Multivariate Garch Models For The Greater China Stock Markets, Xiaojun Song Jan 2009

Multivariate Garch Models For The Greater China Stock Markets, Xiaojun Song

Dissertations and Theses Collection (Open Access)

This paper reviews the commonly used multivariate GARCH models and uses the daily data of the four Greater China region stock markets, namely Hongkong, Shanghai,Shenzhen, and Singapore, and data of Japan as one ex-ogenous variable to investigate the volatility and shocks spillover behavior and to establish the market linkage among the four markets. We find that the volatility spillover between Shanghai and Shenzhen is obvious and correlation contagion is detected. Conditional variance and conditional correlations are time varying and dynamic which conforms to the arguments in most of the literature. Shanghai and Shenzhen present a very high correlation level during …

The Effects Of Patent Characteristics As Signals On The Growth Of Follow-On Innovations: Evidence From Chinese Patenting Activities In U.S, Wenxin Guo Jan 2009

The Effects Of Patent Characteristics As Signals On The Growth Of Follow-On Innovations: Evidence From Chinese Patenting Activities In U.S, Wenxin Guo

Dissertations and Theses Collection (Open Access)

As global trade and business activities intensified, cross-national patenting activities have been playing an increasingly important role in the process of innovation accumulation and growth. However, few studies (to my knowledge) have examined the characteristics of cross-national patents and their relationship to the accumulation and growth of innovation, especially in the context of a developing versus a developed country.
Motivated by the anecdotal evidence and `Patent Signaling Theory'(Spence, 1973), I investigate the possible influential factors on the `quality' of a US patent with a Chinese priority (thereafter `US-CN' patent) and their impact on the growth of follow-on innovation. By developing …

Has The Introduction Of Bookbuilding Increased The Efficiency Of China's Ipo Pricing?, Jiehui Fei Jan 2009

Has The Introduction Of Bookbuilding Increased The Efficiency Of China's Ipo Pricing?, Jiehui Fei

Dissertations and Theses Collection (Open Access)

Book-building is commonly adopted in global primary markets and regarded as the most efficient pricing method for accurate IPO pricing by literatures. China has introduced book-building in 2005 to increase IPO pricing accuracy and the capabilities of domestic institutional investors. However, with the current IPO data from China, I find the level of under-pricing has unexpectedly increased after book-building, which is against the empirical studies of a few domestic papers. Secondly, there's some evidence that with better information disclosure from issuer-side through book-building process, the signaling and ex-ante uncertainty effect that previously caused under-pricing has been reduced. But there're unique …

Rolling Adf Tests: Detecting Rational Bubbles In Greater China Stock Markets, Peng Huang Jan 2008

Rolling Adf Tests: Detecting Rational Bubbles In Greater China Stock Markets, Peng Huang

Dissertations and Theses Collection (Open Access)

Following Phillips, Wu and Yu (2007), this paper extends their bubble detecting work to several Greater China stock markets. Two alternative bubble detecting methods, the forward recursive ADF tests raised by Phillips et al. (2007) and the modified version, forward rolling ADF tests, are implemented and compared. Monte Carlo simulations are performed to determine the critical values of the ADF statistic under different sample size. Empirical results demonstrate that only rolling ADF tests are successful in detecting rational bubbles by overcoming the problem of periodically collapsing bubble. As we have expected, bubbles in China Mainland stock market are detected. Out …

Moving Window Unit Root Test: Locating Real Estate Price Bubbles In Seoul Apartment Market, Shuping Shi Jan 2007

Moving Window Unit Root Test: Locating Real Estate Price Bubbles In Seoul Apartment Market, Shuping Shi

Dissertations and Theses Collection (Open Access)

Bubbles are characterized by rapid expansion followed by a contraction. Evans (1991) shows that stationarity tests suggested by Hamilton and Whiteman (1985) and Diba and Grossman (1988) are incapable of detecting periodically collapsing bubbles. Phillips, Wu, and Yu (2006) advanced the forward recursive unit root test which improves the power significantly in the presence of periodically collapsing bubbles. In this paper, we consider rolling window unit root test with a pre-selected optimum window. A combining use of conventional unit root test and forward recursive unit root test is suggested from the results of power comparison. Furthermore, we apply those three …

Information Value Of Credit Ratings In Asia Ex-Japan Markets, Chen Zhou Jan 2006

Information Value Of Credit Ratings In Asia Ex-Japan Markets, Chen Zhou

Dissertations and Theses Collection (Open Access)

This study investigates the information value of credit ratings by exploring the relationship between ratings and security price. Unlike previous studies, we concentrate on the major markets ex-Japan in Asia. We begin with an investigation of rating reclassification as well as credit watch placement events by three leading international rating agencies. We show that markets with differing level of sophistication behave differently. Specifically, South Korea and Hong Kong are found to respond in a similar manner. Indonesia shows possible ign of information leakage. In the cases of Malaysia and Thailand, significant and positive equity price responses exist for upgrades, suggesting …
