Environmental Policy,Rankings and Stock Values

This paper examines the impact of Newsweek's ‘The Greenest Big Companies in America’ on stock values for large companies. Newsweek ranks the biggest Companies in America from one to 500. An event window of ten days following the rankings release to the public was examined to analyze the impact of relative rankings on stock values. Dummy variables were constructed denoting firms ranked in the highest and lowest quartiles. Control variables included return to the Dow Jones Industrial Average, the firm's beta coefficient and total revenue. The main finding of the study is that inclusion in the top quartile of the rankings has a positive and statistically significant impact on firms' stock values, while the coefficient for the lowest quartile was not statistically different from zero. The results provide evidence of a positive impact on stock values from favorable environmental recognition but no effect for low ranked firms.

中美评级机构博弈

国际信用评级市场被美国三大评级机构———惠誉,标准普尔和穆迪垄断,而三大机构的独立性,公正性和前瞻性近些年备受质疑,各主权国家的金融安全和产品定价权受到威胁。中国在国际评级市场中要承担起一个大国的责任,运用博弈论的方法分析中国评级机构能否顺利进入由美国垄断的国际评级市场,针对均衡结果提出对抗垄断的评级市场的建议。     

微型金融评级的特殊性及对我国的启示

微型金融评级以微型金融为基础，是微型金融发展到一定阶段的产物。微型金融的特殊性决定了微型金融评级在评级对象、评级主体、评级方法、评级功能等方面也存在特殊性。随着微型金融的迅速发展，我国应逐步构建微型金融评级体系，并利用现存机构、以标准化方法开展微型金融评级，以推动我国微型金融评级发展。     

A re-examination of the impact of credit ratings and economic factors on state bond yields

In this article we re-examine the impact of credit ratings and economic factors on state bond yields using a two-step model. In the first step, we adopt an ordered probit technique to obtain consistent estimates of state bond default risk. In the second step, we estimate state bond risk premiums using a regression analysis with a categorized risk variable obtained from the first step. Similar to Terza (1987) and Hsiao (1983), the model involves a categorized ordinal explanatory (rating) variable. However, our two-step model deals with a case where category thresholds are unknown and dependent on economic factors. The model provides consistent estimates for the effects of ratings and economic factors on state bond yields. Contrary to previous findings, we find that state bond yields are mainly affected by fundamental economic variables.

制度创新与社会信用

信用是现代市场经济的基石,也是优化资源配置的有效手段。本文认为,造成我国信用缺失的原因是多方面的,有认识上的原因,也有法律制度不健全、对失信行为处罚力度不够等原因,但最主要的原因是产权制度不完善。因此,进行制度创新,完善产权制度,是建设现代市场经济社会信用的必要条件,也是规范市场经济秩序的治本之策。     

"退而更化":中国合作金融的改良之路

合作金融的现代化从社会哲学上看,涉及到如何处理现代化与传统之间的紧张关系;涉及到否定传统、移植西方体制的思维方式对错的问题.从回答这个基本社会哲学问题入手,检讨中国传统合作金融组织——舍会的珍贵遗产,申明白愿原则是合作金融的灵魂以及这个灵魂对当今中国合作金融的改良所具有的价值.在此基础上,本文提出了以组建中国农村合作银行为核心的政策建议,而中国农业银行出售非农业务、回归农村,与农村信用社进行资本重组与业务整舍,是现实可行的一条最佳途径.     

Information reduction via level crossings in a credit risk model

This paper provides an alternative credit risk model based on information reduction where the market only observes the firm’s asset value when it crosses certain levels, interpreted as changes significant enough for the firm’s management to make a public announcement. For a class of diffusion processes we are able to provide explicit expressions for the firm’s default intensity process and its zero-coupon bond prices.
