资产证券化的会计处理

资产证券化凭其独特的构思和精妙的结构，既使发起人获得所需资金同时又有效地分散了资产支持证券的风险，因此成为当前国际金融市场上的宠儿。但是伴随资产证券化的广泛应用，出现了资产证券化的会计处理难题。本文从分析资产证券化的概念、特征入手，结合我国资产证券化的实际情况，探讨资产证券化的会计处理。     

个人所得税地区间汇算清缴方法研究

综合与分类相结合的个人所得税制改变了个人所得税按来源地缴纳和分享的模式。个人综合所得的所得税征收时实行预扣预缴和次年汇算清缴制度。当个人综合所得来源于多个地区时,需要在不同预扣预缴地区间进行汇算清缴。如何在不同收入来源地分配税收成为地区间汇算清缴制度设计的重要关键。本文首次从税收创造和税后收益分配角度,建立了两个税收分配的合作博弈模型。比较分析发现,使用解决"破产问题"的方法都是把地区的所得和总税收作为给定的参数,没有考虑地区所得和税收之间的生成关系和累进税率。我们的研究证明夏普利值作为合作博弈的解,具有公平性、效率性和单调性,是个人所得税地区间分配方式的合适选择。     

项目总控的应用及其信息处理规划

随着国内大型建设项目的增多，大型建设项目的实施遇到诸多问题，其原因主要是业主对项目的控制能力不强，从而导致大型建设项目不能实现其质量、进度、投资等预期目标，甚至会导致整个项目的失败，项目总控模式的应用很大程度地解决了这一问题，另外，由于信息处理是项目总控的主要工作，因此，本也讨论了项目总控模式下的信息处理规划。     

Annual report readability and corporate agency costs

Annual reports are the main sources of information for outside investors’ investment decisions and enable shareholders to supervise the management. Difficulties with the readability of these reports may therefore have serious consequences. Using 19,221 firm-year observations of Chinese A-share listed firms from 2001 to 2015, we investigate the association between annual report readability and corporate agency costs, where readability is proxied by report file length and/or file size. We find that firms with better annual report readability experience lower agency costs, and the negative association between readability and agency costs is more pronounced in firms with higher external audit quality, internal control quality or analyst coverage. These results hold after several robustness checks. The positive effect of annual report readability is stronger in private firms than in state-owned enterprises, and becomes stronger after the implementation of new accounting standards in 2007. Readable annual reports can help in monitoring corporate insiders’ opportunistic behavior and thus reduce agency costs.     

辽宁上市公司董事会报告透明度影响因素研究

以46家辽宁上市公司为样本,对影响董事会报告透明度因素的研究发现:股权集中度、管理层持股比例、董事会规模、独立董事比例与董事会报告透明度呈正相关关系;股权制衡度,董事长与总经理是否两职合一,审计意见类型与董事会报告透明度呈负相关关系。上市公司应该通过股票期权等方式提升管理人员的持股比例,激励他们积极治理公司,提高董事会报告信息披露的透明度;上市公司第二大股东应适度提高持股比例,防止一股独大现象;同时减少董事长与总经理两职合一,也会有助于提高董事会报告的透明度。     

企业社会责任表现、报告质量与企业声誉——基于中国上市公司的实证研究

近年来，越来越多的企业通过发布企业社会责任（CSR）报告与利益相关者沟通CSR表现的情况。在CSR与企业声誉之间的关系备受关注的背景下，CSR报告质量在其中发挥着什么样的作用呢？梳理现有文献，将CSR表现划分成责任管理、市场责任、社会责任以及环境责任，通过实证检验，分别探讨各自与企业声誉之间的作用机理，并研究CSR报告质量在二者之间关系中的调节效应。研究结果显示CSR表现正向作用于企业声誉，相较于责任管理，责任实践的正向作用更强。同时CSR报告质量在二者之间的关系中具有调节效应，能够进一步提升企业声誉，并且对环境责任的调节效应最为明显。

Bankruptcy prediction for small- and medium-sized companies using severely imbalanced datasets

Bankruptcy prediction is still important topic receiving notable attention. Information about an imminent bankruptcy threat is a crucial aspect of the decision-making process of managers, financial institutions, and government agencies. In this paper, we utilize a newly acquired dataset comprising financial parameters derived from the annual reports of small- and medium-sized companies. The data, which reveal the true ratio between bankrupt and non-bankrupt companies, are severely imbalanced and only contain a small fraction of bankrupt companies. Our solution to overcome this challenging scenario of imbalanced learning was to adopt three one-class classification methods: a least-squares approach to anomaly detection, an isolation forest, and one-class support vector machines for comparison with conventional support vector machines. We provide a comprehensive analysis of the financial attributes and identify those that are most relevant to bankruptcy prediction. The highest prediction performance in terms of the geometric mean score is 91%. The results are validated on two datasets from the manufacturing and construction industries.     

Strategic insider trading around earnings announcements in Australia

This paper tests, within the Australian setting, whether directors strategically time trades in their own firms, around earnings announcements, in the context of impediments to trading in the immediately preceding period. I show that both signed and unsigned trade activity are insignificantly different from zero in the preceding period, and significantly negative and positive after the event. Further, directors in Australia significantly sell following positive earnings news, and buy after negative news, providing evidence of ‘indirect’ trading. Directors’ trades in the longer-term pre-announcement period are also negatively related to the news content sentiment, contrary to expectation. Finally, I find evidence of positive autocorrelation between directors’ trades over the longer-term past, and those executed after earnings announcements, which, in the absence of the ‘short-swing’ rule in Australia, casts doubt over short-term strategic insider trading, more generally.
