英文摘要:
We extend the classical Cox-Ross-Rubinstein binomial model in two ways. We first develop a binomial model with time-dependent parameters that equate all moments of the pricing tree increments with the corresponding moments of the increments of the limiting It\\^o price process. Second, we introduce a new trinomial model in the natural (historical) world, again fitting all moments of the pricing tree increments to the corresponding geometric Brownian motion. We introduce the risk-neutral trinomial tree and derive a hedging strategy based on an additional perpetual derivative used as a second asset for hedging in any node of the trinomial pricing tree.

中文摘要:
我们从两个方面扩展了经典的Cox-Ross-Rubinstein二项模型。我们首先建立了一个具有时间相关参数的二项模型,该模型将定价树增量的所有矩与限制It价格过程的相应增量矩相等。其次,我们在自然(历史)世界中引入了一个新的三项式模型,再次将定价树增量的所有矩拟合为相应的几何布朗运动。我们引入了风险中性的三项式定价树,并推导了一种基于附加永久性衍生工具的对冲策略,该衍生工具用作三项式定价树任何节点中对冲的第二资产。
