本論文在探討需支付維持費之美式選擇權評價。
支付維持費之美式選擇權有維持費和持有時間相關的成本,將會有提前履約和提前放棄的問題,為一個自由邊界問題,該問題之邊界須靠數值法求之。
本研究利用邊界積分方程(Boundary Integral Equation)以邊界元素法(Boundary Element Method)作為數值法,先解得買權邊界曲線,再求得此美式買權之合理價格,並以一例子去測試邊界元素法之可靠性,獲得不錯的結果。最後以股價、履約價格、股價波動率、無風險利率、維持費以及到期日等因素變化是否影響美式買權之價格相比較。
關鍵字:維持費、美式選擇權、邊界元素法
This paper is pricing of American option with maintenance fee.
maintenance fee and holding time are correlated with in American option with maintenance fee, there is question of early abandonment option and early exercise, it is a free border question, The boundary of this problem must be obtained by numerical method.
In my master thesis, a boundary element method is designed to evaluation American option with maintenance fee assets. Then we can obtain the call option boundary, this can evaluate the price of American option with maintenance fee assets. An example with exact solution is used to test the numerical method. The result is highly accurate. One practical examples is evaluated with this method. The results are used to compare with the valuation of other methods, and sensitive analysis for parameters is presented.
Key words:maintenance fee, American option, boundary element method
