【摘要】:在本文中,我們考慮了一類具有投資收益的隨機(jī)保費(fèi)風(fēng)險(xiǎn)模型.假設(shè)市場(chǎng)的利率過程是一個(gè)非負(fù)Levy過程,我們分別用鞅方法和歸納法得到了破產(chǎn)概率滿足的非指數(shù)型上界,并用數(shù)值模擬的例子驗(yàn)證了該上界的有效性.此外,當(dāng)理賠額分布具有正則變化尾部時(shí),我們討論了有限時(shí)間破產(chǎn)概率的漸近公式.
[Abstract]:In this paper, we consider a stochastic premium risk model with investment income. Assuming that the interest rate process of the market is a non-negative Levy process, we obtain the nonexponential upper bound of ruin probability by martingale method and induction method, respectively. The effectiveness of the upper bound is verified by numerical simulation. In addition, when the distribution of claim amount has regular variation tail, we discuss the asymptotic formula of ruin probability in finite time.
