Pricing factors in capital market and investment strategy： Evidence from Chinese listed companies

This paper explores the performances of some frequently used asset pricing factors and their investment implications in Chinese stock market. It is noted that CAPM model can hardly be applied to Chinese market as portfolios based on 13 values cannot generate high return against high risk. However, two factors （Size and B/M） from Fama-French model （1992） deliver better performances. Such findings indicate that models based on theoretical analysis are somewhat away from practice, and those risk factors from empirical studies are more applicable though not based on theories. Therefore, further researches are desirable concerning asset pricing factors.

The Fama-French’s five-factor model relation with interest rates and macro variables

Innovations in variables describing future investment opportunities command a risk premium and are correlated with Fama-French factors. As showed in literature, shocks to the aggregate dividend yield and term spread, default spread, and one-month T-bill rate are proxies for HML and SMB factors. However, in the context of five-factor model, they cannot explain RMW. As CPI is related to operational profitability, and so does RMW, we include its unanticipated shocks in the set of macro variables and factors to help explaining the cross section of returns. In the presence of CPI, RMW loses its explanatory power, and, combined with term structure’s slope innovations, all Fama-French factors lose their explanatory ability and the pricing errors become statistically close to zero. We show that for US data, inflation’s innovations not only proxy for RMW, but a model including only excess market returns, shocks to CPI and term structure’s slope explain the cross section of average returns better than innovations to the previous literature’s four-variable set and Fama-French five-factor model.     

Asset Pricing with Observable Stochastic Discount Factors

The stochastic discount factor model provides a general framework for pricing assets. By specifying the discount factor suitably it encompasses most of the theories currently in use, including CAPM and consumption CAPM. The SDF model has been based on the use of single and multiple factors, and on latent and observed factors. In most situations, and especially for the term structure, single factor models are inappropriate, whilst latent variables require the somewhat arbitrary specification of generating processes and are difficult to interpret. In this paper we survey the principal different implementations of the SDF model for bonds, equity and FOREX and propose a new approach. This is based on the use of multiple factors that are observable and modelling the joint distribution of excess returns and the factors using a multi–variate GARCH–in–mean process. We argue that in general single equation and VAR models, although widely used in empirical finance, are inappropriate as they do not satisfy the no–arbitrage condition. Since risk premia arise from conditional covariation between the returns and the factors, both a multi–variate context and having conditional covariances in the conditional mean process, is essential. We explain how apparent exceptions, such as the CIR and Vasicek models, in fact meet this requirement — but at a price. We explain our new approach, discuss how it might be implemented and present some empirical evidence, mainly from our own researches. Partly, to enable comparisons to be made, the survey also includes evidence from recent empirical work using more traditional approaches.     

浅析EVA在中国之“水土不服”

企业的经营与运作需要一个能真正反映公司业绩的评价指标。这一指标不仅能够作为公司经营决策的重要依据,而且能成为建立企业约束和激励机制的重要手段。由美国纽约思腾思特公司(SternStewart&Co.)所提出的EVA业绩评价指标可以在企业的激励方案中取代原有的业绩评价标准,以产生更为合理的结果。文中就EVA指标加以分析评价,同时指出其在我国企业实际应用中存在的问题,并提出几点建议。     

公司风险视角下上市国企管理层股权激励研究

在允许国有控股上市公司实施股权激励的背景下,考察了其不同种类风险与经营者股权激励强度的关系。先界定了风险的类型,再通过构建基于风险的两种股权激励模型,并进一步推导得出：若国有上市企业的管理层不能（可以）买卖公司以外的市场证券组合时,其最优股权激励强度与公司特别性风险成反向变化关系,而与公司整体性风险的相关关系不确定（无关）,这为正在实践中摸索的国有上市企业管理层股权激励合同的设计提供了进一步的理论建议。     

证券公司资产结构管理研究

对于具有资本密集和风险经营特性的证券公司而言,资产结构管理的研究对证券公司持续稳定经营有着重要的意义。本文通过系统聚类法分析了我国上市证券公司资产结构的相似性,并在此基础上进行了分类比较。研究结果表明:近年来,在行业竞争压力和业务创新的推动下,我国证券公司的资产结构出现了调整。同时,利用Kendall相关系数分析证券公司资产结构与ROE和风险管理指标之间的关系后表明:在净资本的约束下,证券公司资产结构调整是在对资本消耗和资本收益的权衡之下进行的,从制度和技术层面看,如何更好地加强证券公司资产结构管理至关重要。

More hedging instruments may destabilize markets

This paper formalizes the idea that more hedging instruments may destabilize markets when traders have heterogeneous expectations and adapt their behavior according to performance-based reinforcement learning. In a simple asset pricing model with heterogeneous beliefs the introduction of additional Arrow securities may destabilize markets, and thus increase price volatility, and at the same time decrease average welfare. We also investigate whether a fully rational agent can employ additional hedging instruments to stabilize markets. It turns out that the answer depends on the composition of the population of non-rational traders and the information gathering costs for rationality.

Effects of an anticipated expansion in international public goods on public capital accumulation

This paper presents a generic model to include public capital accumulation and the services of international public goods provided by a neighbor country. It examines the long-run and short-run responses of private and public capital accumulation in the home country to an anticipated increase in international public goods. It is found that the home economy in effect cuts its public capital stock, but keeps an unchanged private capital stock in the long run when a neighbor commits itself to expanding the stock of public goods in the future. The key factor determining the short-run responses of the home country is the extent to which it will match its government spending with a neighbor country's policy, which is associated with the relative difference between the marginal utility of consumption and that of home public capital affected by an increase in international public goods.
