本文从传统的计价货币选择理论入手,对有关国际贸易计价货币选择的文献进行了综述。研究发现，货币的交易成本、产品的需求弹性、预期利润、讨价还价能力和市场占有率是国际贸易中企业计价货币选择的微观影响因素；而通货膨胀高低、货币供给波动大小和汇率波动程度是宏观影响因素。在微观企业计价货币选择的决策中融入宏观经济变量的动态一般均衡模型研究，以及微观企业时间序列数据的挖掘是未来计价货币选择理论的研究方向。

资产价格泡沫是目前各国央行面临的最大挑战之一，经济学界至今尚不能提供一种实时可信地识别泡沫的方法。目前中国的股票市场和房地产市场剧烈动荡，泡沫越来越成为引起全社会焦虑的主要问题之一。然而对于中国现阶段是否存在资产泡沫（尤其是房地产泡沫）这一问题却众说纷纭。如果不能早期实时地识别泡沫，央行在制定应对泡沫的政策方面就不可能有实质性进展。与西方各种泡沫理论和方法不同，本文提出了明确的现实性的泡沫定义，通过对资产的不同类型需求的分析，论述了泡沫现象的本质及其产生的必要条件和充分条件。在此基础上建立了一种简单的、早期的、没有虚假信号和漏测误差的实时识别泡沫的方法，并且用经验研究对该方法进行了初步的验证。

This paper investigates CEO pay and pay-performance relationship in China’s listed firms. We distinguish four firm types based on their controlling owners: state owned enterprises affiliated with state asset management bureaus (SAMBs), state owned enterprises affiliated with the central government (SOECGs), state owned enterprises affiliated with a local government (SOELGs), and private firms controlled by private investors. We also distinguish between firms with foreign investors and those without. Because the different types of controlling owners have different objectives, motivations, and political interests, they affect managers’ compensation in the firms in which they invest. Our results indicate that CEO pay is lowest in SAMB controlled firms and highest in SOECG controlled firms. Not only is CEO pay positively associated with firm performance, the positive pay-performance relationship is stronger in both types of SOE firms but weaker in privately controlled firms. In addition, firms with foreign investors compensate their CEOs more highly than those without foreign investors, an effect that is significant in both SOEs and privately controlled firms. Overall, the evidence suggests that CEO compensation in China is jointly determined by firm performance, market-oriented reform and the unique ownership structure, meaning that standard theories of efficient compensation contracts may not apply in such emerging markets.

本文在中国股权分置改革的背景下，建立股票供给和需求的理论模型，分析在需 求和供给变动两个冲击下，流通股股东的累积超额收益。我们进而利用市场模型和市场调整 模型计算流通股股东在股改复牌前后的累积超额收益，并分析检验其截面影响因素。实证检 验发现，累积超常收益和远期股票供给量成负相关关系。在控制流通股供应冲击效应之后， 我们发现公司盈利能力和非流通股集中度与股改价格效应负相关。进一步考虑市场时机和内 生性问题后，结论仍然稳健。本文创造性地度量了股权分置改革经济价值的市场预期，并提 供了需求曲线斜率为负的经验证据。

本文从风险与收益相匹配的视角，给出了基金经理进行资产配置的原则和理论模型，并据此设计出了判断基金资产配置能力高低的标准。然后对我国54只封闭式基金的资产配置能力进行了实证检验，发现中国的封闭式基金大部分具有较高的资产配置能力；研究同时得到中国的证券投资基金主要通过投资组合中证券的调整实现资产配置的原则，而较少依靠对组合中资产的调整来满足资产配置的原则要求。

本文分析了在所有权和控制权分离的情况下i=信息披露质量对于代理成本得影响，在初步的多元回归分析中，我们控制了影响代理成本的公司治理变量和公司特征后，发现高质量的信息披露可以显著的降低成本。在进一步的实证分析中，我们考虑了回归分析中可能存在的自选择问题，采用Heckman两阶段回归，发现高质量的信息披露对于降低代理成本的效果更佳显著。可见，提高资本市场信息披露质量，对于缓解代理成本问题有着非常重要的意义。我们的研究为信息披露质量与代理成本只讲的关系提供了直接的经验证据。

现代企业所有权与经营权分离的治理特征使得经理人的选择对有效实现股东利益最大化的经营目标至关重要,通过选择合适的管理者并在必要的时候对其进行变更是股东保障自身利益，规制经理人行为的重要手段。多元化企业的经理人选择行为较单一化企业更加复杂，本文考察了多元化对经理人变更的影响，并从我国股票市场的特点出发，考察政府控制对上市企业管理行为的影响。实证结果表明，多元化和政府控制因素均对经理人变更及变更后的绩效有显著影响。

The People’s Republic of China has taken substantial steps to reform its financial system, especially the banking sector, since 1995. The speed of banking reform has accelerated after China joined the World Trade Organization (WTO) in December 2001. This study examines the impact of recent banking reforms and of WTO accession on the cost efficiency of the Chinese banking sector. We use a non-parametric approach to investigate the efficiency trend and productivity growth of banks in China between 1998 and 2006. We also compare the efficiency and productivity growth of different banking ownership groups prior to and after joining the WTO. We find that, on average, domestic banks outperform their foreign counterparts over the sample period in terms of overall and allocative efficiency, but they fall behind in terms of overall technical efficiency. The comparison of efficiency indexes pre and post WTO accession reveals that the efficiency of domestic banks has declined post accession, while foreign banks have enjoyed an improvement rise in their cost efficiency post WTO accession in 2001.The findings of this study further suggest that the total factor productivity of Chinese banks has weakened over the period under study. However, a pre and post analysis of WTO accession results shows that total factor productivity has improved for both domestic and foreign banks after China joined the WTO, equally owing to efficiency improvement and technological progress
