This paper studies firms' financial reporting incentives in the presence of strategic credit rating agencies and how these incentives are affected by the level of competition in the rating industry and by rating agencies' role as gatekeepers to debt markets. We develop a model featuring an entrepreneur who seeks project financing from a perfectly competitive debt market. After publicly disclosing a financial report, the entrepreneur can purchase credit ratings from rating agencies that strategically choose their rating fees and rating inflation. We derive the following core results: (1) More rating industry competition leads to stronger corporate misreporting incentives if ratings are sufficiently precise or if rating agencies assume a gatekeeper role. Under imperfect rating industry competition, (2) agencies' gatekeeper role primarily weakens firms' misreporting incentives, which then influences rating agencies' strategies, and (3) firms' misreporting and rating agencies' rating inflation can be strategic complements when agencies assume a gatekeeper role. (4) Regulatory initiatives aimed at increasing rating industry competition or at weakening rating agencies' gatekeeper role improve investment efficiency as long as corporate misreporting incentives are not significantly strengthened. 相似文献

This paper is the first attempt to analyze Standard & Poor’s unsolicited and solicited ratings by using bond-yield data in Japan. Our findings show that there are differences in firm characteristics between firms seeking solicited ratings and those that receive unsolicited ratings. Firms with solicited ratings have less information asymmetry and are more likely to be owned by foreign investors, generate more revenue from exports, be cross-listed in the US, and have higher firm quality. But, firms with unsolicited ratings pay higher costs for debt, and their bond prices react more strongly to credit-rating changes. Yield spreads for new bonds with unsolicited ratings are higher than those with solicited ratings, because unsolicited ratings have higher information asymmetry, and investors therefore demand higher yields. We find that bond-price reactions to the announcements of unsolicited rating downgrades (upgrades) are negative (positive) and significant, while bond prices do not react significantly to solicited rating downgrades or upgrades. 相似文献

Bond researchers have recently observed that issues with split ratings have yields more closely resembling the yields on bonds with the lower of the two ratings. This evidence could lead researchers to question why an issuer ever obtains more than one rating in an environment where two ratings, when split, can never reduce yields, whereas two ratings, when split, can increase yields. This paper explores the rating function in a certification framework and concludes that investors value a second rating. Bond issues with two identical ratings have yields significantly less than issues receiving that rating from only one rating agency. 相似文献

This is the first study to use daily data from a major capital market outside of the US to examine the role of corporate bond and commercial paper rating changes on common stock returns. Using data published by Standard and Poors' credit rating agency between 1984 and 1992, we examine the impact of new credit ratings, credit rating changes and Credit Watch announcements on UK common stock returns. We find significant negative excess returns around the date of a downgrade and positive returns close to the date of a positive CreditWatch announcement. Hence, the financial markets would appear to place some importance on rating agency pronouncements in the UK. New ratings, whether short or long-term, have no significant impact on returns. We also attempt to quantify the impact of a new credit rating upon firm cost of capital through measures of conditional volatility and systematic risk. However, we find only weak evidence to suggest that a stock's cost of capital is reduced after a long-term credit rating is awarded for the first time. 相似文献

信用评级机构虚高评级以及频繁下调主权评级等行为造成并加剧了金融市场动荡,各国政府以及实务界要求加强信用评级监管。美国明确了SEC对信用评级的监管责任,要求促进信用评级业的竞争,并认为评级机构应当适用于与审计师类似的法律责任和公共监管。欧盟对信用评级的监管也由遵守或解释模式转向行政监督。我国需要优化配置政府监管与评级机构对金融市场风险的监管权力界限,发挥各自监管优势,利用信用评级降低信用违约发生的概率,防止金融网络传播或放大信用风险;避免法规对信用评级的援引,激励大型金融机构发挥其在风险管理中的判断能力;加强对结构性金融产品基础资产信用风险和具体契约特征相关风险评级监管;探索利用双评级、投资者付费等模式以及评级机构声誉机制等提高信用评级的准确性,促进我国信用评级业的发展。 相似文献

This paper investigates split credit ratings awarded by Moody's and Standard & Poor's (S&P) to U.S. corporations. Bivariate probit model estimates, analyzing 5,238 firm‐year observations from dual‐rated S&P 500/400/600 index‐constituent corporations, indicate firm‐specific financial and governance characteristics predict split ratings. Large, profitable companies with enhanced interest coverage, a greater percentage of independent directors, and more institutional investment are less likely to receive splits. Moody's appears more conservative in its evaluations, assigning lower ratings to smaller, less profitable companies with low interest coverage. Moody's also associates external, independent constraints on managerial autonomy with a higher corporate credit standing relative to S&P. 相似文献

During the recent Southeast Asian financial crisis, numerous banks failed quickly and unexpectedly. This study uses a unique data set provided by Bank Indonesia to examine the changing financial soundness of Indonesian banks during this crisis. Bank Indonesia's non-public CAMEL ratings data allow the use of a continuous bank soundness measure rather than ordinal measures. In addition, panel data regression procedures that allow for the identification of the appropriate statistical model are used.We argue the nature of the risks facing the Indonesian banking community calls for the addition of a systemic risk component to the Indonesian ranking system. The empirical results show that during Indonesia's stable economic periods, four of the five traditional CAMEL components provide insights into the financial soundness of Indonesian banks. However, during Indonesia's crisis period, the relationships between financial characteristics and CAMEL ratings deteriorate and only one of the traditional CAMEL components—earnings—objectively discriminates among the ratings. The panel data results indicate systemic economy-wide forces must be explicitly considered by the rating system. 相似文献

国际信用评级制度已有一百多年的历史,评级是关于评级对象未来违约概率的估价,随着市场经济的发展和经济运行不确定性的增强,信用评级在社会经济金融活动中发挥着越来越重要的作用。从经济学角度讲, 信用评级的作用主要表现为:一是解决投资与筹资(债务人)之间的信息不对称,减弱投资风险;二是向投资提供筹资(债务人)或某一机构的违约概率,评价其履行金融义务的能力;三是拓宽债务发行(筹资)的融资渠道,帮助其降低筹资费用。由于信用评级机构的评级活动和行为模式不受股东的影响、评估对象的压力和政府的干预,具有较高的独立性、而且依靠专业技术和内部管理来保证其资信评估的客观性,所以信用评级尤其是权威评级机构的评级结构具有较高的可信度,从而,信用评级的服务范围和服务领域不断扩展。 相似文献

I examine effects of a health care system's policy to publicly disclose patient ratings of its physicians. I find evidence that this policy leads to performance improvement by the disclosed, subjective ratings and also by undisclosed, objective measures of quality. These effects are consistent with multitasking theory, in that physicians respond to the disclosure by providing more of a shared input—time with patients—that benefits performance by ratings and underlying quality. I also find, as predicted by information cascade theory, that the ratings become jammed to some degree near initially disclosed values. Specifically, raters observe the pattern of initial ratings and follow suit by providing similar ratings. Finally, I find evidence that physicians anticipate rating jamming and so concentrate their effort on earlier performance in order to set a pattern of high ratings that later ratings follow. These results demonstrate that the disclosure of subjective ratings can benefit performance broadly but can also shift effort toward earlier performance. 相似文献

The gross price elasticity of demand for medical care is decomposed into two separate observable components: the medical care gross price elasticity of insurance choice and the cost-sharing elasticity of medical care. When consumers alter their choice of health-care plans, the price elasticity of medical care is no longer equivalent to the cost-sharing elasticity; using the latter as a proxy for the former may produce misleading results. We present conditions under which the medical care price elasticity is positive , the case of a quasi-Giffen good, and provide a theoretical foundation for extant empirical findings of a positive medical care price elasticity of insurance demand. 相似文献

Rating Agencies as Gatekeepers to the Capital Market: Practical Implications of 40 Years of Research
This paper gives an extensive overview on the avenues academic research has taken in exploring the role of credit ratings. In doing so, it relies on a strict methodological approach for the collection and evaluation of relevant studies to address the criticisms on the lack of profoundness in prior literature reviews in business research. It provides therefore to both academics and practitioners an exhaustive compendium on the role and relevance of credit ratings for each key stakeholder over the past 40 years. Second, it pinpoints specifically to how credit ratings impact corporate strategy. In this matter, it suggests to focus on this underresearched aspect in future as it has become a critical factor in the decision‐making of company boards. 相似文献

与通货膨胀一样,评级膨胀具有持久的、螺旋上升的和影响深远的危害性。信用评级在本质上只是一个相对风险措施,典型的信用评级并不能完全反映宏观经济周期。对国家和投资者来说,信用评级所导致的风险与威胁主要来自于"信用评级膨胀"。而究其根本,评级膨胀的大规模泛滥最终得益于美国两大评级机构的双评级规范霸权,以及由美国评级机构所垄断的国际评级网络。由于存在激励促使他们逃避基于评级的监管,因此道德风险在所难免,并一定会催生评级膨胀。因此,评级膨胀只是表象和媒介,双评级规范和网络效应才是美国评级霸权的最终顶点。 相似文献

We propose a theory of reputation to explain how investors rationally respond to mutual fund star ratings. A fund's performance is determined by its information advantage, which can be acquired but decays stochastically. Investors form beliefs about whether the fund is informed based on its past performance. We refer to such beliefs as fund reputation, which determines fund flows. As performance changes continuously, equilibrium fund reputation may take discrete values only and thus can be labeled with stars. Star upgrades thus imply reputation jumps, leading to discrete increases in flows and expected performance, although stars do not provide new information. 相似文献
