摘要
在Denis(2007)提出的三参效用函数(FTP)的基础上,提出了五参效用函数(FFP).FFP可以描述更广泛的风险厌恶行为,它包含一种典型的双曲绝对风险厌恶效用函数(HARA)的情形,且是FTP的进一步推广.
This paper introduces a flexible five parameters utility function(FFP),which can be regarded as a generalization of the flexible three parameters(FTP) utility function of Denis(2007).In comparison with FTP,we can obtain a wider scale of risk aversion behavior.FFP includes the hyperbohc absolute risk aversion(HARA) family and can incorporate subsistence and saturation.Moreover,it is more flexible,as compared to FTP.
