It also presents the process that the Legendre transform and dual theory can be applied to find an optimal investment policy during a participant＇s whole life in the pension plan. Finally, two explicit solutions to exponential utility function in the two different periods （before and after retirement） are revealed. Hence, the optimal investment strategies in the two periods are obtained.展开更多
权证定价无论在业界和学界都是一个十分重要的问题。利用沪市2006年发行备兑认购权证的六支股票作为标的,实证分析股票价格行为。结果表明CEV(Constant Elasticity of Variance,常方差弹性)模型比对数正态假定能够更好地描述股票价格。...权证定价无论在业界和学界都是一个十分重要的问题。利用沪市2006年发行备兑认购权证的六支股票作为标的,实证分析股票价格行为。结果表明CEV(Constant Elasticity of Variance,常方差弹性)模型比对数正态假定能够更好地描述股票价格。在此基础上,利用模拟分析对权证进行了定价,并将定价结果和B-S公式进行了比较。最后给出了对策和建议。展开更多

文摘The constant elasticity of variance（CEV） model was constructed to study a defined contribution pension plan where benefits were paid by annuity. It also presents the process that the Legendre transform and dual theory can be applied to find an optimal investment policy during a participant＇s whole life in the pension plan. Finally, two explicit solutions to exponential utility function in the two different periods （before and after retirement） are revealed. Hence, the optimal investment strategies in the two periods are obtained.
