摘要: | 本文提供了一個靈活的多因子隨機波動度Heath–Jarrow–Morton模型,此模型讓遠期利率與其波動度具有相關性,且有N個隨機因子會影響利率結構,另有額外N個隨機因子會影響波動度(及利率衍生性商品)。此模型改進了Trolle and Schwartz (2009)的模型,讓利率波動度與短期利率(short rate)水準有正比關係。此模型能夠轉換成有限狀態變數(finite number of state variables)的馬可夫表現(Markov representation)系統,故能輕易地使用蒙地卡羅模擬法來評價各種利率衍生性產品,如利率上限選擇權、利率交換選擇權等。最後我們會分析各參數對評價結果的影響。 This article provides a flexible stochastic volatility multi-factor Heath–Jarrow–Morton term structure model, which allows forward rate correlative with its volatility, and there are N random factors affect the interest rate structure, while additional N random factors would affect volatilities (and also interest rate derivatives). This model improves the Trolle and Schwartz (2009) model, so that interest rate volatility is proportional to the short rate. This model can be converted into a finite-state variables Markov representation system, so under this model, Monte Carlo simulation can be easily used to evaluate the various interest rate derivatives, such as interest rate cap, swaption, etc.. Finally, we will analyze the impact of various parameters on the pricing result. |
