Who Plays the Key Role among Shanghai, Shenzhen and Hong Kong Stock Markets？

In this paper we examine the daily frequency stock market indices of Shanghai, Shenzhen and Hong Kong from January 2000 to June 2012, and use the Morlet wavelet coherence model to determine who is playing the most important role in the financial markets of China. We find that there are significant comovements between these stock markets in the medium and long run. This provides investors with opportunities to increase their capital gains. The Hong Kong stock market plays a leading role in the long run, but its leader position is threatened by fast‐growing Chinese mainland stock markets, especially the Shanghai Stock Exchange. Based on our analysis, the following suggestions apply to the Chinese stock markets: establish and improve international and regional finance centers in Chinese mainland; encourage more qualified institutional investors; reposition the market relations among Hong Kong, Shanghai and Shenzhen; and increase deregulation and internationalization to speed up the integration of financial resources.     

The co-movement of stock markets in East Asia: Did the 1997–1998 Asian financial crisis really strengthen stock market integration?

This paper examines the integration and causality of interdependencies among seven major East Asian stock exchanges before, during, and after the 1997–1998 Asian financial crisis. For this purpose, we use daily stock market data from July 1, 1992 to June 30, 2003 in local currency as well as US dollar terms. The data reveal that the relationships among East Asian stock markets are time varying. While stock market interactions are limited before the Asian financial crisis, we find that Hong Kong and Singapore respond significantly to shocks in most other East Asian markets, including Shanghai and Shenzhen, during this crisis. After the crisis, shocks in Hong Kong and Singapore largely affect other East Asian stock markets, except for those in Mainland China. Finally, considering the role of the USA shows that it strongly influences stock returns in East Asia – except for Mainland China – in all periods, while the reverse does not hold true.     

Efficiency,Cointegration and Contagion in Equity Markets: Evidence from China,Japan and South Korea*

This paper empirically examines whether three East Asian stock markets, namely, those of China, Japan and South Korea, are individually and/or jointly efficient, and whether contagion exists between the cointegrated markets. While individual market efficiency is examined through testing for the random walk hypothesis, joint market efficiency is examined through testing for cointegration and contagion. The present study finds that the hypothesis of individual market efficiency is strongly rejected for the Chinese stock market, but not for the Japanese and the South Korean stock markets. However, when testing for cointegration, market efficiency is strongly rejected for all these markets. We take a simple case of contagion and find that although there is a long‐term relationship among the three markets, the contagion hypothesis cannot be rejected only between Japanese and South Korean stock markets, indicating short‐run portfolio diversification benefits from these two markets.     

Stock prices and the efficient market hypothesis: Evidence from a panel stationary test with structural breaks

This paper investigates whether the efficient market hypothesis holds in stock markets under different economic development levels over the period January 1999 to May 2007. We employ a state-of-the-art panel data stationarity test which incorporates multiple structural breaks. Evidence indicates that when accommodating general forms of cross-sectional dependence as well as controlling for finite-sample bias, the real stock price series appear to be stationary in 32 developed and 26 developing countries, respectively, which is in sharp contrast to the findings in the existing literature. Thus, real stock price indices are stationary processes that are inconsistent with the efficient market hypothesis. This shows the presence of profitable arbitrage opportunities among stock markets. According to these estimated structural breakpoints, we are also able to discover the reason for why there has been a huge impact from past stock prices.     

Equity,Bonds, Institutional Debt and Economic Growth: Evidence from South Africa

We examine the finance‐growth nexus in South Africa accounting for the role of bond markets, stock markets, and bank and non‐bank financial intermediaries using a vector autoregressive technique. Extant empirical literature has largely accounted for only banks and stock markets, ignoring bond market and non‐bank financial intermediaries. We find that bond market development affects economic growth in South Africa, and no similar effect is observed for the bank and non‐bank financial intermediaries and the stock market. Our finding shows that examination of individual elements of the financial system is important in understanding the unique effect of each on growth. The observation that the bond market rather than stock market, bank and non‐bank institutions promote economic growth in South Africa induces an intriguing question as to what unique roles bond markets play that the intermediaries and equity market are unable to play.     

An analysis of dynamic risk in the Greater China equity markets

This study looks at the time-varying nature of systematic risk in the Greater China equity markets. The Shanghai and Shenzhen markets both have a low average systematic risk when measured against the world market. The short outbursts in systematic risk for these two markets seem to be directly related to policy shifts. The Hong Kong and Taiwan markets are more integrated with world markets and they show signs of large variations in systematic risk over time. Furthermore, conditional betas in the Shanghai and Shenzhen markets are stationary, while the Hong Kong and Taiwan betas are integrated of order one. In addition, long memory tests show that all four markets exhibit a long-run dependence in their conditional betas. While the two mainland China market betas are covariance stationary, the Hong Kong and Taiwan betas are not.     

Stock Market Development and Economic Growth: The Case of Selected African Countries

Abstract: This paper studies the effect of stock market development on economic growth in 14 African countries in a dynamic panel data modelling setting. Results largely show a positive relationship between stock market development and economic growth. Further analyses, based on the level of economic development and stock market capitalization, are also conducted. The results reveal that the positive influence of stock market development on economic growth is significant for countries classified as upper middle income economies. On the basis of market capitalization groupings, stock market developments play a significant role in growth only for moderately capitalized markets. The general trend in results shows that low income African countries and less developed stock markets need to grow more and develop their markets to elicit economic gains from stock markets.     

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.

Does Intra‐regional Trade Matter in Regional Stock Markets? New Evidence from the Asia‐Pacific Region

We provide new evidence on the relationship between bilateral trade and stock market returns across the Asia‐Pacific region. Using three country blocs in this region, including the Far Eastern bloc, the Chinese bloc and the Australian bloc, we examine whether trade linkages between countries affect their stock returns. Incorporating two distinct dynamic properties of regime shifting and cointegration in intra‐regional trade and stock market returns, we employ the newly suggested multivariable smooth transition autoregressive vector error correction model (STAR‐VECM). A series of estimations reveals evidence that bilateral trade significantly Granger‐causes stock returns in the Asia‐Pacific region, with effects that are asymmetric depending upon the stock market regime and the country pair. Among the three blocs, the Far Eastern bloc displays a more pronounced positive effect of bilateral trade growth on stock returns than do the other blocs.     

Regional stock markets and the economic development of Southeast Asia

The paper examines the contribution made by the establishment and operation of a local stock exchange to the economic development of Southeast Asian (SEA) countries. The paper informs investors and policymakers about the current status of SEA stock market development and the associated positive and negative effects of such initiatives. Policymakers have placed a clear focus on SEA stock markets as a primary driver of regional economic growth. However, it is questionable whether SEA is ready for such an ambitious economic initiative, particularly given the reported negative effects of lesser developed stock markets. Despite these negative implications, the benefits appear to outweigh the costs for SEA stock markets. It is perceived that SEA stock markets will drive further economic reform, financial liberalisation, and market integration, promising tremendous benefits for both the region and the international investment community. The paper concludes with questions regarding the efficiency of stock markets in SEA and offers recommendations for further empirical research.

Assessing systemic risk and its determinants for advanced and major emerging economies: the case of ΔCoVaR

The paper examines conditional risk relationships among sovereign CDS prices and stock market indices for 11 economies with particular relevance for international portfolio investment holdings (Canada, China, Brazil, France, Germany, Italy, Japan, Russia, Spain, the USA, and the UK). The analysis is based on delta conditional value at risk (ΔCoVaR). The UK, France, and Italy significantly contribute to the overall systemic risk in both markets. The USA, the UK, and Russia appear to be important contributors to it in the stock market. In the meantime, the advanced economies exhibit much higher resilience to the systemic risk propagation in comparison with China, Brazil and Russia. Gross government debt to GDP, state fragility index, EU membership and world gross GDP share of a country in distress are key determinants of ΔCoVaRs for the sovereign CDS prices. Stock market total value traded to GDP and world gross GDP share of a country in distress drive ΔCoVaRs in the stock market. In both cases geographic distance tends to deter systemic risk propagation. Inflation, trade and financial openness as well as common language and time zone differences are less important predictors of bilateral ΔCoVaR exposures.     

Contagion or Real Linkages？ Some Evidence from China＇s Emerging Parallel Markets

This paper empirically tests the existence of contagion using data on China's five parallel markets with different entry barriers for foreign capital. Taking the 1997 stock market crash as our experiment and using data on A, B and H shares, red chips and American depository receipts, the present paper tests whether these China‐backed market returns respond differently to foreign shocks during the pre‐1997 and post‐1997 crash period. Evidence suggests that the contagion effects are stronger in markets with fewer entry barriers. An important implication of our findings is that countries vulnerable to contagion could be justified to impose some limits on capital flows.     

基于金融周期视角下股票市场的联动效应研究

世界经济全球化已成为趋势,发达经济体的股市之间以及发达经济体与新兴经济体股市之间的联动性也在经济全球化的趋势中更加紧密。各国金融领域以及金融市场间的快速融合,不断形成统一规范的金融行为准则,也使得全球金融周期性特征越来越明显。文章选取世界五个主要股票市场指数为研究对象,按照已有研究对全球金融周期的划分,将该样本区间分成了繁荣期、衰退期和正常期三个阶段,然后基于这三个阶段分析了在不同金融周期五国股票市场指数收益率联动效应。基于实证研究结论,认为美国和欧洲股市联动性较强,与亚洲股市联动性相对较弱,且美国和中国股市之间联动性最弱,基本捕捉不到下尾相关。相关实证结论有利于国际投资者的投资组合管理,也有助于各国股票市场的风险规避。     

Interaction between Foreign and Domestic Investors in the Korean Stock and Futures Markets*

The present paper analyzes the behavioral relations of major investor groups in the stabilized Korean stock and futures markets after the 1997 Asian financial crisis. Investor groups cannot be classified as positive or negative feedback traders on market returns when both stock and futures markets are considered, which is inconsistent with the results in Ghysels and Seon (2005). Foreign investors and domestic institutions tend to take opposite positions in both markets. The impact of foreign investors on the basis change is significantly negative in the futures market, whereas domestic institutions have a negative relation in the stock market. This supports the view that selling activity of foreign investors in the futures market pulls the futures price down compared with the index value and, consequently, induces the reverse cash‐and‐carry trade of domestic institutions. This relationship, which negatively influenced the Korean economy during the crisis, as shown in Ghysels and Seon (2005), still exists in the Korean financial markets.

The role of the Chinese economy in the world economy: A U.S. perspective

In this paper I first review the amazing progress that free market economic reforms have brought to the Chinese people after years of central control and suppression of markets. Thanks to greater economic freedom, economic growth increased sharply and hundreds of millions of people have been removed from poverty. By all accounts, however, economic freedom in China has a long way to go. The U.S. perspective should be that these market reforms continue. These further reforms toward economic freedom and economic growth in China will be beneficial to the United States. Such reforms would include a greater transparency about the monetary policy strategies, more openness of the capital accounts and less exchange rate and stock market intervention. Such economic reforms should be welcomed and encouraged by the United States and other countries.     

股市的节日效应探源:基于上证综指和深证成指收益率

采用上证综指和深证成指收益率数据,运用加权最小二乘法,对我国股票市场的节日效应进行研究,发现中国股市存在显著的节日效应。在研究中国股市的节日效应与周内效应的关系时,发现考虑了周内效应后,沪深两市的节日效应依然显著存在,节日效应并不是由周内效应引起的。通过结合不休市的传统节日研究发现,传统节日也存在显著的节日效应,因此,节日效应不是闭市效应的一种体现。
