This paper investigates the impact of rating agencies in a market with asymmetric information. In particular, the role of credit rating agencies as an intermediary between investors and bond issuers is discussed. We model this setting in a dynamic framework in which both rating agencies and bond issuers are of heterogeneous quality. Rating agencies can apply costly research technology to reveal the fundamental nature of bond issuers and engage in rating smoothing. We show that rating smoothing can compensate for low research quality, even though it is accompanied by a quality deterioration in the rating market and market clustering. Moreover, low-quality bond issuers have a general tendency to match with low-quality rating agencies. If investors place a strong emphasis on the reputation of rating agencies, rating markets also tend to be strongly clustered. 相似文献

The bureaucratic tendencies to organize work in Higher Education Institutions (HEIs) of which facilitates personnel control and the mechanical ways to measure educational content are the ones that shatter education in pieces, under the hierarchy criterion, also shattering the professor's labor. This organizational method results in an incompetent education, leaving very negative consequences for teaching development. We address this problem by using systemic modeling and Structural Equations Systems (SEM) to confirm hypotheses from scientific observation. It was proven that there was a negative impact of mechanistic management which affected teacher's development. This was proven in context in two HEIs located in Villahermosa (Tabasco, Mexico). 相似文献

ABSTRACTUsing a cross-regional analysis of China, this article shows that the China model view is factually false and the universal model view is factually true. It is the marketization and development of non-state sectors, rather than the strong power of government and the state sector, that have driven the Chinese economy to grow fast and to be increasingly innovative. If China wants to sustain its economic performance, it must stay on the way to continuing marketization. Otherwise, China will fall into stagnation. 相似文献

We conduct an empirical analysis of the term structure in the volatility risk premium in the fixed income market by constructing long-short combinations of two at-the-money straddles for the four major swaption markets (USD, JPY, EUR and GBP). Our findings are consistent with a concave, upward-sloping maturity structure for all markets, with the largest negative premium for the shortest term maturity. The fact that both delta–vega and delta–gamma neutral straddle combinations earn positive returns that seem uncorrelated suggests that the term structure is affected by both jump risk and volatility risk. The results seem robust for macroeconomic announcements and the specific model choice to estimate the risk exposures for hedging. 相似文献

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case. 相似文献

成本计量模式与企业成本控制机制研究 总被引:3,自引:0,他引:3
成本计量模式存在着制造环节、价值链与商业模式三个视角的划分,它们反映了不同成本效益对称情形,三者间具有层次演进性。从成本与利润的关系看,企业内部就是成本计量,利润则是市场角度的成本补偿计量,企业机制就可以视为在有意义的领域做出独特或某种与众不同的贡献而进行的成本流程安排。企业健康成本结构应该是一个开放的以接纳先进价值观的信息综合体。企业要获得可持续竞争力就必须树立科学的成本控制观念。 相似文献

Since health tourism is one of the most popular and most dynamically developing products of modern tourism, this paper aims at studying the characteristic features of health tourism destinations from a regional and spatial perspective. Accordingly, the authors would like to introduce a new approach of spatial and product analysis of tourism where the market and spatial relations and relevance of health tourism were analysed through the example of Hungary. Although the classic medical tourism centres were established on natural medical water basis, by today, due to product diversification, continuous innovation and the involvement of medical services into health tourism, the geographical embeddedness seems to disappear, thus basically restructuring the market. The methodological novelty of the research is that exceeding the classic supply–demand algorithm, we compiled a complex viewpoint system adequate to the specialities of the given product characteristics. In our study, the authors intend to survey the special characteristics of health tourism focusing on medical destinations through Hungarian examples since the country's leading position in the global market is well recognized, including medical services.
