The paper estimates the primary market pricing efficiency of China’s IPO after the IPO reform in June 2009, based on the stochastic frontier analysis. The results show that IPO pricing is not fully effective, and discover the existence of “deliberate underpricing”. The average pricing efficiency of China's IPO has reached 0.85, which is close to the level of the mature capital market; To certain extent, we can say that the reform of China's IPO has achieved the initial success. We also found that earnings per share and price earnings ratio are the greatest influencing factors. And there is no underwriter reputation in China. For different markets, we disclosed that, IPO pricing efficiency values in Growth Enterprise Market and Small and Medium Enterprise Board are substantially higher than the Main Board market. The paper analyzes the causes, and then gives some suggestions for the reform of China's IPO.

通过对Delong etc的噪音交易理论模型的修正，本文分析了投资者情绪对股票收益的影响机理。选择市场换手率、封闭式基金折价和投资者开户增长率作为间接投资者情绪指数，应用因子分析法构造综合投资者情绪指数，并应用OLS和GARCH-M回归分析方法对中国股市投资者情绪及波动与股票收益间关系进行实证分析。结果显示，投资者情绪是影响股票价格的系统因子，股票价格随着投资者情绪波动而波动，而且情绪的上涨和下降对股票价格的影响是不对称的，情绪上涨对股票价格的影响要比下降强的多；因投资者情绪波动而产生的股票收益波动构成市场系统风险并得到了相应的风险溢酬。

In this article, we consider a regulated market and explore the default events. By using a so-called reflected Ornstein-Uhlenbeck process with two-sided barriers to formulate the price dynamics, we derive the expression on the conditional default probability. In the cases of single observation and multiple observations, the conditional default probabilities are explicitly expressed in terms of the inverse Laplace transforms. Finally, we present a numerical simulation associated with the conditional default probability.

This paper studies trading and prices of dual/cross-listed stocks (i.e., equities from a single company that trade in more than one country). We focus on PRC rms with shares listed in Shanghai and Hong Kong. well-publicized index tracks the average price disparity across the two exchanges and shows signicant variation over time. We show that dierences in order imbalances (in Shanghai vs Hong Kong) explain contemporaneous changes in relative prices at daily and weekly frequencies. Our results help clarify liquidity-driven explanations from sentiment-based ones.

Firm diversifications are prevalent in many emerging economies in contrast to the practices in developed economies. A fundamental difference between these two types of economies is the existence of sound economic institutions including in particular property rights protection. Indeed it has been argued that diversified firms may thrive in situations of poor economic institutions, but much research is needed to substantiate this idea. In this paper, using a survey data set of private enterprises in China, we examine whether cross-region variations in the degree of property rights protection a¤ect the extent of firm diversification. We find that poorer property rights protection causes firms to be more diversified. We then explore several possible mechanisms through which property rights protection may affect firm diversification.

The purpose of this thesis is to provide an exposition of the theories underpinning the term structure of interest rates in relation to empirical literatures; also it aims to address the implications for the shape of the yield curve to with regard to its predictive ability of economy’s future direction.

A fundamental question in finance is whether and how removing market frictions is associated with efficiency gains. We study this question using share issue privatization in China that took place through the split share structure reform. Prior to the reform, domestic A-shares were divided into tradable and non-tradable shares with identical cash flow and voting rights. Under the reform, holders of the non-tradable shares negotiated a compensation plan with holders of the tradable shares in order to make their shares tradable. We hypothesize that efficiency gains in terms of better risk sharing play an important role in the determination of compensation. We show that the size of compensation is positively associated with both the gain in risk sharing and the price impact of more shares coming to the market after the reform, and is negatively associated with the bargaining power of holders of non-tradable shares and firm performance. Our study highlights the role of risk sharing in China’s share issue privatization.

It is well documented that bond excess returns are time-varying and that they can be explained by predetermined risk factors. This paper builds a theoretical model to forecast excess returns on treasury bonds in the context of China’s unique monetary system. Empirical evidence shows that bond excess returns in China are highly predictable when compared to those in developed markets. Further investigation suggests that the predicted components are primarily driven by the inflexible term structures of official interest rates set by China’s central bank.

With a sample of 504 IPO issuers over a period of 2002-2008 in China, this paper studies a previously ignored issue by examining the relationship between pre-IPO earnings management and underwriter reputation for issuers with different level of marketization. We document that underwriter reputation is negatively related to pre-IPO earnings management only if the issuer is highly marketized. Specifically, we find a significantly negative relationship between pre-IPO earnings management and underwriter reputation if the issuer is a non-state-owned enterprise (NSOE) issuer, a small-size issuer, or is listed on the Small and Medium Enterprise (SME) Board. No significant association is found for the state-owned enterprise (SOE) issuers, the large issuers, or Main Board issuers. We argue that the results are driven by the fact that issuers in the NSOE, small-sized, or SME market segment have more incentives to signal their earnings quality to avoid adverse selection by the investors, and/or reputable underwriters are more influential over their clients in mitigating earnings management.
