本文以金融系统性风险的同步变量构成的中国金融压力指数为被解释变量，以滞后的宏观经济变量、货币信贷变量、资产价格变量和相关经济大国的宏观经济变量为解释变量，运用逐步回归法建立了金融系统性风险最佳预测方程，从而构建起了金融系统性风险预警的合理、实用的指标体系；并用此最佳预测方程对我国2010年金融系统性风险状况进行了预测。预测结果表明，前三季度我国金融系统性风险呈上升态势，且高于2008年的最高值；第四季度开始，金融系统性风险有下降趋势。 his paper treated the Chinese Financial Stress Index which constructed by synchronized variable of the financial systemic risk as the explained variable, and lagged macroeconomic variables, monetary and credit variables, asset price variables and related foreign countries’ macroeconomic variables as explanatory variables. Using stepwise regression, we established the best financial systemic risk forecast equation and built a reasonable and applied financial systemic risk prediction index system. Using the equation we forecasted the financial systemic risk status of China in 2010. The predicted result is that the financial systemic risk rise in the first three quarter, and is higher than the highest value in 2008; the financial systemic risk goes downward in the fourth quarter.

This paper studies idiosyncratic risk of new ventures. An option-based model of a new venture with multistage investments and jumps is developed. Our model ex- plains (1) why new ventures?idiosyncratic volatility eventually decreases as they clear R&D investment stages and become mature ?rms ?the stage-clearing e¤ect; (2) the negative relation between jumps in value and subsequent idiosyncratic volatility ?the jump e¤ect; (3) the dynamics of idiosyncratic volatility under di¤erent schedules of staged venture capital investments; and (4) the e¤ect of di¤erent schedules of staged investments on ?rm valuation with the presence of jumps. Empirically, we develop a generalized Markov-Switching EARCH model to simultaneously capture structural changes in ?rms?idiosyncratic volatility and the relation between jumps and idiosyn- cratic volatility. Using a hand-collected dataset of early-stage biotech ?rms, we ?nd empirical evidence supporting the jump e¤ect and the stage-clearing e¤ect described by our model.

2009年12月，巴塞尔委员会（BIS）面向全球公布了关于增强银行体系稳健性的一揽子政策建议草案征求意见稿。该意见稿由《增强银行体系稳健性（Strengthening the resilience of the banking sector）》和《流动性风险计量、标准和监测的国际框架（International framework for liquidity risk measurement, standards and monitoring）》两份文件共同组成，是对以往国际银行监管制度的进一步完善。但是，征求意见未强调此轮金融危机爆发的重要原因，即：现有制度未能有效维护金融市场竞争，同时，更未能体现以制度破除金融市场垄断的国际趋势。为此，尤有必要从金融竞争制度视角对意见稿进行完善。

ABSTRACT：As an important derivative instrument, CDO is playing a crucial role in the financial crisis. With complicated structure, we have developed many pricing models, which all relay on complicated mathematical model. The paper, firstly, introduces the mainstream pricing model----structural model and reduced form model. Then we introduced the Hybrid Models based on two formal models, by discussing the parameter of pricing i.e. default probability, default free risk and default correlation. In this paper, we give the hybrid model by Monte Carlo simulation based on copula function. Finally, we consider the pricing sensitivity on various parameters. According to the result of simulation, the relationship between the tranches price and pricing parameters is various. For the equity tranche and mezzanine tranche, the price and recovery rate have a positive correlation, while the case is inverse for the senior tranche. We also can conclude that, higher default correlation can lower the price of equity tranche, and have an opposite effect on the senior tranche. The influence on the mezzanine tranche isn’t certain. Furthermore, by comparing two different copula function model, we can get that marginal distribution has different effect on the tranches price.

本文考虑一个面临经营性风险（非系统风险）的企业家，在给定的债务及企业所得税率下，如何通过消费平滑、企业资本投资、破产保护以及金融风险投资，实现消费效用最大化的公司金融问题。本文得到了非风险中性下企业资本价值的半闭式解及相应的最优经营策略和最优破产阀值。对应经典的资本资产定价（CAPM）理论，得到了企业家的期望收益率、贝塔系数、系统风险溢价和非系统风险溢价（idiosyncratic risk premium）。不同于传统观点，非系统风险溢价严格大于零。这些结论和数值计算表明，企业家的风险态度对企业资本价值、最优资本结构，资本投资策略、破产水平、贝塔系数、非系统风险溢价、期望收益率等具有显著的影响。

Policy actions by the Federal Reserve during the recent financial crisis often involve recapitalization of banks. This paper offers a theory of the non-neutrality of money for policy actions taking the form of injecting capital into banks via nominal transfers, in an environment where banking frictions are present in the sense that there exists an agency cost problem between banks and their private-sector creditors. The analysis is conducted within a general equilibrium setting with two-sided financial contracting. We first show that even with perfect nominal flexibility, the recapitalization policy can have real effects on the economy. We then study the design of the optimal long-run recapitalization policy as well as the optimal short-run policy responses to banking riskiness shocks.

In this paper, we derive the corresponding implied VIX formulas under the locally riskneutral valuation relationship proposed by Duan (1995) when various forms of GARCH model are proposed for S&P 500 index. The empirical study shows that the GARCH implied VIX is consistently and significantly lower than the CBOE VIX for all kinds of GARCH model investigated. Moreover, the magnitude of the difference suggests that the GARCH option pricing model is not capable of capturing the variance premium, which indicates the incompleteness of the GARCH option pricing under the locally risk-neutral valuation relationship. The source of this kind of incompleteness is then theoretically analyzed. It is shown that the framework of GARCH option pricing model fails to incorporate the price of volatility risk or variance premium.

This paper mainly finds that there is return predictability across equity-link firms in China’s stock market. By grouping the shareholder firms according to the shocks translated from their equity-link firms, we construct long-short momentum strategy to capture abnormal return of 2.01% per month, which we call “equity-link momentum”. After an array of adjustments based on risky factors and firm characteristics, the excess returns are still significant. However, the significance of equity-link momentum returns are sensitive to various attention proxies, such as firm size, past performance, turn over and mutual funds’ joint holding measurement, which is consistent with the hypothesis of limited attention.

After the first index fund launched in 1999, the index fund market has been growing steadily in China. In this paper, we seek to measure and understand the tracking error of China based index funds. The results show that sample index funds exhibit an acceptable level of tracking error in general. Furthermore, by means of decomposition of tracking error variance we find that risk structure of sample funds keeps consistency with financial theory about indexing. While there is an exception such as Hua An MSCI China A share e.g., whole performance of the better run index funds suggests that indexing is practicable under China conditions.

We study the connection between the stock market and the labor market. When aggregate risk premiums are time-varying, predictive variables for market excess returns should forecast longhorizon growth in the marginal bene?t of hiring and thereby long-horizon aggregate employment growth. Consistent with this logic, we document that high values of the risk premiums forecast low payroll growth and increases in unemployment rate in the short run, but high payroll growth and decreases in unemployment rate in the long run. High values of lagged payroll growth and decreases in lagged unemployment rate also forecast low stock market excess returns.
