跨境上市与证券市场流动性之争研究述评

跨境上市以及跨市场证券交易的迅猛发展,对全球证券市场产生了较大的影响。本文对跨境上市对市场流动性影响的国内外研究进行了综述。综合国外研究发现,企业跨境上市对企业母国证券市场的流动性冲击主要有正向效应、负向效应和双赢局面三种可能,具体取决于该国市场的实际情况。影响流动性冲击方向的主要因素包括:母国市场散户投资者数量,市场透明度和市场间信息关联度,时区差异、佣金费率和母国市场发展程度,政府资金管制以及市场间证券报酬率的相关性五个方面。国内针对跨境上市的相关研究也在不断开展,但是针对跨境上市对我国证券市场可能造成的冲击和影响的研究还比较匮乏,有待加强。     

The costs of foreign single listing

A significant number of firms conduct their initial public offerings in a foreign market without a domestic listing; this is known as a foreign single listing. The existing literature has mainly focused on examining cross-listings – where firms are listed in both the domestic market and one or more foreign markets – with little attention to foreign single listings. This study examines the costs of foreign single listings. Using a sample of Chinese firms, we show that – on average – the stocks of foreign single-listed firms are undervalued by around 20–30% relative to cross-listed firms. The results are robust in both panel regressions and in a natural experiment analysis. Our findings have strong implications for firms which may consider listing overseas.     

International Financial Liberalization and Economic Growth

This paper pulls together existing theory and evidence to assess whether international financial liberalization, by improving the functioning of domestic financial markets and banks, accelerates economic growth. The analysis suggests that the answer is "yes." First, liberalizing restrictions on international portfolio flows tends to enhance stock market liquidity. n turn, enhanced stock market liquidity accelerates economic growth primarily by boosting productivity growth. Second, allowing greater foreign bank presence tends to enhance the efficiency of the domestic banking system. In turn, better-developed banks spur economic growth primarily by accelerating productivity growth. Thus, international financial integration can promote economic development by encouraging improvements in the domestic financial system.     

Government Bonds in Domestic and Foreign Currency: the Role of Institutional and Macroeconomic Factors*

In contrast to some recent research, this paper finds that institutional and macroeconomic factors are related to the depth and currency composition of government bond markets. Using panel data for developed and emerging economies, we find several factors to be systematically associated with bond markets. Aside from economic size (already shown to affect the currency composition), this paper shows that investor bases matter. Economies with deeper domestic financial systems (measured by bank deposits and stock market capitalization) have larger domestic currency bond markets and issue less foreign currency debt, whereas foreign investor demand is positively related to the size and share of foreign currency bonds. Moreover, less flexible exchange rate regimes are associated with more foreign currency issuance. Other relevant variables include inflation, fiscal burden, legal origin, and capital account openness.     

COMMON STOCHASTIC TRENDS AMONG THE CYPRUS STOCK EXCHANGE AND THE ASE,LSE AND NYSE

Common stochastic trends among major international stock price indices have been an intensively analysed issue mainly as a result of the 1987 stock market crash and the need for policy coordination in financial markets. This paper investigates the existence of common stochastic trends among an emerging equity market, the Cyprus Stock Exchange, and three mature equity markets, namely the Athens Stock Exchange (ASE), the London Stock Exchange (LSE) and the New York Stock Exchange (NYSE).     

How to maximize golden opinions

In this article, we aim to model the level and structure of the dependence between the world's leading stock markets and those of the emerging market groups?–?Europe, Latin America and Far East. To this end we use a mixture model of Gaussian, Gumbel and Gumbel survival copulas. Our results indicate that none of the pairs of stock markets exhibit a right-tail dependence structure. All valid models exhibit a mixture of Gaussian and left-tail dependence structure. Our findings imply that Gaussian dependence structure is dominant in most of the models. The emerging equity markets in the European region exhibit the most significant dependence structure with the world leaders. Furthermore, most of the emerging equity markets have a significant dependence structure with the US stock market. We further compare our findings with the results of the conventional correlation coefficients and conclude the importance of using copula models in analysing the portfolio diversification opportunities. Our findings overall indicate two important remarks: First, the copula models reveal better indicators for global investors to establish a diversified portfolio; Second, international equity markets exhibit significant dependence, which leaves a smaller opportunity to benefit from international portfolio diversification.     

Return predictability in emerging equity market sectors

This article investigates the predictive power of technical trading rules in the emerging equity market sector portfolios and finds that trading strategies based on technical indicators significantly outperform the buy-and-hold benchmark. Combination of data snooping bias, data measurement errors in the form of non-synchronicity bias and fluctuations in currency exchange rates is unable to explain the observed outperformance. The introduction of transaction costs tempers the results but technical analysis still possesses significant predictive power for a number of sectors. The performance of technical analysis in the emerging equity market sectors does not conform to historical trends observed in the developed equity markets as well as in the emerging equity markets when broadly diversified portfolios are considered, where predictive power of technical trading rules has been shown to decline over time.     

Will Sub-Prime be a Twin Crisis for the United States?

We identify incentives generated by the Bretton Woods II system that may have contributed to the sub-prime liquidity crisis now working its way through the international monetary system. We then evaluate the persistent conjecture that the liquidity crisis is or will become a balance of payments crisis for the United States. Given that it happens, the additional costs associated with a sudden stop of net capital flows to the United States could be quite substantial. But we observe that emerging market governments have continued to acquire US assets even as yields have fallen, and the incentives for continuing to do so remain strong. Moreover, the Bretton Woods II system, which has clearly been the most resilient of the forces driving current markets, continues to generate low real interest rates in industrial countries and growth in emerging markets that will help limit the damage from the liquidity crisis.     

The Impact of a Disorderly Resolution of Global Imbalances on Global Wealth

Partly reflecting structural advantages such as liquidity and strong investor protection, foreigners have built up extremely large positions in US (as well as other dollar‐denominated) financial assets. This paper describes the impact on global wealth of an unanticipated shock to US financial markets. For every 10 per cent decline in the dollar, US equity markets, and US bond markets, total wealth losses to foreigners could amount to about 5 percentage points of foreign GDP. Four stylized facts emerge: (i) foreign countries, particularly emerging markets, are more exposed to US bonds than to US equities; (ii) over time US exposure has increased for most countries; (iii) on average, US asset holdings of developed countries and emerging markets (scaled by GDP) are very similar; and (iv) based on their reserves position alone, wealth losses of emerging market governments could on average amount to about 2¾ percentage points of their GDP.     

Asset Markets and Endogenous Liquidity

In financial markets characterized by imperfect depth, speculative trading will have transitory effects on the market price as market makers must be compensated for the risk of holding the asset. The number of people providing liquidity to a market will generally be endogenously determined by the quantity of liquidity demanded. This paper looks for evidence of endogenous liquidity provision in several international stock and bond markets. Evidence shows strong support for these speculative dynamics in the stock markets. The evidence for these dynamics is less striking with fixed‐income prices, consistent with the less speculative nature of these markets.     

Financial cycles in asset markets and regions

This paper provides a comprehensive analysis of financial cycles in asset markets and regions. Using a large sample of 38 advanced and emerging economies to enable a comparative assessment, the analysis conforms with the prevailing literature pertaining to the characterization of financial cycles in advanced economies, but finds that equity market cycles in emerging market economies (EMEs) in Asia, Latin America, and Eastern Europe may be a more useful gauge of the financial cycle compared to cycles in credit and property markets. Similar to more advanced economies, it is found that financial and business cycles in emerging economies are synchronized, albeit partially and with some cross-country heterogeneity. This underscores the importance for policy makers to be vigilant of interlinkages between real and financial sectors, pointing toward a need for carefully designed macroprudential policies. Finally, it is found that financial cycles in emerging markets remain vulnerable to global risk aversion in financial markets and spillovers from the US, thereby reinforcing the importance of continuing to strengthen domestic macroeconomic fundamentals, and develop further local financial sectors through targeted structural reforms.     

How pervasive is the effect of culture on stock market linkages? Evidence across regions and economic cycles

We conduct a comprehensive study on the effect of culture on stock market linkages. With data on 25 national stock markets, a quantile regression model is used to estimate the determinants of market linkages using culture variable/s such as language, religion and Hofstede’s cultural dimensions while controlling for distance, economic and legal variables. Further, we test whether these effects hold across regions and if changes are detected during periods of market crisis. We also test if market liquidity, an indicator of market efficiency, diminishes the impact of culture on market linkages. The main conclusion is that culture preferences shape investor choices, which affects integration between stock markets. The equity markets with similar cultural traits tend to increase market linkages; however, we observe differences across regions. Furthermore, liquidity and economic uncertainty fail to have an impact on the significance of culture variable/s as determinants of market linkages.     

The Impact of U.S. Individual and Institutional Investor Sentiment on Foreign Stock Markets

This study examines the degree to which U.S. individual and institutional investor sentiments are propagated abroad. Previous studies construe investor sentiments as fully irrational; we find contrary evidence that individual and institutional investor sentiments are driven by both rational and irrational factors, with distinct effects on domestic and international stock market returns. The generalized impulse response functions from VAR model estimations show that U.S. institutional investor sentiments have varying degrees of impact on the equity markets of the U.K., Mexico, and Brazil, and no effect on Chile. Specifically, the individual investor sentiment effect is statistically significant only for the U.K market. Not surprisingly, the two classes of investor sentiments have a strong significant effect on the U.S. stock market returns. The response of the U.S. to individual investor sentiments is relatively more erratic, while the response to institutional investor sentiments is smoother. This difference in pattern becomes more visible when we consider the response of the foreign stock markets. We find significant effects of rational sentiments of institutional investors on the U.S., the U.K., Mexico, and Brazil. However, there is an insignificant effect of the irrational sentiments on the same set of countries. A direct implication of our empirical evidence is that it is important for international asset pricing models to consider the role of rational sentiments of institutional and individual investors on developed and emerging markets.     

Risk Appetite,Home Bias and the Unstable Demand for Emerging Market Assets

Home bias arises when the actual portfolio of an investor consists of a smaller proportion of foreign assets than that predicted by standard portfolio theory for the observed set of risks and returns on available assets. The existence and persistence of home bias undermines the theoretical case for the efficiency of international capital markets. In this paper we use data on UK pension fund portfolios to measure home bias, and find that this is doubly acute in the case of emerging market equity—a bias against overseas assets as a whole being further magnified by a bias against emerging markets within the foreign equity class as a whole. Moreover, contrary to the conventional assumption that risk aversion is both relatively low and stable over time (canonised in neoclassical theory by the derivation of constant relative risk aversion from the utility function itself) our finding that home bias fluctuates over time suggests that risk aversion is in fact time‐variant and path‐dependent. We sketch an alternative Keynesian approach in conclusion.     

Liquidity in Asian markets: Intensity of Regional and global linkages

This study investigates cross-market linkages and the intensity of liquidity spillovers across nine Asian markets and five developed markets during 2006 to 2016. Further, the study examines the contagion caused by recent global financial crisis and its impact on the market liquidity. The direction and intensity of spillovers has been measured using forecast error variance decomposition method as suggested by Diebold and Yilmaz (2012). Among the developed markets, the United States, Germany and the United Kingdom significantly affect liquidity changes in Asian countries like India, China, Singapore and Japan. The results revels that on average, each Asian market receives 7% spillover from the global markets and 16% from regional markets. During the financial crisis, the average regional spillover increased to 20% and the global spillover increased to 11%. Thus, in Asia, the regional spillover is higher than the global spillover. Our results support the demand side hypothesis and suggest that it is the trade and portfolio investments that drive the liquidity spillovers. Our findings have potential implications for international investors, policy makers and market regulators.     

全球市场一体化——全球情景下Fama-French三因子模型检验

通过在全球情景下检验Fama-French三因子模型,分析了新兴市场与发达国家的市场一体化水平。沿用Griffin的研究方法,利用涵盖35个国家、时间跨度超过30年的股票市场数据,分析并比较了基于世界、国际和本国三种视角构建的Fama-French三因子模型在解释股票收益差异上的适用性。结果如下:不同国家或地区在市值因子(SMB)、账面市值比因子(HML)和市场资产组合(MRF)上的相关性不足以说明市场一体化水平;三种模型对发达国家和发展中国家的股票市场都具有解释力;与Griffin的研究结果一致,Fama-French本国版模型最能有效解释股票收益率差异,因此没有必要将模型放在全球情景框架下加以考虑。     

Market efficiency and international diversification: Evidence from India

This study evaluates one of the most important emerging markets, India (Bombay Stock Exchange and Indian National Exchange), for its efficiency and for its potential to offer diversification benefits to international investors. Market-wide tests include; 1) contemporaneous relationship, 2) Granger type causality and 3) day-of-the-week effect. Tests on individual Indian stocks include: 1) panel estimation of Granger causality, 2) stock-by-stock estimation of Granger causality and 3) runs test. In sum, Indian markets are well integrated with the international equity markets, a characteristic that lowers the international diversification benefits. While day-of-the-week effect is an international spillover, it may be possible to predict individual Indian stocks' returns through causality with international equity markets and through momentum trading techniques.     

当前中国资本市场面临的三大问题

透明度是全球资本市场面临的共同问题。如果我们不能有效地解决透明度问题,不能解决上市公司和中介机构如实地向社会披露信息的问题,那么资本市场就没有发展前途。资金多元化问题是中国资本市场发展面临的重要问题。中国资本市场如果要成为现代金融体系的基础,我们就必须推动资本市场资金渠道的多元化。股权分裂是中国资本市场目前面临的根本性问题。中国资本市场规范和发展的重点,是如何建立一个具有完整流动性的市场,而不是流动性分裂的市场。中国资本市场存在的种种问题,大多源自于股权分裂所决定的制度缺陷。     

Financial Returnees as New Agents in East Asia: The Case of Korean Private Equity Funds

Although the standing of Anglo-American capitalism has been badly damaged by the global economic crisis, the return of the state in emerging markets is by no means assured. Over the past decade, financial processes originating in Anglo-American markets, such as derivatives, hedge funds and mergers and acquisitions (M&A), have made quiet headway in emerging markets. One of the transmission channels is financial returnees, defined as elites returning to domestic finance from either global finance abroad or from foreign financial institutions in their home countries. Many financial returnees pursue business agendas that parallel the Anglo-American model, while portraying themselves as local for domestic constituencies. These actions are now especially visible in the rise of private equity funds in emerging markets. This article defines the concept of a financial returnee and charts the impact of these individuals in importing the Anglo-American private equity model to Asia with Korea as the primary case study. Once foreign-controlled, the private equity industry in Korea is now domestically-run and financial returnees have been integral in this sector's short but important history.     

International spillovers from US forward guidance to equity markets

We quantify the international spillovers of explicit Federal Open Market Committee (FOMC) policy rate guidance used as an unconventional monetary policy tool at the zero lower bound of the policy rate on international equity markets, considering equity indices of both advanced and emerging economies. We find that stimulatory explicit FOMC policy rate guidance announcements at the zero lower bound led to higher equity prices in a number of advanced and emerging economies. Moreover, we find that equity indices of economies with lower sovereign ratings rose by more, consistent with the risk-taking channel of monetary policy.
