英文摘要:
We give a pragmatic/pedagogical discussion of using Euclidean path integral in asset pricing. We then illustrate the path integral approach on short-rate models. By understanding the change of path integral measure in the Vasicek/Hull-White model, we can apply the same techniques to \"less-tractable\" models such as the Black-Karasinski model. We give explicit formulas for computing the bond pricing function in such models in the analog of quantum mechanical \"semiclassical\" approximation. We also outline how to apply perturbative quantum mechanical techniques beyond the \"semiclassical\" approximation, which are facilitated by Feynman diagrams.

中文摘要:
我们给出了在资产定价中使用欧几里德路径积分的实用/教学讨论。然后,我们说明了短利率模型上的路径积分方法。通过理解Vasicek/Hull-White模型中路径积分测度的变化,我们可以将相同的技术应用于“不易处理”的模型,如Black-Karasinski模型。在量子力学“半经典”近似下,我们给出了计算此类模型中债券定价函数的显式公式。我们还概述了如何将微扰量子力学技术应用于“半经典”近似之外,这是由费曼图促成的。
