Various studies have been done on wealth effects and financial performance of firms in different countries but have yielded mixed results. Data on completed deals of Cross-border Mergers and Acquisitions (CBMAs) comprising public listed firms with more than ten percent of share acquisition in five East Asian countries were analysed using event study and key financial ratios. Although the results for average abnormal returns in Indonesia and Korea were inconclusive, the results for Malaysia, Thailand and the Philippines suggest that the market had reacted positively adding value to the target firms at merger announcements. There was a significant improvement in targets’ free cash flow after CBMAs when compared to both before CBMAs and also control firms after CBMAs. The results also reveal that that these five East Asian countries have moved towards more efficient markets.

We examine the impact of cross-border mergers and acquisitions on a target firm’s risk and return based on a sample of partially acquired target firms in 18 emerging countries between 1990 and 2007. We find that cross-border acquisitions significantly reduce both the total and downside risk of the target firms and that this reduction is more significant in acquisitions undertaken by bidders from countries that have better protection of investor rights. We also show that this risk reduction improves the risk adjusted performance of these firms. Thus, we conclude that cross-border partial acquisitions benefit an emerging market investors’ risk-return trade off by reducing investment risk and increasing investment returns; policy makers in emerging markets may be well advised to open their markets for partial cross-border acquisitions.

In this paper, we empirically examine the relationship between government ownership, synchronicity and M&A performance in Chinese market. We found strong evidence to support “Helping Hand Hypothesis” that bidders with high government ownership yield better performance in both the short run and the long run. We also document a negative relationship between synchronicity measure and M&A performance. Various explanations have been offered to explain this phenomenon. In addition, we find both political influence and stock market valuation play an important role to forecast M&A outcome in China market. Within hot political period, government-related bidders yield better performance in the short run, while in high valuation period, public bidders receive higher premium.

In this paper, using data for the period January 1995 to May 2009 for the Shanghai stock exchange (SHSE), we show that aggregate illiquidity is a priced risk factor. We develop the relationship between the illiquidity factor, asymmetric information, and market collapse. Our empirical results show that while the illiquidity factor is a source of asymmetric information on the SHSE, asymmetric information does not trigger a market collapse.

If liquidity or illiquidity shocks reduce returns, then such risks need to be priced. The goal of this paper is to examine whether liquidity or illiquidity shocks increase or decrease returns on the Shanghai and Shenzhen stock exchanges. Our measure of illiquidity is the widely used Amihud’s (2002) ILLQ measure, and we proxy liquidity with the trading volume (TV), the turnover rate (TR), and the trading probability (TP). Using daily data for the period 1993 to 2003, we find weak evidence of the illiquidity shock having a negative effect on returns on both exchanges, and while greater cases of a positive effect of liquidity factors on returns is documented, very few of these are statistically significant. Hence, contrary to the extant literature, we find weak evidence in favour of pricing liquidity on the Chinese stock market.

Using block trades data on the Shanghai Stock Exchange (SSE) from 2003 – 2009, we study the pricing mechanisms of block buys and sells. We show that block trades are priced at discount (premium) for sells (buys). The discount/ premium varies depending on the characteristics of the stocks traded, the complexity of the trades, and also on whether the trades are internalized. We also study permanent and temporary price impact of the trades. As expected, seller-initiated trades do not seem to be information related as there is no significant information content. On the contrary, the prices decline after buyer-initiated trades, suggesting that buyers do not possess private information which leads to a permanent shift in prices. Temporary price impacts of all trades are large in magnitude and statistically significant, reflecting compensation for locating counterparties and the cost of negotiating terms. This suggests that the information platform on SSE for locating counterparties is yet to be fully developed to help reduce the transaction cost of block trades.

We hypothesize and test an inverse relationship between liquidity and price volatility derived from microstructure theory. Two important facets of liquidity trading are examined: thickness and noisiness. As represented by expected volume (thickness) and realized average commission cost per share (noisiness) of NYSE equity trading, both facets are found negatively associated with ex post and ex ante price volatilities of the NYSE stock portfolios and the NYSE composite index futures. Furthermore, the inverse association between volatility and noisiness is amplified in times of market crisis. The overall results demonstrate that volatility increases as noise trading declines. All findings retain statistical significance and materiality after controlling for a number of specifications. This inverse liquidity-volatility relationship reflects a microstructure interpretation of the liquidity risk premium documented in the asset pricing literature.

上海证券交易所于2006年7月1日开盘由封闭式集合竞价转为开方式集合竞价，文章以此开盘集合竞价透明度提高事件研究交易前透明度与价格发现效率之间的关系。研究发现：从事件前后的平均交易量、交易金额、流通市值和总市值对比看出事件后市场比较活跃，有更多的投资者参与，增加了市场的流动性。事件前后无偏回归结果系数β的比较分析表明交易前透明提高以后价格发现效率明显提高，交易价格更加有效，促进了价格发现。进一步运用基于方差分解方法得到的定价误差在事件前后也呈现显著性差异，即事件后的定价误差显著小于事件前的，这证明交易前透明度提高以后交易价格偏离有效价格的程度变小，进一步证明事件后价格发现效率确实提高。最后得出文章研究结论，交易前透明度提高以后价格发现效率显著提高。这进一步充实了交易前透明度研究的文献，同时对政策制定者提供了很好的参考价值，更对东亚新兴资本市场证券交易机制设计具有借鉴意义。

债券市场的首要功能是融资。目前我国的债券市场分为银行间市场和交易所市场，两者存在较 大的发展差距。本文以融资成本为对象，对两市场的企业融资效率进行比较研究。发现：银行间市场的显性发行成本低于交易所市场，但发行利率指导、发行垄断导致了隐性成本的增加；交易所市场由于投资者资金实力不足造成了发行利率水平的偏高，但证券公司自身的择时能力和债券需求的真实性确保了最低的隐性发行成本。
