开放格局下证券公司价值增值研究

续中国签署WTO协议后,第二轮中美战略与经济对话将促进中国证券业市场进一步开放,高盛在中国的发展反映了中国证券市场的开放历程。通过考察开放格局下中国证券公司和美国证券公司的差距,以及不同规模的中国证券公司之间收入结构异同,认为在目前中国证券公司不具有竞争优势的情况下,中国应学习日本、韩国和台湾地区的谨慎开放政策和与经济实力相辅原则,控制开放速度及培育有利于中国证券业可持续发展的竞争格局。不同规模的中国证券公司必须通过对外部环境和自身优劣势科学分析,找出促进自身价值增值的战略和途径,培育各具特色的核心竞争力。     

Convergence of Real Capital Market Interest Rates—Evidence from Inflation Indexed Bonds

This paper investigates the convergence of long‐term ex ante real interest rates (RIRs) obtained from Canadian, French, UK, and U.S. inflation indexed government bonds. In contrast to previous research, our evidence suggests full convergence in the long run and, hence, capital market integration. For the same sample period, global convergence is rejected for RIRs measured in conventional terms. From these results, we conclude that previous tests of the long‐run real interest rate parity might have suffered from weak measurement of real capital market interest rates.     

Regulatory Uncertainty and Financial Contagion: Evidence from the Hybrid Capital Securities Market

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids.     

融资融券试点对我国股票市场波动性的影响实证研究

融资融券交易正式启动对我国股票市场将产生什么样的波动性影响,是学术界和理论界共同关注的焦点。本文在前人研究基础上,从我国实际情况出发,以标的证券指数——上证50指数与深证成指指数作为影响我国股票市场的代表展开实证,运用GARCH族模型,引入虚拟变量D,其中D用来刻画融资融券推出前后对我国股票市场的影响。通过建模,得出融资融券试点一年多时间以来有利于减小我国股票市场波动性的结论。     

我国证券投资者权益保护问题研究

目前,我国证券市场对证券投资者保护的法规尚不健全,法律的执行力不够;证券市场监管机制也不完善,上市公司特殊的股权结构,以及投资者自我维权意识的不足,使得投资者的权益容易受到侵害。本文认为,要有效保护证券投资者权益,应进一步加大证券市场投资者保护法规建设力度,加强外部行政、司法干预及行业监管,建立行业自律和投资者赔偿机制,从多层面改善证券投资者保护现状。     

基于博弈视角的证券市场监管方式改进研究

监管行为和违规行为是证券市场中的一对矛盾体,两者互相博弈。本文通过建立证券市场中监管行为与违规行为的博弈模型,分别得出纯策略纳什均衡和混合策略纳什均衡。结果表明:均衡点与监管成本、违规行为处罚力度和违规收益等因素有关。最后提出了规范我国证券市场发展的若干政策建议。     

中小证券公司后台业务外包分析

随着证券市场的发展,各中小证券公司后台日益庞大,后台系统投入大幅增长,但业务范围和营销能力并未随之大幅增加,导致后台出现产能过剩,产生大马拉小车和IT黑洞等现象。由于成本原因,目前许多中小证券公司管理层对新系统的投入和团队建设处于彷徨境地。本文提出通过将后台业务外包,来解决中小证券公司后台成本居高不下的问题。     

Inflation Expectations and Risk Premiums in an Arbitrage‐Free Model of Nominal and Real Bond Yields

Differences between yields on comparable‐maturity U.S. Treasury nominal and real debt, the so‐called breakeven inflation (BEI) rates, are widely used indicators of inflation expectations. However, better measures of inflation expectations could be obtained by subtracting inflation risk premiums (IRP) from the BEI rates. We provide such decompositions using an affine arbitrage‐free model of the term structure that captures the pricing of both nominal and real Treasury securities. Our empirical results suggest that long‐term inflation expectations have been well anchored over the past few years, and IRP, although volatile, have been close to zero on average.     

Distribution of occupation times for constant elasticity of variance diffusion and the pricing of α-quantile options

The main results of this paper are the derivation of the distribution functions of occupation times under the constant elasticity of variance process. The distribution functions can then be used to price α-quantile options. We also derive the fixed-floating symmetry relation for α-quantile options when the underlying asset price process follows a geometric Brownian motion.     

证券公司需采取哪些措施才能做到有效合规

法律法规及规章制度的建立健全仅仅是合规管理工作开展的前提和基础,证券公司能否有效合规还必须通过努力,提升执行力。首先,提升证券公司高管对合规管理的全面认识,加强管理层的驱动作用。其次,给予合规管理工作及合规人员的正确定位。再次,加强对各部门的合规管理执行情况的考核力度。最后,不断提升合规管理工作人员的专业素质。
