1、大連理工大學(xué)博士學(xué)位論文死亡率關(guān)聯(lián)債券的定價(jià)模型與實(shí)證研究姓名:尚勤申請(qǐng)學(xué)位級(jí)別:博士專業(yè):管理科學(xué)與工程指導(dǎo)教師:秦學(xué)志20090601死亡率關(guān)聯(lián)債券的定價(jià)模型與實(shí)證研究(4)利用帶跳Feller過(guò)程和正雙曲利率模型,采用雙因子王變換構(gòu)建了長(zhǎng)壽債券的定價(jià)模型,并結(jié)合中國(guó)生命表數(shù)據(jù)進(jìn)行了實(shí)證分析。這一工作的優(yōu)勢(shì)主要體現(xiàn)在:帶跳Feller過(guò)程有利于進(jìn)一步改進(jìn)生存指數(shù)的刻畫,正雙曲利率模型更加符合我國(guó)貨幣市場(chǎng)的特點(diǎn)。綜上所述,本文著眼于人口死亡率隨機(jī)變化特征的描述并借助于金融市場(chǎng)、金融理論創(chuàng)新的優(yōu)
2、勢(shì),精心篩選并運(yùn)用了有助于死亡率關(guān)聯(lián)債券定價(jià)和風(fēng)險(xiǎn)度量準(zhǔn)確度提高的利率模型、王變換、Copula函數(shù)、帶跳的隨機(jī)過(guò)程等,并據(jù)此完善了死亡率關(guān)聯(lián)債券的設(shè)計(jì)且構(gòu)建了相應(yīng)的定價(jià)模型。實(shí)證結(jié)果表明,本文構(gòu)建的定價(jià)模型較其它已有模型在死亡率預(yù)測(cè)和基于不完全市場(chǎng)的債券定價(jià)方面均有一定的優(yōu)勢(shì),相應(yīng)的研究成果可為壽險(xiǎn)公司死亡率風(fēng)險(xiǎn)的管理提供新思路,有望用于解決壽險(xiǎn)公司償付能力不足、資會(huì)籌集通道不暢及流動(dòng)性不足等問(wèn)題,從而有利于提高我國(guó)壽險(xiǎn)公司的經(jīng)營(yíng)安全。關(guān)鍵詞:死亡率風(fēng)險(xiǎn);證券化;巨災(zāi)死亡率債券;長(zhǎng)壽債券大連理
