Abstract: | 在此篇論文中,我們實做了Chung 與Shih兩位博士於2007年三月所提出的GCRR (Generalized Cox-Ross-Rubinstein)二元樹模型,並應用此模型評價單障礙選擇權,以及推廣到評價雙障礙選擇權。 由於Ritchken 模型是目前市場上評價障礙選擇權最常用的模型,因此我們在評價障礙選擇方面做了GCRR與Ritchken 模型的收斂速度與計算時間的比較分析。我們發現,在單障礙選擇權方面,雖然Rithcken 模型能比GCRR 模型用更少的期間收斂到障礙選擇權的正確價值,但GCRR 模型的計算複雜度比Ritchken 模型的計算複雜度小,因此在同樣多的期間下,能以更快的速度算出答案。我們也建議了一個應用GCRR 模型來評價雙障礙選擇權的方式,雖然需要較多的期間才能獲得答案,但卻能以較短的計算複雜度來換取計算的效率。 In this thesis, we implement the GCRR model (Generalized Cox-Ross-Rubinstein binomial model) provided by Chung and Shih to price single-barrier options and double-barrier options. We compare the pricing results of the GCRR model with the Ritchken model. We find that although the Ritchken model converges to true price more quickly, the speed of calculation of the GCRR model is faster than the Rithcken model and uses less space. Moreover, we suggest a way similar to Ritchekn (1991) to pricing double-barrier options under the GCRR model. |
