Positive spillover effect and audit quality: a study of cancelling China’s dual audit system

The mandatory dual‐audit and dual‐reporting system (DADRS) for mainland Chinese firms cross‐listed in Hong Kong (AH firms) was abolished in 2010. This study quantifies a positive spillover effect from Hong Kong‐based auditors in the DADRS and examines whether and to what extent this affects the audit quality of AH firms. We find that AH firms exposed to a stronger positive spillover effect have higher audit quality, and the loss of this effect drives the declining audit quality of AH firms after they cancelled the DADRS. This study is among the first empirical works on this research topic.     

Dismantling the myths about managerial (in)capabilities in micro-firms. SEAM intervention-research to develop management practices

Extant literature on SMEs currently offers an incomplete and deterministic characterisation of micro-firms (M-Fs) that are not growth-oriented start-ups, so very little is known about the actual functioning and internal challenges that hinder the adoption of management practices of these companies, and how to facilitate their management development. Using the Socio-Economic Approach to Management (SEAM) as theoretical lens and SEAM intervention-research as methodology, the study uncovers myths in the managerial characterisation of micro-firms and suitable patterns of change management practices for them. Our research contributes to the study of M-Fs by being the first study specifically devoted to mature M-Fs, and by proposing a theoretical framework that shows the dynamic nature of the characteristics associated with M-Fs.     

When does breach not lead to violation? A dual perspective of psychological contract in hotels in times of crisis

Implicit psychological contract (PC) represents the dynamic employee–employer relationship, and unlike explicit human resource (HR) practices, PC is an underexplored topic in the crisis management literature. By capturing the dual perspective of hotel employers and employees through interviews, this study investigates the content of PCs and breaches of PCs during the COVID-19 pandemic crisis. The study identifies salient dimensions of employer obligations such as safety assurance and of employee obligations such as personal protection. While employees emphasized the transactional contracts to protect their individual interests, the employers tried to balance the transactional and relational contracts. The study proposes a dynamic PC breach model that indicates contract breaches lead to varied responses through a complex interpretation process. In general, the study suggests that ensuring mutual consideration is the best way for hotel employees and employers to pull through a crisis.     

自然教学法的理论基础及在大学英语阅读教学中的应用

非平稳条件下的市场可预测性问题研究

本文研究了非平稳对线性、非线性可预测性检验的影响,从非平稳角度解释了"非线性可预测性难题"。在此基础上对传统的Box-Pierce-Ljung线性检验法和广义谱密度非线性检验法进行了修正,并运用严格的理论证明和蒙特卡罗模拟证实了它们在大样本和有限样本情况下的非平稳稳健性。最后,运用修正的检验方法对我国第一只股指期货标的沪深300统一指数的可预测性进行了分析。本文结论对于我国金融市场实证研究具有重要的指导意义,也反映了我国新兴金融市场的独有特性以及成熟统计方法在我国的实用性。     

期权定价数值分析模型的计算机程序实现探讨

由于复杂的、多维度期权的应用越来越广泛,运用数值分析方法对其进行定价分析已成为一个必不可少的手段。然而,数值分析方法自身运算的复杂性,决定了其手工运算的成本高,因此充分发挥计算机的"精确、快速"优势是实现期权定价数值分析模型的一个必然趋势。基于计算机编程语言技术,研究了Java对数值方法的实现,及Java语言在期权定价中的应用;并通过java语言本身的语法规则、内嵌函数等,对期权定价的二叉树模型和蒙特卡罗模拟方法进行有效的实现。研究结果表明,运用java语言可以较快、较好地解决规则期权与奇异期权的定价问题。     

二元所得税的兴起:国际经验及启示

二元所得税作为一种对资本所得与劳动所得分离课税的个人所得税新模式,已被越来越多的国家所尝试。围绕二元所得税,理论界的争议主要集中于对资本所得征税的效率性、公平性、管理性和普及性等方面。对我国而言,既要反思劳动所得和资本所得的差异,明确个人所得税改革的基本思路与方向,又要采取渐进主义的改革策略,设计二元所得税的短期、中期和长期目标,在条件成熟时予以尝试。     

CEO自恋对企业成长的作用机制研究

在开发管理者自恋人格量表基础上，调研CEO自恋受访对象与其所在企业年度数据，实证研究CEO自恋、双元创新与企业成长之间的作用关系。研究表明：CEO自恋对企业利用式创新和企业成长均有显著正向影响，但是对探索式创新影响不显著；企业利用式创新在CEO自恋与企业成长中存在部分中介效应。
