【摘要】 VaR和CVaR在国内外风险管理实践中得到了普遍应用,但监管者以概率置信水平作为其监管目标的方法对于实际投资者的风险度量而言并不是很直观,投资者更加关心的是资产目标价值能否实现的风险.将资产的目标价值以直观的方式加入到风险的定义中,提出了广义一致风险测度公理假设,并证明了广义一致风险测度也具有很好的性质.此外,看跌期权作为测度风险的有效方法,具有直观的经济含义,可以证明它满足广义一致风险测度公理假设.最后建立了看跌期权费风险测度和E-VaR/E-CVaR之间的数量关系.更多还原

【Abstract】 From an investor’s view,risk is closely related to his investment target.In this paper we take the investment target into the risk definition,and propose a new axiomatic framework for the class of generalized coherent risk measures.It proves that the class of generalized risk measure is consistent with the individual’s risk preference.The put option premium is an intuitive risk measure,and also is a generalized coherent risk measure.Connections between the put option premium and other risk measures such as E-VaR and E-CVaR are also built in this paper.更多还原
