债权抵押债券运作机理及其在我国的前景分析

自2008年美国次贷危机爆发以来,CDO成为人人谈之色变的毒物。本文在简单介绍CDO运作原理的基础上,着重分析其特性是否能够为我国金融市场的发展带来良好的变化与引导,同时通过分析我国市场现状,对开辟本土CDO市场提出了一些疑问与建议。     

成品油消费税改革的供求效应

消费税改革对于促进经济社会发展具有重要作用。成品油消费税的改革必将通过税负与税负归宿的变化影响成品油的供求,进而影响绿色经济的发展。本文在成品油消费税税负归宿理论分析的基础上,实证检验了成品油消费税改革的供求效应。实证表明:提高成品油消费税的税率,对成品油的供给短期内有较明显的抑制作用,但长期作用不明显;而对成品油的需求也有一定的抑制作用,主要体现在企业消费者的需求有所下降,但对居民汽油消费的抑制作用较弱。然而,若将消费税的征税环节从生产环节调整至消费环节,不仅对消费的影响更为明显,会直接减少成品油的需求量;而且税率上调的政策效果也会事半功倍,优于在生产环节课征的政策效果。     

Corporate Governance and Corporate Financing and Investment during the 2007‐2008 Financial Crisis

We examine the impact of the 2007‐2008 financial crisis on nonfinancial firms’ financing and investment activities and the role of corporate governance in alleviating the adverse consequences of the external capital supply shock. Employing a difference‐in‐differences research design, we find that better governance mitigates the disruption caused by the bank credit supply shock to firms’ financing and investment activities. A variety of robustness tests suggest that our findings are unlikely to be driven by an endogeneity problem. We obtain similar results when we extend the sample period to include the delayed spillover from the banking sector to other capital market sectors.

气候变化对经济金融系统性冲击的物理风险研究

中国作为全球最大的发展中国家,其综合实力伴随着经济、科技的快速发展而不断增强。但我国的极端气候事件趋多趋强,气候风险水平呈上升趋势,影响我国经济社会的发展。金融作为经济运行的核心,在宏观经济中有着举足轻重的作用。为了研究气候变化与经济金融稳定之间的关系,本文对极端气候事件损失体系和区域经济金融稳定性综合体系进行指数合成并构建面板模型探讨气候变化中气温和降水量因素的变动和极端气候事件对区域金融稳定的影响,得出气候变化的物理风险通过极端气候事件对经济发展和金融稳定有负面影响,并根据实证结果提出完善绿色金融市场和优化信息披露制度的政策建议。     

The impact of reporting frequency on the information quality of share price: evidence from Chinese state-owned enterprises

As a major global exchange, the Stock Exchange of Hong Kong (SEHK) only requires semi-annual reporting whereas other major exchanges including the ones in Chinese mainland require quarterly reporting. We argue against the traditional view that higher reporting frequency is necessarily more beneficial. The decision on reporting frequency depends on how the information is being processed by the recipient traders and the results are not obvious. Using a sample of Chinese companies duallisted in both China A share market and SEHK (AH shares) as the experimental group and mainland’s companies listed on SEHK (H shares) only as the control group, we apply the difference-in-difference (DID) method to investigate the impacts of reporting frequency on stock information quality. The results suggest that after China A share market require quarterly financial reporting for all listed companies in 2002, the information asymmetry of the H tranche of AH stocks increases. Different from prior studies, the results suggest a negative association between stock information quality and financial reporting frequency. We argue that the increased information asymmetry in the H tranche is caused by the noise spilled over from the A tranche. We conduct multivariable GARCH tests and find evidence supporting this conjecture.

REAL OPTIONS WITH COMPETITION AND REGIME SWITCHING

In this paper, we examine irreversible investment decisions in duopoly games with a variable economic climate. Integrating timing flexibility, competition, and changes in the economic environment in the form of a cash flow process with regime switching, the problem is formulated as a stopping‐time game under Stackelberg leader‐follower competition, in which both players determine their respective optimal market entry time. By extending the variational inequality approach, we solve for the free boundaries and obtain optimal investment strategies for each player. Despite the lack of regularity in the leader's obstacle and the cash flow regime uncertainty, the regime‐dependent optimal policies for both the leader and the follower are obtained. In addition, we perform comprehensive numerical experiments to demonstrate the properties of solutions and to gain insights into the implications of regime switching.
