基于熵定价方法,给出了一套平行Black-Scholes期权定价模型的利率上限、利率下限、利率双限与利率互换期权的估值解析式,并分别给出了它们的简化计算公式,为不完全市场中利率期权定价提供了一种新思路。
On the basis of the entropy pricing method, and swaption of interest rate are given with parallel to formula are presented respectively, which are offered a the analytical formula of valuing of caps, floors, collars Black-Scholes option pricing model, and their simplifying new way to price interest rate options in incomplete market.
