风险投资在我国萌芽于80年代初。1985年3月,中共中央《关于科学技术体制改革的决定》中就指出:“对于变化迅速、风险较大的高技术开发工作,可以设立创业投资给予支持。”风险投资在中国20余年的发展为中小高科技企业的资金投入开辟了新的渠道,扶持了一批有很大潜力的民族高科技企业,对于促进我国新兴产业的发展,促进产业升级和结构高度化,起到了十分重要的作用。 相似文献

In recent years, both institutional andindividual investors have come to rely heavilyupon techniques for analyzing (defining andmeasuring) risk. In this respect, the issue thatcontinues to require the attention of academicresearchers and practitioners alike is how toconcisely define investment risk and, moreimportantly, how to best measure it. Selecting anappropriate risk definition involves trade-offsamong ease of measurement, forecast ability, andintuition of individual investors. The purpose ofthis paper is to present an alternative index formeasuring unconditional (or total) risk. Theproposed measure reflects behavior in general, andthickness in particular, of the lower tail of thedistribution of returns. We therefore argue itprovides a more useful and reasonable indexbecause, unlike measures frequently used, itsestimation depends upon the most relevant datafrom the sample distribution. We describe riskanalysis based on lower tail behavior and identifyits advantages over existing methods. Finally,using data of weekly returns to the CREF StockFund, we provide an empirical example toillustrate the technique. 相似文献

风险投资的信息经济学分析 总被引:2,自引:0,他引:2
新兴企业的融资市场上由于存在着较为严重的信息不对称现象,使得创业企业特别是高科技企业难以在传统金融市场上获得资金支持.而风险投资以其合理的机制设计较好地解决了资金供求双方的信息不对称,推动了高科技产业的迅猛发展.本文拟从信息经济学角度出发,解释该机制的内在合理性,以期对我国的风险投资的机制设计有所启示. 相似文献

This paper develops an optimal investment strategy for individuals concerned with avoiding the possibility of realizing returns below a predetermined target level within a prescribed period of time. Assuming a Brownian motion process, a model is developed which allows computation of the exact probability of failure. The algorithm and associated comparative statics with respect to the mean and standard deviation of returns, target return, time horizon, and risk-free rate of return are likely to have many useful practical applications. 相似文献

It is now widely accepted that contrarian, or value investment strategies deliver superior returns. Gregory, Harris and Michou (2001) examine the performance of contrarian investment strategies in the UK and find that value strategies formed on the basis of a wide range of measures of value have delivered excess returns that are both statistically and economically significant. However, while value strategies appear to be profitable, the reason for their superior perform‐ ance is far from clear. Under the contrarian model, value strategies are profitable because they are contrarian to naïve strategies such as those that erroneously extrapolate past performance, while under the rational pricing model, value strategies are profitable because they are fundamentally riskier in some sense. In this paper, we discriminate between these two possibilities by undertaking a comprehensive investigation of the relationship between the returns to value investment strategies and various macroeconomic state variables that in a multi‐factor asset pricing model could reasonably be taken as proxies for risk. Moreover, we examine whether the returns to value strategies predict future GDP, consumption and investment growth over and above the contribution of the Fama and French (1993 and 1996) SMB, HML and market factors. While the SMB and HML factors behave in a manner consistent with the rational pricing model, we show that some value strategies in the UK are able to generate excess returns that do not seem to be related to known risk factors. 相似文献

风险投资对我国高新技术产业发展起着越来越重要的推动作用.目前国内有关风险投资的研究大多集中在宏观层面,而对微观层面和实务操作的研究则较少.从实务操作层面而关键在于如何正确地评估风险投资项目的价值. 相似文献

自美国经济学家发现人力资本对经济发展的巨大贡献以来,人们的注意力主要集中于阐述人力资本投资的高收益性,而人力资本投资的风险性却很少被论及。实现有效的人力资本投资,必须建立在充分认识人力资本投资特点的基础上,而规避人力资本投资风险的根本途径是明晰人力资本产权和建立人力资本市场。 相似文献
