A股市场过度反应的新证据——基于A股和H股估值变化的视角

传统的检验市场过度反应的方法是采用De Bondt和Thaler构造的赢家组合和输家组合,通过检验赢家组合和输家组合的超额收益率来判断市场是否存在过度反应。有别于传统的检验市场过度反应的方法,本文基于我国股票市场上A股和H股估值变化的特殊视角,实证分析了我国A股市场存在的过度反应现象。     

人力资源管理外包供应商的选择指标实证研究

20世纪70年代以来,企业开始将一些非战略性人力资源管理工作转为外包运营,但如何选择合适的外包供应商,既能使企业可以利用外包创造价值,又能将风险减至最低,成为许多企业面对的难题。文章针对该问题以适合企业实际操作为目标,随机选取广东上市公司和在广东设立分支机构的世界500强企业的60家大型企业发放问卷,根据回收的53份问卷,探索性提出了一套由六个一级指标和十五个二级指标组成的人力资源外包供应商选择评价指标体系。

后危机时代我国政府治理模式的转型与定位——以政府与市场关系为观察视角

政府与市场之间的关系是国家治理所必须思考的首要问题,是治理模式选择的重要依据。政府和市场之间的权力边界的确定是双方力量均衡的结果,每一次市场的经济波动总会为二者关系的定位提出新的思考。2008年经济危机过程中,主张政府干预的凯恩斯主义登场并取得了一定成效。在后危机时代,面对低碳经济的发展要求,中国市场呈现出消费需求不足、城市化潜力释放缓慢、投资结构不合理等问题。所以面对各类市场需求,在后危机时代,政府应转变治理方式,权力触角逐渐淡出经济领域,让市场实现自我完善的同时进一步推进社会治理。     

信贷市场不完美，产业转型升级和经济增长

本文提出一个信贷市场不完美情况下产业升级的宏观经济模型,其中信用受限的经济主体可以选择不同类型的产业进行投资,产业类型的异质性体现在投资项目的生产效率、投资规模和信用担保程度。经济主体储蓄量的变化会改变信贷在不同生产效率的产业类型之间的分配,而资本在不同产业类型的组合效应造成不同的经济增长模式,包括从事低效产业的落后经济、从事高效产业的先进经济、从事多种产业的混合经济等。     

Market structure and rating strategies in credit rating markets – A dynamic model with matching of heterogeneous bond issuers and rating agencies

This paper investigates the impact of rating agencies in a market with asymmetric information. In particular, the role of credit rating agencies as an intermediary between investors and bond issuers is discussed. We model this setting in a dynamic framework in which both rating agencies and bond issuers are of heterogeneous quality. Rating agencies can apply costly research technology to reveal the fundamental nature of bond issuers and engage in rating smoothing. We show that rating smoothing can compensate for low research quality, even though it is accompanied by a quality deterioration in the rating market and market clustering. Moreover, low-quality bond issuers have a general tendency to match with low-quality rating agencies. If investors place a strong emphasis on the reputation of rating agencies, rating markets also tend to be strongly clustered.     

The securitization of gold and its potential impact on gold stocks

We study the market impact of a very successful financial innovation – the SPDR Gold Trust exchange-traded fund (GLD). GLD holds physical gold, and provides traders with a convenient and cost-effective way to gain exposure to gold. We find that after the introduction of GLD, the liquidity of gold company stocks declined, and their adverse-selection risk increased. Over the two-month period after GLD’s introduction, the stocks’ relative effective bid-ask spreads increased by over 15%, while their adverse-selection cost, as measured by the price impact of trades, went up by more than 30%. Gold stocks also experienced significant negative abnormal returns (−12% on average) in the month after GLD started trading. Our findings suggest that GLD attracted traders, especially uninformed traders, away from gold company stocks, and that the resulting negative demand shocks and decrease in the stocks’ liquidity caused their prices to decline. Our results show that existing securities can be seriously adversely affected when a new security enters the market.     

Pitfalls and perils of financial innovation: The use of CDS by corporate bond funds

We use the financial crisis of 2007–2009 as a laboratory to examine the costs and benefits of teams versus single managers in asset management. We find that when a fund uses complex trading strategies involving the use of CDS team-managed funds outperform solo-managed funds. This may be due to the greater diversity of expertise, experience and skill of teams relative to single managers. During the financial crisis, however, the performance premium of teams becomes negative, which may be because of the slower decision times of teams, which are especially costly during times of rapidly changing market conditions.     

On the efficiency of intra-industry information transfers: The dilution of the overreaction anomaly

We revisit the stock market anomaly documented by Thomas and Zhang (2008) and show that the apparent mispricing of information transfers has decayed over time, as the US markets experienced rapid improvements in the efficiency of the underlying price formation processes. Utilizing recent advancements in market microstructure research to estimate firm-specific proxies for market efficiency, we demonstrate that the existence of the overreaction anomaly (where stock prices of late announcers in response to the earnings reported by early announcers in the same industry are negatively related to subsequent price responses of late announcers to their own earnings reports) is specific to an earlier sample period and results from the inefficient incorporation of information into prices, largely attributable to an environment with high barriers to arbitrage. Our results indicate that the pricing efficiency of intra-industry information transfers has increased in the recent years of increased liquidity and markedly higher trading activity.     

Foreign Direct Investment in the Enlarged EU: Do Taxes Matter and to What Extent?

Foreign direct investment is of increasing importance in the European Union. This paper estimates the effect of taxes on foreign direct investment (FDI) flows and on three sub-components of these flows for the countries of the enlarged European Union. The model in the spirit of gravity equations robustly explains FDI flows between the 25 member states. Sample selection needs to be addressed in the estimation. We show that the different subcomponents of FDI should and indeed do react differently to taxes. After controlling for unobserved country characteristics and common time effects, the top statutory corporate tax rate of both, source and host country, turn insignificant for total FDI and investment into equity. However, high source country taxes clearly increase the probability of firms to re-invest profits abroad and lower the percentage of debt financed FDI. This might reflect profit re-allocation to avoid taxes. Market size factors have the expected signs.
