阶段模型实证发现：国有股权参股显著促进家族企业创新投入和创新产出，并最终对创新效率产生积极影响，而获取政府补贴和提升创新管理能力是两条中介路径。该结论揭示了混合所有制改革在激发民营企业创新活力中所发挥的重要作用和影响机制，为家族企业提高创新效率提供了新方向。
