投资选择权约束、意见分歧与中国股市风险

特定的股票总是被市场上特定的投资者群体持有 ,以反映该投资者群体对投资资产价格的评估意见。投资者意见的分歧会导致股票市场的资产出清价格偏离均值 ,股票价格趋于均衡的波动幅度也会变大。中国股市上投资者投资选择权的约束加大了投资者的意见分歧。扩大投资者的投资选择权来促进投资者意见分歧程度的缩小能有效降低中国股市的风险。

深圳股市对股权分置改革有何反应——来自第二批试点公司的实证检验

本文以深圳股市第二批试点公司为研究样本，通过赢家、输家股票组合超常日收益率的统计分析。以及累积超常日收益率的趋势分析，研究深圳股市对股权分置改革的短期反应。实证检验结果表明。在短期内，深圳股市存在过度反应。并且在公司股改预案披露后30个左右交易日，市场做出反向修正．     

风险承担、风险缓冲与管理理念——关于信托公司风险管理的思考

由于信托制度的独特设计,信托公司或直接或间接均要承担信托财产损失风险,从近期来看,信托公司应构建以资本金为核心的风险缓冲机制。从长期来看,引入业绩评价基准,进行相对业绩评价是信托公司风险缓冲的必然选择。信托公司在风险管理时应树立两个理念,一是要将风险管理列为企业管理活动的核心,二是要认识到风险管理是一项长期性的工作,不能寄希望“毕其功于一役”。     

会计价值机制论

本文认为,市场和企业是组织经济活动的形式,也是组织价值信息传递和价值激励的系统。市场价格机制是在长期市场供求关系作用下而形成的,而会计价值机制是随着企业的发展不断演化,在企业目标引导下组织价值信息传递和价值信息激励,以促成企业目标实现。企业替代市场或取得竞争优势,都是基于相同的原因和两种机制作用的结果,即是通过企业提供的产品或服务的成本低于市场价格而实现的。     

Order imbalance and stock returns: Evidence from China

We investigate the relation between daily order imbalance and return in the Chinese stock markets of Shenzhen and Shanghai. Prior studies have found that daily order imbalance is predictive of subsequent returns. On the two Chinese exchanges we find the autocorrelation in order imbalances is similar to that of the New York Stock Exchange as reported by Chordia and Subrahmanyam [Chordia, T., & Subrahmanyam, A. (2004). Order imbalance and individual stock returns: Theory and evidence. Journal of Financial Economics, 72, 485–518]. We also find a strong contemporaneous relation between daily order imbalances and returns. However, we do not find evidence that order imbalances predict subsequent returns. We attribute the difference in predicative power to differences in trading mechanisms on the two exchanges and to differences in the share turnover rates.     

Take a risk: Preferring prevention over control of biological invaders

Scientists have argued that invasive species can be managed most cost effectively with greater investments in prevention. Further, under ideas like the precautionary principle it is reasonable to expect that a cautious manager would use more prevention relative to control because it keeps more invaders out. Yet, this is not typically done. In many cases, private and public resources are invested primarily to control existing invaders rather than to prevent new invasions. Managers frequently wait until after invaders have arrived and then scramble to limit the damages. We believe these paradoxical decisions can be understood by recognizing the link between typical human preferences for risk bearing and the technology of risk reduction. We demonstrate quantitatively how managers perceived to be cautious or averse to risk tend to shy away from prevention relative to control. This counterintuitive result arises because control is a safer choice than prevention because its productivity is relatively less risky: it works to remove existing invaders from the system. In contrast, the productivity of prevention is more uncertain because prevention only reduces the chance of invasion, it does not eliminate it, and invasion may not occur even in the absence of prevention. Managers' averse to risk will inherently avoid as much uncertainty as possible, whether the source of uncertainty regards ecological outcomes or economic productivity. Implications for environmental decision making are clear. In invasive species management, if managers act as though they are risk averse, their caution can backfire when it leads to more control rather than prevention. The social consequences of this choice are a greater probability of future invasions and lower social welfare. Our results suggest that social welfare is highest when managers were willing to “take a risk” with prevention.

市场竞争、东道国引资政策与跨国公司的技术转移

在一个两阶段古诺竞争模型基础上,本文研究了东道国引资政策对跨国公司技术转移的影响,结果显示,跨国公司对东道国的技术转移取决于东道国市场竞争程度、本地企业的模仿能力与跨国公司的技术转移成本。在东道国企业模仿能力有限的情况下,跨国公司低技术的直接投资将损害东道国企业,从而降低东道国的国民福利水平;文章同时研究了市场竞争对跨国公司技术转移的影响,结果表明,对东道国来说,维持一个适度有序竞争的国内市场,同时对跨国公司的直接投资进行有选择地甄别与吸收,比单纯的竞争战略更有利于跨国公司的技术转移与技术扩散。     

Playing safe in coordination games:: the roles of risk dominance, payoff dominance, and history of play

This paper presents results from a series of experiments designed to test the impact on subject behavior of changes in the risk dominance and payoff dominance characteristics of two player coordination games. The main finding is that changes in risk dominance significantly affect play of the subjects, whereas changes in the level of payoff dominance do not. Observed history of play also has an important influence on subject behavior, both when subjects are randomly rematched after each game and when they remain matched with the same individual for a sequence of games.
