The asymmetric relationship between executive earnings management and compensation: a panel threshold regression approach

Prior research shows that chief executive officers (CEOs) are rewarded for their earnings management. We re-examine this issue using a panel threshold regression approach, which allows the effect of earnings management on the CEO compensation to change across the level of earnings management and CEO compensation. Our results show that the effect of CEOs’ discretionary accounting choices on their compensation is not homogeneous across various degrees of earnings management and compensation. In particular, for firms with moderate (inordinate) levels of earnings management and CEO compensation, earnings management is rewarded (penalized).     

中国省域碳排放权分配——基于环境FCAM

考虑CO_2排放的非期望产出特性,以最大化整体平均效率为目标,构建省域碳排放权分配的环境固定成本分摊模型(FCAM)。对世袭制、平等主义和支付能力三种公平分配原则下的省域碳排放权初始分配结果进行加权组合,从而获得综合公平原则下的省域碳排放权分配方案。以基于环境FCAM的分配方案趋同综合公平原则下的分配方案为目标,构建优化模型,以融合效率和公平。2020年省域碳排放权分配结果表明:最终分配方案在达到效率最优的同时,属于"绝对平均",较好地融合了效率和公平;基于强度减排压力和总量减排压力对30个样本省进行分类的结果基本一致。最后,针对四类省区的具体情况提出了相应的减排建议。     

Expected benefits and perceived risks of cloud computing: an investigation within an Italian setting

Over the past several years, cloud computing has increasingly been regarded as able to improve efficiency within organisations. The aim of this study is to address under-investigated issues related to the implementation of cloud computing, with a particular focus on expected benefits and the perception of risks. Towards this aim, on the basis of an adapted version of the technology acceptance model, we carried out a semi-structured survey among first-time cloud computing users to identify expected benefits and perceived risks. The survey of this study included a sample of 130 individuals in 65 enterprises located within Italy. We chose an Italian setting because it is characterised by an increasing number of programmes that emphasise the importance of cloud computing and support its wide dissemination. The findings of this study identify possible areas for improvement within the implementation phases of cloud computing.     

Dynamic causality between the U.S. stock market,the Chinese stock market and the global gold market: implications for individual investors’ diversification strategies

This paper proposes a generalization of the prior VAR and EGARCH model to explore the linkage between returns and volatility transmissions in the U.S. stock market, the Chinese stock market, and the global gold market from 10 July 1996 to 20 July 2018. We found that past returns of the U.S. stock market can predict the current returns of the other two markets, and that significant reciprocal volatility transmission existed within and across all three markets. We further implemented average out-of-sample (OOS) forecasting to show that a risk-adjusted portfolio, such as mean-variance with sample estimator, does not outperform an equal-weighted portfolio. This provides insights for individual investors and helps to explain the ongoing disagreement in the portfolio literature concerning the effectiveness of risk-adjusted portfolios and equal-weighted portfolios when the number of assets is small.     

商业银行操作风险的实证分析

近年来商业银行发生了事关操作风险的一系列大案、要案,逐步引起了人们对操作风险的重视。巴塞尔新资本协议把操作风险列为商业银行面临的三大风险之一,要求把它纳入到资本充足的计算框架内,各国学者和银行业也竭力加强对操作风险的研究和管理。操作风险的度量是操作风险管理的核心,度量方法可分为自上而下法和自下而上法。本文利用基于自上而下法建立的收入模型,使用2002年1季度至2011年1季度的季度数据对深圳发展银行和招商银行的操作风险进行了度量,与基本指标法模型所得结果进行了对比分析,并用两家银行的诉讼、仲裁数据进行了间接的实际验证。研究发现:收入模型比基本指标法模型能更准确的度量操作风险;两个银行的风险水平所占总风险比重符合国际惯例要求;招商银行的操作风险管理水平要高于深圳发展银行。     

欧元区成员国通胀差异成因研究

在欧元区内部,不同国家之间的通胀率存在不容忽视的差别。欧元区各经济体间究竟为什么会存在差别如此之大的通胀率呢?什么因素及在多大程度上影响了通胀率的差异?文章从巴拉萨—萨缪尔森效应、价格的收敛效应、输入性通胀、本国要素市场结构差异、本国财政政策和经济周期等六个方面,使用实证数据和面板数据回归探讨了这些问题。     

基于云模型的供电企业人力资源风险评价

为了掌控供电企业现存的人力资源风险状况,及时规避人力资源风险。本文建立了符合供电企业人力资源特点的人力资源风险评价指标体系。通过层次分析法和线性加权法确定人力资源得分。在对人力资源风险等级划分中,引入云模型。该模型摒弃了以往研究的硬划分,更能体现数据的分布特性。然后对评价对象进行逆向正态云化来获得其云参数,最后利用该云参数进行评价。通过实例证明,该模型能够挖掘出更多隐含的信息,具有可行性和有效性。     

中日蔬菜贸易流量与贸易前景——基于引力模型的研究

中国是世界第一蔬菜生产和出口大国。日本作为中国蔬菜出口的重要市场之一,对中国蔬菜产业的发展影响重大。近些年来,由于中国蔬菜在生产、出口方面的整体竞争力不高、信息渠道不畅,加之日本蔬菜市场瞬息万变、市场准入门槛不断提高等因素,中国蔬菜产业面临着十分严峻的竞争态势。为促进中日两国蔬菜出口贸易的健康发展,应积极实施蔬菜标准化工程,推进中国标准向国际通用标准靠拢;强化公共信息的服务与交流,注重政府高层的沟通和政治博弈;密切关注中国蔬菜产品在日本市场的技术贸易壁垒动态,建立和完善预警机制。     

基于门限分位点回归的条件VaR风险度量

门限分位点回归模型是线性分位点回归模型的改进,是一种更加客观实际的非线性估计方法。利用该模型实证分析了单只股票(民生银行)的条件VaR。选择一种流动性风险指标作为条件,经过分析发现,由门限分位点回归模型得到结果能够更好地描述市场,也能更好地预测市场风险。
