Investor Relations （IR） in Business Communication on the Example of Poland

This paper focuses on investor relations （IR） as an element of companies＇ communication with the external environment. It shows the place and role of IR in communication with the general market, and the stock exchange market in particular. The study is illustrated with an example of IR in Poland, a relatively new European Union （EU） member state and an emerging market. As can be seen, IR goes beyond the traditionally understood maintenance of communication with the capital market. It is also shown that the main role of IR ought to be the reduction of investment risk and enhancement of the companies＇ value, which is of particular significance in light of the current globalization of capital markets. It has been found that Polish companies, especially those listed on the Warsaw Securities Exchange （WSE）, commonly rely on IR as a means of communication with the environment. And yet, as the results of the analysis show, the quality of that communication is still far from satisfactory, despite efforts undertaken by various external entities to encourage more focus on the development of IR, or understanding of the company＇s relevant staff of its important role.

会计管制研究梳理及评论

文章主要介绍了国内外学者围绕会计管制的内涵界定、影响因素、经济后果、国际趋同以及公司治理与会计欺诈交叉研究等研究成果。在文献梳理中发现：我国的会计管制研究内容分散且观点存在分歧,仍停留在中心问题的边缘地带,对问题实质之处的挖掘还不够深入。西方理论界对会计管制的研究起步早、范围广,为国内学者提供了理论框架、技术方法等方面的研究指导,安然事件后《萨班斯法案》的出台,更引发了对会计管制的研究热潮。通过对会计管制研究进行脉络梳理和评论,以促进我国会计管制的广角研究。     

实施转融通制度提高了我国证券市场质量吗？——运用双重差分模型对沪深股市的实证分析

以50种纳入转融通标的证券的股票构造处理组,以50种纳入融资融券标的证券但未纳入转融通标的证券的股票构造控制组,利用转融通制度实施前后各10个交易月份的数据,采用双重差分模型研究转融通制度的实施对证券市场流动性、波动性、有效性等市场质量的净影响,得到的可靠结论是：转融通制度在一定程度上提高了证券市场的流动性,显著抑制了证券市场的波动性,显著提高了证券市场的有效性,总体上改善了证券市场质量。监管者应进一步拓宽转融通标的证券的范围,增加转融通标的证券的数量,并对证券进入转融通标的证券之前和之后进行区别对待;交易者在确定交易策略时也应做出正确选择。     

国家审计风险模型构建及其应用研究

审计风险模型是指导审计人员开展审计工作的理论分析出发点。国家审计风险与社会审计风险存在实质性差异。国家审计风险具有风险评估外在压力不足、经济业务活动微观查处责任等特征。从舞弊动因出发,国家审计风险由错误风险、舞弊风险和检查风险构成。应用国家审计风险模型,审计人员应在分析建设项目参与各方舞弊可能性的基础上,从审计成本、审计效率的综合角度考虑确定跟踪审计的介入时间。

Insurance fraud detection: A statistically validated network approach

Fraud is a social phenomenon, and fraudsters often collaborate with other fraudsters, taking on different roles. The challenge for insurance companies is to implement claim assessment and improve fraud detection accuracy. We developed an investigative system based on bipartite networks, highlighting the relationships between subjects and accidents or vehicles and accidents. We formalize filtering rules through probability models and test specific methods to assess the existence of communities in extensive networks and propose new alert metrics for suspicious structures. We apply the methodology to a real database—the Italian Antifraud Integrated Archive—and compare the results to out-of-sample fraud scams under investigation by the judicial authorities.
