We argue that the Arrow– Pratt-concept per se well matches with economic intuition in standard financial decision problems, such as willingness to pay for insurance and simple portfolio problems. Different from the literature, we find that the widely-applied spectral Arrow–Pratt-measure is not a consistent measure of Arrow–Pratt-risk aversion. Instead, the difference between the antiderivatives of the corresponding risk spectra is valid. Within the framework of Ross, we show that the popular subclasses of Expected Shortfall, and exponential and power spectral risk measures cannot be completely ordered with respect to Ross-risk aversion. Thus, for all these subclasses, the concept of Ross-risk aversion is not generally compatible with Arrow–Pratt-risk aversion, but induces counter-intuitive comparative statics of its own. Compatibility can be achieved if asset returns are jointly normally distributed. The general lesson is that these restrictions have to be considered before spectral risk measures can be applied for the purpose of optimal decision making and regulatory issues. تاریخ ثبت: 1394/11/18 تعداد مطالعه: 254 تعداد دریافت: 0 حجم فایل : 841.48 KB گروه: دوره 58 ماه September دریافت فایل: همراه با تیم: عضویت طرح فیروزه کارتابل(میزکار) همراهان تیم دعوت از دوستان همگام با تیم:عضویت طرح یاقوت همیار با تیم: عضویت طرح زمرد همکار با تیم: عضویت ویژه الماس جستجو یار مالی شغلی مترجم یار مالی حسابداری تور مجازی ارتباط با تیم اجرایی دیدگاه کاربران نام: پست الکترونیک: * متن: * کد امنیتی: *
