• 详情 Information Transmission in Informationally Linked Markets: Evidence Based on Non-Synchronous Trading Information
    This paper investigates information transmission and price discovery mechanisms in informationally linked and non-synchronous trading markets within the multivariate generalized autoregressive conditional heteroskedasticity framework. Using daily data for copper and soybean contracts from the Chinese futures and spot markets, as well as the London Metal Exchange (LME) and Chicago Board of Trade (CBOT) futures markets, we show that there are asymmetric lead-lag relationships between any two of the three markets. We also find that the volatilities spill over from one market to another for both cases of copper and soybeans. However, the copper and soybean markets exhibit quite different patterns of information transmission. Further, we highlight the remarkable role of the Chinese futures markets in the price formation process, though the LME/CBOT futures markets are the main driving force in price discovery.
  • 详情 基于VaR—GARCH模型对国际原油期货的风险分析
    基于金融时间序列的实际分布的尾部明显更厚,而峰度则更高的特征,我们可以运用在不同的分布假定下的GARCH模型的VaR计算方法来对市场的风险进行分析。本文利用GARCH族模型以国际原油期货的日收益率数据分别在t-分布和广义误差分布(GED)条件下来度量原油期货的在险价值VaR。在验证了多个模型和二种分布组合之后,得出了GARCH(1,1)-t分布模型对原油期货能较好的拟合和反映出国际原油期货收益率的风险特征性。
  • 详情 The Effect of Social Pressures on CEO Compensation
    This study analyzes the effect of social pressures on CEO compensation focusing on social interactions within 60 miles of the firm. Social premiums in CEO pay are in excess of what can be explained by firm performance and characteristics, corporate governance, and local economic variables. Using the S&P 500 companies during 1994-2005, we show that the average social premium in a social circle with 31 CEOs (the 75th percentile of social circles) is $1.29 million higher than that in a circle with six CEOs (the 25th percentile). Golfing, sharing directors, and comparing mansions are likely avenues of social interactions.
  • 详情 Stock Index Reconstitution Effects in Emerging Market --- Empirical Study Based on CSI 300
    This paper investigates market effects associated with China Security Index 300 (CSI 300) reconstitutions with sample period from April 2005 to Feb 2008. Several findings are listed as followings: Firstly, cumulative abnormal returns for added stocks increase slightly after announcements, while the returns for removed stocks decrease significantly though reverse immediately after index reconstitutions. Considering the whole event period, prices for deletions do not fall dramatically; it’s consistent with asymmetric change of investors’ awareness proposed by H Chen et al (2004). Secondly, both the results of cumulative abnormal returns and volume ratios do not provide evidence to support price pressure hypothesis or index membership hypothesis. We attribute those results to few funds tracking stock indices exactly with the same components and weights as which in the underlying indices in emerging markets, i.e., enhanced index funds are more familiar. Thirdly, the percentage of the additions’ (or deletions’) shares held by funds is not affected obviously by CSI 300 reconstitutions. Finally, we examine index change effects due to IPO that frequently occur in emerging markets, and find that additions witness a full reversal after the first trading day.
  • 详情 Bubble Diagnosis and Prediction of the 2005-2007 and 2008-2009 Chinese Stock Market Bubbles
    By combining (i) the economic theory of rational expectation bubbles, (ii) behavioral finance on imitation and herding of investors and traders and (iii) the mathematical and statistical physics of bifurcations and phase transitions, the logperiodic power law (LPPL) model has been developed as a flexible tool to detect bubbles. The LPPL model considers the faster-than-exponential (power law with finite-time singularity) increase in asset prices decorated by accelerating oscillations as the main diagnostic of bubbles. It embodies a positive feedback loop of higher return anticipations competing with negative feedback spirals of crash expectations. We use the LPPL model in one of its incarnations to analyze two bubbles and subsequent market crashes in two important indexes in the Chinese stock markets between May 2005 and July 2009. Both the Shanghai Stock Exchange Composite index (US ticker symbol SSEC) and Shenzhen Stock Exchange Component index (SZSC) exhibited such behavior in two distinct time periods: 1) from mid-2005, bursting in October 2007 and 2) from November 2008, bursting in the beginning of August 2009. We successfully predicted time windows for both crashes in advance [24, 1] with the same methods used to successfully predict the peak in mid-2006 of the US housing bubble [37] and the peak in July 2008 of the global oil bubble [26]. The more recent bubble in the Chinese indexes was detected and its end or change of regime was predicted independently by two groups with similar results, showing that the model has been well-documented and can be replicated by industrial practitioners. Here we present more detailed analysis of the individual Chinese index predictions and of the methods used to make and test them. We complement the detection of log-periodic behavior with Lomb spectral analysis of detrended residuals and (H, q)-derivative of logarithmic indexes for both bubbles. We perform unit-root tests on the residuals from the log-periodic power law model to confirm the Ornstein-Uhlenbeck property of bounded residuals, in agreement with the consistent model of ‘explosive’ financial bubbles [16].
  • 详情 Listing BRICs: Stock Issuers from Brazil, Russia, India and China in New York, London, and Luxembourg
    In the last decade hundreds of companies from emerging markets have listed and issued their shares on American and European stock markets. Brazil, Russia, India, and China have been the main origins of issuers, and stock exchanges in the US, UK, and Luxembourg the main destinations involved in the process. These four home and three host markets are the empirical focus of our paper. We present an economic geography perspective on foreign listing, grounded in the geography of finance and the world city network approaches, emphasising the sub-national origins of foreign listed firms, the role of intermediaries, and competition for foreign listings. Our analysis, based on comprehensive up-to-date datasets on foreign listings and foreign equity issues, shows that issuers listing their shares abroad are predominantly large firms, coming from relatively high-growth, internationally oriented sectors, and headquartered overwhelmingly in the leading economic centres of their home countries. Key intermediaries in the foreign listing process are the global investment banks, operating out of the very same centres where the cross-listing firms and the host stock exchanges are located. Competition between host stock markets is affected significantly by the direct and indirect costs of foreign listing, including disclosure and corporate governance requirements. Both host markets and intermediaries exhibit a significant degree of specialisation in terms of the size, sector, and geographical origin of the issuers they serve. The market for foreign listing differs significantly between the BRIC countries, with the Chinese market offering the greatest potential, but facing considerable uncertainty.
  • 详情 Spillovers of the U.S. Subprime Financial Turmoil to Mainland China and Hong Kong Sar: Evidence from Stock Markets
    This paper focuses on evidence from stock markets as it investigates the spillovers from the United States to mainland China and Hong Kong SAR during the subprime crisis. Using both univariate and multivariate GARCH models, this paper finds that China's stock market is not immune to the financial crisis, as evidenced by the price and volatility spillovers from the United States. In addition, HK's equity returns have exhibited more significant price and volatility spillovers from the United States than China's returns, and past volatility shocks in the United States have a more persistent effect on future volatility in HK than in China, reflecting HK's role as an international financial center. Moreover, the impact of the volatility from the United States on China's stock markets has been more persistent than that from HK, due mainly to the United States as the origin of the subprime crisis. Finally, as expected, the conditional correlation between China and HK has outweighed their conditional correlations with the United States, echoing increasing financial integration between China and HK.
  • 详情 Impact of the US Credit Crunch and Housing Market Crisis on China
    There are many similarities between the US, the UK and the Chinese housing markets, including the movements of interest rates and house prices. Some Chinese banks, especially the Bank of China, have been exposed to the US mortgage securitization market. These have triggered a serious concern as to whether the US credit crunch and housing market crisis may be replicated in China. This paper shows that there are some significant differences between China and the West, especially the US and the UK. Compared with the US and other western industrialized economies, the booming house market in China has been supported by fast economic growth, rapid urbanization and high domestic savings. In addition, Chinese banks are less exposed to mortgage defaults than their western counterparts because house buyers are mainly urban and high income residents who are required to have high down payments. These Sino-Western economic and social differences suggest that the US credit crunch and housing market crisis may have some negative impacts on Chinese commercial banks and the overall economy but are unlikely to cause a similar financial and housing crisis in China despite the current struggling Chinese stock markets and a slowdown of house price growth.
  • 详情 Estimating Equity Risk Premium:the Case of Great China
    The expected equity risk premium is a key input of many asset prcing models in finance. There exist a number of methods to estimate the risk premium. It is also well documented that the risk premium is time-varying. This paper briefly reviews two different approaches. More specifically, the historical average and relative estimation are taken into closer examination. The first approach is applied to estimate equity risk premium for stock markets in Great China when the stock markets were recovering from the bottom. Then the relative estimation approach is also adopted to empirical data to justify the findings in the first one, which takes into consideration the lower required rate of return for Chinese investors due to lack of investment opportunities. After making these adjustments, we find that risk premium in mainland China is close to risk premium for Hong Kong and Taiwan markets. All of those markets have higher risk premium compared to US market. The risk premium for Shanghai and Shenzhen market are about 8% and 10% respectively. For Hong Kong and Taiwan these numbers become 8% and 9%, where the long-term forward-looking risk premium for US market is about 4%.
  • 详情 The Price Impact of Mutual Funds: Evidence from China
    The paper examines the price impact of mutual funds in the Chinese equity market from 2000 to 2007. We find there is strong positive correlation between stock returns and mutual fund holding and trading, and the price impact is more significant in mutual-fund buying than mutual-fund selling. Our findings support the hypothesis that the price impact is due to the information advantage of mutual funds.
