证券市场间溢出效应的研究综述

在全球资本市场一体化的背景下,不同证券市场间的相关性日益突出。当一个市场受到风险冲击而发生价格变动时,其他市场也可能跟随发生变动,金融风险在市场间的传递是指冲击的跨市场的溢出效应。因此,研究证券市场之间的溢出效应十分必要。本文通过研读大量文献,综述了国内外研究溢出效应的各种方法以及此领域的发展动态。     

中国证券市场监管困境的原因分析

中国证券市场上诸多混乱现象的出现使证券市场的健康发展备受困扰,证券市场监管陷入困境之中.证券市场监管陷入这些困境的直接原因在于政府监管承载过重,范围过宽,导致力不从心;法律监管执法不力,推脱责任,导致威慑失效;自律监管力量微薄,碌碌无为,形同虚设;社会监管不遗余力,但是茫然无助,效果有限.证券市场监管陷入困境的最根本原因是证券市场的制度性扭曲.     

Integration between the London and New York Stock Exchanges, 1825–1925

In this article the integration between the London and New York Stock Exchanges is analysed during the era when they were still developing as asset markets. The domestic securities on both exchanges showed little sustained integration, even when controlling for the different characteristics of stocks, which implies that the pricing of securities in the US and UK was still being driven by local factors. These results place a limit on the view that the pre‐First World War period was the first era of globalization in terms of capital markets. However, there was considerable integration between New York and those listings on London that operated internationally. This suggests that the listing of foreign securities may be one of the primary mechanisms driving asset market integration.     

Information asymmetry,market segmentation,and cross-listing: Implications for event study methodology

This paper connects three subjects related to international financial markets – (i) information asymmetry, (ii) market segmentation, and (iii) cross-listings – and highlights their implication for event study methodology. When firms list equities on more than one exchange, and the exchanges are characterized by different information sets, a problem arises as to which exchange(s) to include in the event study sample. If market segmentation impedes the arbitrage of these multiple responses, then the use of a single listing (for a firm that is cross-listed) can yield abnormal return estimates that are biased. In such circumstances, using returns from all the markets in which a firm's securities are listed not only increases the sample size (often an important consideration when undertaking event studies in emerging markets), but also enables full-information abnormal return estimates to be obtained. What is required is a method that extracts the independent information from each listing while counting the common information only once. In this paper, we develop an estimation procedure that achieves these twin objectives. We then apply our approach to an event study of Chinese overseas mergers and acquisitions, and compare results from alternative samples and estimators. We demonstrate that including return data from cross-listings of the same firm can result in substantially different conclusions.     

Prospects and Challenges for Developing Securities Markets in Ethiopia: An Analytical Review

This paper is an analytical review of the prospects and challenges of developing securities markets in Ethiopia. With the fall of communism and the emergence of capitalism, many countries around the world are moving toward market‐oriented economies and securities markets are springing up on all continents around the globe. Securities markets have come to symbolize to many the essence of capitalistic economic relations. When studying the economies of developing countries, the first thing that becomes apparent is the existence of immense and, to a considerable extent, unemployed human resources as well as an acute shortage of capital. Shortage of capital is a major constraint in the realization of economic development. Recognizing the role that securities markets play in mobilizing capital, more than a dozen African countries have established stock markets. Ethiopia is not one of them. There is little current research which focuses on Africa's securities markets. This study helps to contribute to that effort by focusing on Ethiopia, the second largest country in sub‐Saharan Africa plagued with major economic problems. The paper concludes by recommending the establishment of a stock market and providing suggestions on how to do it.     

The Mortgage and Financial Crises: The Role of Credit Risk Management and Corporate Governance

This paper discusses the role of risk management and corporate governance as causal factors in the onset of the financial crisis. The boom and bust in the housing market precipitated serious strains in financial markets. These strains resulted in the onset of the financial crisis in August 2007 with the collapse of the asset-backed commercial paper market. This collapse occurred because the solvency of a number of large financial firms was threatened by huge losses in complex structured financial securities. Why did these firms have such high concentrations in mortgage-related securities? Given the information available to firms at the time, these high concentrations in mortgage-related securities violated basic principles of modern risk management. We argue that this failure to apply well-understood risk management principles was a result of principal-agent problems internal to the firms and to breakdowns of corporate governance systems designed to overcome these principal-agent problems.

证券交易税调整效应的实证分析

本文针对证券交易税的影响,利用最新的数据进行了实证检验。研究结果表明,证券交易税的调整在短期内会对股票价格和市场波动性有明显影响,而在长期影响不明显。对于中国这样的新兴股票市场,调整证券交易税税率对股市的影响是十分有限的。     

中国证券市场监管的最优策略——一个博弈视角的结论

文章从博弈论的视角,分析了中国证券市场监管的效率。根据证券市场本身的层次,文章构建了一级发行市场中的寻租合谋监管博弈模型和二级交易市场中的混合策略监管博弈模型。根据这些模型分析的结果,可以得出如下的结论：在给定目前中国证券市场监管博弈规则的条件下,监管者和被监管者的最优策略反而导致中国证券市场的低效率;中国证券市场效率的提高,关键在于对目前监管博弈规则的改进。

中国证券监管治理的国际经验借鉴与评估体系重构

通过借鉴证券监管治理评估的国际经验并加入独立设计的指标,构建中国证券监管治理评估指标体系并作出评估。研究结果表明,中国证券监管治理评估指数为68.48。考虑到中国证券市场所处的发展阶段,这个成绩反映了真实情形,说明中国证券监管虽然已基本具备良好监管治理的形式,但也存在不足之处,需要从独立性、责任性、透明度和监管操守四个方面加强监管治理。     

Explaining Foreign Holdings of Asia's Debt Securities: The Feldstein–Horioka Paradox Revisited*

In this paper, we find that home bias is still present in all economies and regions, especially in the case of short‐term debt securities, but that there are substantial variations among economies and regions in the strength of home bias, with the eurozone economies, the USA and developing Asia showing relatively weak home bias and advanced Asia, especially Japan, showing relatively strong home bias. We then examine trends over time in foreign holdings of debt securities and find that capital has been flowing from the USA and the eurozone economies to both advanced Asia (especially Japan) and developing Asia, and that foreign holdings of debt securities have been increasing in advanced as well as developing Asia but for different reasons. The main reason in the case of advanced Asia (especially Japan) appears to be higher risk‐adjusted returns, whereas the main reason in the case of developing Asia appears to be the growth of debt securities markets combined with relatively weak home bias and (in the case of short‐term securities) lower exchange rate volatility. Finally, we find that since the global financial crisis, foreign holdings of debt securities have declined (i.e. that home bias has strengthened) in all economies and regions except developing Asia, where they have increased (except for a temporary decline in 2008) but where their share is still much lower than the optimal share warranted by the capital asset pricing market model.     

Economic Effect of Zoning Regulations on Korea's Small and Medium‐Sized Retailers*

In this paper, we investigated the economic effects of zoning regulations on the retail industry in Korea. We estimated the changes in the number of sales for retail stores using a panel regression analysis for stores in traditional markets. This analysis was conducted to examine the benefit of zoning regulations on retail stores. Our results show that the zoning regulations (called Traditional Commercial Activity Protection Zones) have contributed to an improvement in the actual business performance of small independent retailers. We found that the amount of sales for each store clearly increased on average in the areas designated as Traditional Commercial Activity Protection Zones where there was no market entry of mega supermarket chains (called SSM in Korea). We also present evidence that the effects of this policy differ geographically: the effects were stronger for small and medium cities than for large metropolitan cities. These results suggest that zoning regulations enacted by the government to protect traditional markets and small retailers should also consider regional differences when assessing policy effectiveness.

深圳与上海金融机构的竞争力分析

通过比较,上海的核心优势是金融市场的容量,而深圳的核心优势是拥有有竞争力、本土成长起来的一批金融机构(包括银行、保险、证券、基金)。还发现:良好的股权结构和企业领袖魅力对深圳的银行和保险业影响很大,而证券业和基金业的业绩更多取决于管理层的风格。以后深圳应携手香港,在保持机构竞争力的同时,扩大金融市场的容量和辐射影响力。     

我国创业板上市公司治理问题研究

由于我国证券市场创业板上市公司股权结构具有控股股东持股比例相对较低的特点,这将产生不同于主板上市公司的剥夺型公司治理问题。要解决这一问题,就必需完善保护中小股东的有关法规,加强执法力度,建立声誉约束机制,并加大对失信行为的处罚力度。
