引入优先股是证券市场的一项重要的制度安排

证券市场的管理和创新始终是证券监管部门的一项重要职能。中国证券市场由于其诞生背景的特殊性,使其具有天然的缺陷,证券品种单一即是其一。引入优先股是证券市场的一项重要的制度安排。本文在对优先股的特点和意义论述的基础上,结合国内外优先股的实践,对我国证券市场引入优先股提出了有关建议。     

企业资产证券化业务的特殊价值与可行性研究

企业资产证券化是一种以专项计划为载体的企业未来收益权或既有债权证券化的融资方式,是融资方式变革的一个方向。在探讨企业资产证券化性质的基础上,分别从实体经济发展、资本市场发展、企业发展及证券公司自身发展等角度,分析了证券公司开展企业资产证券化业务的特殊价值;又依据基础环境、自身优势、市场前景等因素,论证了证券公司开展企业资产证券化业务的可行性。

Foreign Entry into Underwriting Services: Evidence from Japan's “Big Bang” Deregulation

We examined the effect of foreign entry into bond market underwriting activity using issue‐level data from the Japanese “Samurai” and euro–yen bond markets. We found that the fees charged by Japanese underwriters were higher on average than those of foreign underwriters, but the difference could be explained by conditioning on issue characteristics. Our results also suggest that bond issuers sorted properly across underwriters, as switching across underwriter nationalities would be expected to result in higher fees. However, the savings enjoyed by firms issuing with foreign underwriters were modest and statistically insignificant, while those of firms issuing with Japanese underwriters were substantial and statistically significant. This result suggests that Japanese underwriters priced their services aggressively over the sample period, perhaps in an effort to retain or gain market share. This conjecture is supported by a matching exercise that examined the liberalization of foreign underwriter access to the Samurai bond market, using euro–yen bond issues as a control. Foreign entry led to a statistically and economically significant decrease of 16 basis points on average in underwriting fees in the Samurai bond market. Overall, our results suggest that the international market for Japanese bond underwriting services was partially segmented by nationality as issuers appear to have preferred habitats, but that liberalization increased overall market competition.     

实施转融通制度提高了我国证券市场质量吗？——运用双重差分模型对沪深股市的实证分析

以50种纳入转融通标的证券的股票构造处理组,以50种纳入融资融券标的证券但未纳入转融通标的证券的股票构造控制组,利用转融通制度实施前后各10个交易月份的数据,采用双重差分模型研究转融通制度的实施对证券市场流动性、波动性、有效性等市场质量的净影响,得到的可靠结论是：转融通制度在一定程度上提高了证券市场的流动性,显著抑制了证券市场的波动性,显著提高了证券市场的有效性,总体上改善了证券市场质量。监管者应进一步拓宽转融通标的证券的范围,增加转融通标的证券的数量,并对证券进入转融通标的证券之前和之后进行区别对待;交易者在确定交易策略时也应做出正确选择。     

A transform approach to compute prices and Greeks of barrier options driven by a class of Lévy processes

In this paper we propose a transform method to compute the prices and Greeks of barrier options driven by a class of Lévy processes. We derive analytical expressions for the Laplace transforms in time of the prices and sensitivities of single barrier options in an exponential Lévy model with hyper-exponential jumps. Inversion of these single Laplace transforms yields rapid, accurate results. These results are employed to construct an approximation of the prices and sensitivities of barrier options in exponential generalized hyper-exponential Lévy models. The latter class includes many of the Lévy models employed in quantitative finance such as the variance gamma (VG), KoBoL, generalized hyperbolic, and the normal inverse Gaussian (NIG) models. Convergence of the approximating prices and sensitivities is proved. To provide a numerical illustration, this transform approach is compared with Monte Carlo simulation in cases where the driving process is a VG and a NIG Lévy process. Parameters are calibrated to Stoxx50E call options.

Currency total return swaps: valuation and risk factor analysis

Abstract

Currency total return swaps (CTRS) are hybrid derivative instruments that allow us to simultaneously hedge against credit and currency risks. We develop a structural credit risk model to evaluate CTRS premia. An empirical test on a sample of 23,005 price observations from 59 underlying issuers yields an average percentage error of around 10%. This indicates that, beyond interest rate risk, firm-specific factors are major drivers of the variations in the valuation of these instruments. Regression analysis of residuals shows that exchange rate determinants account for up to 40% of model pricing errors, indicating that a currency risk premium affects the CTRS price significantly but only marginally, which confirms the prevalence of credit risk in the pricing of CTRS.     

Emerging Securities Exchanges in Africa

ABSTRACT

African securities markets have not received the academic attention of those in Latin America and Southeast Asia. Historically, capital markets have not played a significant role in financing the development of the African economy. Today, however, African governments are focusing on the importance of moving toward more market-oriented economies and developing the financial market infrastructure to mobilize funds from both the private and public sectors. This paper describes the institutional characteristics of a newly revitalized stock exchange in Nairobi, Kenya. The study concludes that historical and cultural factors play a significant role in the characteristics of the Nairobi Stock Exchange.     

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。
