This paper addresses the estimation of confidence sets for asset correlations used in credit risk portfolio models. Research on the estimation of asset correlations using endogenous probabilities of default estimations has focused on the impact of concentration risk factors, such as firm size and industry. The empirical evidence from Italian small- and medium-size companies show that the assumptions underlying the Basel Committee regulatory capital risk weight function are not substantiated. The regulatory impact is that the capital adequacy is significantly compromised, driving an adverse selection, which favors the worst companies, and transferring the procyclical effects from firms to banks. 相似文献

A contingent claims model is used to study the impact of debt-financing constraints on firm value, optimal capital structure, the timing of investment and other variables, such as credit spreads. The optimal investment trigger follows a U shape as a function of exogenously imposed constraint. Risky, equity-financed R&D growth options increase firm value by increasing the option value on unlevered assets, while their impact on the net benefits of debt is small. 相似文献

中国信贷资产证券化仍处于以零星个案、小规模试点为主的初级阶段。审慎和重在规范的发展路径既推动了信贷资产证券化实践,又尚存诸如与上位法不统一、规则制定权限错配、发行难度和成本增大、一级市场销售不畅、二级市场流动性严重不足等负面效应,制约着信贷资产证券化深入发展。2008年以来,受美国金融危机以及国内宏观调控变化的影响,资产证券化发行环境不利,亟待获得政策层面的持续鼓励和支持。国内商业银行应找准切入点,积极探索业务品种,更好地做好证券化产品的资产储备和发行准备工作。 相似文献

ABSTRACTThis paper explores the extent to which term structure of individual credit default swap (CDS) spreads can be explained by the firm's rating. Using the Nelson–Siegel model, we construct, for each day, CDS curves from a cross-section of CDS spreads for each rating class. We find that individual CDS deviations from the curve tend to diminish over time and CDS spreads converge towards the fitted curves. The likelihood of convergence increases with the absolute size of the deviation. The convergence is especially stable if CDS spreads are lower relative to the rating-based curve. Trading strategies exploiting the convergence generate an average return of 3.7% (5-day holding period) and 9% (20-day holding period). 相似文献

基于次贷危机的启示,本文构建了在不同的金融发展程度下房地产价格波动对商业银行资产影响的理论模型,并在此基础上对中国的现状进行分析,指出当前对中国的影响主要集中于商业银行基于负债业务发放的贷款领域。进一步地,利用向量自回归模型(VAR)及冲击响应函数对中国房地产价格波动对商业银行贷款的影响进行了实证检验。研究表明:金融创新改变了房地产价格波动对商业银行资产的影响模式;中国房价波动对商业银行资产的影响主要集中在源于银行负债发放的贷款领域,但总体影响有限;中国应加快发展银行资产证券化业务,谨慎发展信用衍生产品。 相似文献

本文基于对美国资产证券化发展历程和经验教训的回顾,对中国当前推动信贷资产证券化过程中的监管制度设计进行反思,也对利率市场化加速推进期间资产证券化产品的盈利空间及其可持续性提出质疑。基于此,本文从放松管制、完善法律基础、推动无风险收益率下移、扩大投资者范围和取消贷存比限制等五个方面就如何推动信贷资产证券化持续快速发展提出意见和建议。 相似文献

Recently many kinds of credit derivatives are traded in the market. The default probability implied in the market becomes important to price some credit derivatives. Also it is useful for managing the credit risk because it includes the market information. In this paper we show how to calculate the implied default probability in the default swap market or the defaultable bond market.This paper is developed from author’s master thesis (Matsumoto, 2000), Graduate School of Systems Management, the University of Tsukuba. 相似文献

In this article we expand and improve the Internet company valuation model of Schwartz and Moon (2000) in numerous ways. By using techniques from real options theory and modern capital budgeting, the earlier paper demonstrated that uncertainty about key variables plays a major role in the valuation of high growth Internet companies. Presently, we make the model more realistic by providing for stochastic costs and future financing, and also by including capital expenditures and depreciation in the analysis. Perhaps more importantly, we offer insights into the practical implementation the model. An important challenge to implementing the original model was estimating the various parameters of the model. Here, we improve the procedure by setting the speed of adjustment parameters equal to one another, by tying the implied half‐life of the revenue growth process to analyst forecasts, and by inferring the risk‐adjustment parameter from the observed beta of the company's stock price. We illustrate these extensions in a valuation of the company eBay. 相似文献

We study the effect of the sovereign credit ratings on the economies of seven East Asian countries, applying panel vector autoregression (VAR). We find that rating has less effect than outlook of rating on the credit default swap (CDS) spreads, the stock indexes, and the GDP growth rates. Rating upgrade and positive outlook have stronger effects than rating downgrade and negative outlook, and the effects of positive outlook and rating are greater after the financial crisis. There is evidence of contagion in that the economic variables of a country seem to have been affected by the outlooks of the other countries. 相似文献

由于美国住房抵押贷款证券化产品的暴跌是次贷危机引爆器,因此,人们在研究加强资本监管时,会对证券化的资本计量给予特别关注。本文从理论结合实践的角度,对证券化产品各类市场参与者的相关资本计量问题进行了思考,梳理并归纳了资产证券化发起机构、投资机构和中介机构在各自资本计量过程中需遵循的原则及思路。 相似文献

Exploring the components of credit risk in credit default swaps 总被引:1,自引:0,他引:1
In this paper, we test the influence of various fundamental variables on the pricing of credit default swaps. The theoretical determinants that are important for pricing credit default swaps include the risk-free rate, industry sector, credit rating, and liquidity factors. We suggest a linear regression model containing these different variables, especially focusing on liquidity factors. Unlike bond spreads which have been shown to be inversely related to liquidity (i.e., the greater the liquidity, the lower the spread), there is no a priori reason that the credit default swap spread should exhibit the same relationship. This is due to the economic characteristics of a credit default swap compared to a bond. Our empirical result shows that all the fundamental variables investigated have a significant effect on the credit default swap spread. Moreover, our findings suggest that credit default swaps that trade with greater liquidity have a wider credit default swap spread. 相似文献

出于融资的需求,资产证券化登上历史舞台。可用于证券化的资产包括信贷资产、不动产和知识产权等。资产证券化注重对资产信用价值的利用,促进了资产价值的流动,实现了资产价值最大化。在资产支持证券的流转过程中,传统法律规则多处被突破。资产证券化体现了现代商法的特征。资产证券化在我国起步较晚,我国应加快资产证券化的立法进程。次贷危机虽使资产证券化受到质疑,但如果选择优等资产予以证券化,就可以最大限度地避免证券化中的风险。 相似文献
